HI,
Are you wanting to configure the dwell table for a set of coils being driven by the M1?
If so, there are two choices that you can do, the first being to send them into us through your local dealer and we generate a calibration for the coils, or you can do your own calibration.
To do your own calibration, you need access to the following tools;
- an oscilloscope
- a current clamp to suit the scope
- a variable voltage output power supply to test the coils at different power levels
- a 1 farad capacitor to supply adequate current to drive the coils
- a test rig with the coil driving a spark plug
Once this is setup, you use the M1 to drive the coils and read the dwell off of the scope.
