I don't think that would have done it in this case.

I had previously changed the bin stoich AFR value to 14.13, and was having the exact same issue.
Closed loop BLM#'s saying richer than stoich(contrary to wideband), PCM pulling fuel and going lean.
I could force open loop and get it to run fine and maintain whatever AFR commanded in tables.
Anywho tried that in March. http://www.gearhead-efi.com/Fuel-Inj...oich-14-13-AFR

Stock injectors ~61lb/hr, but increase the pressure to 15psi and they're more like ~71lb/hr.
61*sqrt(15/11) = 71.23
So changing the injector flow rate from 61 to 71 was it. One little setting.

Changing stoich AFR in the bin is a PITA, have to change all the other values/tables too.
Easier to just leave it @ 14.7 and just calculate using stoich.
Pretty sure that's how the code works behind the scenes?

I may say or type 14.7, but my brain is thinking 1.0.

All I know is this thing runs the way it's supposed to now, and the PCM is friends with the BLM#'s.
