So, I loaded the PBD 93R tune this past Saturday. Due to the inclement weather and American football game I haven't had much road time to assess it. Initial thoughts are - car runs, shifts, drives even more smoothly/crisply than the 91-93 tune. The boost seems to kick in much earlier / more quickly. Definitely seems quicker by seat of pants.. Also, loading the tune only took about 6.5 minutes compared to the first tune, which took like 35 mins. (I would have hit the head and grabbed a beverage if I knew, haha)... If / when I ever buy a dragy I'll post some times.

first every dragy. I got the device Friday so the weather hasn't been that great. I was more trying to figure the dragy app than try a good run. I had the device just siting in my lap, not so good for a test. I forgot to put it in Sport mode as well. Once I get some better weather I'll try a couple of 'real' runs at a longer 'test area' to get full stats.

Few questions from a noob to this platform/Ethanol tuning
1. Why does E50 perform better than E85 on the ST? Figured higher octane would equate to larger gains
2. I understand running an E50 Tune requires mixing E85 with 91/93, but if running an E85 Tune do you just fill the tank with 100% undiluted E85?
3. Hoping to get a tune with ZFG once he’s back up and running. My research on his site shows I need the MPVI2 with 4 credits to get up and running. Does that lock me in to a single tune (91 Octane for example)? Is there an additional cost for gaining access to E85/E50 tunes? In a perfect world I’d like access to all three (I think).
Thanks for any insight. Hoping Adam gets sorted sooner than later, money burning a hole in my pocket.

When running E anything on any vehicle the limit ends up being fuel delivery capabilities... MOST stock fuel systems on DI cars dont seem to be able to run actual E85(they can obviously run it, but they cant take full advantage) because they run out of the ability to deliver fuel. E50 MIGHT be the limit of the stock fuel system on the ST and thus trying to run real E85 is a waste.
Ortiz Performance is Tuning the Exp ST, they are another reputable Ecboost tuner that follows all the EPA guidelines.
I am working with another tuner that uses SCT. He has some solid Ecoboost performance tunes for other platforms that use the Auto octane adjustment that will advance or retard the timing based off the octane values. More to follow on this later.
E85 from regular gas stations is blended with 87 octane . So running regular E85 without 93 won’t better than than 93 mixed with E85. You can get E85 that is blended with 93 or higher from performance venues but it was 5$-6$ per gallon before the pipeline was shutdown.

Lee, who runs Ortiz is also a great Ford parts guy, answers emails very quickly, ships parts quickly. All around great company for w/e it’s worth.

Thanks. Wondering why ZFG and other tuners offer an E85 tune instead of just E50

Order of Power on the ST most to least on different fuels using ZFG as the tuning source:
E85(Aftermarket Pump like XDI) - otherwise Stock
E50(Stock Pump) - slightly slower 0-60, maybe a 10th, but several 10ths in the 1/4, due to cooling.
E85(Stock Pump) - few 100ths faster than a 93 tune 0-60, but a little more than a 10th in the 1/4
93 Tuned
93 Stock(There is 10-15 HP to be had running 93 over 87 on the Stock Tune)
87 Stock
Also the 87-93 Gas is assuming E10. E0 will make even less power regardless of what grandpa says!

This kind of stuff is a big reason why the "flex fuel" sensors are the hot ticket for this kind of stuff... Run basically whatever from 87-93-e30-e50-e85... I dont think anybody has a flex fuel sensor kit out for us yet, hopefully though.
