So, I am setting up my Ballenger AFR500 (old NGK Powerdex) for use with HPT. I know I can use the NGK PID, but I am wanting to make sure the offset is correct for use with E10 fuel so that if I setup AFR or Lamda error, it's actually correct.
The stock formula is V/.714 + 9. Should that 9 be 8.4 because of the E10 Stoichiometric value being .6 lower than E0 fuel?
