Greetings from Singapore! Will like to thanks everyone in this forum for contributing so much effort and time. Currently having YOM 2011 Audi Q7 3.0TFSI (272bhp) with Aisin 8speed triptronic and ECU 4L0910551 0070 Simos 8.3. Wondering will I be able to request for a tune to go with a bigger crank pulley of 203mm combine with stock supercharger pulley at 63.25mm having an increase pulley ratio of 3.209. Car now with K & N drop in fliter and will be looking at upgrading the cooling by adding a bigger supercharger heat exchanger. Will I also need the DSG tune for the transmission? Alternatively, I found an ECU that's for sale with ECU No 4L0910551P 0020. Can it be used as a spare just for remapping purposes?

Last but not least, will appreciate if you could advise what are the hardwares and cable require to be able to download the tunes and flash from home. Will be great if you can also give an indication on the gains from this tune or any that you can recommend. Thanks in advance.

Robowork,
I am not familiar on tuning and gather through the my research that the ECU in my car cannot be directly read or write by OBD2. Would you be kind enough to explain on how to go about reading the files from my car? Would I able to use the extra ECU 4L0910551P 0020 to be remapped instead of my car existing ECU? Thanks in advance!
