Larger Injectors adjust map

[Ollieh17]

Hi,

I have fitted larger injectors to my charade GTTI and it is running very rich and rough. I want to be able to drive the car to the tuners to have a proper map done. To be able to do this can the Det 3 mirror the standard map and make the adjustments to compensate for larger injectors, no changing ignition settings etc.

Any advice or recommendations?

If you have it in piggyback mode, you can just lower the global fueling all over the map. Otherwise, you can just just lower the fuel pressure.
