Pretty cool trick, on a subaru you can only do this with an accessport ver. 2 or an utec tune. It can fuck up some internals if not used properly.

heres a video of an STi with a two step. http://videos.streetfire.net/video/4...e500fd1db1.htm

well i understand that function and all but i've installed a 3 step aka no lift to shift....

How does the "3-step" rev limiter work?
The 3-step gives you 3 different rev limits, depending upon the postion of the clutch pedal, and whether or not the car is moving. If the clutch is NOT pushed in, you will always get the standard, highest rev limit. If the car is NOT moving when the clutch is pushed in, you will get the lowest, launch rpm, to build boost off the line. Once the car is moving, and the clutch is pushed in, you get a third rev limit, sometimes called the "no-lift-to-shift" or "flat-shifting" rev limiter. This rev limit allows you to keep the gas pedal pressed to the floor in between shifts, so the turbo stays spooled. The use of this feature is recommended ONLY for guys with REALLY good transmissions. But, PLEASE NOTE that even if you order this feature (6000 rpm recommended) you do NOT have to use it. The car will shift and run normally, as long as you do not keep the gas pedal flat to the floor between shifts. ALSO NOTE: The 3-step requires a functioning clutchswitch, and wiring modifications to the switch and ECU harness.

and its a no lift to shift feature on a DSM not a cute lil scooby
