https://cimg4.ibsrv.net/gimg/www.mia...3db65eb1d8.jpgSo it is the sensor. With the engine off. It reads 32, then as the data log shows drops off and stalls. The Ambeint KPA where I live is 101 right now. Any ideas?

You have made the wrong selection regarding which map sensor your megasquirt is equipped with. Simply choose the correct map sensor in TS and it should display 101 kPa when the engine is not running.

What MS variant is this?

MS1 PNP he says in his build thread. He's got it set for 115kpa in the engine constants instead of 250kpa I'm guessing.
