View Full Version : Timing/AFR problem only when in manual mode T43

I'm experiencing a weird scenario that I can't quite figure out. When I have my car (09 cts-v) in manual mode at part throttle, I experience a rapid jump in timing and the AFR leans out completely. I'm thinking something in the tune is telling it to pull timing, because the values never go below my "minimum final timing" values. This does not happen in regular auto mode.

Now I believe this to be called Fast Torque Exit with hpt. Is this parameter in the tune somewhere?

Thanks for the help on this...I ended up just using Hp tuners to turn off fast torque exit, and it fixed it....

I have the same problem in almost all pulley E67 i tuned
the car is pulling timing when the torque increase
so i hope this table will be added to E67
