What makes you guys assume a tune has to "learn"?

One more thing. The first dyno was done at 76 degrees and today it was 88 ambient temperature. Also, i know different dynos, but LMR dyno’d the Bullitt and it made 426, 391.

??? Doesnt the computer learn the driving habits and fuel etc to adjust and perform to optimum level?

No. The transmission learns driving habits but the engine parameters shouldn't. If anything, the tune would perform best right after loading due to the KAM being reset during the upload

The tune doesn't reset the KAM on its own and a KAM reset will leave you down on power until it learns it's optimum fuel trims...

Hey guys, got another dyno done after the initial install and dyno (https://www.mustang6g.com/forums/th...-tune-for-2018-gt.122943/page-39#post-2902710) to put this to rest on two fronts. One, the car has to learn and get accustomed to the new tune and Two, California fuel sucks. After running 93/94 octane fuel for several weeks, here are the results.

So looking at your 1st graph vs. this recent graph. If i am looking at it all right, you picked up 20 peak hp and about 8 tq with the ford perf pack?
Overall, How do you like it?

Number wise, that doesn't seem much at all, but how does it feel?

That is actually better than advertised for hp considering they were saying 19hp at the crank. So at the very least it over performed in that aspect.

I would say right after my upload of the tune I didnt notice much of a difference. But after some driving/mileage I felt more of a difference. Also, it was me learning the response and RPM band changes. As far as transmission, I have the manual. So dont know what it could have changed for me, since I am doing the shifting.

I did it. I added 3 gallons e85 mixing with a full tank of 93 e10. I beleive that is e24 from my calculations and like 95 octane. Went on long drive and will do another tank again next time.. I'll see if I notice any difference overall. First time trying this though.

Yeah seems not too bad to me. Tq gains in the 2.5k to 3k area are pretty nice too looks like 30ish?

Hey All,

Does anyone know how the warranty for the Tune would work with the factory extended warranty? I'd like to get this setup for my 2019 and maintain the extended warranty I have, but not sure if it is possible or not.

 

[wade001]

3yr/36k mile warranty from the date the car was sold. for example if you had the car for 1 year before you put on the kit, you'd have 2 years left on the warranty of the kit.

THEN after that warranty is exhausted, you'll fall back to MFGR warranty (if there is any left). then after that, you'll fall back to your extended warranty.

knowing how dealers companies work, im sure, if able, they will try to blame whatever they can on the tune, that is no longer in warranty, as a way to get out of fixing something that may still be under warranty.

maybe you have a good relationship with your dealer, maybe they'll be fair, who knows

Exactly. If this tune from Ford is so safe, then why does it void 2 years of the original power train warranty.

I think the tune is totally safe, as with most tunes by companies that know what they are doing. It sucks that it does cut the warranty down 2 years and really makes this a trade off.

I personally been closely following this thread, bouncing back and forth of what to do...get this tune and other parts, get a real 93 tune and other parts, get the roush P2 SC, or just leave it alone for now.... But my itch to mod is strong.

As someone else mentioned before, there seems to be a mixed consensus weather this tune/pack is worth it or not. Some say its disappointing, some say they like it alot. I wonder where the difference in opinion is coming from? Expectations? Fuel being used? Auto vs. Manual? The KAM thing that needs time to relearn or be manually reset?

Looking at the dynos, this is pack good for about 20WHP and 8 Peak TQ but up to about +30TQ gains under the curve. You would assume that is a difference you would feel and even see if you were to race side by side vs. a identical stock gt. But that is not what another user posted happened when he raced his buddys stock gt. But then someone goes to the 1/4 mile track and drops .2 tenths and picks up a couple mph with this pack vs. stock. Maybe you just wouldn't see a couple tenths on the street? Im not sure. I was really planning on originally getting this pack, but this thread has kinda left me confused about it all.
