Looking for your recommendations on if you change the B3671 Stoich AFR from the GM scale to a straight number such as 14.2 for those of us who have somewhere between E7 and E10?
What advantages does this have?
The vehicle does not have a flex fuel sensor but I assume you leave B0178 Flex Fuel option as "Yes" and B0178 as "Calculated" and it should use LFTF's????
It would seem that with 14.2 is across the board the LFTS's would not matter as it would always command 14.2?
Is this a better process than the PCM trying to use the different Stoich values in the factory setup?
Thanks in advance..
