Ok the ECU controls the Fuel/Air ratio, right? And the Protege ECU is giving tuners problems under 3500 rpm, right? I know FM makes ECU for their Miatas. My question is could the Miata ECU be used in the Protege? I don't think the fact that it's RWD makes a difference...would it? It's a 1.8L, which the old Protege engines were 1.8L, too. So if the Miata ECU could talk to the Protege engine, would that solve some problems?
