Duramax 2 step

2 Step

Use a DSP5 tune and use 2 tunes. One tune (while on the trans brake) will only rev to your limit and tune 2 is when you release the trans brake. It worked excellent on the dragster.

Cool idea! I would have liked one while on the brake with my old 12v cars
 
And put it on a button so you don't have to flick a dial to leave the line :D
 
RELAY

Mine was done with a couple relays. When on the brake it would switch on the two step tune. When the brake was released it would go to the hot tune. You can also use the other 3 positions and make tunes so bad/loose track conditions. All done with timers or buttons. Just like a video game. LOL
