Hi, about to chuck this motor in the trash, please help. I have a 71 Demon with a 2012 5.7 with VVT and a 6.4 cam, long tube headers, 727 trans w/stock converter, 3,23 gears, MS3 hemi gold box with Tunerstudio software with autotune.
bought the car with all this already installed, so I don't know what settings came with the MS3.
I think I can figure out the timing and fuel, but the VVT settings are killing me.They seem to be the biggest problem at this time. Car will start cold with VVT in test mode, 100% duty, min-max set at 0/23 deg, but after it warms up it won't start again, slow to crank over and won't catch. when it does run, I take it off test and change the min/max to 0/60 deg and it runs ok with hold duty at 7.1% and steady VVT angle of about 49.1.
Per the MSextra manual I found the cam angle range while in test are 18.3 deg/100% duty and 70 deg/0% duty, any idea what all the VVT settings should be, including the hold/neutral duty and PID? First pic is setting that allow the car to start cold, second is settings after I get it to start and runs ok but won't restart after shutdown. Thanks in advance.
