The car is a 2016 Z06 with lingenfelter supercharger pulleys stock manifolds and cats, and an aftermarket cat back exhaust. Working off the Tuning School books MAF only procedure I was able to get the fuel in but the timing (torque management?) still is not happy and pulling lots of timing. If I am tuning in MAF only will the VE torque maps still pull the timing out like crazy? I attached a log of a WOT 2-4500 run along with the tune. I can start to tune the VE fuel if need be. I think my problems are from the virtual torque maps not being correct. The engine torque values look reasonable but the wheel torque values seem high. I put a knock monitor on and set the center freq to 5.6Khz and will do a run tomorrow and see if I can hear knock but I haven't heard anything yet. I will start the task of tuning the virtual torque maps tomorrow. I would really appreciate someone reviewing / critiquing my tune so I can learn. Thanks! EdGary Run30.hplEd_Tuning_5.hpt
