Awesome Im glad I could help. You do NOT need internet for the ktuner to work. Only time you would need internet is if you need to do an update to the ktuner unit.
So I have a ktunerv2 but it don’t have the code p0420 in the options to erase the code.keep getting check engine light since I stnalled the down pipe you have any idea bro?
I have a 21 Type S with IMR catted downpipe plus secondary is catted as well, I also have K tuner but just recently the check engine light came on for code p2270 which has to do with the sensor on the cat, now unfortunately the k tuner only comes with stage 1 tune for my car because I was doing my representative that the ECU for this car is a bit complicated so I can't change any parameters in the car as of now so I can't disable O2 sensor
It disables it okay. BUT would the CEL come back on in the future if I have other engine problems? or does it completely remove it and it never comes back on?
This only disables it for the O2 sensor on the down pipe. So YES If another sensor or anything else goes bad with the engine, the CEL light will turn on.
I just disabled the cel and the code still came on this morning only drove for about 15 minutes after hoping it was a one time thing that corrects itself car still ran great.
@@mikeeyyyy9681 no my dumbass left the light on killing the battery, I thought I reset it but it's still pulling more then stock boost. Jumped the battery working fine now
When you put you cat less down pipe and front pipe on did you car ideal a little rough when you first started it up before you had to re flash your car
@@MoisesEmpire Hey buddy update on our car. LOL make sure everything is plunged in that's the reason why my car was idling funny lol. But when we put the PRL catless down pipe on and we got everything figured out we started driving it and that stupid emission light keep popping up on my dash with the Ktuner V2 I kept resetting it on my Ktuner could not figure out what the heck was going on well we did when we got home from a cruise in we thought we disabled everything the first time we did it but when we flashed the car first then disabled it lol ops but we are good know after I watched this video again I went back out like I said hooked it up sure enough the two codes where not checked we have a custom stage 1 tune. So now they are checked saved and uploaded to the ECU. This is our very first time tuning a car by ourselves I never done it before but the way you explained it man 1 click here click here click here boom done so we are golden. So thank you for your video that was so much help.
I’m on tsp stage one and just installed catless dp and fp with IC and charge pipes would I need to reflash after ? Also had this problem so thanks for vid !
I️ got a prl intercooler/charge pipes, act clutch kit, mishi moto oil catch can, and a prl cobra cai and now im getting a uo131 code and I️ can’t find anything online about it do you know why?
Maybe you can help me out. I installed a cattless dp today on my accord 2.0 & totally messed up by forgetting to disconnect the neg battery terminal before disconnecting sensors. Now I have 11 CEL all relating to the sensors I disconnected. Could i clear codes with an obd2 scanner?
Yes that should work. But you might still have a CEL because of the catless down pipe. Unless u have a tuner or I hear that a 90° O2 sensor adapter will also work.
Hey, would I need to reset the car to factory before or after installing the DP, or just change the setting and reflash after I have installed the DP? And did the code come back after driving certain miles?
Just change the setting and reflash after u install the DP. If done correctly then no codes or lights will appear. Im about 10k miles after my install and still no lights on dash.
@@MoisesEmpire awesome thanks! I have to wait till Sunday. I also read that some people disable the slow 02 sensor as well but hopefully I don't have to do it.
@@niharpandit3355 ur welcome! Good luck with the install of the DP. I know the bolts are on there tight but DO NOT use power tools or you will strip and break them. Do it by hand with a breaker bar.
@@MoisesEmpire thanks bro! I actually decided to have this guy install it for me. He works for Honda and he does weekend jobs on the side. So he will charge me 100. I'd rather trust him then my clumsy self haha
@@leoeduarte1173 mine hesitates at full throttle on stage 5 18psi. I have PRL catted downpipe and front pipe. Still waiting on my Invidia Exhuast to come.
I tried to disable it but I get an error saying that the unit is locked to an ecu that doesn't match the one you are trying to flash.. using the same laptop I installed everything on.. can you or anyone help me with this? Am I the only one it happened to? T.I.A.
Yeah u can install tunes on it but if the tuner has ever been used on another car then it wont work on yours unless its been unlocked from said previous car. But if it is new and only ever been on your car, then u might wanna try to unlock it from your car and add it again after. Make sure its plugged into the car properly.
