1990 Mighty Max Burning too much fuel problem.

What Josh said - not going to work. Not properly anyway.

You need to look for the Mitsu # on the outside of the case... tpyically MD###### Then start looking for an identical part number.

Thank you all for your help. Is it possible to use a California ecu in a non-California emissions truck?

is anybody know his question. just related to mine but just updated it.

LED lights are every where. This technology is great. Thanks for mentioning another benefit of LED lights.

Was this ever fixed? I may have missed but di you check your timing?

I have a 1990 MM Marco Cab that was doing the same thing, 12MPG and poor acceleration. I replaced the capacitors in the ECU from a kit from Mach V Motorsports and now gas mileage is way better.

More details of the problem I had and solution
