If you can return it back do it, otherwise sell it. Don't touch your ECU with this crap cuz it will be deregulated, and the gains are negligible. There is no match between fuel, air, ignition etc...... That's because this piggyback thing controls only some engine parameters and there is no correct mixture.hi just bought a vafc2 for my ek9 but dont know how to set everything anyone can help or is there a sample setting for ek9?
I think you need to remap your ECUthx above and i already installed it but seems no good i think i am going to take it off, do i need to remap my ecu? if i take it off will everything goes back to standard?
