99-00 MS-1 Parallel complete
 

For sale is the Megasquirt that ran my car for 1 and 1/2 years, just removed today.

1) The MS is a MS-1 v 3.0, it wasn't built by me, but I'm pretty sure R7 and R4 were removed. It was built following the instructions of https://www.miataturbo.net/forum/t13676/.
2) Comes with Parallel boomslang harness. Complete PNP between stock ECU. The only wires you have to connect and run through the firewall are the 2 CAS signal wires and the O2 sensor signal.
3) CAS from I believe a '97 Miata. This CAS comes with a brand new O-ring that was never installed, and the pigtail is included.

This unit was setup to run all the stock '99-00 sensors with the exception of the CAS retrofit. I have wiring diagrams for everything, the CAS, the harness, the MS. The MS was easythermed and calibrated for correct IAT and CLT readings.

So you get the MS, the CAS, and the parallel harness. All for $450. I'll even send pictures so the new installation will be hastle free. Like I said, this ran my car for 1 1/2 years, and I feel this was a great learning tool.

That is a GOOD DEAL! Someone better jump on this shit

It is a SUPER good deal. In fact, you could even use this MS for a 90-97 miata, you would just need a different harness. You probably would need to reburn the firmware though so the older sensors would be calibrated properly. I just realized this...a brand new voo-doo box from FM is like $420? So instead of a stock injector pulse width extender, for $30 more you are getting a fully programmable ECU that controls fuel, timing, whatever injectors you want, and much much more, and everything is included.

Very similar to my MS setup! Works great on my 2000.

Better deal...Price reduced to $425 shipped anywhere in US, priority mail and fully insured.

Did I say $425? I meant $400. This is the deal of the Month.
