90+ percent of the time, the sensors are killed by letting the gauge "warm up" the sensor before starting the engine. Nobody tells you ( except me ) that "warmed up" means GLOWING ORANGE HOT 1200F. AND that the sensor element, inside, is CERAMIC. So, turning the ignition on and letting it set there for a few seconds, before starting the engine causes the HOT ceramic element to get hit with a rush of cold exhaust ( and, usually some condensation water ). This causes fractures in the ceramic element. The cracks grow on every heat cycle, like windshield cracks. First, the sensor loses accuracy, because of air leaks. Then, eventually, the cracks hit something REALLY important. And, the sensor will just show FULL LEAN, 14.7, or FULL RICH. They usually start out being finicky about EGT.
@@awautoworks4426 Just follow the normal installation. The trick is to never leave the ignition on for more than a few seconds before starting the engine, As soon as the WB gets power, it starts heating the sensor. Original equipment ECU WBs know when the engine is running ( Because they are in the ECU ). So, they don't start heating up until after the engine is running. Aftermarket WBs, generally, don't know if the engine is running, or not, until it is too late. If you have left the gauge on, for more than a few seconds, without starting the engine, power it off, for at least 30 seconds, to let the sensor cool down to just scalding hot, before starting. If you see an AFR number, or " - - - -" , the sensor is, generally, already at full temp.
Turbo Grocery ...or you can wire in a switch so that you can turn it on yourself a short time after starting the engine. I turn mine one around 20 seconds later. This kind of mimics the stock ECU only activating the wideband after exhaust is warm. I wired mine through a relay, which is generally recommended, but put in a simple on/off toggle switch (or you could use a rocker switch).
So I just had the same problem. I performed all the same checks as he did and my issue was the O2 SENSOR. I am willing to bet that the new sensor he got was also defective. The directions tell you which sensor to buy and I was able to get mine at autozone. Buy 3, return 2 once you get it working. ☺️
AEM Fuel Ratio is the worst. I'm having the same problem in my 1970 Nova SS . AEM sent me a sensor but before they did I had to take a video of me cutting the harness as close to the sensor as possible. I installed the new sensor they sent and what else, the same problem. Now AEM wants me to take a video smashing the gauge before they send a new one. I told them I tested the gauge and it is working properly as per specs. It fails only when sensor is connected to it. It is doing exactly what the last sensor did to it. I asked for a new sensor and the guy said that it's not the sensor because we replaced it with a new one. I told him that just because it's new doesn't mean it is good. As an aircraft engineer with 40 years of experience I trust old parts that are proven to work correctly, then a new part. He told me that he is the expert on this AEM part and he is not supporting me. I told him to go jump in a lake and put the Guage kit on my wall with a note to all customers not to buy or trust anything made by AEM.
I wish I saw this before I bought my gauges I'm having issues w my wideband now lol. And the oil pressure gauge already replaced the sensor one time and looks like I might need to change it again bc is acting up.. do you still run aem on blue? Or do you run something else now
Just got another one for my other car. The original still works flawlessly. New one leans out whether car is running or not. Hooked the new sensor up to my old gauge and it leaned out almost instantly. The sensor is dead. Probably during shipping, because many delivery drivers drive like maniacs with packages flying everywhere and these bosch lsu 4.9 sensors are very very sensitive to being dropped.
Have had similar issued in the past, actually had a meeting with AEM and it is the sensors. They're releasing a new updated sensor here in the next few weeks
Buy the nascar bosch lsu 4.9 they are more robust. Being banging one tuning cars for over two years now. Its all banged up from falling out of tailpipes multiple times while road tuning and it still works like a charm. You are most welcome.
You can buy it used caz new costs even more than a complete new gauge. Dont worry whoever used it before does not have the capabilities to harm it, its indestructible.
ok so swapping gauges and wires didnt work, did the actual sensor get swapped for a new one? after the montage it just jump cuts to him saying he will put some other old one or the same one in? did a new sensor go in?
