Unhook MSD when uploading a tune?
I thought I remembered a thread awhile ago where someone said that it was a good idea to unhook your MSD ignition box when you were programming your PCM with a laptop. Does anyone else follow this school of thought? And if so, what would be the safest way to go - just unhook the positive lead from where it connects to the battery?
