Is MP215 the way to go?

22727 Views 80 Replies 20 Participants Last post by  XR650R
Just got my new ST (only driven 1000km) and is thinking of getting a tune for it. I wanna keep the warranty on it, so it must be Mp215 that is the way to go? I also want as much torque at high rpm as possible as a NA engine without loosing too much midrange torque - which tune is best for that?

Thanks in advance.

From my understanding of the FR warranty is that it scraps the OEM FoMoCo warranty and applies a 36K/3 year Ford Racing warranty as long as you run the proper fuel/installed by Ford Racing.

Why Ford went to the trouble to bring Mountune to the US when they're making OEM FR parts I have no idea.
Probably because theirs will be better. No offense to Mountune, I love my MP215. But the only reason I'd see Ford Racing not having an issue with it is if they limited Mountune to a improvement that they knew they would be beating with their own warranty covered tuning option. Plus it will be cheaper from initial reports.
Difference with Mountune is after your factory warranty is up, you can use your MP215 to upgrade to the Mountune Racing options which the sky is the limit on.

Is it possible that Ford is just taking the Mountune package and renaming it as a Ford item?
Highly unlikely. I don't see why Mountune would let them do that as it would basically cannibalize all of their R&D / efforts, even more so than the competition that will be caused by Ford Racing offering a warranty covered product. Unless Mountune somehow convinced the much larger Ford corporation to pay them royalities, which again, I find to be highly unlikely...

I think what we have is Ford sees there is a demand, has known from previous generations of cars that there is a demand, and is simply catering to that demand - completely irrelevant of the fact that Mountune has and is offering something similar. Ford is doing it's own thing and providing an additional choice. Ford probably can offer a better choice overall because Ford controls what is allowed under warranty and what is not - something that Mountune can not do, as they have to get Ford's approval, and Ford better knows what the limitations of their engine is - even though Mountune is probably very aware of what the Ecoboost engine can do as well.

Just saying...Ford allows Mountune the luxury of being covered by their factory warranty. So Ford has full control over what options are available as long as you're referring to keeping your factory warranty in tact and modifying the car. (Of course, we're not getting in to the legal requirements set forth by various State and Federal laws)

It's kind of pointles, really... at least for the current owners (those that drive regularly). As I'm assuming the 36m/36k Ford Racing warranty that takes over the car's factory warranty with the new tune likely starts from the day the car was purchased.... so by the time this is released, most of the benefit of getting it through Ford will be a mute point. Once you hit the halfway mark on your car's warranty, you should probably just wait it out and get Cobb or one of the other tuners since being in warranty is the point going with the MP215 or this new FR tune... At least with Mountune you can go up to the Mountune Racing stuff which is what I will likely do when my car is out of warranty...

so really it only makes sense to do FR or MP215 when your car is still fresh and very low in miles.
What you're saying doesn't make much sense. Firstly, customers choose this option because they don't wanna risk anything. Secondly, the 2 year warranty isn't the only thing Ford offers if you service your car during that period (and no COBB tune for iunstance), but when the warranty is up and the car breaks down, Ford is more open to compensate.
Sorry, I think you may have misunderstood my post. I am referring to the decision making process a Fiesta ST owner goes through when considering their available tuning options. Typically, an ST owner would only consider the Mountune MP tuning kits if they would prefer to not be concerned about having issues when utilizing their car's factory warranty at the dealership or with Ford. The MP215 is more expensive, offers less gain, has less support (only comes with one map), has less gauges, etc. and again, it cost more than the competition. Plus you have to pay to have it installed.... so it's real value/benefit is only the fact that it doesn't impact your factory warranty.

If factory warranty is not a concern, typically an ST owner is going to go with one of the other tune options such as Cobb, Mountune's MR, etc. as it's cheaper and usually offers better gains.

With that in mind, your factory warranty starts from the day of purchase(so to speak), so ideally the best time to get an MP kit or a tune that is covered under factory warranty is as earlier as possible or rather with as low mileage as possible (so that you maximize it's only real benefit or value vs the competition)

In my mind, I'd wager:

MP215 purchased at a dealer and installed by the dealer (therefore not impacting your warranty) at 0 miles is better than:
MP215 purchased at a dealer and installed by a dealer at 25,000 miles or a year/2years in to ownership.

The MP215 kit (installed by a dealer and at a dealer, keeping the factory warranty) begins to lose it's value the more miles you put on your car vs. the competition (other tunes) as they are not covered under warranty in the first place, so mileage or length of ownership, doesn't matter for them.

Its only cheaper until the damn thing breaks down :-D (and the breakdown isn't necessary have to do anything with the tune, warranty still isn't covering)

A risk I´m not ready to take, and probably one of the reasons I bought a completely new car. I know what you're saying, your having more bang for the buck with the third party options.
Yeah, definitely. For the record, I have the MP215. I love it. I've driven in one with a Cobb Stage 1 AP. Honestly, the only thing I miss in my MP215 is the torque limiter being removed and an oil temp gauge. That aside, I absolutely love my MP215 and the lack of concern should something go wrong with my car and I need to use the warranty.

Unfortunately, no numbers on either car. Just butt dyno. It improves the power band noticeably, as others have indicated. The car just has power ready to go any time you need it - the mp215 just seems to give you more of it. I really really wish they'd remove the torque limits because I can make due without a oil gauge...but in the Cobb Stage 1 Fiesta, that torque limiter being gone is VERY VERY noticeable.
FWIW, I had the MP215 installed today. I was a walk-in customer to my Ford dealer and they got it installed in 45 minutes, no problem.

There is a noticeable increase in power, mostly in the mid range torque. The car pulls hard all the way to redline now. I thought I'd be annoyed at having the kit keep the torque limiter, but honestly it's not a concern to me (1st gear simply spins tires now...not sure how increasing boost would help?).

I'm a happy customer and would recommend it to anyone in a flash. The only concern I have is that I'm only getting 21psi of boost WOT in third.. I've seen reports of people hitting 23psi. I'm wondering if I have a loose hose clamp somewhere?
Yeah, 21 psi is low in terms of what you should be getting with the MP215. I think the highest I've gotten is 24psi if I recall, but I can reliably and regularly hit 23-23.5
Hmm... maybe someone from Mountune will chime in. In the meantime, I'll put the car up on ramps tomorrow and double check the hose clamps...I checked them a week ago when I did my oil change and they were all fairly tight.....
Yeah, I'm no expert at this by any means but I am under the impression all kinds of things can impact your turbo's ability to make power. Environment, altitude, etc. so hopefully someone can chime in and give you some insight or things to look for.

Yeah, has to be. Car does that stock (maybe not the torque).
