how is the h&s tunners working out for the lml? what kind of fuel mileage are u getting? any problems out of them? hows the trans holding up with the race tune on them? has anyone put a full exhaust on them yet? what are the fines if any if u get caught with out your dpf and urea injection?

Also, if you don't mind me adding, what do your guys (with H&S tuning) EGT's look like on some long WOT runs???

Sold my mini-maxx. Fuel milage sucked. Truck was always in regen. Power not bad. Still had factory exhaust on.

The H&S Tuners have been doing great on the LML's. We havent had any issues with them at all. I wouldnt run it hard all the time in the top setting though, it can wear on your trans pretty quickly.

Been working great for us aswell

Sold my mini-maxx. Fuel milage sucked. Truck was always in regen. Power not bad. Still had factory exhaust on.

With the stock exhaust the DPF will get restricted sooner if you run it at the higher power levels. the DPF egts restricted when it catches soot, and there will be increased soot for it to catch with the higher powered tunes putting more fuel through the engine. This means more regens, plain and simple. The added regens were simply due to your driving and putting more soot through the DPF. If you're gonna play, your gonna pay with the stock exhaust.

Anybody dyno their trucks yet at the highest setting?

Im waiting for the mass amounts who jumped on the power bandwagon to start having major issues with the transmission, to be honest it is the only thing right now that keeps me on the thread.

i know quite a few that have been beating on them on the higher settings and no issues so far but that doesnt mean some wont arise down the road

I have had zero problems with mine. Full 5" turbo back exhaust. I use my truck every day for work so I don't do anything stupid, like full power runs up and down the street, beating the crap out of my transmission. I normally run it at the lower setting, mild, especially since I tow so much. I like it for NOT having to mess with the DEF problems.

Almost 10,000 miles since I installed the tuner and NO issues with check engine lights, limp, ect.

Thanks for the info. The only issues we have had with the LML are mainly keeping up with GM and their waves of calibration files they like to release (around 40 of them just last month). Other than that we have many customers with thousands upon thousands of miles without so much as a hiccup. Transmissions are holding up really well, much better than the LMM it seems. We have yet to see a failure on our own, or any customer's truck.

Two things I'd really like to see, and from talking to your engineers, I think both are in the works:

1. Shift-on-the-fly for the LML.
2. Speedo correction for larger tires.

My understanding is that with the complexity of the LML chip, the speedo calibration is a real nightmare. From the sound of it all, seems like GM has totally abandoned the KISS principle. (Keep It Simple Stupid)

Just a couple items on my wish list!

How can there be issues with the transmission when the POS is constantly defueling!
50 rubber 30 feet nothing do to defuel and gear change 50 feet rubber in the next gear 30 feet nothing do to defuel then rubber again etc etc

Will the LML transmission be tuneable?

I disagree 100% Shift on the fly is stupid you can not transmission tune on the fly! We need a better tune
I beleive they need to crack the TCM's. Honestly H&S's only hope imo is if Mike from Kem Performance can get involved since he works with them and may be he can get some better TC control lug the truck down and load the charger harder. Increase the solenoid pressure under high throttle positions etc etc. Surely these trucks can make more than 30PSI Boost if not that is sad.
There is an insane amount of work that needs to go into these trucks yet. I dont think we now the half of there potential but as far as I am concerned shift on the fly is a waste of time
my 08 6.4 has ran the KEM345 tune for 2 years. I tow up to 15,000 pounds with it, it makes 10L/100 or 25MPG and it will destroy everything on the street and it is dependable. One good tune is all we need. If the tune is good enough you want have to shift on the fly you can control your power usage with the right foot.

Not a Ford trans...

Can't do much with an Allison without hard parts.

Thats good to know. Been on the fence about getting this setup, just not sure if I want to kick the warranty yet or not. Glad to hear everything has been working out good for you.

Not a Ford trans...

Can't do much with an Allison without hard parts.

OK so I am doing some research to understand why the Allison is such a POS.
So I was told by my "Ford" transmission guy the following

The Allison is based on a big truck transmission is what not intended to be used for race purposes which is probably why every fast duramas runs a duraflight.
He said the Ford is controlled by Voltage from the throttle position to increase line pressure.

He said the Allison uses a valve body like the Old 6.0L fords which is why this truck downshifts at the sight of any hill. he says the valves stroke back and forth which controls the line pressure. He said that it is adaptive and it will store in its memory what it thinks will be best for me. He said they have to defuel because of the poor design where only certain planetaries are in drums where the Ford 5R110 uses all drums so it can shiflt like a rail car.

