g40 running!

[bbvw]

Hi people, could some one please give me some help.

I built my g40 and had a few mods done as i built it up but the thing is its not running rite at idle and splutters when driving, i know its over fueling but could this bad running just be down to ecu setup or could it be another fault???

Thanks Matt

what's the spec of the engine, what mods have you done to it?

[bbvw]

well its standard bottom end. Its got toothies, stage 4 charger, dewedged throttle flap, ported head, ported gt inlet and exhaust manifold, induction kit.

what chip and what injectors are in it?

there's a million things that could be causing overfuelling really, I'd start by looking at the blue temp sensor and the lambda probe.  Do you have a VAGCOM lead?

well i dont know what chip its got in the ecu, think its standard, that should still run it tho shouldnt it, even on idle? its got standard injectors. i havent got vag com no soz, want it tho!?
