I bought a 1993 del sol that had a previous engine swap. The guy that sold the car said it did not have a ECU swap and it still needed that to run correctly. The car has a ZC non-z-tech 16 valve engine. It currently has a 37820-P28-A01 ECU. The car is a manual transmission and will only go up to 3900 rpm's then cuts out like governs itself. What ECU do I need. I was thinking the 37820-P06-A02. Does anyone has any feedback for me. Do you think this will fix my issue. Any feedback would be greatly appreciated.
