Picked up a new 2022 F150 3.5 ecoboost lariat a couple weeks back and immediately installed the JB4. Truck is completely stock w/ 3.31 gears, 6.5ft bed and supercrew
1st time I filled up, put in an e30 blend and it was great, but having to figure out how much e85 and 91 to put in is always a pain, so I decided to start upping the E content until either the truck didnt run well or i was filling up with 100% e85 (only 70% ethanol around here). Well, this week i finally bumped it up to full e85 and from what I can tell, the truck is running great with it. High Pressure Fuel Pump dips down a little depending on gear/rpm/boost, but hasnt caused an issue yet. Running Map 5 as I figured out how the truck was running, and will start experimenting with Map 6 and 7.
Coming from an N54, I know the JB4 logging parameters and where they needed to be for that engine pretty well. Still working on figuring out the F150, so if someone has any insight on what safe levels on the fp_h, trims, etc are, im all ears. Assuming fp_h staying about 10 is solid like it was on the N54 and trims im assuming work the same (25 is 0, 25+ fuel added up to 50, 25- fuel removed down to 0) and something in the 25-35 range would mean the fuel system isnt being maxed out.
Overall, with about 400 miles now running straight e85, everything seems to be in line with where it needs to be. FWIW, I am in Colorado so at a higher elevation, and I know in the past on other platforms, this has allowed me to run more ethanol than those at lower elevations so your results may vary. I am underboosting by a few psi according to the ECU PSI vs DME BT comparison once you get up in the RPMs, but this is almost certainly due to the nature of the stock turbos.
In the coming weeks, I'll decide how stock I keep the truck (its my work truck), get the draggy set up and hopefully be getting on a dyno as well so I can get virtual dyno calibrated to monitor changes.
