Hey everyone, I recently found out my LS swap is not doing so well, and I want to swap a b20 in the car. I am having a hard time finding out what ECU would be best to run the stock b20 in my car.

Heres the setup
1997 honda civic EX coupe
B20B w/ GSR tranny


I am thinking either

P2E : 96+ OBD-2 Civic DX Coupe
or
P75 : 96-00 OBD-2 Integra LS/GS

Im leaning more towards the P75, anyone got any suggestions? Thanks everyone.

 

one thing to consider is you are restricted to only 96-98 ecu's obd2a they are called. Obd2b were in 99-00 and will not plug into your car.

 

Integra ecu. thats what i always use on them.

 

LS ECU. The LS engines are very similar to the B20. You should put a different head on it though, the stock B20 heads are crap.

 

agreed...the b20 head flows like the LS head, which is shitty.....put a vtec head on that mofo....i loved it when i had mine...

 

LS ECU. Just make sure you are using a 96-98 ECU (OBD2a) as mentioned above.
