First Part of Dwell Time Measurements:

Today i finally got my measure setup in the car complete and could measure the stock dwell time for the EDM CA18DET ECU.
I used the quickest Sample Rate available at 0.1ms and measured at 850rpm in Idle. I'm going to measure all other rpm's in 500rpm increments within the next few days.
Seems to be around 3ms for 850rpm.

I did some more measurements today at 2500rpm, 3000rpm and 5000rpm and the Stock ROM will adjust the Dwell to 1.75ms throughout the Rev Range.
My plan now is to adjust the base "Dwell Time" Table and scale the Dwell Duty at idle rpm down to avoid overheating the Coils.
