Hello, I'm in the process of fitting an aftermarket programmable ECU to an ex SPi Mini.
I've a question related to the trigger pattern of the standard SPi trigger wheel, in order to proceed.
Does anyone know what's the sensor position from TDC? (in Degrees BTDC cyl 1)
I suppose that information is somewhere contained in MEMS software.
Also, does anyone know what's the trigger polarity of the standard VR sensor? Falling or rising?
