Hello, I have been struggling trying to figure out how to get my APR Stage 2 tune to work nicely with ESP and traction control without having it feel neutered like stock where it's pulling torque. I can go full ESP off and it feels like it should for stage 2. The car is a 2014 Audi A5 with flex fuel CPMB and ZF 8 speed Auto Trans. Nothing wrong mechanically, car is sound. Feels more like torque management cutting in, and trying to experiment with coding of ESP to see if it helps a little. Our platform is dead for TCU tuning help. :(

I understand the precaution of playing with coding in the ABS Module, but I'm wondering if changing from "2D1D1801" to "291D1801" does anything. Seems like the ZF equipped b8's with 4 cylinders ran "2D" in the original coding. The S4/S5 b8s ran "29" at the beginning of the coding of the ABS Module. Does this correlate to letting ABS know which trans the car has or how sporty it is?

I'm attaching my quick scan log. The engine DTC is due to an aftermarket diverter valve, which I have since reverted back to factory with no DTC's set anymore.

P.S: I apologize if this is in the wrong section.

I can't find any documentation regarding Byte 0 in that ABS. My guess is the ABS will complain that it is "Incorrectly Coded" if you change it from 2D to 29, and that it's more likely defines the engine type than something regarding the transmission behavior.

I changed the coding last night from 2D to 29, so far no coding issues or rejection. ESP and traction control fully on seems to have more torque with less intervention, transmission still behaves the same. I'm going to give it a week to relearn before jumping to conclusions. Thank you for looking into it on your side!

Also, my driving habits involve more spirited driving, and using the manual shift mode 80%-90% of the time.
