xHP on Sale

[B21]

xHP doesn’t support the Z4 8HP apparently. They’ve said to me that they’ve moved to the G29 now. This is one message they sent me. Thought it would be worth raising that just in case someone coughs up only to be disappointed.
Hi,
unfortunately the demand for them was to low, and we have not developed on the Z4 TCU firmware.

It’s true unfortunately..but the 6HP is the real benefactor of xHP as the 8HP shifts pretty quick and isn’t torque limited as far as the N20 goes
