Hi fellas, have a 1993 civic ex that has a bad ecu. Not sure if it's even the correct one. Can any of you tell me the right one? 1.6L VTEC, automatic trans. in California. What I've got is a 37820-P28-A52 ARA. Your help would be greatly appreciated. Thanks

 

I had my ecu go bad not too long ago. I bought a rebuilt one from this website: www.hamotorsports.com

This page here (https://www.hamotorsports.com/pages/...plication-list) can give you the list of what ecu's fit for your car. By the looks of it you do have the right one, at least to my knowledge.

 

Thanks for the reply and the link for that list. Good info. I also called the parts dept. of a local honda dealership, gave them my vin, and they were able to look up what ecu part number the car needed. Turns out it takes a 37820-P28-L51 or A51. Thanks for you help.
