Well that's it, i have a 1994 JDM b16a in my 1990 integra converted to OBD1....

I had a B18c1 in the car and everything was fine, so the convertion to OBD1 is succesfull.... i recently dropped a valve so i had to change the motor for the second gen b16a....

Here's the problem,

During hard acceleration, let's say at 90% of the gas pedal, the engine accelerate then vtec kicks in at 5700 ( i ajusted the VAFC for the vtec to kick in at 5700 instead of 5600 as the ECU want it to do ) The car bog like it lacks ignition during 1/2 second, then it goes again, then cut again, and finaly reach 8000 rpm....

One strange thing is that when it bogs like that, the shiftlite glow at the same time the engine bogs..... beside that everything is fine. Vtec seems to engage properly.

The only code the ECU is throwing is code 14 and 20 which are IACV and Electronic load detector.... which i think don't have a link with my problem.....


Thanks in advance for any help, it will surely be appreciated
