2 Step tuning with Uprev

So... just put yourself in the rev-limited map, hold down the cruise button that you normally hold down while picking a map, pre-pick the wide-open map, and let off the cruise button to release the RPMs?

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.

Could anyone else chime in on this? I see you have an extensive list of mods could any of those throw it off? Could this be a difference between a 6MT and 7AT. Have you had any other trouble with your tune?

Good catch, I missed his sig when I commented. This will NOT work with an automatic since the ecu detects the brake signal and restricts the throttle. Its the same issue you run into when you try and brake boost (for the boosted guys). You have to disable the electronic throttle control completely (and lose your cruise control) or tap the wire running to the ecu that sends the brake signal.. and lose your brake lights. Not 100% sure tho, I did a bunch of research on it a while back but gave up once I realized just how smart the ECU is and how much work it would be to trick it into letting me do it
