Does anyone have any idea what I should set this at on a progressive? Its a stock 02 ls1 motor.

 

Just below what you see at WOT

 

This is the thing.. The way the nos launcher works.. I can not see what the voltage is at WOT.

 

I think mine is about 4.5V on the Trick Window Switch. If you have the ability to program it, turn the key on, and put the throttle say 80-90% to the floor, and hit the program button (if it has one and is programmed the way some window switches are). That will tell it 80-90% is WOT.

 

So you have to tell it 4.50 volts?

If so start high and test it when it works set it .2 lower.
(test is with the car off and no N20 in the line if you can)

Where did you but it?

What do the instructions say?
