Is torque punch and torque reduction even necessary to play around with? I would think the ots flash from XHP is set to where they think is the best?
It is set to where XHP thinks is best but that does not work for everyone depending on power levels, and tune.
Some people have had to really turn Tq punch down to have it drive the way they want it to. Best to see what you want out of if and make one change at a time and test.

I've still got all the hardware ready to got M3 GTS via the GWS mod. However I don't want to change the diff. So the only way I can see to keep the original 2.56 FD is to go xHP. Has anyone flashed xHP on with no maps then done the GWS mod to allow you to keep the 2.56 FD ratio?

edit: Thinking about this more it doesn't make sense as flashing the GTS via Winkfp will erase xHP I assume so back to needing a diff to match better with the ratio the GTS map is expecting.

There is another way and will likely be known about more broadly soon ;)

I am new to this forum. I recently bought the xhp flash tool combo for my 2011 bmw 535i. My car was stock, everything was running fine until I flashed it :-(
After I flashed stage 1, as soon as I started the engine, it shows chassis stabilization malfunction. And I can't use the button to change to Sport and Sport + mode.
I tried flashed it back to stock , even uninstall the software. This chassis stabilization malfunction still shows up when I start the car. My Sport and Sport + worked perfectly fine before the flash. I don't know how to fix it now.

Can any expert here give me any suggestions?

If you really want the M3 GWS and the stock diff, there is someone on here that can provide a flash file. If you're fine with the factory GWS then go xHP and save yourself some hassle.

I'm running a custom TCU tune for a 2.81 diff and M3 GWS. My shift speed 6 setting won't upshift until 3500 rpm when part throttle and way higher under load. Makes for a great "full auto" track setting for guest drivers. And a lot of fun on the street.
