start up kmanager go to paramaters click on misc. and disable the obd2 sensor. this feature will disable your 02 sensor that you are not using right now because of the removal of the cat.

no the car should be off. this is what you do: stick your key in the ignition and turn the key to the second click. if yoyu just turn the key a little bit you will hear one click but if you turn your key a little bit more you'll hear the second click. now leave it in theat position and then upload y...

You are combining a few completely separate issues and assuming they are all the same thing. This is not the case and we are only looking at the original issue which was posted of getting error P0420 while OBD2 is disabled. YEAH THAT'S WHAT I'VE BEEN WAITING FOR. THAT'S WHAT THIS TOPIC WAS ABOUT OR...

???

I also have the same problem. I keep getting the code error P0420.? I also have the OBD2 disabled and it keeps coming on. I know it's detecting that I dont have a cat but it annoys the hell out of me.

COOL I will do that this weekend thanks

I'm running that same calibration (k20a3 civic high octane) but why didn't I feel much if a HP gain. I heard that just by simply connecting the kpro ecu back on the car you can feel a huge gain already, and that's before the dyno tune. I still haven't dyno tuned my car yet should I have to dyno tune...

I have the k20A3 w/KPRO and I want my VTEC to kick in where it used to kick in when it was stock ecu. Now I know that my lower boundary is set to 2200 rpm but where is my upper boundary set to? I don't want my engine to die on me because I changed my vtec point to 4500 so I rather go back to stock V...
