Interested in information on the Harlan Two Step device. Anyone using it? How does it work?

 

it intercepts the signals going to the coils and give you a second 'spark limiting' rev limiter where you can set it to your desired launch rpm.

if you have an automatic you can activate it by a remote switch or manual you can do it that way or witha clutch switch like i have mine. the idea is so you can have the throttle wide open off of the line.

 

So you hold the gas to the floor and it rev limits at say 4k for the launch and as soon as the clutch is let out it goes back to the regular limiter? What kind of clutch switch are you using. How much of a gain did you see or is it more of a consistancy thing?

 

I sent an email to Harlan.. he is away on business and will answer as soon as possible.

 

on a given night all my runs (that i hit all the gears) were within .2 (getting faster as the sun went down)

60' times were within .05 or so.

it REALLY helps out so that all of the launges are good, not 50/50 like my usual.

the other purpose of it is to build boost with it when i have the turbo on.. that will be a big help.
