Anonymous Unregistered A	Because of the throttle application? There is no throttle hence a vaccuum and it reverts to idle settings? I dunno. Just guessing. Ross

It doesn't care about the wheels or gearbox; it just says if it's doing more than about 1500 rpm and the throttle is closed, then it kills the injector pulses. As the engine speed drop, it keeps an eye on it. When it gets to 1500 or so (depends on engine temperature, I think) it does what they call a 'soft start' which presumably feeds in the pulses gradually; when it gets to idle speed it's working as normal.
