I used my MY99 to jump-start another car today, have I been a muppet? Will the ECU not like the possible voltage drop, or should it be ok?

I drove home and all seemed fine.

As long as you had it hooked up properly and were giving the engine some extra juice when the other vehicle was turned over there should not be any damage AFAIK - for some reason I end up having to help people quite often , no ill effects so far.:fingers crossed smiley:
