Last summer I had my car with a 7mgte tuned and the car ran OK sometimes but i would get random misfires between 2500-3000 RPM. that made the car sluggish and hard to drive in 5 gear when just cruising. i did some research and found that the multiplex caused issues so i put a dh61 ignitor in it and made the coil setting changes in AEM. now the misfires seem to be much worse i can not even accelerate in 5 gear under 4000rpm. the runs very well and pull hard after 4000 rpm so I don't think their is a problem with the cam crank sensor. i looked at the timing map that the tuner made and it seemed very close to the stock map. I have attached my ems calibration file and a few log files. can anyone tell me why is causing this to happen. i just want to know if the problem is in the tune or if their is something wrong like a bad sensor or ground.
here is list of the mods i have: ported head, JE pistons 40 over, precision sc61 turbo, precision 680cc injectors, waalbro 255 fuel pump, front mount inter-cooler w/ 2.5in piping, 3in turbo back exhaust. my ems is using a 3.5bar map sensor, air temp sensor and the gm boost solenoid. EVANS 2012 was the calibration created by the tuner, The DH61 Install is the one I am running now its them same as Evans 2012 except for the coil setting for the dh61. the working map is the stock calibration for the car.
