Hi all and thanks,all power and grounds at ECU are good.I agree that the topping of the coil current is due to ECU control but,why is it having to apply this strategy? It appears to be switch the coil to ground too early or holding the firing point latter than it expected? I have been re-vieuing the live data and you can see the stall coming,I'll try to post it.



Q: How does the ECU decide when to starting charging the coils so there is sufficient voltage at time of discharge?