I have the same gauge in my evo 8. Car is barely driven. Maybe 5000km on the sensor/gauge and it’s gone to shit. On start up it goes from 14.7 to off the dial lean. Contacted the place I bought it from and was told it’s a wear and tear item so nothing can be done. Really annoyed cause it’s not a cheap setup.
I had the same problem my arm was sticking on 14.7 and I looked at the connectors and where the pins on the gauge plug into the pigtail they needed tweeking the 2 end pins weren't making contact.
I know this is pretty old, but I am literally having the exact same problem. But I start at 14.7 then it shoots Lean Back Down shoots lean then goes blank did you ever find out a solution? I'm still chasing this down literally just walked in the door

Smeedia, I’ve been running E85 in my 2015 FRS for 5 yrs. delicious flex fuel tuned. Went from my sprintex supercharger 287/232 Trq back to N/ A to learn better car control at track events. My son surprised me with a current SBD turbo kit. I’m finishing up my supporting mod purchases before my install myself next month. I’m retired Air Force aircraft mechanic so I’m up to the task. I’m adding an oil temp gauge and of course boost gauge. Now I’m all screwed up in so much as adding a decent AFR gauge. I know I’m damn sure not going AEM. I’m asking you which gauge/ sender kit do you recommend now, which ones are compatible with E85. I damn sure don’t want to go through this headache 3 , 4 times. I was initially thinking pro sport gauges due to their electronic box as easy access. Need help here amigo. Thx in advance.
So I love the AME gauge itself but the sensors are trash. For me I used the AEM pig tail with a Bosch sensor I bought off of amazon and spliced the two together. Used it in my STI on E85 Nd had no issues with sensor failure. I use thr same Frankenstein of a sensor in my turbo BRZ and it handles the heat very well. If your using ECU Tek for your FRS you can monitor oil temp from the app on your phone as well. 🙏
As for proportion ive never been a huge fan of them, I like guages that stand out and are quick to reference when driving. But prosport has a good reputation, not too sure on what sensors they use though
Smeedia thx bud as always, I’m running the delicious flex fuel app for ethanol content and presure on my I phone. So that screws me up for having my phone tied up damn it. I wish I could find away to add an ethanol permanent gauge to the delicious flex fuel set up without the Bluetooth operation. Without having to but a complete different E85 kit. My problems ha ha I’m rambling. But thx sir
Smeedia I’m Ecutek tuned but not via the blue tooth I’ve got the old cable set up and update it every other month. I guess it’s time to update more money spent 😁
I feel your pain, I have the same issues with a grams performance A/F gauge. I believe it might be a bad sensor, was working fine and now it just read lean, even when driving. Any updates on what caused it to do this on your end?
It was the sensor, I ended up buying a generic sensor off of amazon and using the Pig tail from AEMs sensor, spliced them together and its worked great ever since. I know the frustration though of getting one and it not working though 🙃
Same issues here. Bought mine few months back and finally put it on today. Had issues and immediately found this video. 🤦♂️ Such a shame they can’t put a decent sensor in. It would be better if they had made the price cheaper and said get your own sensor. Great video tho, I feel your pain.
3 years later, but just found this video and subscribing cause i feel your pain on this one.. Trying to chase down my stuck on 14.7 issue. Assuming bad sensor. Unfortunately it came with the car so I can't just call AEM for replacements
@@Smeedia wait so the bosch sensor works with the aem gauge? i just got replacement sensor from AEM and still having the same issues. when i put i. the new sensor it was working perfectly fine until 5 minutes later after install it’s goes “- - -“ it’s getting really annoying
Hey man, I’m just curious if you’re her figured out the issue. I just installed same wideband and idled then drove for 10 minutes working normal then all sudden went to 3 dashes. Works for a few seconds on start up then goes back to the 3 dashes. I’m assuming o2 sensor bad?
