I noticed that too. It seems to fly through 1, 2, and 3rd in Sport Mode/S, IF I am too aggressive with throttle (anything over 30% throttle). Otherwise, it's fine. Also, under moderate/hard acceleration, I am getting a stall between 4->5 and then when it gets to 5th, it immediately upshifts to 6th. Don't know exactly what's going on, but it doesn't happen in the other modes. I'm sure it just has to be configured properly. UPDATE: reflashed and readapted with recommended 50 mile run-in procedure and issue went away. I didn't do adaption right first time; just drove aggressively and it didn't adapt smoothly. P.S Stage 3 , Sport Mode/Sport-Shift is a blast to drive anything above 40 MPH. Reminds me of the Audi S4 - very powerful and smooth at high speed. It's great throttle response and the way it effortless glides on the highway. Feels like your going 30 MPH less than what you are actually going. Sport Mode is too rough at low speeds though . On the other hand, Comfort mode is very smooth, but seems to lack power, and especially at highway speeds. This is relative to Sport mode, of course, because Comfort mode is obviously still laying down more power than with stock TCU tune. There is still a lot of custom options I haven't explored to fine tune it.

First attempt, 0-60 MPH with Racebox Mini Sport+, Manual mode, mini-launch with brake boosting to 2300 RPM...............4.97s (slope corrected) , with wheel chirp. I was only shifting at around ~4500RPM. I'm thinking I can probably get like 4.7s with full, proper, launch. I'm RWD and I doubt the HR springs are helping either.
WITH xHP STAGE 3 , SPORT+, MANUAL MODE WITHOUT xHP ...................................

On the Custom tune, WITH xHP, I got ~5 seconds flat (4.97s) - that was with wheel chirp and a soft launch, and lazy shifting. I feel that if modulate the throttle just right, and experiment I'd be around 4.7-4.8 s. I'm also very suspect that my lowering springs are costing me a tenth or two tenths seconds. With custom tune + xHP 60-100 is ~6.2s I don't honestly care about getting a perfect launch though. At a light, when I gradually tip into the throttle and avoid wheel spin, the car picks very smooth and powerfully - feels comparable to driving my Unitronic tuned Audi A4 Quattro (DCT tuned trans), with verified 4.6s 0-60.

I don't trust Racebox slope calculations. Did another run today 5.23s, this time with SPORT+ Mode, 74F deg , and light feathering into throttle - NO LAUNCH CONTROL. And I still got just a touch of late wheelspin. From what I'm gathering, LC will likely chop ~.5 seconds off that. I won't be able to get a proper launch with my HRs, though.

Does anyone know if the trans tune does anything towards the droning on B46’s?

But if you mean "droning" as vibrations under the load - you probably need to check and replace your engine mounts. |
