So I've had my 2013 SHO for 2 years and I'm a large fleet Tech so I have access to IDS. The things been trouble free so I really haven't done much to it to this point, but today after work I thought I'd check some modules for updates. The PCM had a pop from DG1A-12A650-AYC to the latest DG1A-12A650-AYD. Short of a TSB or SSM in Oasis telling you to update for a specific concern, as far as I know Ford doesn't arbitrarily just update modules just because a later update is available (Hyundai/Kia says if you find an update-do it no questions asked).
Is there a known reference that I can look at that will tell me what the new update addresses? I updated the PCM and drove it home today and really didn't notice any change, possibly shift apply is a bit faster (or possibly just my imagination wanting it to be). I also updated the RFA module which jumped from last digits AE to CB so it may have been a few behind. I just crossed the 60,000 mi point and plan to contact Livernois for one of their tunes. I also have a OBDlink MX sitting in front of me with FORscan loaded up ready to start exploring what I can tweek and look at at home. If anyone can shed some light on the factory updates, I'm curious. Kind of funny when you fix these things for a living you tend to gloss over stuff and just fix the car, where the hobby guys pick up on details about what you can play with.
Thanks,
Mark
