APR ECU / TCU Tunes for the 4.0L 718 Boxster / Cayman / Spyder (GTS / GT4)

$2,500 is hard to swallow but these results are pretty fantastic for an NA car and APR produces a good product. I ran their tune on my Audi S5 for years with zero issues.
My main concern is the reliability of the 9A2 4.0L engine and the troubling number of engine failures emerging. Porsche has stepped up and replaced/repaired all of them so far, to my knowledge, but can't imagine they be as helpful if a tune was discovered. If I had more faith in the motor, I'd give this real consideration.

Arin@APR I looked this up on the APR site, and from the picture, it looks like the unit itself plugs into the OBDII port. Does it communicate to something with Bluetooth, like a phone app or a flash loader of some sort? If so, does the app store the OEM flash so you can swap that back to take the car to the dealer once a year to keep the PCNA warranty folks happy? If not, how do you keep a copy of the OEM digital info? How exactly does that work?
Thanks
Thanks

You visit an APR dealer and they install the software to your factory ECU via the OBDII port. We have a copy of every original file, which can be put back on by the dealer at any time.

@Arin@APR Can you explain the process to switch fuels from say 91 to 100 or E85? Is it because this generation of ECU is closed loop the entire load range that the ecu will simply adjust, no need to switch maps like in the old days of open loop high load tables?
Thanks in advance

The ECU needs to be reflashed to go from a pump fuel tune, to a race fuel or ethanol tune.
