Gotta love the 6 SD accuracy of the calibration in these GM OS's.

If there is a table in the OS for stoich values, and you want to change it, simply change the first value - the 0% value. And optionally the second value. Why ? Have seen GM OS's (the ones with the tables) show the ethanol content as 3%, so setting the second value (6.25% ?) to your chosen stoichiometric AFR ensures that if there is some offset built (maybe as there is so much E in fuels these days) that it potentially has no influence.

Some OS' have only one value.
{B3601} (OS 12212156) is stuck to whatever you think you fuel will be.
There is no way for the PCM to change EQ1 for % of Ethanol.
I have read a few posts where some people have supposedly found away
around this with the older OS' but they offered no details.

Correct. The stoich number needs to be changed in all of them to do this simply. The only OS's that use % ethanol are the flex fuel OS's with flex fuel enabled.

EFILive imposed limit is 10:1, but it allows lower numbers it seems with a "red" border on the cell which I guess means "beware".

Have made this stoich change on later OS's with positive results.

Sorry I thought you meant you had the table in 12212156. Just took a look at that with its single stoich number.

Understatement
Look at the big picture. I use OSID 12611134 commonly and stoich is 14.569824 across the table. I am in a E10 area. Just correcting that makes the cars run better as if it was in an E0 area. Then do a like adjusting for the E10 in the EQ table and the PE table and WOW.
Customers seem to be very happy with just these adjustments.

Great to hear! Yes its is unforunate that GM chooses not to leverage the potential of E10 even in their flex fuel vehicles. Leaving E10 as for E0.

What is 12611134 from?

Northstar with a blower.

If you knew me that would be a no brainer. I am one of the Northstar Guys, but I have started to step back from them and work with the other GM engines.
I am sooooooooooooooooo much happier

Did you work with Dave Hill?

COS3 or COS5 is easier .
Doesn't EFI University teach this in their EFILive courses ?

I am from the northwest mountains, R U maken funnys bout ma skoulen. I only learned to read and write a few years tago. I aint gonna go ta no skoul nohow noway, it tukma tree yeas ta learn ha ta go on da intranote. A unavarsity is a skouls write? Ah kinda like EFILive cause u can luk at da pretty pictures. Ah wish a could draw like dat, Den ah might gonna get me real rich. Like Mr Paul. mr.prick an mr.ross told ma dat mr paul was da owner of da intranote an I baleave dem dudes. whats holden crazy anaways? a pliace were ya hold crazzie thangs. I got ma a fu tuns from thare 1nc and I liked da nice pictures ta louk at. Da they call it download cuz its frum downunda? I culd go thare if in it was fa free. Ah noes bout alcohol cuz I live in da mountains. I caint baleave ya all dodnt knows bout makin alcohol an puttin it in a automobile, evens ah knows bout dat. Did ah tell ya I live in da mountains? Ah caint rememba.
