Having a rough time getting this combination to idle without keeping 5+ percent of APP to keep it running. This is my first experience with Gen 5 torque based tuning. I have been logging the torque spark and lowering the VTT table to reduce the amount of spark it's pulling. It seems to be getting better, I have to hold less APP, but I can't let my foot off or it dies. I have also be working on the VVE table at the same time with my wideband. I was hoping by working both at once I could at least get this to the point it will idle and I can drive it around to work on the VVE table under load. I have dual widebands installed about 6" behind the stock O2 sensors. Only the even bank is being logged though.
L86 stock long block
BTR 220 camshaft
Long Tube headers
L86 intake and throttle body
L86 MAF and MAP sensors
Manual transmission
The computer "identifies" as a 2014 Corvette so I could start with a manual transmission OS. I started with a stock L86 VTT set of data and the LT1 VVE table. I have attached the last two tune iterations and the logs that correspond to those tunes (5.2 and 5.3).
I have not touched the Driver Demand table. Just messed with some of the idle rpm and torque based tables based on other threads on this forum.
Thanks for any suggestions!
