I have read that the existing AP can be used, it will need a software update (download) for the GENPU.

"We've been spending extensive time on the dyno, driving on the street, and we are having a few different calibrators test drive the cars on the Alpha AP calibations to verify the car is performing as expected. It is also entertaining when a professional calibrator says "Car requires two firm hands on the wheel for WOT operation". I cannot release any figures or graphs just yet, but the car is responding well thus far. The 2010 has slightly different ECU operations that the previous MS3 vehicles, we need to make sure the car performs as expected before we look into any releases. Please know that how ATR is used to modify calibrations may be slightly different due to the differing ECU operations. All said and done, starting with a base calibration will make things much easier.
I believe we may be able to update the current AP-MAZ-002 AccessPORTs to support these vehicles. I will confirm this with our engineering team. I am saying this as a heads up for those that would like to purchase the device and simply wait for a firmware update so the device recognizes the 2010 MS3. This would allow for immediate gratification once the 2010 MS3 AccessPORT and AccessTUNER software has been approved for release...you won't have to wait for shipping.
We still need to integrate some of the fancier features that we have for the previous models(FFS/LC, MAP-based boost tuning, etc.), but things are progressing well.
I am happy to address any questions you may have, for now I am just staying focused on doing what I can to help the R&D process so we can release the 2010 MS3 AccessPORT with confidence.

I have been waiting patiently but I want 300+ hp.
