Hi gang, I recently purchased 2017 A5 Cabrio 2.0T quattro 2.0 TFSI. I have been tuning GM LS based engines for some time with HP Tuners. I have confirmed with HP tuners that they support my vehicle and am awaiting my upgraded tuning interface which I ordered the other day. What I can't seem to find is an overall guide to the VW /Bosch ECU OS or specific quirks of tuning the ECU / Trans controller.

Similar to items like:

Which I've read cover to cover several times (I know its not GM specific)
