T-Sport Flat-Shift/Launch Control (long)
I don't know if anyone on here reads Autospeed or not, but I get there weekly email/newsletter. It's an Australian publication on the net and it's all about cars and how to make them faster/handle better.
Anyway, in there latest advertisement for their online store they featured this little thing :

And this is what they said about it :

The T-SPORT Flat-Shift is a perfect accessory for high powered Turbo All Wheel Drive supercars as full boost launches become second nature with a pre-set secondary rev limiter allowing the turbo to spool up while the car is stationary. No more blipping the throttle in the vain hope of building up some boost!
Flat-Shift can eliminate those frustrating and sometimes embarrassing "bog downs" off the line by perfectly matching revs to your pre-set limit every single time. It also allows full boost to be retained on up shifts as your right foot never has to leave the floor because the Flat-Shift cuts engine power for the fraction of a second that you have the clutch pedal down meaning your engine has no time to bleed boost pressure between gears.
If you're keen to beat the competition, no matter if you're at the drag strip or on the street, Flat-Shift allows you to claim the 10ths of a second per gear change and blast off the line on full boost giving you almost unbelievable 60ft times. Try to imagine how much extra power you would need to gain those 10ths using brute power and how much that power would cost.
Perfect for high powered AWD Turbos.
Keeps your turbo spooled.
Builds full boost on the start line.
Allows Wide Open Throttle gearchanges.
Includes a wiring loom, a long travel clutch switch and installation instructions.
Additional Information
We've all seen it at Drag Race meetings. A typical pro stock car pulls up to the christmas tree, stages and just as the lights start counting down the engine hits full noise seeming to bounce off a rev limiter. In fact, the driver has just pushed the throttle pedal absolutley flat to the floor and he doesn't lift off until the car passes the finish line because the engine has a launch control and flat shift system installed. Once a feature only available to professional race teams or those willing to install a $3,000+ after market engine management system, T-SPORT has now made this feature available to all car enthusiats for
How It Works
T-SPORT Flat shift features a RISC Microprocessor that runs at 4 MHz that monitors engine rpm 50 times per second. If rpm is equal to or above the set 'trigger' rpm level and the clutch pedal is depressed, Flat-Shift cuts power to the fuel injectors via the main 12v power rail. Some multi coil systems also have the positive side of their ignition coils on the same 12v bus so spark is cut at the same time. As a back up for cars with their ignition coils on a seperate 12v supply, Flat-Shift features an output that connects to the crank angle sensor to turn off the timing signal while power is being reduced which will also cut spark.
Flat-Shift primarily uses fuel cut to reduce power and keep rpm at the set 'trigger' point because on modern EFI, catalytic converter equiped cars it is not wize to use an ignition only rev limiter as unburnt fuel passing through the cat will very quickly destroy it. Ignition cut is used in tandem with fuel cut so that miss firing and leaning out are minimized during the power reduction cycle.
Install
Installing Flat-Shift is generally fairly simple as the main 12v power bus for the fuel injectors usually runs through the vehicles fuse box so is easy to locate and tap into. This source is also used to provide power for Flat-Shifts electronics. Other connections include hooking up the tacho signal, connecting to the crank angle sensor (if needed), mounting and connecting the clutch switch along with a good earth connection and that's about it.
Set Up
T-Sport suggest setting Flat-Shift approx 2,000 rpm below your red line or shift point for optimum performance. T-SPORT Rev-Lite is perfect for keeping an eye on your shift point without having to keep looking down at the tacho.
Setting the RPM level you require on launch and shifts is as simple as holding down the 'set' button when you start the engine,( 2 LEDs on the front panel will flash once letting you know you have put Flat-Shift into 'set' mode) bring the engine revs up to where you want and release the 'set' button ( the 2 LEDs will flash twice to confirm your new setting) Each new RPM setting is burned into the Flat-Shifts EEPROM and stays set even if the battery is removed from the vehicle.
