Replacing Port Injectors on a 2022 F150 3.5 Ecoboost

[Csu87]

This week I swapped in some ID 1050 port injectors to run straight e85 on my F150. I watched several videos for previous gen trucks, didnt see any for the current gen engine, and its pretty straight forward on those. However, it seems for the current gen, they have added a bunch of items that I didnt see in any of the videos I watched, so instead of the next guy struggling to find everything that is keeping the manifold from coming out, I took some pics of what needs to be removed. Unfortunately, I didnt think of doing a step by step removal, so I only have pics of everything once its back together.

Before starting, pull the 30amp fuel pump fuse and let the truck run out of fuel.

I am pretty sure all bolts were 8mm. Cant remember if I used a 7mm on anything other than the intake hose clamps.

This 1st pic shows the 8 bolt locations (pink)(8mm). The 2 in the back are a little hard to get to, and youll have to pull the cables/hoses out of the way to get to them.

This pic also shows all the push in style cable tie locations. I had to cut all the ties to get the cables off the manifold, but once I had the manifold out, I was able to clean up the push in mount location, and use a standard zip tie to secure everything back down.

In Blue is a cable and hose that need to come off. they are tight, but if you cut the rest of the ties off, you are able to slide them off the manifold.

In Green is another clip that slides up to remove.

Another pic of the cable tie locations

This pic shows 2 hose clamps mounts (Purple) that need to be pulled off. They are plastic push in style mounts that push in to the side of the manifold. A PITA to get them out, but i was able to do it with a screwdriver without damaging them too bad.

In green, this mount needs to be unbolted (8mm) from the manifold and sensor unplugged.

This pic shows the mounts that the Hoses from above push in to the side of (Purple). and The 8mm Bolt for the sensor mount (red) from the last pic.

Also shows a hose (green) that needs to come off. It has 2 quick disconnects. Disconnect the one to the left 1st, then you can get the one off the manifold and pull the hose out.

In White, you need to remove the 8mm bolt. You wont be able to remove the pipe before getting the manifold loose and you will need to remove the pipe as youre pulling the manifold out.

The Blue sensor needs to be unplugged.

The Yellow arrow is pointing to another cable tie push in mount that needs to be cut.

Top view of the last pic's area. Ignore my ghetto rigged boost/bov hose configuration. Will be cleaning that up.

The cable highlighted in Yellow needs to slide off the top of the manifold. Once I had the manifold loose and everything disconnected, I was able to push the manifold back in to the engine bay and slide this cable off. It is tight but doable.

Obviously disconnect the intake pipe.

Once you get that manifold off, youre ready for the injectors.

Disconnect the Quick Disconnect fuel line (Green). Will be some fuel in there, so have a towel handy.

Disconnect the sensor (Yellow)

Unbolt both manifolds (8mm Purple)

You will have to remove both manifolds together. That hose in red isnt really flexible to do one, then the other. I removed injectors while manifolds were still in the engine bay. If you are smart, you will place a towel under them so nothing drops down in to the middle of the engine. I was not that smart.

For me, it took me about 2-2.5 hrs to get it taken apart and back together. A lot of that was figuring out what else was keeping the manifold from coming off or getting stuck.

Hope this helps the next guy.

Where the injectors the only thing you installed to run straight e85?? Also who did your tuning?

Thanks

Do you need a specialized tool to disconnect the fuel lines?
I'm here in my garage about to dive into this project and I was rereading your instructions and I just saw that. Please advise.
Also I cannot find a diagram online or in my truck showing which 30 amp fuse is for the fuel pump.

 

[Suns_PSD]

This job sort of sucked honestly. Some mods are fun to install, this one wasn't!

I'll burn out this tank of 93 Octane and fill up with E85 next time and report back.

I'll start a new thread in about 1 week and give a full update on this mod.

What I can tell you is that so far (about 200 miles) my mpg has only dropped 16% (with several acceleration pulls thrown in there) where-as my fuel costs from Super have dropped exactly 40%.

At this time, I'm probably closer to E70-E75 just because there was about 3 gallons residual Super in the tank. Because the fuel is not a true E85 I've limited the pulls to about 2/3 throttle and about 5-8 seconds. Once I get the next tank of E85 in there, I'll run it a bit harder for longer.

That's a pretty substantial cost savings with not such a large mpg drop. It looks like I can still comfortably get 400 miles per tank which is great. I had a flex fuel Corvette years ago and I'd have to start looking for E85 at about 120 miles, which frankly sucked.

