2000 formula bolt on car, stock heads, stock cam, ls6 intake, lt headers, fipk, p&p tb and maf housing. i have the car running within a 2% error on the ve and maf tables but now i have a hanging idle issue when coasting. when coming to stop and i push the clutch in the car will hang around 1200 rpm untill i few sec after i come to a complete stop then it will drop to around 825. i raised the throttle cracker enable speed to 25mph and it did nothing, i zeroed out the throttle cracker table and it did nothing so i am lost with what else to try there. i also am having problems with the target idle speed. i changed it to 650 above 140* and did a entire write of the tune and it still idles at 825. i checked to see if the tb blade was closing all the way an it seems to be fine, i tried to adjust the idle screw on the tb and if i put it any lower the tb blade will just stick so i am assuming it is good. my tps reads 0% at idle. so i am at a loss at what to do next. i am new to tuning but the only things i can think of is my idle airfow is off since tuning the maf an ve or my idle spark is to high. i will post my tune and final log when i get home from work. any thoughts in the mean time?
