I've been having a search around to see what combination of circumstances triggers / engages the transient overboost on the TDCi motors.
Ford make a big play of this feature in all its tech specs, but so far I've only found fairly vague descriptions such as " it happens when full acceleration is required" or "under hard acceleration". Nothing technical, or more detailed about when it happens, and the circumstances.
I'd be very interested to know:
--> is it only triggered when the pedal is floored (similar to kickdown in an automatic)?
--> or is the ECU clever enough to give overboost if the pedal is 'stabbed' quickly, over a certain defined range of pedal travel?
--> is it only available in certain conditions (i.e. coolant / oil temp above a certain range, exhaust gas temp in a certain range etc)
I would have thought the driver has to actively initiate it with a determined right foot -- especially after the "unintended acceleration" lawsuit that hit Audi in the US in the 80s.
Any thoughts / input / links gratefully received.
