ECU/ECM advice for a 1991 RX-7
 

The ECU/ECM for my 1991 RX-7 (model #N352) has water damage and needs to be replaced. After calling several Mazda dealers and a national Mazda number, nobody can tell me which ECUs will work for this car. I don't want to replicate the current N352 ECU since the car was manufactured for California emmissions standards.

Anybody know which ECUs will work?

1991 RX-7 convertible, 13B engine, auto.

Thanks,
David

Thanks for the clear advice. What kind of condition is the N353 in, and how much $ do you need to part with it?

Regards,
