I confirmed accuracy of these tables on the scope today. Everything looks good.

This confirms ECU is using ATU CH2/CH8 one shot pulse for timing.

I am looking for dwell access for A4SGE01C. It is not in the xml. I had a coil go out FK0140 I decided to replace all 4 as they were quite old and had a lot of miles on them. I revived for 4 new FK0333 and am not sure of there latency of these coils and am having trouble finding any data on them.

Thanks

the FK0333's (22433AA561) should be the same dwell as the stock coils on a 02/03 US EJ205

Where can I find definitions for ignition dwell for 32bit ECUs?

I've recently replaced my worn 5ms coilpacks with 3ms ones in my EDM MY07 FXT, and I can't find the table to make the changes