Literally same deal here! On my 3rd replacement and mine just pegs out lean or ---. Really annoyed at the fact that they as well didn't send a new sensor in my replacement kits. Im ditching them for sure and getting a full refund on mine. I had one that worked for a year straight and thats all ive got to say about aem. I might go with innovative motorsport.
@@Smeedia I'm tempted to just pick one up at a local parts store to see if it reads. I have a turbo build ive been waiting weeks on a wideband for to do some street tuning. I find it very weird that all 3 of my "known good" sensors are just not working at all. I'm gonna run around town tomorrow and find a relatively cheap lsu 4.9 wideband sensor and make sure it comes with a warranty. I wish there was a physical inspection test you could do on a wideband to see if its bad internally. All 3 of my sensors also failed a "sniff" or rag test. I find it hard to believe all 3 are bad
My AEM 30-4110 worked for 30 sec the first time. Summit sent me a new sensor and then it worked for 10 min before showing lean like the first time 🙄. Triple checked supply and ground. JUNK!
Thanks for the help. My 04 WRX had the same issue and I was clueless on the fix. Did the same stuff you did. But I thought I was just fudging something up. Ordered the same part hopefully that will work. Love the videos!!👍🏼
Ended up swapping to a Amazon O2 sensor. Even today AEMs sensors are still poop. Last time I talked with them they said they had a revised sensor in the works. IMO it's not worth sending the unit back. You'll get another sensor that will kill itself. And 5 pin Lamda 4.9 LSU Sensor off Amazon should work
I called them and told them I put new sensor in new gauge in still don’t work they were insisting that it’s the gauge and to send it back to them and by a new gauge and harness
Best colution I've found is to snag a replacement sensor off of Amazon, have had this happen on 3 diffrent cars and the Amazon sensors have yet to fail me after 3 years of use
what the hell is wrong with AEM if this is a consistent problem..I just got one installed on my bike and its doing the same exact thing..Im going to write to company about getting a replacement sensor and take it from there.
I bought a brand new one, tested it out before install it worked. Installed it all, now it flickers once before turning it on and that's it... power and ground are good
Try messing with the connector on the gauge(the one that connects to the o2 sensor) and see if numbers pops ups. If it pops up the connector to the gauge is shitty. Mines was the same way till I kept messing with it till it showed numbers. If it doesn’t read right after that then it’s the sensor.
Glowshift black series 7 is good not e85 supported though... Innovative or Apexi or Apex then... I have a x series and its good for me... Really sensitive on the numbers but its weird that your going through that... Just a thougt if you have a no cats run the ls9 sensor on the rear passenger o2 and delete it just the bk rear... Worked on my mustang but on subi not sure hate the bung weld crap and its just a thought if you haven't tried it... Good luck on that subi sounds good.. If you do the delete have the rear passenger o2 turned off or check light will be tossed on... Just clear the code or codes and turn just that one off.. Again maybe where the location of the ls9 is at? Hope it works....
The link to the gauge should be in the description, but it was the sensor, ended up having to buy one off of Amazon and splice the pigtail from AEM sensor onto it to get one working
Arnaldo Graceski you can calibrate it like you said or aem has pre tuned it from their factory ready to go its either way... They make it have a calibration test if you have issues with it or if its dirty and you re clean it and the gauge is not showing the numbers accurately etc...
The problem is maybe the sensor location. I've got inovate AFR Gauge and the sensor right back after the turbo (Invidia Cat'ed downpipe). I've already replace 3 sensors. I install a switch to power the gauge and heat sink bung but i still have issues with the sensors. I was thinking of change for a AEM afr kit but i see you've got the same issues. (Sorry for my bad english i'm french)
I have used Inovate afr gauges on other cars without any issues but my sensors was more far from the turbo. What downpipe are you using? Are you still catted?
The STI was catted at the time of this video, had the exact same issue with a brand new gauge on my BRZ and the sensor was farther back. Ive heard of people installing switches to them with mixed results. And no worries at all!
