ECU has been flawless. Only selling b/c I'm now on a MSPNPPRO, to be on the same ECU as a Champcar team build for troubleshooting purposes.

MegaSquirt 3 ECU with MS3X Expansion, pre assembled version 3.57, wired with a DIYAutotune Break Out Board (DIYBOB) for PNP on a 94/95 car. It will pretty much get you the functional equivalent of a MSPNPPRO but won't have the real-time-clock, which just adds time to your log files on the internal SD card.

You could, with some instruction from Trubokitty, wire it for any 90-05 Miata, but on a 94/95 it will PNP for you.

It is also wired to run sequential ignition off the included options connector, you'd need to run 2 wires for the other coils (you'd need to do this for any Miata to run seq spark, even with a PNP ECU)

DIYAutotune Knock module is pre-installed on the board.

Boost solenoid is also pre-wired, just need to run the wire out to your solenoid from the options connector. VVT is also on this connector, ready to go, but I did not have a VVT motor.

Will include a 3 bar map sensor, the built in one on the ECU is 2.5 bar (~22psi boost max) which I repurposed for Baro correction. I ran the external 3 bar (~33psi boost max) as my MAP sensor. On a 94/95 this will PNP in through your old EGR sense wiring plug at the back of the motor, will include the pigtail adapter for this.

I have a Google Sheets document I can forward with all the pinout explanation / channel mapping. This should help for future feature DIY wiring or going from 94/95 to other years.

I'll include a USB B-A cable. This ECU has serial port built in, so you don't need an external Serial-USB adapter. Just a simple USB.

 

Sweet deal on a slick PnP job, GLWS.
