So we picked up an obd2b integra auto. Swapped it into an obd2a ek chassis. Rear mount modified,crv water pump mount,crv ac compressor mount, integra front right lower,and crv auto right upper. It runs on the stock p2p(vtec) ecu but bounces off.the limiter before it.shifts. We tryed a crv auto.ecu,i guess shiftong.is.different. One would think an obd2a integra ecu will solve all lofe problems.but its only a 3 plug i need a 4. Where.do.i.go from here. Bear with me on the apelling situation. Cell phone sucks!

 

Then you don't have it done.
Get an adapter harness for the ECU.

 

We modified the obd2a existing harness, we are running.an obd2b teg dizzy with od2a d series.harness is that an issue. Car runs good just shifts are fucked up. What option do I have.

 

Modified how? If you leave details like this out you'll be SOL trying to figure this out.

 

I have seen this posted a couple times since Ive joined on here, the way they got it working is using a jumper harness and running obd1 p75 along the TCM. A quick seach on here i see a guy state he sells the harness to get this running right, his screen name is Blown90hatcH

 

I am die hard honda fan and I never knew a tcm existed lol. I rewired the ckf sensor,iab,iacv,etc... I just need a pinout or schematic on wiring a tcm in. so a auto obd2a p75 is no good to me?

 

How do I wire a 3 plug obd2a integra auto ecu into a 96 98 obd2a ek chassis. Where is the tcm too? I need help its my parents car I done this for and I want to get them to the good side never mind d series auto !

 

Cmon bys, can i use a obd2b ecu which has tcm built in and just remove imm and cel bulb