I posted as Goldie to explain the setup I used if anyone does the o2 idea you will have to tune it everytime the engine light comes on with a tuner or just weld the bung 18"in from the cylinder head but, you might have pinched or kinked the harnesses that might be messing with it or a bad sensor then....
My issue ended up being the sensors that AEM kept sending me, eventually ended up just buying a sensor in Amazon and splicing the harness to the new sensor to make it work lol
Smeedia do you have a video or wiring diagram which color Aem sensor wire splices to the new sensor you got from Amazon have a replacement coming but not confident on the replacement either,thanks
Did you make a video splicing the sensor to the AEM gauge? I'm experiencing the same issues and want to try what you did but I can't seem to find a video. I just want to be able to splice the two together correctly! Thanks for any input!
When it stays 14.7 no matter what means the sensor isn't connecting btw. Innovate is cheaper and way better, it has error codes and you can actually cal
innovate is as big a POS as the AEM, I have an innovate and its been garbage out of the box, multiple sensors etc, still junk, STAY AWAY FROM INNOVATE! Look online there are pages of complaints, count yourself as one of the few lucky ones,
@@WolfHausMotorwerks you probably did something wrong or bought it from some kid named Eric... Just by looking at your channel you don't seem to be a tuner so you're experience in tuning probably isn't any good
They shoudlent go out in the first week of using them, have had multiple sensors from AEM do this, always replaced with $30 Amazon Bosch sensors that have worked for 2+ years
My original Bosch sensor worked for about 8 months before it started reading incorrectly and not reading at all. I replaced it with an Amazon equivalent which worked for about 3 weeks but started doing the same as the old one then one day it repeated the heat cycle multiple times completely. My sensors about 24 inches from my turbo at about a 9 o'clock angle.
My boost gauge is flat lined tried different fuses. The connections are good and it is sharing power to the afr gauge...idk about aem I really wanted to stick with aem since I want everything to be the same... pretty pissed haha
Hahaha, this is funny.............I had an Innovate AFR gauge, it worked for 9 months. Warranty had run out so I just bought the AEM unit without a sensor knowing the sensors are the same for both. Guess I was wrong. Gauge goes to full lean when you turn it on, which means no sensor is connected. Different sensors......Edit... no no no, I just put a lighter to the sensor and it works. The problem I had was there was a bung extension and the sensor wasn't reading.
@@chuckheinch mine has done the same thing, worked perfect for like 10 min, then 3 dash, hondata says its pushing 3.9 volts entire time. weird thing about mine is that it starts at 14.7 while warming up im assuming then it actually ticks through all the numbers nearly to 3 dashes. my bung was the same the entire time so I dont think its the bung or it wouldnt have worked perfect for 10 min imo
I'm having the same problem with mine. Two consecutive sensors lasted 10 seconds before the went bad. Same shit, 14.7 and then all dashes seconds after start up. Going with another company besides AEM. Their sensors are junk! When they still used Bosch Sensors they were great. Now its Chinese Junk DOA sensors.
@@Smeedia Why did you have to splice the wires? It looks like the sensor should plug right up - The Amazon add says it's supposed to fit the AEM. Each 4.9 sensor has a calibration resistor built into it's connector, so the connector that comes on the sensor not supposed to be eliminated. Just trying to understand where you spliced things??
Mine just goes from 14.7 then goes alllll the way to 18 then those three lines.... and does not move... been doing this for 2 days..... but idk maybe i’m running way too lean.
@@Smeedia Yeah just did more research but thanks for responding ive been freaking out 😂, would you think a ProSport Bosch wideband fit an AEM female connector?

LMAO yo i dont mean to laugh but IM GOING THRU THE SAME SHIT, and.. my gauge did the sAME SHIT. like itll start at 14.6-7 and then BOOM - - - and then u rev it, itll go down like it works, and u let it idle, 18.2-3-4 and then - - - again lol. I cant lie tho my sensor is old, 2 years old. But i jus wanted to know what was the issue from u guys side and now ima jus buy a sensor.

