Well i got a 91 CRX DX with a ZC engine in it for some reason the person i got it from has a 90 ls 1.8L ECU it it not sure why but he does i am going to be getting a 88-89 ecu from a friend how much should i pay for the ecu and will it plug into up with the wireing harness thats in my car right now any help on this would be great i can use my moms digi here soon to get some pics so u guys can see whats going on... if it doesnt fit i will be looking for a DX harness and modify it i will have to get some info on how so that would be helpful to and thx

 

Why do you need to replace the ECU is it not running right? Or are you getting a proper ZC ECU?

 

well from everything i have read no one i have seen has put a 90 int 1.8l ecu on the zc 1.6 plus i have a check engine light and its tossing me codes from all the research i have done ppl but in the 88-89 int ecu or the crx si or the ZC ecu i have yet to see a 90 int ecu go in there plus its running really rich i can just smell it all the time when i am stopped or backing up

 

plz anyone that has gone through this or even mabey if u have a 90 ecu that runs fine let me know plz
