Important Compatibility Info: MSPNP on 94+ 1.6
This is stated on our website, but as this is something that I had to deal with today, I'm hoping that spreading this info around may help prevent future incidents.
If you drive a 94-97 1.6 Euro Miata and would like to install a MSPNP ECU, please please please order a MM9093 ECU
. The Euro 94-97 1.6 Miata wiring harness is very closely related to the 90-93 1.6 cars, and quite different than its contemporary 1.8 counterparts.
If you install a MM9495 or MM9697 ECU into your 94+ 1.6 Miata, you will badly damage the ECU.
Conversely, we have not had any trouble running our MM9093 ECU on these later model Euro 1.6 cars. What we have seen is that non immobilizer equipped 94-97 Miatas are plug and play with the MM9093 ECU, while immobilizer equipped cars need to have 1 wire moved in their harness, as the immobilizer intercepts the fuel pump trigger. (This information shared in good faith and is to the best of our knowledge).
