2006 GTO tune check

[5ft24]

Can someone look at my log and tune? I have flex enabled, I am down to 15% ethanol, so close to plain pump 92. Just dropped enable RPM of PE and sped up PE ramp from 1.0 to 0.7, want to make sure I'm doing well. Did a Lambda error histogram as well, need to know how to apply those changes to the high MAF table as well.
internals all stock, 3" Magnaflow cat back competition system and Duspeed OTR CAI and Flex. M6 also.
Log was a fresh start with all fuel trims zeroed and WOT at the end thru 2nd gear and into 3rd, slight uphill incline.
Thanks

If you look at your chart, at 2800 rpm, you are wot and 101kpa, and running lean. You need to make the PE Enrichment 1.17 from 2500 up so you can correct the ve table and maf tables. Change the rpm delay to 0 and the ramp in to 2--that is faster, not the other way.

I'm not sure how E85 does on a NA engine versus a blower motor, but I had to add a bunch of fuel to my upper rpm's when I was using E. You might find that when you add a tank of E, that you are running lean at wot. I have two separate tunes.

Gotcha. Mis-read the little tip at the bottom of the window.
Modified it.
When I was on the Dyno with E75 or so a couple weeks ago, WOT was a little fat (0.81) or so. Then at the track last weekend, I hosed myself with too much timing. Went from 108.1 MPH down to 103... Backed off the timing for a max of 29 on E85. Ran it almost dry on the E85 and filled with 92... 14MPG when I drive 65 miles a day was a bit expensive... Especially since the one station here with E85 is 3.65/gallon...
I'll flash these changes after work and take another run and see where I'm at.
Thanks!

Yeah, changes at the track show up really quick. I went back to 93 and made some runs on Sunday. It was fat on the top end (a little bit) and I reduced fuel and slowed down .2 in the quarter. I guess it likes the fuel. There was a .5 second and 8mph difference in Ignite E85 and 93 octane. 93 being slower.

Quick run up after the changes...

Nice. You can see when you go wot, you are still a little lean if you want .906 lambda. Use the eq error to add fuel to your maf and pe table. You will have to smooth and interpolate several cells to get a smooth maf curve and ve.

[5ft24]

How did you set up your EQ error graph?
I followed a youtube vid and mine is a single row that just correlates to the MAF High table...

[Lakegoat]

If you are tuning the ve table, it needs to look like your ve table. I would tune the ve table first and then the maf. Don't log anything maf in channels when tuning the ve table.

NA standard comp LS engine do nothing with E85.

with a cam on pump they'll take 24/5 degrees timing. any more doesn't do anything. switching to E85 might see it take 29-30 degrees but with the LS head that wont gain any advantage. NA LS stock stuff I've done is lucky to pick up 10rwhp on E85.

big compression or boost is a totally different story though

On the Dyno, 10-11 is what I saw. I am planning on. An LSA blower in the future, as well as cam, intake and headers

So back to 92, Small trim to MAF at higher flow, think I have it nailed.

On the log in this previous post above, I am still seeing a brief lean spot going WOT
Any ideas?
