Anybody know if the 94 link ecu works on 90 miata with 1.8 swap? Should I just swap out the wiring also, since I'm still using the 1.6 wiring and MAF?

 

The sensors are different. Also the 90 uses an AFM not a MAF. Thats why some ecu's splice in to the 90's AFM harness. It won't be PnP on a 90 though, it will take some modding. Run the MAF delete programming, and it should give you less hurdles to jump.

 

a PnP MS would be better
