ECU remap - revert to standard tune if battery disconnected?
Discussion
crap, it's never simple is it?!
I fitted a cold air induction kit prior to getting my car remapped, it was subsequently off the road for a long period (battery disconnected, hence my question).
It's thrown a couple of engine warnings (running rich) which I was hoping related to too much air / fuel mixture.
Looks like I'll be fitting the standard airbox and taking back to VW then...

No, the part that is changed wont revert back to oem, however any variable parts of the ECU will reset to default values . . . . . a Porsche 911 /964 for example, uses various sensors to "optimise" the setup if the battery is disconnected for any period of time, with variances in the effectiveness of that adaptation depending on whether the car was driven or not whilst the ECU re learns.
If its throwing errors, get the car nice and warm, disconnect the battery for half an hour or so . . . . . . .reconnect, start the car and as quickly as possible take it for a drive, using full throttle where your able to.
Have you got any of the diagnostic codes out of it for the errors? . . . . . . .and did you remember to wipe all the DTC’s