I have the v1.2 they are the same as far as what u can do tuning wise. The good thing about the V2 is that you have the screen which lets u switch tunes without the need for a laptop. You can also monitor things like temperature and boost PSI and if your car is a 6 speed manual then I believe u can setup shift lights so you know when its good to change gears.
I just got the PRL downpipe installed, and I followed your steps, did everything right all the light went away, then when I left the car for about 20 mins and drove somewhere and as I was reversing all of a sudden all the lights came back on. Do you know why it did that?
@@ryani5604 then ur gonna have to do the steps again. It must have not loaded to the car correctly because the catless down pipe should only make the check engine light turn on and nothing else. So if you have multiple lights poping up then something didnt go right when u did the tune.
I have a catless downpipe front pipe I flashed the car clicked the box for catalystic efficiency and within maybe 15 miles of driving the check engine light would come back on I have tried several times to clear this code but at this point i don’t wanna keep re flashing the ecu as I’m sure it’s Probally not good for it what should I do
If your following all my steps exactly (check the box for the cat before you flash the car) then maybe the check engine light is turning on for a different reason.
How was your mpgs after the delete? I've been thinking about doing this to my 9th gen SI with gas prices soaring. I would assume they would skyrocket but at the same time do you need a custom tune to adjust for the delete to see actual gains?
No change in MPG that i could tell. You do not need a tune to see gains but a tune will give u even more gains. A tuning device is more used in this case to get rid of the check engine light like I show in the video.
The light is very annoying for sure. Thanks for the video
Sure is. Your welcome.
Hey thank you for the video this helped a lot.
Ur vids absolutely helps me a lot especially in my research. Just wondering do you need internet for ktuner to work?
Awesome Im glad I could help. You do NOT need internet for the ktuner to work. Only time you would need internet is if you need to do an update to the ktuner unit.
Did you ever have a problem with the check engine light coming back on after this? Idk why my car is doing that
Nope. After this it never came back.
good vid. thanks keep it up
So I have a ktunerv2 but it don’t have the code p0420 in the options to erase the code.keep getting check engine light since I stnalled the down pipe you have any idea bro?
Flash it again doing the steps in mention in this video and it should go away
My engine light is on for p145c and p0457 do u think that can get rid of IT
Its possible because doing this disables the sensor. Like its not there.
I have the k20c2 with the rv6 cat-less downpipe and I disable it and it keeps popping up after a couple of miles
I'm not sure why. It worked for me and light never came back.
Thank goodness for this video bro. Just got my downpipe installed and had no idea how to take the CEL off, until now. Thank you!!!!
Lol your welcome!! Enjoy the new down pipe!!
@@MoisesEmpire if your still responding what about a high flow cat?
@@idkidc3192 this method will also work for that.
will it pass emissions after removing code
Not sure to be honest. I live in Florida and we dont have to worry about emissions here.
Mine popped up still after disabling P0420. Also my ktuner doesn’t show P0299 in the disable monitor section? I have a 2018 civic si
Weird. All I can suggest is that you try and flash the car again. Maybe u missed a step in the process or did something in the wrong order.
@@MoisesEmpire I’ll try doing that again in the day. I’ll update you
I installed a catted high flow down pipe mine keeps popping up every 50 miles
Yeah its sucks when it pops up. Gotta either custom tune the car or just disable the sensor like I show in this video.
I have a 21 Type S with IMR catted downpipe plus secondary is catted as well, I also have K tuner but just recently the check engine light came on for code p2270 which has to do with the sensor on the cat, now unfortunately the k tuner only comes with stage 1 tune for my car because I was doing my representative that the ECU for this car is a bit complicated so I can't change any parameters in the car as of now so I can't disable O2 sensor
Dang thats unfortunate. Try using one of those 90° extensions for the O2 sensor. I never tried one but I hear they help keep the engine light away.
@@MoisesEmpire Actually IMR installed it for me & he
did put a defouler on it but maybe it's just malfunctioning
Did your car pass inspection after doing this? Thanks 👍
I live in Florida and there are No inspections here. So its not something I ever need to worry about.
@@MoisesEmpire word
Thank you my guy
Your welcome
Do you have to retune if you alreadly have a tune or can you edit ?
Technically both. If you want to edit something, you then have to upload that edit to the car which is technically retuning.
It disables it okay. BUT would the CEL come back on in the future if I have other engine problems? or does it completely remove it and it never comes back on?
