MSD & a two step
Just curious on how many racers use a two step for a launch control & how many use it as a safety device, putting in a chip that's a little above your convertor stall?...I personally use it as a saftey device. What do you do?

launch control, more consistent this way for sure.

I use a three step, burnout, starting line, and high side.

I've never had a problem with being consistant, 60ft times don't vary much. Except when I used to Super Gas race with a Chevy Monza with a 12 bolt rear and I chucked a rearend on the starting line...60 ft sucked on that pass. Now they vary from track to track a little. I feel a 2 or 3 step is hard on the engine. JMO

TS1955 fluid temps changes, fluid gets thinner when it gets hot and the stall changes, meaning it could go from (example) 1.20 to 1.21-1.215 |
I'll answer Tods question first. As long as you have your tranny brake activated and you are on the "low" side of the two step, the high side chip doesn't function. So if by chance you come up on the converter and it breaks, you have NO safe guard. Unless you have a chip in the low side.
When I used to Super Gas race I would leave the line at what ever the converter would stall at for reaction time. I got used to it and haven't changed. Hope this helps. And hammertime my 60 ft will vary about .01-.015 about the same as yours. TS1955 |

I didn't think about the high side being shut off while the button was in....duh. :D |
Hammer, I see that was an example now you pointed it out. But, that's about what mine varies. Sometimes I'll roll in a tiny bit more from time to time. I did try the 2 step for a weekend a couple of years back.
