Yes. It’s better with pedal monster.
The hill assist control sucks a$$ on the 22…. It actually is worse when cold and going from R to D. Wasn’t nearly as intrusive on the 21 diesel.

So how does the newer big gas jobs do on down hills with a good sized load?
Some sort of trans braking?

It just downshifts to a lower gear and holds it there. Mine will do that in tow/haul mode

It's legit. I am happy with it. Removes some of the "deadness" of the factory DBW. I found a setting I liked and left it. Haven't touched it in months.
Neighbor put one in his 7.3 after driving mine a bit.
Would I spend the money on one? Dunno. This was in the truck when I bought it....

It does have aggressive trans braking when in tow/haul mode. If you are going down a steep grade and hit the brake for more than like 2 seconds it will downshift a few gears and rev up to 5k sometimes. Thats the only thing I dont care for about this truck. I just put it in manual mode let it sit about 3-4k rpms and then hit the brake when I need to slow down more. If I was towing in Colorado every day I would just get the diesel with the exhaust brake, but for 90 percent of where I tow the 7.3 is perfect for me.

Is all of pedal travel still usable, or does it just artificially shorten it like old 7.3 diesel tunes used to do?

Honestly, I don’t know the answer to that question. Maybe?

just shortens the travel to get to 100% as i understand it. just putting it in sport mode wakes up the take off pretty good.
Are you a bitch? I run Ignite E90 in my racecar and my wife stands around in the garage when it's running all the time with no complaints. And she will complain about anything.....
She does say it smells like the stove that was on her parents boat.
Pump E85 varies so much most racers don't use it anymore. They also fuck with the blend at the pumps in the winter and it's more like E70.
Valero is the only stations I see here that sells E85. Considering you use 30-35% more E85 than gasoline it's not priced low enough to justify the difference.
I’m talking about a drag racer. The 30% more volume used doesn’t make a difference in a 1/4 mile run but an effective 115 octane on an engine with 30 psi boost on top of high compression does matter. What you can’t do is plan on it being E85 & 115 octane and tune for that. Then stick sub par below expected ethanol content and subsequent lower octane in that engine and make a full throttle pass. It melts expensive aluminum parts and ruins a weekend at the track.

The 18 and newer coyote has direct and port injection so they can spray a lot of fuel. Like 1k horsepower worth. They also have a sensor that reads the alcohol content
I'm not saying they don't use E85 anymore I'm saying they are buying VP or one of the other brand race fuels E85.
Is pump E85 115 octane? The Ignite brand E90 I run is blended with race fuel and its only 114 octane.
I’m not a corn fueler anymore and wouldn’t know. That was just a reference to illustrate a number higher than race petrol not meant to be a real number. E85 is higher octane than 110 (if it’s real E85). I don’t know that I’d ever have a use for E85, I am surprised that it’s considered a “race fuel”. Dad ran top alcohol back in the day, 100% no blend. His car burned 1 gallon a second at WOT.
Edit. The highest output setting for my RZR hotrod engine is for E85. My engine is good for 10 more Hp on E85 than on 110
I run ethanol because methanol is illegal in SxS racing.
You could run E85 in the Bronco and turn up the boost.

What does a barrel of Ignite cost?
Talked to a few people that have and have had 7.3s and everybody always mentions the transmissions but nothing in tremendous detail... What exactly is the quirk? what I have seen in this thread is still a bit inconclusive... so far there are mega downshifts in tow haul and constantly searching for gears. Are there any problems with durability?
Will be looking in a few years to replace my 06 chevy 3500 8.1 6spd Alliison once it nears 200k with another large displacement gasser and have pondered the 6.8 or 7.3 in an F350.

My three complaints with the transmission.
1 - downshifts when towing suck. Ford seems to think the 7.3 has the same compression as the 6.7, and therefore it has a lot of compression braking. It doesn't. The crazy downshifts just make noise.. and then the transmission seems to not want to shift back up until USPS delivers permission to do so.
2 - Adaptive learning takes it from good shifting to akward shifting. Fortunately, it's easy to reset and freeze.
3 - I absolutely despise 3rd gear tuning at low speeds. Both my trucks would stay in 3rd going up my driveway rather than shifting to 2nd... about 1/2 way up, both trucks would lose about 50% RPM's and then bounce back... It only happens in 3rd for me... It's annoying AF.
I pay $610 a barrel from the local race fuel dealer. As a bonus he delivers them to my work for free.
^ this is also my experience
I hate the way these dorque management systems are programmed to shift. My 6.8/10R100 truck, like Rockota mentioned. Wants to be in 3rd gear and stay in 3rd gear. It’s got 3.31 gears which was dumb for a truck that’s going to spend 100% of its life going up and down mountains in canyon lands New Mexico.
I drive with it in tow/haul at all times to get it to where it will shift down to second by itself but I still have to floor it when it’s bogging down in 3rd to get it to shift to second. 1st gear still isn’t low/slow enough for 3.31 gears and just 285/70/17’s. If it shifts like I want it to it feels plenty powerful. But it feels like every other underpowered gasser 3/4 ton (6.0 GM or 6.2 Ford) when you just leave it in regular drive and let it shift itself

Unloaded, my 2020 refuses to use 2nd gear 95% of the time. Doesnt matter how gentle on throttle I am.
Also decelerating to a stop sign, if i roll it too slow, It will downshift from 3 to 1 and it kind of feels like shifting old zf into granny and letting clutch out without rev matching. If i roll thru kind of fast it will stay and lug from 3rd.
Im very happy with the torque and part throttle grunt below 2000 rpm
Also when trying to get thru mud, it wont start out in M2 like the 6r140 used to to get decent wheel speed, and with advance trac off it will still derate completely and go back to idle with foot on floor.
I think it boils down to I would be much happier with 6R140
I always like the old stuff when the new stuff is the hot shit. I liked my 5R110 the whole time. I like the 6R140. We’ll see if I “like” the 10 speed when it’s the old shit. I had a 5.0 10R80 F150 right after having a 5.0 6R80 and I preferred the 6 speed to the 10 speed at the time.

It is here. E85 I get regularly for 2.50-2.65, while e10 93 is 399-4.29.
I just checked gas buddy and it's as low as 2.45 right now locally.
Even with absolutely no effort to tune for efficiency, I get 10mpg beating the crap out of it the entire time, pump e85 costs less for me.
For your average "make junk go fast" guy pump e85 is still f'n awesome. Would I trust pump e85 on a $50k race engine... Lol, no.

It's a 2001 ranger with an explorer pushrod 5.0 and a turbo, no real elevation in Wisconsin.
Turbo five oh, perfect use case for E. Is it even drive able on pump gas?