The truck hauls *ss and feels a ton lighter I swear. You'd never know it has those gosh awful heavy towing tires combined with 22" wheels. I can't even imagine what Tank's 2wd light tire/ wheel 1000 rwhp beast must run like.

I had swapped the tune at a gas station and topped off with E85 and the moment the E85 hit the motor at a stop light about 3-5 minutes later the engine was rougher idling. Not horrible, but quite noticeable to me at first. It might have been a transient situation related to a mix still being in there, as I never noticed it again.

In addition, I have a 30 minute commute through the rolling TX Hill country and in the past the eco mode seemed to get worse economy as the motor struggled a bit on the long low grades. This morning I tested the Eco mode and I guess now that I have ~ 560 rwhp it pulled Eco effortlessly. Not certain that would result in improved economy or not. I'd certainly use Eco mode if I was flatland driving, like say driving from Austin to Destin, FL for a beach trip.

Also, I spent about 30 miles in Sport mode. With the other set up Sport mode made such a huge difference in acceleration from a roll, but it's much less noticeably now with this power. It's just not necessary unless you are racing or something as acceleration is astounding in normal mode.

I'll share more info as my experience grows. I'm nearly due for an oil change and I'm quite eager to see in the future how that affects my oil next time around.

The one week update:

So driving mixed style but definitely with some 'pulls' thrown in, the truck now gets 14-14.4 mpg on the E85. This sort of driving would net about 17.5-17.8 mpg on SuperUnleaded. This is mostly driving cautiously but maybe giving it a good hard acceleration pull a few times per day. Also worth noting is that it's a LOT faster when doing this on the E85. In 2wd, traction can be quite the issue up to about 40 mph on the E85 where-as I had no such problem on the SuperUnleaded (also tuned).

Driving really nice I averaged 18.4 mpg on Super and the same driving style on E85 averages 15.1 mpg

So my MPG loss is from 18-20%, while saving 40-42% on fuel costs going from Super to the E85. I'm going to assume the inside of the motor will clean out (on my flex fuel Corvette the motor stayed like new inside), the next set of spark plugs will stay cleaner (but maybe the electrode tip will burn away sooner?) and my motor oil next time around should stay cleaner as well.

So far getting E85 is zero problem as there are 2 stations right by my office but I need to familiarize myself with other options. Maybe an app or the like to locate all E85 stations? I can still go around 400 miles on a tank of fuel, which is more than enough.

I mentioned in my first post that the motor felt rougher when the E85 first hit but that has went away. It purrs, but the tone is raspier and more aggressive, but it's subtle.

Overall I'm very pleased with the mod but it's such a shame that Ford doesn't build these motors flex fuel like GM's come stock. That's a huge advantage as the tuning can auto adjust based on current ethanol percent as stock the injectors are sized correctly and there is a factory installed sensor that detects ethanol in GMs. Obviously being Forced Induction, the Eco-boost/ Powerboost platforms could gain way more power than the GM's however.

I drive quite a bit and in fact did over 400 miles over the weekend, most towing an RV.

Here are my general thoughts in no particular order on my E85 conversion:

1) The tuner (Livernois) says that they have to increase injected fuel quantity 30% on the E85 to make up for the lower energy density compared to gasoline. But even with the extra power, which I definitely am enjoying, my mpg drop from premium Super Unleaded is only 20%. It's my opinion that the motor is considerably more efficient on E85. Similar to how the mpg of these trucks can improve when moving to Super from regular unleaded. Not only are you getting 105 octane on E85 but you also get the cooling effect of all of that fuel. Together these effects allow more timing, more boost & more power and probably allow each BTU to propel your truck further.
2) Fuel costs: I drive by 2 E85 stations (HEB) daily and as of yesterday E85 cost $1.68/ gallon whereas Super at the same station is $2.98. Another way to look at it is at these rates, over 100K miles, I'd save $4,555 in fuel costs on the E85, while having much more acceleration. Realistically I'll run this truck to around 300K total miles. Sometimes I feel like it's the early aughts. My fuel cost about a $1.7/ gallon and my rig gets 14 mpg. Except my truck now is luxurious and absolutely hauls *ss in a way those trucks never could.
3) I find turbocharged gas engines are horribly inefficient while towing a large RV and this hasn't changed. I've towed my RV on Super, I've now towed it on E85. On the E85 I seemed to only loose about 11% efficiency. I averaged 7.0 mpg on E85 and average 7.5-8.2 mpg on Super. BTW I'm selling this RV and buying a collapsible unit and mpg is a big reason why. I did use an app to make certain I could keep her fed on E85 but had the ability to download a non E85 tune in a pinch. I had to buy E85 at high dollar amounts down on the TX coast and cost was similar to regular unleaded.
4) I have 4 tunes for the new big injectors: E85 race big injectors, E85 tow big injectors, Big injector 91 octane race, Big injector 89 octane tow. If I headed out on a big cross country RV trip I'd consider swapping back to just Super (same big injectors, just a tune swap) so that I didn't have to mess with it while traveling. For towing this past weekend, I ran the E85 big injector tow tune. It was clearly way slower than the E85 race tune but it was plenty adequate for towing the RV and I went up all the rolling hills in 8th gear with no downshifts maintaining 64 mph most of the time.

