MikeR, I have found that procedure doesn't always work for certain, the only true way is to disconnect the battery, and I do this especially at the track...in fact, I am looking for a way to install a cut-off switch, similar to what you would see on a marine engine...I get to the track, pull the cut-off, put a couple bags of ice on SC...and wait my turn...I have a Sprint Booster in-line, and don't know if this causes the problem or not, but I haven't always got a true reset...