Good information to add! Thank you for adding this and hope that others see this if they're having similar issues

I feel your pain, I have the same issues with a grams performance A/F gauge. I believe it might be a bad sensor, was working fine and now it just read lean, even when driving. Any updates on what caused it to do this on your end?
It was the sensor, I ended up buying a generic sensor off of amazon and using the Pig tail from AEMs sensor, spliced them together and its worked great ever since. I know the frustration though of getting one and it not working though 🙃
Smeedia would you have a link for that sensor?
This is the part number for the one I used

@@Smeedia Thanks
Same issues here. Bought mine few months back and finally put it on today. Had issues and immediately found this video. 🤦♂️ Such a shame they can’t put a decent sensor in.
It would be better if they had made the price cheaper and said get your own sensor. Great video tho, I feel your pain.
Installed one in a customer's car today and had the smar issue as well, the Bosch sensors on Amazon have been the best bet for replacements I've found
3 years later, but just found this video and subscribing cause i feel your pain on this one.. Trying to chase down my stuck on 14.7 issue. Assuming bad sensor. Unfortunately it came with the car so I can't just call AEM for replacements
Amazon Bosch sensors have been a solid replacment, they're like $50 or ao and last wayyyy longer than any AEM supplied one I've had 🫡
@@Smeedia sweet, thanks for the info I'll check it out. Hopefully resolves the issue.
@@Smeedia wait so the bosch sensor works with the aem gauge? i just got replacement sensor from AEM and still having the same issues. when i put i. the new sensor it was working perfectly fine until 5 minutes later after install it’s goes “- - -“ it’s getting really annoying
@@izaiahmartinez9311same thing happened to me but with the Bosch sensor.... it think it's the AEM wiring tbh.....
Gloves? For electrical?
Hey man, I’m just curious if you’re her figured out the issue. I just installed same wideband and idled then drove for 10 minutes working normal then all sudden went to 3 dashes. Works for a few seconds on start up then goes back to the 3 dashes. I’m assuming o2 sensor bad?
Its thr O2 sensor, one one of my more recent videos with my BRZ i had the exact same issue
Smeedia sweet, thanks for the reply man. Hopefully they replace mine as it only ran for 10 mins
Same thing happened, 10 min and the sensor died 🙃
Smeedia gotta love aem
Thwyre going to make you send the whole gauge back to which is the annoying part. 🙃
Literally same deal here! On my 3rd replacement and mine just pegs out lean or ---. Really annoyed at the fact that they as well didn't send a new sensor in my replacement kits. Im ditching them for sure and getting a full refund on mine. I had one that worked for a year straight and thats all ive got to say about aem. I might go with innovative motorsport.
Been using this sensor with my AEM gauge now and going on 2+ years, idk wtf AEM is doing with their provided sensors

@@Smeedia I'm tempted to just pick one up at a local parts store to see if it reads. I have a turbo build ive been waiting weeks on a wideband for to do some street tuning. I find it very weird that all 3 of my "known good" sensors are just not working at all. I'm gonna run around town tomorrow and find a relatively cheap lsu 4.9 wideband sensor and make sure it comes with a warranty. I wish there was a physical inspection test you could do on a wideband to see if its bad internally. All 3 of my sensors also failed a "sniff" or rag test. I find it hard to believe all 3 are bad
Mine did this when I bought it brand new so they sent me a whole replacement setup as well and I swapped the sensor and it started to read.
Seems like it happens to more people than it should 😖
Thanks. Having the exact same issue as the end of the video where it just reads --- after the initial sweep. Going to contact AEM for a new sensor
I’m having the exact same issue right now so annoying
@@julianrosales7121 you can do the rag and spray method to see if it reads rich.
@@justin________7477 im having the exact same problem anyone figure out how to fix it?
GloShift worked really well for me!