Dont understand everything yet but I am trying to get my head around these allissons. If there are any experts here of the differences I would sure like any help I can get. What about TC control? is there difference's between the TQ control in the 2?

I would say not to listen to the guy who fed you this load of info. yes the ALLISON is a heavy trans, no it was never meant to shift fast as the mass of the internal parts are HEAVY compared to what the others use. Defuel or SEM is used to provide a smoother shift while minimzing wear on the clutches. Other manufaturers use this is well with clutch to clutch trans as it is just the nature of the beast. It's not like the old days where you had one way bearings, stators, clutches with bands that had safety nets built into them. With the advent of modern controls we can now use transmissions that no longer require bands and one way safetys in them. These designs are strong and rugged, but do not provide the old turbo 400 with a shift kit feel. The new 2011 ALLISON is an all new animal as well from the older models, and does use limited control over line pressure via the TCM. Older ALLISONs used a static set pressure and used the trim valves to vary the pressure to the clutches. they still use trim valves, but they now added in a line pressure solonoid so they can lower line pressures after a shift to reduce HP draw and lower trans temps. Find some off Mike L's posts regarding the new technology, and hopefully he will have his new kits out soon that utilize some of the newer LML parts.

19 post and you already sound like a Ford troll. Yes nothing in stock form compares to the 6.4 stock for stock, but a built tranny duramax with EFI will lay waist to your heavy 6.4. Your Ford is not as fast as you think it is
H&S has some pretty rough tunes right now as it sounds but hopefully we will have some more options to come in the future.

Thanks Man,
That is what I needed to hear because it was one of the reasons I bought this truck. So in simple terms when some one figures it out will we be able to use that line pressure solenoid to help it shift faster electronicaly or will we be having to put hard parts in to get it to shift faster?

If you actually read some of my other posts I am just a frusterate new GM owner
I own 3 diesels right now
2008 CC 4X4 6.4 Kem345 tune through Spartan Dash Daq
2010 F250 2WD Custom Short Box 984RWHP - 1949 RWTQ
2011 LML Denalli HD - HS tune

And by the way you need a lot more than a transmission and efi live tune to run with a 6.4.
Want me to list them (what do you know a ford troll knows more about a LBZ then a GM enthusiast)
Here is the list
Tie Rod sleeves, fuel plug, ported fitting, tank pick up, and a lift pump and you might get into the high 12's low 13 where a Spartan tuned truck will do with just an intake exhaust and tuner. Thats not what I am on here for I am looking for help on my LML.
I dont expect to get into the 12's with my new LML but at this point anyone who thinks it is fast its not!
I have built lots of LBZ trucks and once the mods done above they are awesome. That is what I was hoping to get from this LML.
I already have a 1000HP truck thats not what I want
I want something I can drive every day to work pull the skidoo trailer on the week end and beet 95% of the sports cars on the street. While making 20+ MPG. (just like my 6.4 but I also want the air conditioned seats and all the nice comforts that this Denali HD has)
That is what I was expecting when I bought this truck and at this point it is not even close to meeting my expectations.

Oh and one more thing I like the looks of my new LML
It sweet that a 4x4 with 285/55/20 sits as low in the front as my 2010 2WD race truck that has DJM 5" Drop beams. That is another reason why I went to a GM. I hate lifted trucks and wont be beating this thing down lease roads so lower the better.
Here is a quick vid of it from 10 minutes ago.
I learned to put the truck in manual on the hiway so it stops downshifting like a 6.0L and it actually pulled some nice speed. Its dangerous in auto because it cuts the power to downshift so you never know what the truck is going to do when you pull out and mash it. Putting it in manual fixes that
I would like to do some burns out vids but am still learning how to drive around the defuel. I will keep practicing :)

You are the guy complaining about a 1.9 60 foot right? That is a decent 60 foot for a 7600 truck in 4WD.
my 2WD ran 11.65@129.5 with a 2.3 60 foot. lol cant get 17" slicks

How did you keep your truck from defueling?

If mine would run 13.8 I would jump for joy. There is no way mine would in the state it is in now.
What did you do that is so much different?

I have turned stabilatrac off and launched in 4WD but all it does is defuel.
13.8 I would be happy and quit bitchin if I could get that from this rig.

Well that is a pretty simple list dude. And you don't know as much as you think you do cause you have three of them wrong. You don't need a fuel pickup, ported fitting, and I don't even know WTH a "fuel Plug" is. You need EFI, trans, exhaust, fuel shim, lift pump (AD165 doesn't use a pickup), and tie rod sleeves.

