The dual port/direct injection on the 2.7 is a big plus. At a Bronco viewing last week I looked underhood and noticed that both of these engines use cooled EGR for emissions control. For the DI-only 2.3 that means the intake valves get hit with oil mist from the PCV AND cold exhaust from the EGR, with no means to rinse them off since there’s no fuel injection in the manifold. Anyone heard about how bad the intake valve buildup gets in rangers that have this 2.3 ecoboost with EGR?
Do you think an oil catch can would be much help with this problem?

Auto Hold Brakes: Is this the hill start feature that prevents roll back when starting on a hill? I have a technique in the rocks to back out of throttle if I can't quite make an obstacle, let it roll back a bit and try again. I assume this will prevent that and require shifting to reverse?

Also interesting that 2.3 has vacuum assist brake and 2.7 has electric.
I think its an issue of the 2.3 not being explicitly designed for turbo use, and the 2.7 is.
So the 2.3 already rolls off the line with a vacuum pump and the 2.7 doesn't.

The electric brake system is needed to be able to use trail turn assist as far as I’m aware.
Different feature, but I think TTA uses (one) of the e brakes to lock the inside rear.

Your link is literally worthless
The link was for @Zeebo390 who seemed to know about the issues. The link, a search for 2.3 Carbon, is the result of direct injection. If you read the search items in that link you will come to understand the issues about direct injection on the 2.3 engine and its carbon buildup problems. Further reading will show you that an oil "catch can" is one solution.

You can lead a horse to water...

It’ll help knock out PCV oil carryover but it won’t do anything for EGR exhaust soot or condensation. I haven’t seen inside a DI-only + EGR engine before so no idea how much of a problem it can cause. Although I’ve been searching the Ranger forums and it doesn’t sound like they are seeing much...at least not yet.

Weird I wonder why TTA can’t be used with the manual then since the parking brake uses electric actuators on both.

Maybe they are afraid you won't be smart enough to prevent a stall if you used in in good traction?

Specs are pretty helpful. and illuminating. Weight stands out to me the most. A Bronco of 50 years ago weighed under 3500 lbs. Now you constantly hear that this is about all the safety features, and added electronics, and most of this is true. Frame flex on those old Broncos is real, (or was real). However today we have a lot more aluminum and plastics. It is what it is, and it weighs what it weighs.
And speaking of weight, it is really about power to weight. A Base with nothing added has 15.62 lbs/hp with two passengers, while a 2.7 equipped BL with the same 400 lbs added will have 16.72 lbs per hp. That's right. A 4 banger Base has a better power to weight ratio than a loaded Badlands with the V6. Your best numbers here come from a Base with a 2.7. Here with an added 200 lbs you get 14.72 lbs/hp. Not bad.
Of course the auto is better at getting just the right gear all the time, but weight is important for acceleration. My buddy who doesn't believe this went out to prove how fast his Hummer got to 70 mph. He never returned.

Your link doesn't present any of that I formation at all. It's a link to this websites shitty search function in which the "most relevant" result is is literal the post you made with the link to the search results in it followed by a link to someone joking about looking for carbon build up at one of the dealer showings. After that it's mostly links going to posts talking about a color with the word "carbon" in it.

Again literally worthless
For someone trying to help, you have a funny, entitled, way of showing appreciation. I spelled it out for you in my last post, no sentence or two can give you the details that are only available by reading the dozens of posts on the problem by those that have experienced it. The short version, direct injection can cause carbon build up in the 2.3 engine, an "oil catch can" is one possible solution. The 2.7 engine with port injection does not have this problem.

If you don't know how to search the internet, here is my last tip:
Go to google.com
Replace the ??? below with the search term you want to use, to the left of the word site.
??? site:bronco6g.com

Yes, but it make adding supplemental brakes for flat towing harder, and more complicated, vacuum booster is a snap!

Interesting I never considered that.

What’s involved with normal systems that might be different with the electric booster?

I may have missed it someplace (whether in a spec or an in-person measurement posts), but have we seen the width with mirrors out? Lots of info on height, but this is the last piece I am looking for in regard to garage setup. Anyone seen that measurement or have it?

If you use a portable system that sits on the driver's floor (BlueOx) with the brake pedal arm, or the tow bar unit with the cable thru the firewall (ReadyBrake) to the pedal you are good....., if tow mode activates the brake boost pump. I use the Roadmaster InvisiBrake system on a vacuum booster vehicle, which will not work on a electronic actuated boost system. I have an email in to roadmaster asking if they plan to make a plug in interface unit that will activate the electronic boost unit using the vacuum produced by my system. If not I will have to start from scratch which will suck.
I am not sure if the purely mechanical systems will work on the 2.7's system with the push to start off, or if tow mode activates the boost pump when selected. Ford has as usual not supplied any info on this so far.... you know how to grow mushrooms right?

Appreciate the break down. It appears many vehicles are switching to electric boosters now.

I believe you’d be fine with pedal pushing systems as from what I’ve researched showed that you want absolutely zero vehicle assist on the brake systems because it could cause over braking. They’re supposedly strong enough to apply unassisted braking. Don’t know much more than what I was able to dig up in some videos and forums.

I use the RVI system, love it. On vacuum systems you cycle 3 times to burn off vacuum. On electric systems you're good because booster does not run unless ignition is on.
