FORD TUNER, I WENT WITH THIS SO AS TO NOT VOID THE WARRANTY

[Frenchy]

Does anybody know if this would apply similarly for increasing the size of the intercooler for the turbo? Would this be considered a modification to the engine that shortens the warranty life?

Yes and no. By all technicality any aftermarket part will void a warranty(unless stated like the Ford Performance tune that downgrades the warranty). With that said it still has to.be proven that said aftermarket part caused the failure. Would I suspect a aftermarket intercooler to cause a failure in the powertrain? No. Does it mean that it wont happen? Not necessarily, but again it still has to be proven. The only exception is with the Ford Performance Tune that down grades the warranty. You still have a warranty with the tune but after 3 years 36K from the vehicle original purchase date but after that you may be on your own because the Extended warranty company may say you are on your own. It also depends on what the extended warranty company will say.

I would guess yes, it would interfere with the warranty. I discussed this before with other members, they were of the belief that if you went with a bigger intercooler, it would cause the turbo to react slower giving you lag in your acceleration.

I guess I don't understand this then. I work with rail sized diesel engines. Having aftercoolers with more cooling capability raises the pressure in the combustion airbox but it doesn't have any effect on the response times. Having a larger intercooler means there is more cooling capability for the combustion air charge being pushed to the engine (density goes up). The turbo is driven by the energy in the exhaust gases (impulse only or impulse / expansion together? My large engines use only the impulse aspects of the exhaust). How would a larger intercooler core and larger transfer piping cause the turbo to respond slower?

Hows the mpg for you? Ifve had a good decrease in mpg after installing my tune

I think you are just "enjoying" it too much...
Keep up the good work.

In theory, a "larger" (please define - longer tubes, wider tubes, series or parallel paths?) intercooler will take longer (how much longer) to pressurize / depressurize, but it's a stretch to say this will affect throttle response. The throttle body is downstream of the intercooler, and the ECU actually controls the throttle opening. The variation in response (if any) will be very complex, (and likely un-noticeable, unless major changes are undertaken) especially since the charge temperature will be lower after the "larger" intercooler.

Is the new cooler now "over-sized", or is it now closer to optimal size due to original cooler being undersized? These are all questions that can be solved by experiment, but unless we are talking about a truly huge difference in intercooler restriction AND volume, I would expect very little effect on (transient) throttle response. There are really too many unknown variables to actually predict what would happen with ANY degree of precision.

So if you REALLY want to know, you have to put the proposed cooler in there and see what happens.

Also, Tom, I don't think the tune is approved for a 2109 Ranger yet.

Fo sho!!!!!

I use 93 E0 gasoline. As good or better fuel mileage compared to stock - excellent transmission strategy. Keep in mind that it will take up to 40 driving cycles for the EEC to 'fine tune' after the install. My 2019 is still a ways from being fully broken in at 12,259 miles on the odo. My drivetrain is stock otherwise.

Hey you guys, it's not like that, I called Ford and encourage you to do the same, after 36/36 if there is a failure and Ford feels it's from the tune they can deny the claim! they stated that it is a aftermarket product and therefore subject to all that applies to aftermarket products installed on the vehicle.

When I called I asked about why the tune says 36/36 when powertrain is 60K, he goes "it's complicated" he could not answer the question, he spoke with someone else and stated what I posted above.

He followed up with "the Ford tune is so conservative that we really haven't seen any failures.

I'm considering calling back and seeing what they say if I request my full warranty back if I remove the tune at 15K miles, I'm actually not that worried about them denying a claim, it's just that I think it's BS that they can sell you a "Ford Tune" and the fine print says after 36/36 it might as well be anybody's tune, they can deny the repair.

That part is the key right there, there is always a risk but this particular term seems to be the lowest risk.

Looks like Ford left itself plenty of 'wiggle room' for 'interpretation'. Everything related will be handled on a case by case basis.

The owner of Extreme Fords - Extreme Mustangs, an FRPP/Ford Racing dealer in Monroe, NC told me in person he has NEVER experienced a legitimate warranty 'decline/rejection' with their parts/services.

This is the same shop I ended up paying to install my FRPP tune as the selling dealer botched it completely. I felt lucky Ranger even started up when I went to pick it up from the dealer after they phoned me to come get it.

If I could turn back the clock, I would have done the install myself, as it's not a difficult process. Will probably make absolutely make no difference with the warranty unless one does something completely stupid.

I just want to share that I love my Ford Performance tune. Well worth the better driving experience.

While everyone had fun with the 2109 vs. 2019 thing, being a boomer myself with bad eyesight, I misread his location as Viagra LOL.
