Yeah I also see what your saying Ross, TBH a rough idle would not worry me, although would n't the lambda control the idling also ? Its not a rough idle just tho. Its general off boost driving. Ross

Right another thought. The AFM contains a temp sensor doesnt it? Havent seen one anywhere else on the inlet tract. Therefore the ECU thinks your driving in the Sahara desert and leans the mixture out?
Also surely closing the throttle will also lean it out as with the recirc you will sump measured air back into the engine to be meaured again?
Ben not with an atmos DV, hoping the leaning out of fuel could be sorted with mapping.

Ross hmmm I was under the impression mapping altered/corrected wether the car was on/off boost or when the TPS was above idling?? maybe the unichip can not do that? or is it when the car changes from open loop to closed?
