Guys,

We need to take in consideration the 91 Chevron I use can use up to 10% of ethanol.

Stochiometric A/F would be then 14.1/1

I switched to Lambda with my Bosh O2 wideband and I'm at 0.88-0.89 at WOT... Which should be 12.5 AFR with E10 (91 Chevron)

Z06 is around 0.85-0.86 with the supercharger...

I read everywhere DI runs leaner but by how much ?.... My 2018 Mustang GT with the new dual injection system runs 11.5 AFR at WOT @6000-7500 rpm and around 12-12.5 before .... which is very rich...

Thanks
