MEFI 4 for sure.

However, I do not know if MC ever used MEFI 4a or 4bs but I would bet there is a part number on the ECM.

Charge your battery.

The other thread you posted in has a simple way to reset engine codes.

This may help with the identification.

Yup, I was wrong in my posting. I would bet all 07 MCX Mastercrafts are MEFI 5s.
