Soft Rev Limit Control.
- A more sympathetic alternative to anti-lag.
- Launch control on the move.

Sometimes you can leave the launch control on during hard driving and use it instead of the much more severe anti-lag (Motec and Gems) system employed by grpA and WRC rally cars.
Each time the clutch is depressed at engine rpm higher than the set rev limit, the turbo runs in after burn mode. The turbo is able to maintain its speed during gear change. Along with the after burn, the throttle is kept open and air is free to course into the engine from the compressor (rather than hitting a closed throttle plate), which allows the compressor to coast more freely. This system is so effective that a bigger/heavier turbo can actually be an advantage because of the flywheel effect keeping the compressor turning.
Along with the benefits to acceleration, there is also a benefit in that the drive never has to lift off the throttle during up or down shifts. This means you don’t have to worry about heel and toeing into and out of the corner. The rev limiter will hold the revs at safe levels.
