ZF6 gearbox flash

[Lee630i]

Once I get my injectors replaced, I will be looking into a gearbox flash to speed up the changes on my 6 speed auto

Seen reviews on the XHP which seem to be great, but doing research there seems to be an Alpina version aswell which seems a bit more sedate in comparison and will suit the daily commute better.

Does anyone know of anyone providing this service?

XHP stage 3 is perfect in auto. If anything smoother as changes are quicker in a good way and a lot less dim witted and less eager to downshift, instead riding the torque a bit better. It’s a bit OTT in sport but I generally drive auto or manual on the paddles. Have a kickdown blocker under the accelerator pedal and kickdown disabled in the XHP map so can use full throttle from 1k rpm without interference.

Wouldn’t go back.

That’s on my 335i touring. Will map the 650i(6hp26) when the mechatronics seals, filter and fluid have been changed
