I am selling my megasquirt MS1 3.0. I had bought it from another member that was running parallel on his stock 97 miata. I bought it with intention of using it in parallel on my 99. I have the Megasuirt, the parallel harness, 3' DB37 cable, the 9 pin serial cable, and USB adapter. I also have a CAS from a 97 with the pigtail. If someone wants to use this in parallel on their 99, I can cut you a package deal. MS, harness, all the cables, and the CAS with the pigtail for $500 shipped. Make offers on seperate parts. Selling cause I have a million other things to work on aside from the miata project, and I think I might try to build an MS-II to work with stock sensors instead of using the CAS.
