Hello All,
Working on a 2007 GT500 fully built with KB 3.6LC, KB dual 75MM TB, return style fuel system and ID1700 injectors. Problem I'm having is if car is revved above 5k rpm it goes into ETC FMEM on decel. Happens with free rev or on the dyno. When it goes ETC FMEM, it also goes into fuel cut and failsafe. I have worked on the DBW OLFF table and have everything dialed in pretty close. I was hoping that would resolve my issue, but no luck. I've had throttle body off several times and it seems to be operating smoothly. Even tried a new TB motor. TPS at KOEO is set to .68 volts like KB recommends and minimum throttle angle is set to 0. There isn't any wheel torque error when it happens either. I've attached the tune and a data log with a free rev above 5K showing the issue. What could be causing this issue? I've been racking my brain for weeks with no resolution. Any help will be greatly appreciated.