Newb question here. Why would you run a AFR gauge, doesnt the AP give you that information already?
The accessport reads upstream AFR off of the header compared to the downstream on the downpipe
@Smeedia I'm learning still but isn't it also becausethe aem uego is a wideband and the stock is narrow band?
My AEM 30-4110 worked for 30 sec the first time. Summit sent me a new sensor and then it worked for 10 min before showing lean like the first time 🙄. Triple checked supply and ground. JUNK!
Snag a Bosch sensor fromAmazon! That'd what I did and been running strong for 2 years!
Thanks for the help. My 04 WRX had the same issue and I was clueless on the fix.
Did the same stuff you did. But I thought I was just fudging something up.
Ordered the same part hopefully that will work.
Love the videos!!👍🏼
Let me know how it works! 🙏😁
I’m going through this right now did you ever resolve this his problem or did you just get a hole new unit
Ended up swapping to a Amazon O2 sensor. Even today AEMs sensors are still poop. Last time I talked with them they said they had a revised sensor in the works. IMO it's not worth sending the unit back. You'll get another sensor that will kill itself.
And 5 pin Lamda 4.9 LSU Sensor off Amazon should work
I called them and told them I put new sensor in new gauge in still don’t work they were insisting that it’s the gauge and to send it back to them and by a new gauge and harness
Mines reading exactly like yours. What did you come up with?
Swap the sensor 🙏 replaced mine with one off of Amazon
@@Smeedia thanks buddy. I just got mines on Amazon and trying it right now.
@@Smeedia WHICH ONE DID YOU BUY FROM AMAZON?
FOUND IT IN THE COMMENTS
Had mine for 3 years no issues
Just installed mine first day was working fine for a day and stays stuck on 14.5
Can bad fuel be the source too for not reading it? All I get is 3 dotted lines but my AP says otherwise.
9/10 times it's thr sensor bad fuel wouldent cause it to read 3 lines
mine is doing it now, did you get any results? stays on full lean.
Ended up swapping to this and been going strong for 3 years 💪

Have you did a calibration
@@Smeedia is it possible to use the amazon sensor with the aem gauge? I dont want to have to redo my wiring
Yessir, that's what I use. Been going strong for 2+ years

what the hell is wrong with AEM if this is a consistent problem..I just got one installed on my bike and its doing the same exact thing..Im going to write to company about getting a replacement sensor and take it from there.
I figured it out on mode keep Clicking till it says recal and click sel and then switch back to afr do it few times and Boom 💥💪🏻 Hope it helps u all
What if ours have no damn buttons on the gauge ? LMFAO
@@poohnay16then we’re fucked
Did you try and run calibration settings
I have a problem also , always worked and now it works couple of seconds and than it goes to three dashes ? Any help...
Sensor is bad, 🙃 had the same issue with 3 sensors
I bought a brand new one, tested it out before install it worked. Installed it all, now it flickers once before turning it on and that's it... power and ground are good
Make sure the electrical connectors are fully seated on the backside
Did you end up finding the issue? I have a brand new aem afr then was good then - - - :(
Bad AFR sensor out of the box 😭 ended up getting a replacement off of Amazon
@@Smeedia Forsure bro thank you 🙏🏻
At least yours shows numbers. Mine just shows three dots and I cannot figure it out.
It’s the sensor, I had the same issue. Took me 3 sensors till it worked correctly.
Try messing with the connector on the gauge(the one that connects to the o2 sensor) and see if numbers pops ups. If it pops up the connector to the gauge is shitty. Mines was the same way till I kept messing with it till it showed numbers. If it doesn’t read right after that then it’s the sensor.
Aem recommended Bosch 17025 as a replacement, bought mines from O’Reilly auto with free 1 year warranty.
On start-up mine will only say "test". No numbers. nothing else.
