thought would post on here as need some info and help.
just done a conversion into a mk3 golf using an AGU from a a3.
the ecu im using is an unlocked one from a mk4 golf.
drove it home fine yesterday with no issues. i disconnected the battery to do some wiring and when i started back up it started great but wont let me rev past 2500, and then the revs will drop to 1000 (idle speed)
i try and pull off but its not letting me move.
tried doing a throttle alignment using the door open technique (not sure if that works with mine due to it being a mk3)
is it just a case of getting someone who has vagcom to do a alignment on it? or is there other issues?
