Alpina B3 Transmission Flash into X28i - N20/N26 vehicles? possible?

Has anyone successfully flashed the Alpina B3 Trans into the 8HP45 on the x28i model cars?

I heard of one person doing it on the F30 328i (which I have too) but thats all... just heard it. There is a thread concerning the 335i and I know we share the same transmission...

I currently have a 2012 F30 328i with sport+ and launch control coded in. its shifts pretty fast and it would be crazy to see it go any faster.

thoughts?

Is it like a quicker shifting program or is it a tune or what?

well, did some digging and it doesn't exist... F30 328i has the ZF8hp45 and the B3 has the ZF8hp70 .... It highly doubt that it won't work since they have different internals. Someone was fibbin.

In Sport+ the ZF up shifts at 150ms. The same as a Ferrari F430. Not sure how you can make a torque converter auto any faster.

Yeah the 70 is rated for 700nm/517hp input, 45 for 500nm/335hp. The housings are also different sizes.
