Doesn't work like that dude... ignition timing is all done in the map... you can log actual timing and timing pull with VCDS as part of diagnosing potential issues but the actual timing advance is set in the map which is adjusted on the fly based on what the ECU sees from other sensors (******* timing if knock is detected, IAT's too hot etc)
Cheers mate, I had the timing belt done just after I bought the car and have since noticed that sometimes when accelerating it seems to lag or stutter.
