Are you guys changing the stoich afr to 14.7 under the fueling tab or leaving it 14.108? Just curious to see what everyone is doing with these.

It should reflect the actual stoich value of the fuel being used.
The whole table reads 14.10840 from 0% to 100%.Quote:

question: 08 Lacrosse Super 5.3, E67 ECM I believe, I cant find a specific "Commanded A/F" table anywhere in the cal?
I changed the one labeled Stioch from 14.67 to 14.10 but my Commanded A/F Ratio did not change, it still reads 14.7:1 ?
using HP Tuners and scanning with Torque
Look at the EQ ratio, take that and divide it by your stoich to give you a commanded afr.Quote:

ditch the tourqe readings for commanded a/f verify the fuel youre using actually has 10%Ethanol. Use your hptuners scanner to tell you commanded a/f hi res to see whats going on, make sure you reset your fuel trims as well and see where everything settles.Quote:
