Hey I've got a 93 auto integra, and I'm using a 90 donor car to convert the 93 to a manual I've been reading on a few threads and I've heard the 90-91 ecu's were year specific? My question is if the 90 ecu will work in the 93 when I do the conversion. I'm also planning on going for it this weekend on the 24th so some quick knowledgable answers would be greatly appreciated. Please get back to me ASAP! Thanks!

 

as long as it's the same motor, It should be ok. I do believe both cars are obd1?

 

That's the thing I'm not sure if the 1990 integra gs is or not how can you tell?

 

Nope, nevermind. a 90 Integra is OBD0. U will have to get an OBD1 manual ECU. What motor are you running? If it's an LS just get a p75 from a manual teggy from a junk yard.

 

I'm runnning b18a1 in both cars so it won't work?

 

the ECU will not, it's a diff OBD. you need a Manual OBD1 LS ecu
