LMS vs Gearhead "Canned Tunes" Comparison

[StealBlueSho]

Too many maybe's. I work in the plant that produces our motors and can guarantee you each and every little change is documented. The process is called 'manage the change', and you'd better bring your data, as the revision will be scrutinized by many departments both in and outside the plant, including vehicle operations (VO) Changing the length of a bolt by 3mm could take up to two months to get approval.
I totally agree with your other point, the highway ramp. Each morning on my way to work, I climb a ramp leading to a 70mph speed limit, and take that opportunity to clean out the crankcase gases collecting in the system. That is up until my new v11 tune........
Ford is looking out for us with stringent Quality standards. That I can say first handed.

Man... I wish all tuners were able to do this... or better yet... ANY tuner... cause then I could get a 100k mile warranty on a tune... alas... this is not the case...

And we're all looking forward to that product release.

Hopefully soon! **fingers crossed**

DPs help more than catback.

Matt, I will be calling Monday to get a Livewire TS and auto-octane adjust program for my 15 sho.
Any tips?

Just be patient with phones. We are a man short right now.

I have datalogged the V11 tune and have commented on the hesitation. I am willing to bet the hesitation is certainly fuel pressure related. LMS runs rich and with this particular tune it causes the fuel pressure to drop significantly and not recover.

So the firestorm high pressure fuel pump does nothing to help the hesitation?

I'll keep you posted when I try out the gearhead tune.

The Firestorm HPFP is their fix for the hesitation.

And I already have the Gearhead auto octane tune and E30 blend tune as well as the LMS V11 and a custom LMS E30 blend tune as well.

I don’t have any issues with either tunes.

Two questions re post 87:

@OmaHahn: Did your dyno operator capture a/f ratios on those runs? Can you post those?

@LMS: Please explain how that big torque dip that starts at 3500 rpm has anything to do with fuel limitations. If there is enough fuel to make 320+ hp, then why is there a big dip when the engine is only making 250 hp? I can understand that if the pump is limited that would explain your peak number being lower, but not why the number is significantly lower in the middle of the rpm range.

Unfortunately I think a lot of the information out there about DI engines being able to handle leaner tunes comes from tuners who run them leaner. Additionally, people often look over the fact that a production vehicle has Cat over temp, Turbo over temp, ****** over temp, hego over temp, and all kinds of other safety items in place that put a a great deal of fuel into the engine to "save" those components and lower the EGT's, what we do is balance that out so you're less likely to have various temp limits hit in the first place. Unfortunately, many calibrators turn all of those off AND decide that the factory fuel mixture is proper for all conditions, or worse, even leaner than stock.

on a forced induction car, fuel mixture plays a pretty big role in making power, leaning out the mixture can be 20-30hp, but at potentially dire costs.

This is why we are adamant about these cars being out of fuel and why people see it with our tunes more often. Leaning them out cures the symptom, NOT the problem. Now, we can pull power back so the fuel demand is less, which does fix this issue, but then people complain about the power reduction.

The only 100%, proper way to keep power AND the proper fueling is our upgraded pump.

I only run WOT 1% of the time I'm driving.
So, all of the hundreds of successful v11 drivers are only successful because they run your upgraded pump?

I'd settle for 50,000

omahahn. Do you have, or are you considering buying, a high pressure fuel pump?

No, all pumps are mechanical part with tolerances and an acceptable range of performance. Some OEM pumps are a little better than others, and some worse. Because of that some people run into this issue easier than others, but once cold air moves in it substantially increases the chance of it happening.

So, we can back power off (we used to offer specific cold weather tunes for this before our pumps came out) that pulled power out to use less fuel. It is an effective and safe solution, but the only proper way to address this is to do our pump and eliminate the pressure drop issue in the first place. Then this opens you up to being able to do e30 tunes as well

What is the degree of difficulty in changing fuel pumps.

Hey Shoblock! I was but after all this fiasco and looking at pricing to make power for this car - I think I'm done with mods. My plan now is sit back for about a year then buy a 16+ Audi S6 and just a stage 1 APR tune will get me more power than all these mods added up.

I feel your pain. What spark plugs do you currently have in the car? I'm going to do a couple of more things to my car before I throw in the towel. Been fat, dumb, and happy up until v11.

pretty simple, I would say basic mechanical knowledge is all you need and some basic hand tools. we designed it to require as few modifications as possible

I have a post around here specifically detailing replacing the stock HPFP with the Firestorm pump...

It’s literally....

1: 1 quick disconnect fuel line
2: 1 nut for the high pressure line
3: 2 torx bolts
4: 2 Allen bolts
5: extending the electrical connector by untaping for the wiring harness.

It literally takes 15 minutes.
