LMS vs Gearhead "Canned Tunes" Comparison

[76FoMoCo]

then going to put it up against a AJP tune and then will put up the same with meth.
dam going to need a punch card and the dyno shop....

Any new news on that IC?

Yeah 45 of them in circulation now.... New best ETs being run.... Another batch should be in our hands by the end of April...

the new tune is label 93V11 but is NOT the same as the early V11 the shift points are not the same and the power is a noticeable less. going to put it on the dyno in the next few weeks.

Thanks would love to see the Dyno

Interesting... agreed. Better tires would get me there for sure.... add downpipes and both tunes are in the 11’’s

Curious though.... yours had more torque, but what does the torque curve look like? I’m at 400+ torque almost instantly.

I get 400+ at 2700-2800 ish rpm.

To answer your questions directly about the V11 issue and tuners "tuning around the problem".. the answer is that the V11 tune is a summer oriented tune. LMS is just running too rich at the load they are running for the stock HPFP. Colder air compounds the problem since their tune doesn't adapt for it. Gearhead's tune will pull back the boost when the air is colder cause you are already hitting desired load. LMS will start to close the throttle. Different approaches but one works better than the other as preventing low fuel pressure issues.. aka stuttering/hesitation.

But from LMS standpoint.. if they roll back to another tune with less power then people get pissy about it and complain. The tune will run fine in the warmer months no doubt... might be worth loading the 91 octane V11 tune when its colder out.

Mine did it all year here in the Midwest, cold, warm, hot....

I'm talking to Anthony now about the V11 tune i'm having major issue with hesitation on WOT. Anthony's answer was "This is caused by the high pressure fuel pump pressure dropping because these cars are physically making so much power that they need more fuel system." LMS gave me a winter tune has anybody tried the new tune i did not installed yet= looking for some feedback please, i read the new tune is safer but not as much power?.....I've also read GH has fixed the shifting and hesitation problem with there tune if so please let me know..... Thanks

"....these cars are physically making so much power...." (they need a HPFP). This still doesn't make sense. My Gearhead tune made even more power than my LMS 93 V11 and no missed shifts and no WOT hesitation. Anthony/LMS still hasn't answered me on this.

Agreed all year round SMH.....

The fuel pressure problem is running them too rich and puting extra demand on the fuel system. The argument is durability at wot from running leaner. From my experience, too rich and not enough timing will cook the catalytic converters much faster than leaning it out a bit because the rich mixture is causing an exothermic event in the cat itself (burning fuel in the cat). This is what happens at startup when raw fuel and negative timing is used to "light off" the cat. You DO NOT want this at wot..... On the cold weather issue, it is very easy to set a load (VE) limit that cannot be exceeded under any condition....

But with the engine itself, is leaning it out a bit impacting longevity in a negative way vs a bit rich?

As long as you aren't detonating and cylinder temps are under control (these engines also have piston-cooling oil jets) you are fine. Running leaner also reduces carbon buildup in the cylinder and between the rings that eventually leads to ring gap closure and breaking the tops of the pistons off on high-mileage engines.

How are we monitoring cylinder temps and do we know the thresholds?

No way to actively monitor unless you add a probe. EGTs are a good indicator though and I've monitored on various projects and generally know where they should be.

Let's remember this is a modern, direct injection engine with turbo'ed operating conditions in the design since day one.... This isn't adding boost to your NA small block Chevy where you have to run them overly rich to keep them together...

I finally caved to all the rave reviews I've been seeing Gearhead get the last year and half or so. Installed my gearhead tune this afternoon, didn't really have a chance to drive it much until a little bit ago.

Everyone talks about how smooth the shifts are. I always thought, oh they are just feeling the same way my transmission shifts, because mine never seemed clunky or overly forceful. There was probably something wrong with their other tunes, mine is fine.

Well I stand corrected. Compared to the Gearhead tune, every other tune I have used (unleashed, LMS and AJP) is extremely clunky and not smooth at all. I was absolutely amazed by it. It just always feels like you are in the right gear.

If you haven't tried it, I very highly recommend it. I would almost bet my own money that once you try it you will not bother ever switching back to your previous tunes. It's only a hundred bucks.....Matt you need to up your price, because a hundred bucks is not doing your work justice.

Glad it’s working out! How’s the new HPFP running?!

Hope this thread helped you and glad you love it! I couldn't agree more - I had a hard time finding the correct words to use explaining the shifting!! I still don't get it - how can the shifts be instant, lightning-fast, but not harsh at all?! It's like when watching YouTube videos of an Audi R8 shifting for example! Matt is the man!

Speaking of longevity and oil, running full synthetic SN+ compliant products will aid that effort in the long run. Most major brands are now up-to-date, and boutique oils like Royal Purple and Amsoil as well. Redline's Pro series is what you'd want to run.

putting it on the track on sunday and on the dyno wed. Then I have some time with Brad...... then more track and dyno....

I always take my car to the Ford dealer since they gave me 3 years of free oil changes and they do all the maintenance, etc. Wonder if they'd let me bring in my own oil to use? What's you top pick, Redline?
