setting shift light

[BoostedH23a1]

I NEED HELP! I have a s200 system attached to my p72 ecu. Every time I try to set my rev-limits it doesn't work. Here is what happens:

1. I turn the ignition on but don't start the car.
2. I press the button once and the light flashes twice, pauses then flashes once every second.
3. I press the brake to get to the launch limiter mode, NO FLASHES, I thought the light was supposed to start flashing the thousands of revs? It's like it completely shuts the unit off and I have to start over.

.When I try to set the shift light it comes on at 2100rpm. What am I doing wrong?
