Audi A8 W12 (D4) - tweaking behaviour of engine and gearbox

[horrgakx]

Does anyone know if this can be done without visiting a specialist tuner?

• When the engine uses 6-cylinder mode it is either downhill or on flat. Anything much steeper than a flat road and it reverts back to using all 12 cylinders. I'd like to be able to increase the allowable output when using 6-cylinder mode.
• And the gearbox - ideally I'd love to be able to press the accelerator (not into to the kickdown switch) without it changing down - ie. for it to use all the torque of the engine in whatever gear is currently selected without kickdown.

Thanks in advance.

I do not think you will be able to change that via diagnostics.

Does your shifter not have a tiptronic gate?

No there's no gate on the shifter, like the modern ones do. Just buttons.

So no tiptronic function?

It became a habit with me once I got up to about 60 mph on the highway in top gear to engage tiptronic, which locked the transmission into top gear unless the vehicle speed dropped quite low.

Yeh it does have tiptronic mode, so yeh I could use that more