This only disables it for the O2 sensor on the down pipe.
So YES If another sensor or anything else goes bad with the engine, the CEL light will turn on.
I just disabled the cel and the code still came on this morning only drove for about 15 minutes after hoping it was a one time thing that corrects itself car still ran great.
@@lifeofhardknocks.3280 what engine code was it ?
@@mikeeyyyy9681 no my dumbass left the light on killing the battery, I thought I reset it but it's still pulling more then stock boost. Jumped the battery working fine now
Work on a 15 tlx?
Its should if you have the same option in your tuner device.
Question does it matter if it a Honda hatchback cvt would I be able to use the same steps?
Yeah same steps. Transmission might be different but everything engine related is the same.
Does it matter which type of computer/software to make ktune even possible??🤔 I’m new to all of this
Any windows computer. Apple wont work. U just go to the ktuner website and download the program and follow the steps on the screen.
When you put you cat less down pipe and front pipe on did you car ideal a little rough when you first started it up before you had to re flash your car
Not that I can remember. Only difference i remember was that it was much louder lol.

@@MoisesEmpire thanks buddy we will. Thank you again
I’m on tsp stage one and just installed catless dp and fp with IC and charge pipes would I need to reflash after ? Also had this problem so thanks for vid !
Yes becuase of the catless dp. That requires a reflash.
I️ got a prl intercooler/charge pipes, act clutch kit, mishi moto oil catch can, and a prl cobra cai and now im getting a uo131 code and I️ can’t find anything online about it do you know why?
Where did you get the carbon fiber for the wheel? I can never find the right ones
www.synthcarbon.com/collections/frontpage
Would you pass echeck after disabling it?
Sorry but I don't know what echeck is.
So you can't clear the codes without doing a new tune?
Dont think so. Tuner is not made to clear codes. Its made to make adjustments to the car.
I’ve been living with the CEL for over a year and this video saved me bro
Glad I could help!
Been having for years about to do this 😂
Maybe you can help me out. I installed a cattless dp today on my accord 2.0 & totally messed up by forgetting to disconnect the neg battery terminal before disconnecting sensors. Now I have 11 CEL all relating to the sensors I disconnected. Could i clear codes with an obd2 scanner?
Yes that should work. But you might still have a CEL because of the catless down pipe. Unless u have a tuner or I hear that a 90° O2 sensor adapter will also work.
The downpipe i bought came with a bung for the oem o2 sensor. Do you mean i should weld a different 90 degree bung & take off the one it came with?
Would you know if this work with a 27won downpipe if I followed the same steps
Yes. It will work for any down pipe since your just changing the setting to the sensor and turning it off.
@@MoisesEmpire Thank you so much I appreciate it a lot
So I have a catted MaProformace dp, my emissions came on hours later after install, would I just follow these steps for it to go away?
Yes. These steps will turn off the sensor on the dp so that you dont get any lights on the dash.
Awesome thanks bro
Is it the same thing with catted dp?
Shouldn't need to do anything for a catted dp but yes the same steps will work for catted dp if its needed.
Thank
Will this work for the cvt
Yes. Same steps to do it.
Good 👍 ASS job Brudda ✌.

Let’s say that you need to pass emission inspection will this help you out with that ?
To be honest im not sure. Where I live we don't have emission inspections so I don't have any experience with that.
I believe as long as the CEL is not on you should be good. I just asked my mechanic the same question,
Which k tuner do you have ?
The small one. V1.2
If you dont have prl MAF should it be left at custom? For MAF calibration
Yes just leave it at custom. If its not the prl RACE MAF then you dont need to tune it so just leave the tuning part alone.
Moises Empire thanks, I just flashed my car with k tuner, how safe is it to run that tune on a cvt?
@@leoeduarte1173 from what I hear its perfectly fine. But I have a manual so i cant give u any personal experience.

Did u buy the tuner used? Sounds like the tuner is programmed to another car.
@@MoisesEmpire nah it was brand new and even installed the dual stage tune too
Yeah u can install tunes on it but if the tuner has ever been used on another car then it wont work on yours unless its been unlocked from said previous car.
But if it is new and only ever been on your car, then u might wanna try to unlock it from your car and add it again after. Make sure its plugged into the car properly.

This causes your vehicle to run rich and sluggish when turning it off. Would be better off just leaving it on.
