idk if youll see this or not, but i installed my wideband already (really huge rebuild whole car is in pieces p much lol) and i put the wideband O2 where the post cat O2 was. i have a resonated test pipe (no cat). should i move the O2 to this pre cat position or can i leave in where it is under the driver seat basiclaly? thanks lol
@@kaoriisdriving Most people I know run the wideband pre-cat but I would consult the manual included with your wideband to determine if it's okay to run post-cat
Been fighting my 04 msm for like 2 weeks after rebuilding it and putting some 700cc injectors in it. I still have a lot of work to do with the tune but I finally got it to fire up and run on its own for a bit. I plan to work on it more when I get home from work and people wake up in the neighborhood. Hopefully it sees its first road trip in 4 years later today! Good video, would be great to go into more detail on some of the settings once you start getting it dialed in.
I'm about to swap the ECU on my NA and this video helped answer several questions I had about which sensors are needed w/ the MS and how to get the initial setup done. Thanks, and keep the great content coming.
Hi Shawn, thank you! - I turbo'd the car and am in the process of getting the tune really dialed in. I will make a more advanced video once I have it running 100%. There are definitely some interesting things to cover
Any idea why my idle is hunting with the a/c on? I have the tune set up pretty good but at idle a/c won’t blow cold and the idle rises and falls when the comp kicks on. But driving it blows cold.
Is there any reason you did not utilize the CAN function of the AEM wideband? My ecu is coming Monday and I’m at crossroads on deciding which way to go
I prefer working with signals that I can measure with a voltmeter when possible. I don't know enough about the CAN bus signal type to be comfortable using it. If it was required, I would use it. But otherwise I'll stick to the tried and true DC voltage. Let me know if you try the CAN out though!
@@EnigmaEngineering I think I’m going to try to use the can, my hope is with the faster response it can possible improve drivability, which is very important it to me being that it is a daily driver. Only downside is that if I want to add another can device that is not AEMnet, such as canchecked, I will have to get a different can wideband or use regular 0-5v.
@@jacksonhamblin5242so I can’t use a aem Wideband with a canchecked gauge? can I use a innovative wideband with a canchecked gauge? From what I read I believe they use the same can bus protocol?
Thanks for this very comprehensive video! I am about to begin a Track Dog Racing Rotrex Supercharger installation and will be using the MS3 for my 2002 Miata. One question I have for you is why you chose to wire your AEM AFR Gauge to the factory Harness and not directly from Gauge to MS3? Is this mandatory or just an option. I have the Innovate PSB-1 Boost/AFR gauge and Racing Beat Header with Wideband O2 Sensor bung. I am seeing others who wire directly to MS3 Accessary port with one wire from the gauge for signal and just leave the stock upstream O2 sensor installed and connected. I am guessing you do not have a midstream bung welded into your exhaust and are using the factory headers bung to run your wideband setup. What am I missing here. And thanks for any response!
Hi Tony! There might be some way of wiring it similar to the way you suggest, but I just followed AEM's manual and recommended install method. I am a bit apprehensive about sending and receiving extra accessory signals with controllers like the ms3 unless these signals are 100% essential, because an electrical short or blown fuse could take out the whole ECU in a second. This is why I re-used those ECU wires. You are correct - I removed my midstream o2 sensor and am just running the one closer to the headers (the wideband here), then re-using the OEM wires into the harness for less of a wire mess. Hope this helps. Good luck with your supercharger!
It should be heated up in less than 2 minutes. One way to test this is to order a cheap variable DC voltage power supply off amazon and just test it out of the car. I test all my gauges like this before I install them
This is probably the most visualy compreensive video on the subject. Nice to finally see one on the nb! Did you have any problems with your alternator regulation?
Thank you Guillaume! I did not have any problems with voltage regulation until the other day. But, I think it is my fault (traveling so can't verify). The alternator settings in tunerstudio pull regulation voltage over a throttle position of 101% for additional power (you can change this). So, it will run rock solid at 14V, then suddenly drop if you exceed 101% TPS. My data is showing 0 to 102.5% TPS. I just need to rescale my pedal and hopefully it fixes it. Or bump up that alternator % setting. Hope this helps
I watched this video probably 15 times while installing my ms3 and hooking up my wideband. Cannot thank you enough!

@@calebsnider3490 so I checked around- it is okay to run a “post cat” wideband as long as the cat has been deleted
This is the most helpful video I have found to install and wire a wideband into Megasquirt. Thank you!
No problem. Thank you for the compliment alexis!

Thank you for the compliment John. I am glad you found some useful info here. Good luck with your NA!
Thanks for the video! I'm getting ready to megasquirt my '00 NB, and this made it a lot less intimidating
No problem Dan. Thanks for the note. I hope this helps!
Subscribed, appreciate the well documented and detailed process for this! Are you planning a more detailed video of tuner studio/features of the MS3?

@@EnigmaEngineering Sounds great, looking forward to it! Would also love to see more 4th Gen 4Runner videos too!
Super helpful video!
Do you have the link for the O2 sensor extender?
Thank you for this video.
Nice! Will be installing my mspnp2 soon.. after having it for nearly a year in the box 😭
Get after it! Mine was sitting for longer lol
Can I use the stock air temp sensor?
Will my mega squirt 3 fix my Base 2005 Miata’s charging system overcharging my alternator and battery?
Does anyone know if you unplug the MAF and just run the wideband ? or if u still need the maf after you've installed everything?
Any idea why my idle is hunting with the a/c on? I have the tune set up pretty good but at idle a/c won’t blow cold and the idle rises and falls when the comp kicks on. But driving it blows cold.
Very nice video, will help with my 99 instal.
Thanks
What did you set your spark mode to under “ Ignition Options “ I’m having an issue there.
in the ego ports i dont see o2 in, I see normal ego, analong in 1, analog in 2, analog in 3, and can ego
Also my map(Kpa/psi gaugecluster) for some weird reason is showing on tunerstudio like its red
Random question, I have the same Sparco steering wheel, however my horn button keeps falling out. Hope does yours stay in

So did you have to splice the signal and ground wire to the ebay harness?
Why would you need a gm air temp sensor if you already have a Mazda one?
The GM supposedly reacts faster to temperature changes! Great to have with a turbocharged car
I'm guessing you had both factory o2 sensors and the Wideband was a 3rd? because i saw no check engine light
How do you get that display on your laptop? I think its Awesome but dont know how to get it.
Thanks! DB9 usb to serial cable, then tunerstudio software. You might need to install a driver for the cable. It plugs into the back of the megasquirt

How long did the AFR gauge take to heat up for you the first time? Mine has been stuck saying heat for a long time, probably waited 5-10 minutes.
It should be heated up in less than 2 minutes. One way to test this is to order a cheap variable DC voltage power supply off amazon and just test it out of the car. I test all my gauges like this before I install them
Fueltech or Megasquirt ?.
Did you keep the MAF sensor installed or remove it later on? Thanks
lmk if u got it figured out currently trying to setup my 2000 nb1 on ms3pro

I hope this isn’t a dumb question but once you find a good 12 volt supply for your wide band how do you go about using that 12 volt source ?
I would use that 12v power supply and hook it up to a relay. This basically turns your 1 12v source into multiple sources
This video is from Jesus Christ himself thank you so much lmao
