Johnny,

you're going to need the manual gear cut function. You can normally choose any spare input, but as you suggest, switching to ground is the simplest (but not only) option. Using a spare AR or AU input would be ideal. If you're on a sequential then if it has a gear position sensor it would allow you to take advantage of the closed loop control (it will realise when the shift has happened by virtue of the gear sensor voltage rather than you releasing the gear lever). If you don't have such a sensor then it is best to set the "End of request ends cut" option and maximise the cut time, it can always be cut short but you don't want it ending mid-shift. I would run somewhere in the region of 10 degrees retard as torque fade-out, then 20 degrees retard and 75% fuel cut in the main cut, back to 10 degrees retard ramp in before going back to full torque. That has worked well on a few cars, holds the boost steady where it is and doesn't allow the revs to shoot up as the dogs are unloaded You'll most likely have to play around with what works best for your 'box though

Cheers,

Pat.
