I’m thinking injector flow to correct rich is to increase the injector flow rate.

For example the WBO2 is showing AFR’s averaging 12.4 with an injector flow rate of 22 lb/hr. After increasing the injector flow rate to 24 lb/hr the AFR’s are averaging 13.8.

Increasing the injector flow rate makes the computer “think” less fuel / smaller injector pulse width is needed.

I adjust the VE Table when the data log shows some AFR’s are Lean and some AFR’s are Rich.

Adjusting injector flow is course tuning and adjusting VE Table is fine tuning.

Most if not all 305 TPI engines had 19 lb injectors as original equipment.
