2.7L vs 2.3L Ford Performance Calibration Tune on Bronco -- Dragy Acceleration Results & Comparison

[Billnchristy]

Got mine completed a few days ago, 2022 OBX 2 door 2.7.

He isnt wrong about jumping off the line. In fact, its a little unnerving the first few times. First time I did it going about 10mph and went full throttle, the front end lifted up so much that the steering was loose. The wheels were obviously not off the ground, but the front lifted up enough that the steering wheel was going left and right and the wheels were not getting good traction. Not sure if 4 wheel would be the same since a longer wheel base, but just be aware.

I'd like to hear from other 2 door owners to make sure Im not crazy. Several times I have done this, and its a bit surprising.

I have a thread in the suspension section about that. Yes, she gets squirrely when you hammer down.

Basically 7.0 0-60 stock
6.3 or so with tune.

Was that the 2.3 or the 2.7?

Is this video comparing a tuned 2.3 versus a stock 2.7 or also a tuned 2.7?

2.7
Edit: sorry was just 2.7 stock vs tune

Yeah, it does for sure. Just gotta keep it in mind I guess.

Thanks...

Makes sense after I dug a bit deeper...

I was hoping for wheelies but this sounds like a nice improvement

Doesn't the stock tune significantly limit boost in 1st gear?

I remember reading somewhere that a second gear launch will net you a faster 0-60 on the stock tune.

That would add up to me with what's shown and being discussed here.

That is right, massive torque management in first gear, which actually had me considering the 2.3L in my new Bronco because it didn't sound like it was much slower. After seeing this thread, I'm glad my 2.7 just got scheduled, though!

Hey man, that 2.7 is a sweet torquey little engine. I don’t care what anyone tells you. I low rev torque drive my vehicles, (kinda my description). I notice using the torque im both my F250 6.2 and the Bronco 2.7 that it performs absolutely great. And what I mean is there’s a happy balance between full throttle high RPM driving, low RPM grandpa driving, and medium/heavy throttle lower RPM shifts. I can’t explain it, but I always seem to find this heavier throttle, fast shifting low/med RPM range that seems to utilize the torque range if my vehicles. I feel like acceleration is almost the same. And what these add ons are doing, technology is great. The 2.7 can be very revvy, with mostly full throttle runs.

I had it in my first Bronco and it was nice overall and got better mpg than I expected (and better than some 2.3's reported here) but compared to two F150 2.7 trucks I've driven, it really disappointed on the take-off. Since that is fixed with this OEM tune, I'm sure I'll be perfectly happy!

I have never driven any ecoboost prior to the 2.7 in the Bronco. I was/am impressed. The F150 version must be a beast then. I can only imagine not too far down the road the upgrades that will
Be out there.

They really are. TFL got a 4x4 crew cab 2.7L down to 4.83s 0-60 on a track surface with just a tune. The 3.5L is a monster with 4.36s 0-60 tuned. That's Mustang territory

Results at 12:26. 2.7 ecoboost (6.15 standard. 4.83 tuned) 3.5 ecoboost (6.32 standard. 4.36 tuned) 5 liter v8 (6.94 standard 5.44 tuned)

Damn. Pretty amazing what the little engines can do with a little force.

The high octane is only needed to achieve the performance, but a Ford engineer friend of mine says that you can still run 87, you just wont get the performance from the tune. The engine senses the octane and will adjust its timing accordingly. If anyone has any different literature that says differently, certainly share.

Ford Performance tune requires premium (91+) per written spec and warranty. I believe only the conservative stock tune has adjust for 87-93.

Thanks for the info. I stand corrected . I’ll see if I can learn a more detailed “off the record” perspective on the real world ”implications” of using 87 from some local Ford engineers. Not that it would matter, since I would expect anyone to follow the language of the warranty.

That would be good to know because modern engines detect knock very well so hopefully there are some failsafe modes. I can see a scenario where you're in BFE and the only gas might be 87 or even 85 in CO. Probably very unlikely but not impossible with the limited range of the Bronco.
