Hi guys, after roaming around the forum i cant seem to get an anwser. so if you could help i would really apreciate.
Basicaly, i know that return less system have a fixed pressure fuel rail, so that ecu does change and adjust injector width instead, based on intake pressure.
my question is, if i where to boost trought that kind of set up, with the factory 1 bar sensor and no flash option to have a 2bar sensor. What could i do to get proper fueling.
as far as i can understand, lets say that maf rear a X amount of air at 2k rpm 15 psi of boost, then at 4 k rpm 0 psi of boost it would still read the same amount of air, BUT injector would need to be adjusted.
So, boost referenced fuel pump ? or is there some kind of tweak around this to get a proper afr
thanks again
