I'm surprised this is reliable, because switching back out of my security map has never been fast or reliable. I run a second map that's limited to like 4mph and 3Krpm, which I put the car in to leave it idling while I run into a convenience store or whatever. Usually if I quickly switch maps and pull right out of the parking lot, the ECU is still half-stuck (it starts to go then gets hung up limiting itself at say 5K rpm, and I have to come back to a stop or cruise for a while before it fixes itself). It tends to work reliably only if I switch back to my normal map and sit there in the parking lot for ~30s before I move.
