E10 and E85 equivlant to gas AFR graph...

Can anyone make a graph that shows what e10 and e85 AFR's would be equivalent to in gas....

if someone does make the graph could u please start the gas AFR @ 11.0 AFR and work ur way up to 13.5 AFR in .5 AFR incraments....

thanks...

Great program, I run it on computers that I dont use daily (my laptop has MS Office 07 Ultimate, yay living 30min from microsoft in seattle) and if I build a PC for someone who doesnt have Office yet. Pretty much same feature set, some are developed more than Office.

Does OO support the new xml formats, like .docx, .xlsx, and .pptx? I would assume it does by now, I havent played with OO in a while and havent tried to open one of those.

So if one can only get E10 in the area and run OLSD, the car would run lean, right?

Does anyone have the ability to add AVGAS (100 low lead airplane fuel) to the spreadsheet? Is the lead content low enough to not hurt my O2 sensors..?

mr.prick

If you use AFR and change {B3601} or {B3671} for E10 the PID expression for WBO2 will need to be changed as well.
If your WBO2 converts Lambda1 to 14.7AFR and
{B3601} or {B3671} is 14.1AFR you will think AFR is 0.6 lean but in fact you are not.

Avoid this by taking WBO2 Lambda or EQ and convert it to AFR by taking the value of {B3601} or {B3671} and multiplying it by WBO2 Lambda or
divide the value of {B3601} or {B3671} by WBO2 EQ.
This will give you the proper AFR value that corresponds with EQ1 in {B3601} or {B3671}.

If you know what the stoich ratio is let me know & I will add it.
Any lead in the fuel will slowly degrade the sensor unfortunately. For this reason I always keep spares on hand.
