How HPT works - have I got it right?
I have two Audis that I'm anxious to start tuning ('12 A4 and '14 A6, both with the ZF 8-speed auto) but don't have the money to go "all-in" yet.
Am I correct in thinking that if I buy the MPVI2 interface but no credits I can:
* Download, view, and edit tune data from the ECUs in my cars
* Open and look at files created by others (I have a few .hpt files but when I try to open them VCM editor says "Please connect an MPVI2 interface")
But cannot flash anything back to the car?
And one more question: if I buy the credits to license a particular ECU in a particular car (the engine ECU in the A6 for example), I can reflash that ECU as many times as I want, right? I don't have to buy credits each time I make a change and want to reflash?
Thanks!
