Please help. I am unable to change the commanded A/F ratio. I am working on a 2011 Silverado and have disabled Closed loop as well as LTFT's. I have hacked all of the open loop tables, even those that I wouldn't normally mess with. Anyone know what I am missing? Help would be greatly appreciated. The commanded A/F ratio always reads 12.23. I have attached the most recent hacked up version of the tune.
Thanks.
