I've been wondering the same thing.
Thought about trying it and just keeping a spare coil in the car but I figured the ecu would be safe since its power doesn't run thru the ballast.



No but the coil primary runs thru the ECU box at thats what grounds the coil primary and if you up the coil pos volts from 5-7 to 12 it will put more current flow thru the coil ground side of the ECU box. Dont know if it would be enough more to hurt the ECU box but it could. Thanks for all the replies. Ron