Glowshift black series 7 is good not e85 supported though... Innovative or Apexi or Apex then... I have a x series and its good for me... Really sensitive on the numbers but its weird that your going through that... Just a thougt if you have a no cats run the ls9 sensor on the rear passenger o2 and delete it just the bk rear... Worked on my mustang but on subi not sure hate the bung weld crap and its just a thought if you haven't tried it... Good luck on that subi sounds good.. If you do the delete have the rear passenger o2 turned off or check light will be tossed on... Just clear the code or codes and turn just that one off.. Again maybe where the location of the ls9 is at? Hope it works....
Wtf r u even talking about
Did you figure it out the problem? What’s the part number of the AEM?
The link to the gauge should be in the description, but it was the sensor, ended up having to buy one off of Amazon and splice the pigtail from AEM sensor onto it to get one working

Would you try the pro sport gauges? This video making me scared of getting aem ones lol
It was just the sensor and ive never used prosport before so I'd have to read some reviews
Yeah they are pretty fool proof just run a good Bosch wideband 02
i never have problem with PLX ones i change to AEM on my rex and the problems start
I just picked up a 30-4110, the car is stuck on LEAN
Happened to me as well. Was a bad sensor
😂I need to try the yelling tapping and flicking, mines doing the same exact thing.
It worked momentarily 😅😅😅
T was the sensor the entire time. Bosch sensors are junk
Is there any replacements for it besides Bosch?
Hey man , my boost gaige just stays in " sens" and i bought another sensor and it still says " sens " what could it be ??
At that point I'd contact AEM whenever I see that it's normally a gauge issue
@@Smeedia thanks man , im always learning things in your channel , keep it up 🤙
My afr eam worked only a week and stuck on 10.6
I thought that when using a new gauge you had to leave the sensor out, let it cycle, then install it
Arnaldo Graceski you can calibrate it like you said or aem has pre tuned it from their factory ready to go its either way... They make it have a calibration test if you have issues with it or if its dirty and you re clean it and the gauge is not showing the numbers accurately etc...
@@goldieberry9693 you can't cal the aem uego, it is what it is
The problem is maybe the sensor location. I've got inovate AFR Gauge and the sensor right back after the turbo (Invidia Cat'ed downpipe). I've already replace 3 sensors. I install a switch to power the gauge and heat sink bung but i still have issues with the sensors. I was thinking of change for a AEM afr kit but i see you've got the same issues. (Sorry for my bad english i'm french)
I have used Inovate afr gauges on other cars without any issues but my sensors was more far from the turbo.
What downpipe are you using? Are you still catted?
The STI was catted at the time of this video, had the exact same issue with a brand new gauge on my BRZ and the sensor was farther back. Ive heard of people installing switches to them with mixed results. And no worries at all!
@@Smeedia Brz Catted also?
Catless on the BRZ
@@Smeedia the sensor you've used on the BRZ was a brand new sensor too?
My AFR reads 8.08 for roughly 15 minutes after initial start up, reads correctly for about 10 minutes then goes back to 8.08 😅
I posted as Goldie to explain the setup I used if anyone does the o2 idea you will have to tune it everytime the engine light comes on with a tuner or just weld the bung 18"in from the cylinder head but, you might have pinched or kinked the harnesses that might be messing with it or a bad sensor then....
My issue ended up being the sensors that AEM kept sending me, eventually ended up just buying a sensor in Amazon and splicing the harness to the new sensor to make it work lol
Smeedia do you have the wiring diagram for splicing
Smeedia do you have a video or wiring diagram which color Aem sensor wire splices to the new sensor you got from Amazon have a replacement coming but not confident on the replacement either,thanks
I dont 😪 i need to make another sensor though for the STI so ill make a video on it
Did you make a video splicing the sensor to the AEM gauge? I'm experiencing the same issues and want to try what you did but I can't seem to find a video. I just want to be able to splice the two together correctly! Thanks for any input!
