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

Use the '94 wiring diagrams from here. The yanks were a year behind us in releases. So an Australian 93 MX5 is a US 94 Miata.

There are only minor differences on the PCB of the 1993-1995 NA8 ECUs. Pins are the same on the Australian delivered versions. Both Manga_Blue & I have run the final 1995 NA8 ECU in our earlier NA8s (mine 1993 & Manga's 1995). I've even run 1994 NA8 ECUs in my 1993 NA8, including Japanese Domeistic Market 1994 NA8 ECUs.

New NA8 ECU was end 1995/ beginning of 1996 to 1997 - apart from major differences on the PCB, the ECU plug is also different.
