Where to set Stoich for E10 in HPTuners

I'd like to set my Stoich AFR in HPTuners and living in Jersey we are "up to" E10 for pump gas. I know the table that has to be updated and have included it here below, the far left cell gets updated but do I have to update anything to the right of it? Also, for anyone that is doing the same, are you just setting Stoich to 14.137 or going a little bit higher like 14.25 or 14.3 because it is "up to" E10. I know this is being a little picky but so be it...Thanks in advance...

I believe you are right and only the first cell is referenced by the computer, I just played it safe and updated the entire row though, it doesn't hurt.

Your best bet is to just split the difference and set the stoich to 14.4.

Thanks, this then begs the question, what are all the other cells to the right in that table there for.


As for a WOT target with E10, I have seen the 11.9-12.0 range mentioned for an N/A vehicle as opposed to the 12.4-12-6 based on E0 so I am assuming a split the difference target would be 12.2ish.

the other parameters to the right are for vehicles that have flex fuel option enabled,, the camaro OS is not a flex fuel file,, but it shares many tables with many gm gen4 engines that do have flex fuel
