You can't leave off of a button in Stock, unless it's on the brake pedal, as of last year.

Like so:http://i128.photobucket.com/albums/p...c/100_2226.jpg


The switch on the shifter is for low gear only activation of the two step.

First of all, if I am not mistaken I thought it was legal to leave off a button and 2 step in stock, but not a transbrake. Maybe this is just an NHRA rule and not legal in IHRA. At any rate, with some bracket tracks going No Box instead of footrbake and not thinking my car would be suited to a transbrake leave I was thinking about this. If this is something anyone has played with how do you mount the button. I have heard of them being on the foot brake, but can you use just any old button to do it this way since you will be applying quite a bit of pressure to the butto? Or, is it just as easy to let go of the button with your finger and the footbrake at the same time? How much RT can be gained by leaving off a button and a low side pill vs. off just the footbrake?

Mark,

I'm pleading to please accept my ignorance here. I'm slowly trying to reacquaint myself after all these years, I'm not familar with a 2 step (or a 3 step for that matter).

Is the switch on the brake pedal used simply as a rev limiter, limiting the amount of rpm's that you stall the converter? Also, is the switch on your shifter wired in conjunction with the roll control? This allowing you to control the peak rpm during your burnout.

U need to check with the track you are running at because I have had problems in the past trying to do that "no box" means no electronics to leave starting line including 2steps... just letting you in on past experinence

Robert, The 3 step is commonly used as such:
Module 1, used to limit starting line RPM.Usually an adjustable module
Module 2 , used for high side over- rev protection
Module 3 , used to limit burnout RPM, commonly hooked to the line loc
(Not used in car in picture.)

The switch on shifter is used to complete the 12V feed from the brake pedal button to the 3 step box for Module 1, in low gear only. That way, it won't activate when braking at the finish line.
