does anyone out there have a tuned program for a k20a motor(RSX type-R JDM). I have a k20a and i'm having problems with detontation under load.

I was wondering why my car is throwing a "unknown code 77" if i use the jumper off the obd2 plug it say code 41. Its the o2 sensor heater. the o2 sensor heater i believe is controlled by the ecu. is ther a fix to this problem or is it a issue with my k-pro?

I replaced the front o2 sensor today and it still does the same thing "unknown code 77" and if i jump the obd2 service connector its code 41.

My KPro reads "unknown code 77" When I put my motor in I did not cut any part of my harness so it should all be good. I'm going to try to replace my frint o2 sensor. The MIL will still go off even if I turn the o2 sensor heater off from the kpro.

I'm throwing a code 41

I have no cat and I have both O2 sensors plugged in.

obd2 has been disabled and I still get that code

I datalogged the car and it threw a unknown code 77. Do you know what a "unknown code 77" is? That is the code thats been setting off my MIL.


Thanks

If I ...
