Alex182 Posted June 21, 2016 Report Share Posted June 21, 2016 Hi, we're currently tuning a RB25 Neo engine and got some trouble dialing in the fueling correctly. WOT Fueling is just fine but got trouble with consistent fueling on cruising (fluctuations) and tip in.The fueling map looks realy strange, but we've already double and triple checked the fuel pressure, deadtimes and even changed to new injectors and fuel pump.Anyone who'S got an idea what causes that kind of a curve in the fueling map?Many thanks in advance!BRAlex Quote Link to comment Share on other sites More sharing options...
Davidv Posted June 22, 2016 Report Share Posted June 22, 2016 Is that modeled fuel or traditional? Quote Link to comment Share on other sites More sharing options...

Simon Posted June 23, 2016 Report Share Posted June 23, 2016 I would check the injector dead times and the short pulse width adder table figures are correct for the injectors. Alex182 1 Quote Link to comment Share on other sites More sharing options...

Alex182 Posted June 24, 2016 Author Report Share Posted June 24, 2016 Thanks for the input. Indeed, I doublechecked dead times and tried different setups, but they seem to be spot on but I didn't do anything on the short pw adder yet. I'll check that, thanks a lot!
