Maybe that wasn’t necessary if XHP are suggesting it updates it anyway.

I tried stage 1 for five minutes of driving and seemed no different to stock,
so I then flashed stage 2 and to me it was still pretty mild .
I’m on stage 3 now and in sports mode it shifts much faster but not harsh .
In normal mode even with stage 3 I don’t think anyone would really notice.

In sports mode with stage 3 as you slow it rev matches, which I think is dumb for a diesel.
There’s no way to disable that except by either just using stage 1 or 2 or just drive in normal mode .
There’s other options available to customize any of the stages -
lock out or enable 6th gear in sports mode;
Valet mode, drag race mode, and change when it upshifts and downshifts through the gears, rpm limit ,
and a few other options.

Thanks for insight into xhp. Do you happen to know if ista P can update the e53 transmission? I got ista D working all fine but haven't tried ista P. I researched doing the update via winkfp but was 100% sure on how to do it. Ista P I'm assuming is an easier process as it should identify the modules and their correct software rather than having to select it like in winkpf?
