A few weeks ago I was helping a friend tune his car with a Haltech Platinum. We tune the launch control and his 60' in the strip came down from 2.2 to 1.9.



I was thinking that that could be done to my car using the Two Step on my MSD DIS 2. I would need a relay (or something) that can be activated with the signal from the speed sensor and the rest would be a thing of playing around with a few cables.



Another thing I need is more info on the speed sensor signal.



Thanks.
