Default Dedenbear Lighting Plus L2 Help

Hello, we have an '88 BOS chassis with a 700HP SBC engine & shorty powerglide trans. The L2 came with the chassis and we've got it set up and functioning for Pro Tree, Super Comp, however when I press the button for full tree mode I have problems.

For full tree I'm trying NOT to use the throttle stop and just rely on the "chip" or starting line and burn out RPM control. How do I shut off the throttle stop function in full tree?

Dennis
We are brand new to racing so all help is appreciated.

Press the 'STOPA' button repeatedly to cycle through the various timers. Make sure all of them are set to 0.000.

Alternatively, on the last screen of the cycle, you can turn the stop OFF completely.

Then do the same using the 'STOPB' button.

If you know which output your throttle stop is connected to, you only need to cycle through the options for the applicable timer.
