2024 5.0 and Flex Fuel...

[EL5_Zero]

I'll let you guys know if the new 2024 will be E85 compatible, as soon as I get my hands on it. Supposedly, my '24 SCSB is schedule to arrive next week to CA. Even if it doesn't come "E85 ready" from factory, I'm hopping tuners will have access soon to see if they can turn on the Flex Fuel logic like they did on the mustangs.

I've got HPTuners, but the 24s are not supported... until someone sends in the PCM for VEhicle beta testing.

Guess here is FORD is finding out that Alcohol being a much better solvent than gasoline that the Alcohol may be doing more harm than good when the engine is in cylinder de-activation mode. Or in simpler terms Ford is seeing more cylinder wall scrubbing with Alcohol than Gasoline.

There is no fuel being injected into the cylinder when it’s deactivated, this sounds like a bunch of nonsense lol

I don’t think so for the 14th gen refresh but soon pretty much all DI engines will have GPF. I would think the 3.5 EB would require this first. GPF is for particulates, the 5.0’s DI system is newer and runs at a higher bar pressure than the EcoBoost so it should be a bit cleaner. My very anectodal comparison of tailpipes leads me to believe the 3.5 is much more sooty than the 5.0, 3.5 tailpipes are usually pretty black. Either way, I don’t think a particulate filter is something to worry about.

1. It's a lower compression engine. Less efficient burn.
2. Forced Induction engine will run richer AFRs.

Could explain that....

^Agree. I think (?) the EPA stuff on gasoline particulate filter requirements for model year 2027 and beyond is still in "proposed" stage in the Federal Register but won't be long before it's a Final Rule. Ironic that F150's (both gasser and HEV) and a '22 F250 with 7.3L gasser were used in EPA's particulate matter/GPF testing.

Interesting to me you mentioned the 'tailpipe soot test'. When I lived rural a few years ago, had a '16 Screw with 3.5EB DI-only. Ran like a scalded cat, I had very little short-trip driving. After spouse illness moved to small city, a change to mainly short-trip stop-and-go driving w/o getting to regular operating temp. Really poor drive routine for long term DI engine longevity. Traded for a '2018 Scab with 2.7EB DI/MPFI. The 'tailpipe test' difference was day and night, almost zero soot with the 2.7.

GPF's are claimed as being "generally" trouble-free (from Europe/China data) but I'm a bit of a Luddite on these, the idea of another 500+ deg. C. operating temp device on my vehicle doesn't thrill me. Never had a diesel truck with a DPF but learned to hate regen cycles on the Tier 3 utility tractor I had.

The future of IC engines is kind of a doom loop; DI adoption happened with gains in fuel economy and CO2 reduction but an increase in particulate matter. So now GPF introduction to reduce PM but with a real challenge to also NOT reduce fuel economy (backpressure, regen physics). Still haven't seen in print any concrete mitigation measures for brake pad/tire particulate matter - other than 'drive a featherweight EV once they are a reality'.

Unfortunately this is what I found while searching thru new 2024 owners manual…

Thanks for finding. Lots of significant changes going from the 2023 to 2024 F-150 models.

Someone posted the window sticker too and it definitely shows it's a gasoline only vehicle. My WS states it's FFV. I am curious about the change!

Did you guys see Jim's post on one of the FB f150 groups? He ordered a 2024 RCSB 5.0 4x4 off the Ford website after building it, like many of us have. He received it the other day, and it is NOT Flex fuel capable. Someone from a dealer searched his VIN for a build sheet and confirmed it is not a FFV. His User Manual specifies 87 or higher, but DO NOT USE E85. I really hope that's not the case on all 2024s.

Does anyone have any additional information on the topic?

How can I look up my build sheet to confirm if my truck will or will not have it?

They advertise E85 compatible when you build the truck....

Key word in that spec sheet from Ford Media website is "Preliminary". Everything I've seen recently - the '24 F150 OM, '24 F150 specs from Bodybuilder site (now in Ford Pro for some reason), and even '24 EPA Fuel Economy Guide - do not show the 5.0 liter as Flex Fuel, 87 octane min. only. Guess if you want a FFV PU you get a Silverado/Sierra with a 5.3 (or an Explorer with the 3.3).

I can’t find any change in the fuel pump or injectors, so a tuner will be able to simply turn it on like GM with the 6.2

Picked up my 2024 5.0 this morning and got these pics

Can the trucks be scanned, even though not tuned? Is it possible they are still setup for e85 but have this new filter some are talking about? Seems like Ford would do the least they would need to and certainly not change parts if they didn't have to.

This is a good question. Hey @VTR_16 can you sift through your manual (only if you have time or feel like it of course) and see if there is anything on a particulate filter in the maintenance section. There were rumors the 3.5 Eco and 5.0 might be coming equipped with a GPF but so far those are only rumors. Nothing from Ford but that is a maintenance item and would be called out in the maintenance section of the manual.

Yea man I’ll browse thru it and see what I can find
