I just finished the pdm course, and they reference the ecumaster pmu16, and had all 4 ign1a to just a 10a steady circuit... I was under the impression that each coil draws up to 25a or so. So I was gonna run 2 pairs of coils for each 25a circuit. Needing 3 circuits to supply 6 coils... does this sound right?
My testing of these coils has them hitting their coil saturation point just over 20A, but this is the peak current draw. The average current draw when dwelling is under 10A and over an engine cycle is even less. Depending on what the part number and revision of the particular IGN1A coil being used, the dwell can be as low as 1.8msec @ 14V whilst drawing 19A.
I'm using the haltech branded ign1a coils.
How many coils were you using? All of them average roughly 10a only? Thanks
Are these the ones with the Part number of HT-020114?
Running these at 85% of the saturation point, they drew 6A through the voltage range that I tested them on, they have a 4.1ms dwell @ 14V drawing 6A. You can push a bit more dwell (5.3ms @ 14V will draw 10A) into them and they will draw more current, but they get hot quite quickly as the coil is fully saturated. They also self discharged if the dwell was pushed further.
This would be okay on a drag car that does it's run and is then cooled down, but not on a road or race car.
I test a single coil at a time, but I have cross validated the results that I get on our dyno test engines.