I’m having the same exact problem with my AEM sensor I installed a couple weeks ago. Pegged out to lean
Bad sensor. Annoying problem but an easy fix
When it stays 14.7 no matter what means the sensor isn't connecting btw. Innovate is cheaper and way better, it has error codes and you can actually cal
Good to know, AEMs customer support was pretty quick to fix the error but still had to go through 4 sensors lmao
@@Smeedia ouch, yeah I've had innovate for like 5 years and only had to change sensors, buy one from oriellys with a lifetime warranty lol
innovate is as big a POS as the AEM, I have an innovate and its been garbage out of the box, multiple sensors etc, still junk, STAY AWAY FROM INNOVATE! Look online there are pages of complaints, count yourself as one of the few lucky ones,
@@WolfHausMotorwerks you probably did something wrong or bought it from some kid named Eric... Just by looking at your channel you don't seem to be a tuner so you're experience in tuning probably isn't any good
When I had innovative afr I went through 2 o2 sensors so I just switched aem afr x-series. I hope it doesn't fail.
Has nothing to do with AEM bro sensors go out on all wide bands its normal if you have it long enough or if you go e85.
They shoudlent go out in the first week of using them, have had multiple sensors from AEM do this, always replaced with $30 Amazon Bosch sensors that have worked for 2+ years
@@Smeedia i use bosh lol they are good but even then we kill them on the dyno
Yup just one of the many commenter here.. installed worked for 3 days than permanent lean when car runs but brake clean and a rag reads full rich
I've had pretty good success with Bosch replacements on Amazon.
You need to stop listening to me work.. telling the gauge "I hate you" ? LOL
Mine does the same thing. New install can't get it to work.
Those AEM Sensors seem to just have some quality issued out the box
Just the sensor everytime, probably to close to the turbo or placed wrong, I've done about 4 sensors in 6 years bosch lsu 4.9
My original Bosch sensor worked for about 8 months before it started reading incorrectly and not reading at all. I replaced it with an Amazon equivalent which worked for about 3 weeks but started doing the same as the old one then one day it repeated the heat cycle multiple times completely. My sensors about 24 inches from my turbo at about a 9 o'clock angle.
My boost gauge is flat lined tried different fuses. The connections are good and it is sharing power to the afr gauge...idk about aem I really wanted to stick with aem since I want everything to be the same... pretty pissed haha
Had the same issue with my last car it's the sensor 100% really annoying to have to deal with. They make you send the entire gauge back to them 🙃
Smeedia it really sucks bro paying all that money and have problems... but when it works out the feels is almost unbeatable lol
Hahaha, this is funny.............I had an Innovate AFR gauge, it worked for 9 months. Warranty had run out so I just bought the AEM unit without a sensor knowing the sensors are the same for both. Guess I was wrong. Gauge goes to full lean when you turn it on, which means no sensor is connected. Different sensors......Edit... no no no, I just put a lighter to the sensor and it works. The problem I had was there was a bung extension and the sensor wasn't reading.
Meaning the sensor wasn't deep enough? I may grind my bung down. I had to weld it
@@chuckheinch mine has done the same thing, worked perfect for like 10 min, then 3 dash, hondata says its pushing 3.9 volts entire time. weird thing about mine is that it starts at 14.7 while warming up im assuming then it actually ticks through all the numbers nearly to 3 dashes. my bung was the same the entire time so I dont think its the bung or it wouldnt have worked perfect for 10 min imo

I'm having the same problem with mine. Two consecutive sensors lasted 10 seconds before the went bad. Same shit, 14.7 and then all dashes seconds after start up.

So can you point me in right sensor direction
amzn.to/3u9yQfA
@@Smeedia Why did you have to splice the wires? It looks like the sensor should plug right up - The Amazon add says it's supposed to fit the AEM. Each 4.9 sensor has a calibration resistor built into it's connector, so the connector that comes on the sensor not supposed to be eliminated. Just trying to understand where you spliced things??
Swapped pigtails because they were not same same, at least the one I got was not same same
def has to be the sensor.
No conclusion. Don't need to watch video thru🤙
