'7747 Commanded AFR vs BPW vs VE's

Guys,

I would like to bring my commanded PE AFR into line with what the WBO2 is showing. Currently the PE AFR tables are at 11:1 to give 12.8:1 at the WBO2.

Are the VE's independant of the commanded AFR calcs? ie., Can I adjust the BPW constant to bring the actual AFR closer to commanded AFR without having to remap the VE's??

TIA,
Ben.

The fuel calc for PE is based off your VE tables, which are based off bpw,

I would add fuel to your VE table in the high rpm/ high map areas to make your PE afr match your WB
