I just did the ROM dump. Maybe it's all in my head, but the car feels much better accelerating from a stop than it ever has. Really it feels better through all the gears (MTX) than it ever has. Did my car learn to be a piece of shit from the PO (or from me) or what?Point being when you start this process if you want baseline WOT pull logs (and you probably do) for comparison purposes make sure you give the car some time to re-learn after pulling the base ROM dump before you go do those pulls, or you're going to get numbers that are SIGNIFICANTLY down from where they should be. In addition while OVT notes that you need to drive the car for 20 or so miles before logging to send back to him after flashing a new ROM file I'll underline this -- the ECU's adaptive process is VERY material to performance so don't ignore that instruction!
Edit: When you say ROM dump, are you referring the first copy of the ecu that's made after linking the VIN Key and Device Key? That's the part I just finished, and it sounds like doing that resets the ecu to factory... ?
