They offer Stage 4 I believe, but I haven't opened that app in a long time. You can set your shift points, however I'm not sure about the part throttle ones based on load or whatever it is.
Currently all that I see is WOT/kickdown on/off shift points that you can edit. I think part throttle/load based shift points will be editable soon. Stage 4 is a track tune.

So i just need to pull the trigger on stage 3. But can anyone confirm if I need to check kickdown box if I have it off through mhd?

I have a question for xHP, I have a 2009 335I that i will be doing a trans valve body rebuild, along with new gaskets and seals. I currently have xHP Stage 3 installed, i was going to do an adaptation reset along with the proper relearn procedure. Do i need to flash back to stock TCM tune before doing the adaptaion reset and relearn or should i leave xHP installed?

Thank you in advance!

Last time I flashed (stage2->3), it reset my adaptations as part of the flash anyway. I don't think there's any benefit to going to stock first.

Hello, so I just did a single conversion. Should I be running stage 3 v1.5? Or stick with v2.2?

I’m not sure about the question of whether you should put back to stock, you’ll have to wait for them to reply.

But if you do the reset make sure you follow it properly, lots of people mess things up!
