I've just put my Mk2 GTI back on the road. Its had a fair amount of work done from electrics to general age work.
I have had a reconditioned engine put in. Now though the engine is running well but on idle there is a little bumpiness/misfiring from the engine.
This seems to me that the car is not tuned and is firing ever so slightly off. I'm thinking that as the engine is a different one to before, the ECU would be setup differently to the previous engine.
Do I need to get a full dyno ECU remap or can I have a simple 'ECU reset' sort of thing to get the car running smoothly.
Anybody know any places to get the work done in London or surrounding area?
