post this in the forced induction forum, there are guys running them in there. basically it modifies the MAF signal, so yes fueling will change but so will timing, also adaption will be fighting the changes at part throttle.
the threshold option on the ARC1-003 looks good, but it doesn't have the range of adjustability that the ARC2 has.
yeah its cable-throttle motronic, like 3.xx.
this sits between the ECU and the injectors so you can dial up whatever you want for fuel changes without affecting the load calculation (ie timing map isn't altered as the MAF reading is true), still have to work within the limits of adaption/fuel trim as mentioned in the article.
I suppose the trick is the TPS input....which could be taken off of the E-gas pedal, that's where my BCS picks it up from.
