So is there 2 types of p75 ecu's, one thats obd1 and obd2. Cause I have a b18a1 that came out of a 92 integra ls. So apparently the ecu is for the b1's is this ok that im running a b1's ecu for an a1?? Any differences? Is there a way the ecu could be obd2 and there converted it somehow?

 

The ECU doesn't care if the motor is OBD1, OBD2, a rotary, a jet, or a turkey and cheese sandwich. As long as all the sensors respond and react properly, it's happy to run it.

Listing what type of car you have helps.

Edit: IIRC, B1's are OBD1

 

What's your question exactly? Do you want to know what ecu to use? Yes, you can run a B18B ecu(p75) on a B18A (pr4 I believe). Just use the correct ecu for that chassis

 

What you mean correct edu for chassis. Im using p75 in a civic for a b18a1.

 

I was unaware that the civic was only made for one year and in one model.

 

LOL, like pulling teeth, or maybe the year of the car is secret.

Also would help if we know MM&Y of car engine was out of, was it auto or 5 speed, is the civic auto or 5 speed.

OP, You can't give too much info on car and car engine is out of, every little bit helps. 94

 

Hey I know I'm bringing a dead thread back but its fitting so I have a b18a1 with an automatic trans I'm not manual swapping yet but I would like to run a p75 for chipping later and manual swapping but. Since I plan on running the obd1 p75 am I ok running everything I got from my da9 tcm too or will that not work
