TunerPro E85 WOT too Rich

[Metal Health]

First tank of E85 comped the pte 1200cc down to 736cc (Tunerpro), Idle o2 bouncing around good, WOT(.95v)bucks, o2s way rich cant even get into boost.

So I try from the other side, comped to 1100cc. idle is way lean, o2 not coming off 0.03-0.05v do WOT car pulls way hard 0 knock o2 (.90-93v)

Stock fuel pressure
2g mass

Can anyone put this together?
I would like the cc to be correct as in the formula, I came out with 1200/804cc for the global, just WOT car bucks in richness.

Get the proper dead times, and start the global around 900, targeting 11:1 in all boost load rows. Then adjust the global until you see 11:1.

Yeah 900 is about right for this time of year, you should have E70 now because of the weather. In the summer you'll need to move it down to about 800. Have you touched the fuel map yet? Stock at wot is like 9.5:1 You need to be 11-12:1 on the gas scale for E85.

Forgot all about the fuel map. Donnie posted 11:1 across boost rows, is there more of a mathematical formula to this?

 

[bastarddsm]

yeah, put 11:1 in the boxes.

 

[donniekak]

11:1 is an arbitrary number. I use it because a little lean won't melt anything, and a little rich won't break up. Keeping the afrs steady across all rpms, and boost pressures gives a constant to tune for while calibrating injectors, or a maf.

Goodstuff! Let you know how it goes.

Afr table:
1-6 are 11.5
6-12 are 13.5

Car drives, my o2s at idle are ok and wot car boosts pretty good. Thanks for the starting point guys.
