2STEP and anti-lag both work as normal with this change!

On the cruise you can always plug the wire back in with no setting changes needed on the JB4 side.

So I did everything as noted in the instructions however I notice now the clutch disengages harshly, and also my throttle seems SUPER sensitive. Ideas?

I'm going out to pull the DME cover and check everything out. Something can't be right, lol.

It's normal. I don't notice it anymore to be honest. Maybe the car adapts?

Hmm. Idk I found it to be sketchy as hell. The car wants to buck and the littlest pedal input makes the car jump forward. I was under the impression I have something wrong in my DME box (I just uninstalled the ***** at the same time). I uploaded a couple logs of just cruising down the street trying to capture the surging I'm talking about. Hoping there's something obvious in those.

Terry, is there a way to toggle the clutch input on the JB4 side instead of needing to plug or unplug the #18 wire on the harness if cruise control is needed?

Yes we're going to work on that eventually!

I can't really see anything in the log but makes sense shifting across the board may be more harsh like this.

Understood, I definitely notice a lot more "clunking" when shifting (especially at lower gears and speed), in one case tonight banging 2 to 3 I actually heard the synchro chirp and it was noticeably harder to get into gear.

Obviously these things are subjective and could quite possibly be specific to my car, and not someone else using this. Either way I know you're always looking for feedback, and I hope I can get this to work better on my car.

So far my single turbo 135i loves this! The car is so much more fun to drive and i can do half assed shifts and still go into full boost immediately after shifting. Its like going single turbo all over again, the only thing i noticed was that with the clutch wire unplugged the mhd burble doesn't work unless you feather the throttle on decel, then it will pop with the same intensity.

Terry, I know this is probably a dumb question, but is a backend flash (BMS or otherwise) required for this? I assume it's not since you would've inlcuded that in the instructions.

BEF is not required for this.

Very very excited for this in its final form! Do you have some kind of ETA, this feels like it could be one of the biggest advancements in a while.

I don't have an ETA for that but I'd encourage anyone who is having the shifting issue to try this out and provide feedback.

Tried it. Confirmed cruise control didn't work and reversed the change. I'll probably switch it again to get a couple logs, but loss of cruise is a deal breaker on a DD. Also noticed huge throttle input sensitivity at low rpm.

Ok loaded the 32_11_t1 firmaware and unhooked pin 18. Turned on bit 4 in wmi settings. Throttle response is crazy quick along with no bog at shift. However when i go WOT, car cuts power and pops a 2step/NLS code. Any ideas?

Should be easy to put a switch in the glovebox to quickly toggle the #18 wire on and off..

It's FutureUseD bit4... Not WMI settings.
