E85 AFR's

Hi,
I have searched the forum and googled with no luck for E85 numbers.
Is there a EFI Live E85 conversion how to I missed.

2004 HSV Clubsport LS1 12225074......................STD.........E85
{B3601} Ratio of Air to Fuel for Stoichiometry......14.63.......9.760
{B3606} Maximum Enrichment...........................12.947.....7. 515
{B3607} Open Loop Lean Limit (Idle)..................14.629.....9.700

Are my E85 numbers in the ball park or what do I change or leave.
This is a LS1 turbo straight E85.

If you use EQR units then stoich is 1.0000, idle is 1.000, NA PE is 1.175, boost PE is 1.25... regardless of fuel being run.

Sorry for the dumb question. But I'm in the middle of switching to an E85 only tune. If I change over to EQR on 93 oct then all my PE settings get converted as you say ~ 1.25. Then once I fill the tank with ethanol blend all I need to do is change my B3601 to 10.3 or so for E75 and I'm good to go?

Yes.

Change to your current stoich. You should go to a P59 ECM and add a sensor to avoid the changing of calibrations.
