Craig if you want I can move this to an ecushit thread if it's highjack!! Yar!

Launch Control (LC)
The most requested feature is launch control. This is an alternate RPM limit that is activated when the vehicle is NOT moving and the clutch is depressed. After quickly giving the engine full throttle, the launch control (LC) RPM limit is enabled and RPM’s will hold at a preset point (example 3000 RPM). As soon as the clutch is release and the vehicle speed raises, the RPM limit now resorts back to the main RPM limit (Redline or 7500+ RPM). This allows for consistent launching while doing drag racing. While LC is enabled and working, the actual launch RPM can be adjusted by moving the cruise control stick up to raise the RPM, or down to lower the RPM.

Flat Foot Shifting (FFS)
Another really cool feature we utilize is Flat Foot Shifting. Flat Foot Shifting (FFS) is something that goes by many names, but they all do the same basic thing. When FFS is enabled, this means that you can be at full throttle and shift to the next higher gear without having to lift your foot off the gas pedal! This has a lot of benefits, but mainly its that it maintains speed during shifting. It also allows for faster and smoother shifts, which all leads to faster lap times. FFS is enabled any time the engine is at full throttle, and the clutch gets depressed. The ECU looks at the current RPM and cuts the fuel until the RPM drops to match the next gear. For instance, if you are full throttle in 3rd gear at 6000RPM and you push in the clutch (keeping your foot full throttle) the RPM’s will drop roughly 1000RPM to match the next higher gear. This feature works from 2000RPM to redline. That means you can give the engine full throttle at 4000RPM in 2nd gear, shift to the next higher gear and the ECU will drop the RPM’s to match going into 3rd. So it can be used in all situations, not just shifting at redline.

Auto Blip Down Shift (ABDS)
Lastly is the Auto-Blip Downshift feature to help with decelerating and changing to the next lower gear. When Auto-Blip Downshift (ABDS) is enable, it helps with blipping the throttle to raise the RPM to better match the next lower gear while downshifting. Normally this is done using the Heel-Toe method of downshifting, where you have your right foot on the brake and gas at the same time and while you are braking, you roll your foot over to the gas pedal and give it a blip to raise the RPM’s up. ABDS is setup so you just need to use your right foot to brake with and the ECU does the blipping. With this feature enabled, it is activated when your foot is pressing on the brake, and then you depress the clutch to downshift to the next lower gear. The ECU will automatically blip the throttle to raise the RPM to match the next gear. It does not work if you press in the clutch then hit the brakes, only if you hit the brakes then operate the clutch. Example of this working is say you are at 4000RPM in 4th gear and you are approaching a turn that requires 3rd gear. As you apply the brakes, then hit the clutch and start to shift to 3rd gear, the ECU raises the RPM to roughly 5000RPM to match the next lower gear. As you release the clutch in 3rd gear, the RPM’s will be matched and you will be able to smoothly accelerate through the turn.
