GearHead Tunes Experience/lessons learned.

[mattr66]

Also I'm the only one that has corrected all the spark maps on the sho to make oar actually mean something. The factory took a lot of shortcuts on this platform and should have spent more time on it for model year 2013 when the computer system was refreshed.

And how about utilizing a part throttle load limit that limits load until you are in power enrichment? This isn't in the factory software until the gen 2 ecoboost and 2.3 mustang calibrations, but I got the same effect out of this tricore processor that never had this feature.... Ever have customers complain of lean misfire because the factory software normally can't limit load before power enrichment? Oh wait, the fix for other tuners is forcing early power enrichment that masks the problem, but anything above 1/4 throttle sucks down fuel and will have one **** of a time passing emissions with early power enrichment.... What about dropping fuel pressure in cold weather? Should I go on my friend?

Seems to be a trend of new members that have prior tuning experience jumping into this platform and thinking they know everything.....

Look everyone another SSI troll.

Matt/GearHead tuning is by far the most thorough and complete tuning you can get. I've tried numerous tuners and none compare to the complete package.
As far as pure performance I'd say they are very close to the top.
Also Matt is very good at explaining himself on the forums, which only builds his reputation as a knowledgeable tuner.

Massive respect for GearHead and all that they offer.

I apologize to Matt for the way I characterized him as lying and misleading. He has clearly put a lot of passion into making his octane adjustment better than the rest and that does warrant credit as being unique. I'm glad I've given him first dibs on my pcm.

Yes I'm new here. And I'm NOT a tuner at all. But you know what? I'm also not completely ignorant of what tuning entails or the practical constraints of reflashing a pcm. This is not a "WhO kNoWs MoRe AbOut TeH pLaTfoRm" ******* contest. This is some parties presenting universal facts and others getting whiney about it. Sorry for anyone here that still can't comprehend that there's nothing proprietary about AO despite the ample supporting evidence being spoonfed.

It's physically impossible for a tuner to just toss their own random lines of code into your engine's electronics. End of argument. Find me one source that demonstrates otherwise and I'll donate $200 to the site right now.

I'm guessing you're probably not bright enough to realize the irony of this post. But your sad attempt to look cool entertained me for a moment so have a Like, you poor special boy.

You should contribute to the site anyways, SiNCe yOu Is LeArnED SO mUch. Period.

You clearly know very little about computers, tuning, flashing and perhaps basic electronics. So explaining to you why you're wrong won't work because you won't be able to understand that you're wrong.

I wasn't even going to go down this road. All we have to do is go and venture into the, "Why doesn't my AWD car peel out" thread.

This Gen IV section gets spicy. Pulling up a chair.

I'm not a doctor but I play one on tv-- so let me tell you all about how to perform invasive surgery.
I almost miss the old days when there were a ton of us dumb-***** on here (include myself) back in the day.

You need to quit beating around the bush and get a 5th gen. One always needs some spice and variety in one's life.

Back in school and old job is over. No extra scratch for that now.

 

[stripSHO]

@Angrymongoose you couldn't talk over my head if you had an extension ladder on top of the ISS. You've already conceded this argument >3 months ago, so don't try to pretend like you're about to school me on the matter.

Unless you're totally replacing the factory ecu they all just modify factory settings.

 

[Eric Morris]

He commented 6 times on the last page , now he was told how it works and now no response yet. Idk maybe !

I hadn't stepped back in this thread since I have no plans to modify a FWD 4500 lb sedan, so all the bickering of the tuner tribes was getting old and pointless.

Come back a month later and it seems like GH finally jumped in and "brought the tech" - kind of. They stated they use the factory knock setup to infer octane levels, just as I postulated, but they tweaked the software to work faster and to actually affect boost levels. OK, nice job adding some capabilities to the tune. Seriously. I don't doubt that it works better with changes in octane than other tuner's software strategies and GH should be applauded for that.

But still though, there is no reading or measuring of octane levels in any way. The ECU is still waiting for knock to occur, then adjusting the timing and boost, in the same way the factory does, but with some enhancements as to what is affected.

I know this is pointless to even discuss since you guys are high on GH tunes and I'll be dismissed as a "SSI troll" ( for the record I have NO clue who SSI even is) - but given that no actual octane measurement is performed in any way and your engine has to experience knock for he "auto octane" to actually adjust anything, in my opinion, the auto octane thing is still a gimmick. The engine still has to experience knock, then pull back until it stops, which still damages bearing and rings.

It's too bad there's not a simple inline device that can measuring octane of the fuel like we can get with the gas/alcohol mix %.

For the record, I don't give a rat's ass about who buys what tune or whose parts. It's your car- have at it with anything you want. You can tune it with a fork for all I care. I was just trying to get some actual tech on this "AO" stuff since this forum is the only place I've ever seen it discussed over 30 years of owning/modifying and tuning Fords.

Have you ever watched the knock sensor in a stock calibration? It adds and subtracts timing all the time above and below the "0" knock indication. It isn't actually knocking....

I've monitored the knock sensor using the HPTuners software and it continuously adjusts while driving, more so with GearHead tunes. I've noticed they give it more range and seemingly faster reaction.
Other tunes don't seem to modify the range as much except in the higher rpms.
I'm thoroughly convinced that Matt knows tuning through and through and has spent countless weeks tweaking his tunes and it shows. His Auto-octane tune is absolutely the best "universal anywhere tune" I've ever heard of.

 

[Sharpcoolman]

I got a GH tune And BDX tuner. It is on the way. I’m so excited. Can’t wait to go full spool with the tune.

For the record. I still think @stripSHO is a dick, however I do like that guy. LOL.

I think that fits for a bunch of us on this forum.

@SM105K @luigisho I can't disagree lol. Definitely never won any popularity contests in my life!