My thoughts are: if you have E85 available locally and it's at a good price, this is a very worthwhile mod. These turbocharged engines respond REALLY well to this mod. Basically, you can buy race fuel at the pump at a bargain price. The politics of E85 are probably stupid, but hey, don't hate the player, hate the game.

 

[Riddick]

Yes, E-85 will definitely make more power since you can really bump up the timing. It will keep the tops of your pistons and combustion chambers clean as you mentioned. If your running E-85 full time make sure you do frequent oil changes and make sure the oil is getting hot on your drives. When the ethanol mixes with your oil it will turn it milky fast and start to gel up in the bottom of your pan. Enjoy your new found power.

 

[JCsTruck]

You might want to reconsider 300k on E85.

 

[Suns_PSD]

I wasn't aware of this fuel dilution issue and there are some other opinions online, including some oil analysis showing no increase in oil degradation compared to gasoline oil analysis.

It appears that really short duty cycles are particularly bad while running E85. Livernois should warn people of this imo to determine if they are good candidates for E85. The video up above was from a car driven 1.2 miles, 2x per day; which is really hard on any motor.

This isn't an issue for me. I live a bit in the country, and my shortest commute is 30 minutes daily and 45+ minutes per drive is pretty common for me. It's also very hot in TX about 5 months of the year.

That said, I will run Blackstone oil analysis on my next oil change (just changed last night) at 75% of the full interval and report back.

Thanks for making me aware.

Fuel is dropping all around due to to the soft economy but I just paid $1.39/ gallon for E85 this morning.

I was at 70 miles till empty, and it cost $34 to fill up my truck this morning on E85. That's crazy!

 

[JCsTruck]

Wow, wish I could pay $34 to fill my tank. I pay $3.99/gal for 93 here.

 

[Suns_PSD]

I'm pretty sold on the E85 conversion, and frankly the turbo charged F150 motors over the 5.0.

Here are some interesting dyno numbers I found online:

The 5.0 with a stage 1 Whipple costs a few grand and makes about 531 rwhp/ 436 rwhtq. It requires Super Unleaded and I've NEVER known of a Supercharged motor that got decent mpg and they aren't that reliable either.

A 3.5 EB (couldn't locate numbers for the PB) on one dyno by MPT (I think it was a bit of a generous dyno going off the high stock numbers) did 392 rwhp stock on 93 octane, 492 tuned & 591 rhp/ 627 rwtq on an E85 tune.

My lifted Limited F150 only gets about 13.5- 14mpg on the E85 tune, but the fact that it can make so much power, reliably, with about $1200 in total mods, and importantly very low fueling costs, if you like power, why would you buy the 5.0 Whipple combo? Just doesn't make sense.

I've learned a few things about E85:

1) the price is highly volatile. I've seen it go from $1.39 to 1.99 at the exact same pump, on the same day, 2x now! Both are pretty cheap of course but if I'm below half a tank I always refill now if it's a day that I see it being low.
2) E85 is not appropriate for cold weather. I'm in Central TX, so not an issue overall, but they never mentioned this to me. At only 30 degrees, it struggles to start when left outside. I had no idea and could have been screwed if I took the truck to the mountains as no one even mentioned this.

Overall, would do again. I'd say if you live in the South or West, a PB or Ecoboost with injectors and a tune is a +500hp daily driver for about $1500, that's also cheap to fuel. What other mod gives you about 1 hp/ $10 AND lowers your fuel cost? Heck of a deal!

I am very tempted.
I would let livernois know about the hard starts. I’ve been running a 6.2 gen6 Camaro on e85 for almost ten years now. Myself and others have been able to get them to start up pretty well in teens by playing with things in the tune. Our pump goes to e60 in the winter, fyi.
But yeah Not sure if livernois got it all or not yet. They’re in Michigan so I don’t doubt they’d be able to get the most out of it. Might be worth an ask
