Hey guys, I have just setup HP Tuners to my project LS1 swapped e36 bmw chassis. Saved a file of the current tune today. It has a 'startup idle tune' (Vats removed, Post cat o2's removed, STFT/LTFT disabled). The idle is setup perfectly 875rpm at operating temp, stays around stoich. Has a terrible time recovering from any throttle input upon letting off the gas. According to my wideband gauge, seems to be rich most of the time when on the throttle then badly lean upon letting off to the point where it dies. New to tuning looking to get some help/advice as to where to go from here?
Drivetrain: 2002 Camaro LS1 & T-56
241 cylinder heads
228/230 112LSA camshaft
LS2 intake manifold w/92mm cable throttlebody
Sikky swap headers (1-3/4" primaries w/ 3" collectors)
Stock LS1 injectors
5 wire truck style MAF
I have attached a file of the current tune if anyone would like to take a look. Any help would be much appreciated. Thanks.
