I sent Evotech my C32 ME 2.81 unit (which supposedly is already set to 3.06 ratio), a new C32 TCM, and my old C320 TCM. They said they just renewed the oem software on the modules, which did not fix the problem. I used the tuner company EuroElites and dealt with Adam G., who is the Evotech North America representative.

What I'm confused about is if my ME unit was already coded for a 3.06 ratio, and I had a 3.27 ratio in the old unit which ran fine, which component was modified to get it running with the 3.27 gearset? Could it be possible that the sensors were reprogramed?

Is this part (A 210 350 44 39) the 3.27 gearset that will fit on a C32 diff?

Thanks for the help.
