Does anyone have the datasheet of stock VW VR6 coils # 021905106 or possibly tested on the bench?
I did some research in Google and found some folks saying they used this: running dwell of 3.2ms at 13.2v, cranking dwell 6ms on an 400whp engine.
Others said: dwell time between 2.6ms, 2.8ms or 3ms, cranking dwell of 5ms and minimum discharge period of 0.5ms, with a 1 ohm 5 watts resistor on 12v.
What could be a resonable “minimum discharge period”, 0.5, 1.0 or 1.9 like on the Bosch Double Fire Coil # 0 221 503 002?
So wich one is the correct or better dwell settings to Speeduino? :) :)
