It doesn't matter what AFR is on the map, the NB O2 will keep the burn at 14.7 in closed loop no matter what is on the table, even while highly diluted, fuel economic exhaust recirc which only activates in closed loop.
Wondering if there's a way to fudge the front O2 to run leaner than stoich to save gas, no reason not to run lean catless anyways.

Assuming that his car doesn't have the Mods to the Open Loop Load Maps, or, maybe I am just getting to used to tuning IX's and doing that mod right from the get-go.

maybe if we can know the voltage of the nb at 15.5 afr (say x volts), we can put a simple electronic circuit between the nb and the ecu which will, when reading x volts, convert it to the voltage that the nb gives when reading 14.7
ofcourse the circuit will have to also offset the nb voltage when it's reading 14.7...
basically the circuit will have to switch the whole voltage vs afr curve...
what do u guys think??

here's mines....mods are still TBE, 720cc, invidia o2, and last but not least #65 pill please all comments welcome...i'm still in the early stages of tuning for boost @ 23psi so it's conservative in timing and fuel, what do u think of the wgdc table for a 65 pill is it ok?. advice is greatly appreciated..o almost forgot it's 91octane

Why so rich?
1* at peak torque?

Some cars you can only run 1*, mainly depending on boost. I would start leaning out your AFR and see how the car reacts, then start fine tuning the ign timing.
Looks like you right on track so far.
You should be able to run some more boost as well, 20-21psi is just starting on the 9's.
