Took awhile, but I finally got everything setup for E85.
Some notes:
1) If you think you can syphon fuel out of a GT350, don't count on it. I tried every hose/tube I could muster and there must be an anti-syphon baffle or screen at the bottom of the filler neck, because despite my best efforts, I could not syphon fuel OUT of the fuel cell. I ended up idling the car well past "0 miles" on the range display.
2) I have some street logging to do and report back to Lund, but the difference is noticeable. Not crazy or night and day (and I try to be very honest with myself and not fall victim to placebo effects). I can tell a difference in both torque and sound. I also tend to monitor the AFR, Spark and Knock and the tune Lund provides definitely runs out additional timing in the lower RPM range (which is where the added torque comes from). The sound is different. As in, it doesn't sound as good (to me) as the 93 tune. The last 93 tune I finished with sounds very full and deep (some of you may notice the car sounds and feels a little different at full tank after fill up. I'm not sure if this is added static pressure from the fuel to the pump at full tank or if it's due to the computer/ecu re-learn that happens when you go from low fuel level to top off).
3) I've researched, but there's honestly not a lot of information out there beyond E85 locations (in terms of E85 content). I ran the car down as much as possible and filled with E85 from a Marathon station near my home. After several minutes of drawing out the old 93 in the fuel system and getting the car acclimated, the car settled on 77% ethanol content (using the NGauge gauge output that's a workaround I guess). I know there's wide standards for E85, so I'm guessing some stations get higher content than others (and probably varies at the same station depending on when they fill the tanks).
I have yet to run the full E85 tune, right now I'm still testing out the flex tune. I'll report back as to whether that "feels" any better. At some point I'll try to get this thing on a dyno and report back numbers.
I have ARH full system (with 2" primaries) and JLT CAI with the Lund Tunes loaded as well as Signature wheels (21 and 23 lbs) so this thing should put down some nice RWHP/RWTQ numbers.
