I've pm'd and emailed a few about this, been playing with it this week.
I'm currently running a blend of 25% Ethanol to 93 Octane and my LNF likes it a bunch.
Had to trim the MAF freq about 4% leaner (no LNF stoich tables) to adjust for the positive LTFT shift. I've increased the midrange high load timing a few degrees and I'm at 18* up top even with 120* IAT2's in 99* ambient, no KR!
No midload/rpm KR and I used to see 2-3* most days same tables.
Injection window is 5.6 ms at 6k I'm told (thanks Term & Steddy!) and I'm seeing about 5.2 ms at 70* ambient, less as the air gets thinner.
Looks like I've gained about .4 sec on the 60-100 mph ricer runs in third.
MPG dropped 1 mpg on the average. I've got about 300 miles logged on this so far.
Next week I'll up it to 35% & check the injection window once again.
Running a PE of .88, but going to try .84 to see if it changes anything, maybe add more timing yet. I've read 25* advance is about it on an LSJ, so I'll keep that in mind. I really wish I could just run E85, but it's becoming obvious it won't make it with the DI window.
