hi I don't usually post here since I get to tune only my vehicles and its been successfully but I ran into this E40 with a hard code computer running this FIC1650 injectors cut and half and double the IFR, tuning has been easy no issues, my only concern is that when data log I seen Injector Duty cycle over 100% which its impossible due to having a triple pump Fore fuel system with 525 pumps and big injectors only making 19lbs of boost, fuel system stays over boost levels when peak RPM, there is no loss of boost or pressure what so ever but still shows IDC maxed out.
Now the only changed I did was the injectors and I went from a 2bar map to a 2.5 bar map, I did enter the correct linear and offset for the map and enter all the injector data provided even when go ahead and changed data with ID Data and Fuel injector clinic data and there was no difference just more tuning to do. I can post a recent log if that will help unless somebody knows how to fix the issue first.
thanks
