Hey guys, just wondering if anyone knows where i can find an ecu pinout diagram for a 93 na8 mx5? have been having some trouble finding one that is for this year model as it changes in the 94 1.8L

Huh.

I never realized that anybody got the 1.8l engine prior to '94.

I have the diagrams for the US-spec '90-'93 1.6 cars, but I have no idea whether they'd be relevant to your car. Does your have a mechanical AFM or a hotwire MAF sensor? Do the ignition coils have built-in igniters (four wires to each coil separately) or does it have the external igniter like the US-spec 1.6 cars?

Yeah they were delivered in australia and i think also in japan, they were sold in australia as an mx5 clubman, they came with the 1.8L engine

It had a hot wire maf, and as far as im aware it has built in igniter, but only 2 coils instead of 4, was having a look at the ecu layout for the 94 1.8L and its totally different, as the ecu is different