Show me a comparable list to that one with stock turbo/fuel systems 6.4's

I think you have something wrong with your truck or the tune.... Could be you just have a lemon

By the way your truck does look Kick ass:cool:

Its everyting we did to my freinds LBZ and we are dead even with my 08 6.4L. He has no sleeves yet so I take him standing 1/4 and he has a 1/2 a vehicle length by 120MPH when rolling into the throttle.

Dude if you like my lml check out my other youtube videos I know your not going to be a ford guy but I think I have built one of the sickest street trucks in the world. The links are in my garage under my 2010 F250. I was thinking about going to work under the hood of this LML but want to figure out what needs to be done first.

Derail!!! but anyway here is what we put in his LBZ that you were questioning,

I never complained about my 60 foot i was happy with it. I don't have a video of it and it didn't defuel at all just the traction/torque control system made it pause between 1st and 2nd gear. And all i have is the mini max tuner and straight pipe. It was 81 degrees outside and elevation is about 3200ft

In my LML none yet its brand new
13.8 at 98MPH with a 1.9 makes sense that all jives I am not calling you out but I was hoping you can take a photo of your time slip and post it up I am sure you kept it.
was it consistant high 13's or did it get faster as the transmission learned?

as it sits I dont think mine would run a 14 second pass.

My LML only has 500KM on it I will try to run it July 9th in Calgary at the NHRDA event in ET. Could it have some new flash that would affect its tuned performance or if the tune goes in would it be fine? It was straight off the assembly line the frame paint was still sticky when I got it. Does the mini max have to be plugged in? Mine is in the glove box. Any help is appreciated.

called H&S and it turns out I am running an old version 6.6.6 and I need 6.6.7 hopefully that is all my issues. H&S service is second to none.
And just to clarify Hot is faster than Wild right?

May be because my truck is so fresh it needs the 6.6.7

Mine pulls hard like that up top occassionally when it is not busy defueling.

Its raining now but I will do a vid this week end to show my frusteration.

I had my change fuel filter come up on the dash

Has anyone else seen this when running the H&S?

May be I have an issue there.

Some trucks cannot keep up with the fueling the H&S tuning demands on the HOT setting. If you watch your rail pressure during a WOT run, you may see it drop to around 20,000 psi. If it does, your high pressure pump cannot keep up. We put our tuning on the verge of draining the rail, as to get all the HP out of the truck that we can. Some trucks are able to maintain the commanded 29,000 psi, and others are not. You will lose quite a bit of power if you start dropping rail pressure.

At this point we are waiting for someone to come up with a modded pump for some real tuning.

This must be where the terrible Defuel is coming from, if a duramax is not holding rail pressure or not getting enough fuel sometimes they won't shift at all.

H&S What about a lift pump?? Won't this help his rail pressure problem??:confused:

A lift pump may help slightly, but I am putting my money on the high pressure pump that is falling behind. These pumps move a lot less volume of fuel than the CP3.

Hmm thats terrible news, your not gonna find hardly anyone that is gonna wanna tear into one of these things and try to get the CP4 out ot mod it:rolleyes:

13.8 with tuner and exhaust is impessive! I have lml with black max every once in a will under full throttle on hot setting it feels like it blows egr open? smokes and loses power. I have 7k with H&S tunner and love it but may need to block egr? I do not think i am losing rail pressure because of smoke? any ideas. Also seeing 1500 plus exhaust temp in hot tune.

Probably running the rail dry. It will smoke more when you lose rail pressure. Watch the ICP on the Black Maxx when this happens.

Thanks H&S. I will watch ICP. My have to try lift pump. I also have 14k on fuel filter my be the problem?

H&S what does ICP stand for?

It's not mine a customers Lml ill post some pics up an alligator makes a delete h&s is also working on one from what I gathered talking to them an ass for Fass they do just no instructions yet I'm just using a normal 150gph for a dmax an puttia draw straw hoping to make a solid 500hp+ tuck it's probably a 450 at the wheels truck now with the black Maxx an intake an exhuast just the way it feels yo me driving the truck

Does the Fass pump require a draw straw? Let us know how it all turns out I think this is the route I will be going with my truck as well, siince I can't leave anything alone:rolleyes:

I have no issues with mine, I am loving it actually. The truck sounds awsome.

