    Ms1v3 PNP for m20 motronic 1.1-1.3

    This is a 55 pin megasquirt 1v3 setup I built based on the DIY from one of these forums a few years ago. It has the glens board for the stock 3 wire idle control valve. To make this work you will need to wire in the 15r from your fuse box to the main relay (very simple). I don't remember exactly what to do but the information should be simple, GM IAT sensor which you can get from DIY Autotune, Wide band oxygen sensor controller (see info below) I'm included a variable tps for the 2.5i throttle body. I lost the pigtail harness, but if I find it I will include it. The tune was for a 2.7i stroker I build a few years ago. I had an issue with my cold start that I never sorted out. Other then that it worked great.

    I'm also including an LC1 wideband controller which was damaged and believed to be dead. I thought the o2 sensor went bad so I purchased a new sensor (also included) The LC1 was throwing an o2 warmup code even with the new sensor which is why I think it's dead. The new sensor has 0 miles on it, maybe 30min run time tops.

    I'm letting this go very cheap due to I dont have this vehicle anymore and don't need it for my other e30's. I really don't have time to help with the install so please look in the forums for more information.

    I will take $250 shipped FIRM

      Definitely want this. Do you have any proof that it's functioning correctly (stim)? Unfortunately, I'm out of town until the 25th. If you still have it then, I'll be in touch.

      I'm located in Clearwater, FL.
