Launch Control

Same thing happened to me but the problem was sitting on the driver's seat. I had to push the acceleration pedal faster to the floor, otherwise the APP threshold (98%?) is not met for the LC function to activate and the RPM will simply raising above the target LC RPM.

Can you verify that you were > 98% APP? Below 98% APP, it uses the normal limiter. It is configurable in tune customizer.

I had the dashboard and laptop hooled up to the car. App was definately at 100% I tried to change the APP to 70% but don't see any difference

Hey guys. I finallly got it to work. I loaded the high load map from the tune database then the launch control parameters were shown and after the flash It worked like a charm. Truely impressed. Great work guys!

Speaking of launch control, are you able to change 98% APP limit? I'm not, it always returns to this value when Versatuner is started again. RPM change it takes but not APP.

I did change it but I'm not sure if the actually written value was 98% or what I had set in there (90% as I lowered the rev LC rpm to 3500 and it was hard to have the APP to 98% before the engine speed was 3500 - anyway it was working fine).
