2015 EcoBoost Engine Replacement

[shogun32]

if the boost gauge is any indication the Ford tune slams the motor into high boost even at low'ish throttle and RPM which is IMO a really bad idea. Torrie programed mine (without prompting) so that the meter was reading 5-12psi at small throttle and only got into 20psi once the engine was spinning hard (>3500?) and at big throttle openings. Car ran SO MUCH BETTER than Ford factory tune.

Yes. It’s called map targeting. It’s torque targeting.

After market tuners all of them as far as I’m aware, are torque targets. There’s a big debacle on what’s better or not both has pros cons.

But the aftermarket guys, torque targets. It hits the targets in all gears, no restrictions pretty much.

Ford limits in lower gears, and only gives enough boost to hit target
Not a penny more.

Saw it with my downpipe it would fly to the psi, but as soon as it hit, it was a hard brick wall and drop psi’s down

Aftermarket would keep climbing to its target and hold

Gear 1/2 doesn’t have the same power on ford tunes as gear 3+ Which imo, is where people play the most.

Rode in a stage 3 full bolt on car recently Cobb, it was much heftier than mine. Every aspect.

uh no, my observation was that Ford would spike the PSI on any throttle movement - pinning it to 20PSI and hold it there - it did NOT waver, it did not drop unless you came off the gas completely. That's not my definition of "gives enough boost to hit target".

Driving both mine and a HPP with Ford factory tune was an exercise in frustration. All that boost and the engine made lousy power till >4500RPM and car was slow to accelerate. With Unleashed the boost was modest and yet the RPMS climbed rapidly and the kick in the ass was pronounced.

Ford knows what it’s doing. Aftermarket tunes you will get that power + more.

My car doesn’t go over 20 psi in 1/2 Itl hit 22 psi in 3rd on

Maybe ford thinks 20 psi is safe for 1/2 there has to be a reason why 3rd on fp gets 22 but not 1/2

Aftermarket tunes can hit 22-25 psi in all gears.

sure, but it doesn't need to! My car accelerates cleaner and harder at 5-12PSI than the Ford did at 20PSI.

Doesn’t make sense.,

20 psi is stronger than 5 or 12 psi

NOT when your timing, fuel maps are wrong. That's my point. The Ford tune SUCKS ASS it's incredible how shitty it is and it has nothing to do with what MAX PSI it commands in what gear. Force feeding an engine 20PSI when it can't use it, is pointless. When I roll into the throttle with Ford the PSI gets pinned to 20'ish. When I do the same thing with Unleashed it starts around 5, increases to 12, and once the tach sweeps past 3700-something THEN and ONLY then does full boost come on. In ALL stages of that accelleration the Unleashed Tune pulls HELLA better than Ford's does.

I can't speak to COBB or Lund tuning as I have no experience.

Meh I like you shogun but I have to believe in fords “tuning stock and aftermarket” as safe. They wouldn’t mass produce a million car and ecoboost trucks, and let their cars blow up on a large scale.

They are doing soemthing right. It’s for epa compliance but also to not blow is prob why feels weaker idk

how did I suggest in any way that the Ford tune was going to blow the motor? Whatever machinations Ford is doing is obviously safe enough, it just makes crap power delivery vs what is possible when not cramming so much boost early on.

I couldn't believe my eyes when I first saw it either. But the throttle connection, drivability, and acceleration were very much improved. I drove my car tuned and not back to back. I drove my car tuned, back to back with a 2020 HPP. My car (tuned) was WAY better.

Could also be that Unleashed has created a tune to feel faster and more powerful, even when it isn't. Perceptions are everything, and playing with contrasting boost levels can make a car feel fast, even when it isn't.

Anyone familiar with 1980s & 1990s turbo vehicles knows what I'm talking about.....tons of low-boost/lag at low RPM, and then BAM a hit of turbo power that shoves you into the seat. It's actually thrilling, and feels fast as hell.

It wasn't actually fast, but it felt fast when that boost came on, and if you kept it in the narrow boost range/higher RPMs.

And that's what it sounds like Unleashed has done.

Do you still have this car? Or did you sell it for the GT?

you couldn't be more wrong! There was no turbo hit - it had real torque everywhere, even in the basement and would swing the RPM needle way faster than the Ford tune could manage. Yes there was a surge in power once the engine could utilize the full 20PSI but it would not be characterized as a 'hit'. Torrie is no dumb-ass peddling tunes to simpletons.

When I mean back to back testing I mean it literally. Drive 20 minutes over my test loop. Park it in the Kiss-Ride lot, flash it, drive the loop immediately after. It was amazing what that EB could actually do when the tuning wasn't junk. Even the HPP would fall on it's face whereas my non-HPP would pull with a fierceness all the way to redline.

Unfortunately I don't have the car anymore - sold it late September or I'd demonstrate it in person and let you drive it. I bought the GT first and then 5 months later added the EB to the stable. Owned the EB for not quite 1.5 years.

Was driving the other night, heard my turbo blow off, then a loud crack, then what sounded like something dragging on the ground, and then my engine shut off completely and wouldnt turn on.

My guy hasnt taken ithe engine out yet, but says after his first run of initial tests that its most likely Im gonna need to replace the engine.

Anybody have any experience in that regard? Advice, pricing, timing, engine recommendations? Would love to hear experiences

Sorry to hear this happened to you but I had a 15' EB. Back then many members who had them tuned experienced "EcoBoom" especially those with the Spanish engines. Your car sounds like the perfect storm as you really do not know what you bought. If you do get a new engine buy the latest model year you can afford. The newer the better. Then you can add whatever mods you want.

Also search Ecoboom in the I4 sub forum. Here's one.

Appreciate that -- yeah Im learnin a lot about the EcoBoom haha. Not fun

 

[UnluckiestDriver]

Mine is an '18 with right at 66k now. Completely stock but I can't say that it hasn't seen redline a time or 3... Still runs like a top though and I do have cash put back in case.
Good luck with yours, ut sucks that you are going through this but my guess is it's well worth repairing.

There you go! Yeah shes a beast so definitely cant quit her yet. And with all this govt stimulus its like they know some of us need to make engine swaps -- finally doing something good for the people hahaha
