Anybody got any idea why the 06 Stoich AFR table is so much different on a 06 5.3 I have a copy of the table below anybody know why it is different than all the other AFR tables I have seen in other tunes.


14.68100 14.32168 13.97952 13.60797 13.25566 12.92114 12.56442 12.19048 11.83815 11.47339 11.13043 10.77895 10.42239 10.06388 9.70616 9.35160 9.00220

Would you change it to 14.681 all the way across,or leave it alone.

 

thats because its a flex fuel vehicle
stoich of 100% E85 is 9.0:1
stoich of 100% petrol is 14.7:1(14.68 is because of pcm resolution)
leave that table alone..no need to change it

 

My truck is not a flex-fuel engine at least it does not say so on the window sticker or by the VIN 8th didgit being a T

 

well..your Trucks OS is set up for it...just means that GM was lazy and reused the structure of an OS...possibly some of the vehicles with other sze engines are flex fuel...

eiter way..dont worry about the table..you wont need to change it

 

That being the case-What would you change the PE multiplier table too?
