Hey guys,
Need your help. I bought a 1996 Miata that has a ms3 basic, full bolts on. I’m taking the entire engine/exhaust setup and putting it in a 1990 Miata. The 1996 car has batch injection tune.
I’m buying a ms3 for my 1990´s wiring harness, and I want to keep the tune that is in the 1996.
1990-1993 cars have injectors connected for batch injection, while the 1996 is setup for sequential.
My question: since the tune is setup for batch injection, can I keep the injector wiring from the 1990, or do I need to modify it for sequential? The goal is to save the dyno tuning that was already done on the 1996 car I bought.

thanks!

Ben