According to Matt at alligator performance they have already put a Airdog on an LML. Matt told me that the fitting is fairly generic so the Airdog fit right in.
I too am looking at going this route. I just need to recover financially from the tuner and exhaust expense first. Next on my list-

-install turbo back exhaust
-Banks air intake
-Airdog
-EGR delete

So far, (still running in DPF) Im impressed with the Mini Maxx.... World of difference from the stock turd it was.... No issues as of yet...
Best part for me was I took the wife for a C&B over the weekend. She asked to drive for the first time so I said ok... what the hell, told her to stop on in and her face lit up like a Christmas tree.... her words exactly, " I knew you couldn't leave this thing alone"....:)

I was running my Mini Max for about a week on wild with dpf present.Then finally got the cat back 4in from flow pro.After i got it all installed turned up the mini max and Smoked like a train.lol, After doing alot of reading on the forums I deffinitley need the airdog lift pump.Some times if I boost it up hard from like a 20mph roll it will defuel. But if I get in to it easy then wot it runs perfect.I dont know if it is just mine does that are not.When I do a low boost run it pulls hard. H&S mini max is AWESOME

My cousin has a 2011 chevy pickup with the new 6.2 with a dyno tune and exhaust. We ran from a dead stop till about 110. I pulled him about 2 trucks.When we ran from a roll 20 tll 120 I got him about a truck in a half.Which is good considering he runs a consistent 13:70 to 13:90 in the 1/4 .If I could do a hard boost i probably pull him futher from a dead stop .

The defuel your feeling is probably the tuning. :(

It could be.... However I think its more the TCM defueling. According to HS I guess there is not much we can do about it... I'm still a happy camper though....
I am also looking into a airdog. My truck with the 4" AFE turbo back doesn't smoke that bad though... Not like I have seen on other videos with the HS wild tune.

cab lights YEEE-UHH

I have had zero problems with mine. Full 5" turbo back exhaust. I use my truck every day for work so I don't do anything stupid, like full power runs up and down the street, beating the crap out of my transmission. I normally run it at the lower setting, mild, especially since I tow so much. I like it for NOT having to mess with the DEF problems.

Almost 10,000 miles since I installed the tuner and NO issues with check engine lights, limp, ect.

Twister,
What kind of real world, hand calculated mileage gains have you seen?

Twister,
What kind of real world, hand calculated mileage gains have you seen?

On the road empty, averaging ~75 MPH, hand calculated is usually about 19.4-21.2. Sometimes slightly higher, sometimes slightly lower but I'd say averages mid 19's.

Nearing 20,000 miles on the truck with zero problems. The only thing you must be cautious of is when changing the settings and loading a tune. The other day I was getting ready to pull my 38' Raptor toyhauler and was retuning to the mild setting. About half way thru my cell phone went off, and as I have it going thru my bluetooth, it rang thru the truck. Well, the download stopped and got hung up mid way thru. I always turn the radio, A/C, and everything else off but didn't think about my phone ringing thru. Was starting to panic a bit and called H&S. They told me to shut the truck off and take the tuner out to let it reset, and put the truck on a battery charger. As I understand it, these modern trucks are very sensitive to voltage changes. (The battery charger prevents voltage from changing to much while the tuner is doing its thing. Too much voltage drop can cause the same problem as the phone ringing.) When the call came thru, the ECM opens a program for that and in turn the programmer goes into a safety default mode. Anyway, to make a long story short, reconnected the programmer, it came up that it had detected a fault and was returning everything to stock. After it did its stock programing, I then reloaded the mild tune and all was good.

Lesson here is that I now shut my phone off, as well as everything else, whenever I need to change the programming. (Probably need to shut that da*n thing off more often anyway!)

Matt

Thanks Twister. What were you seeing prior to the delete?

16-17. I would start to see better and then the da@n thing would go into regen and drop like a rock.

I have no doubt I could do better than the 19 or so I'm getting now if I'd slow a bit.

Thanks,
Matt

I hope I see gains similar to yours!

Hey Matt.. What tune seems to work best for you? I am stuck between mild and wild.. My week is mostly in town driving, and two trips to Church evey weekend, 60 mi one way on the hwy, so thats 240 mi hwy all together.. 80 mi during the week in town

I generally have it set to mild because I tow a lot at work. Like the power of the wild setting but afraid I'll damage the transmission towing heavy at that power level.

Matt

Oh and one more thing I like the looks of my new LML
It sweet that a 4x4 with 285/55/20 sits as low in the front as my 2010 2WD race truck that has DJM 5" Drop beams. That is another reason why I went to a GM. I hate lifted trucks and wont be beating this thing down lease roads so lower the better.
Here is a quick vid of it from 10 minutes ago.
I learned to put the truck in manual on the hiway so it stops downshifting like a 6.0L and it actually pulled some nice speed. Its dangerous in auto because it cuts the power to downshift so you never know what the truck is going to do when you pull out and mash it. Putting it in manual fixes that
I would like to do some burns out vids but am still learning how to drive around the defuel. I will keep practicing :)

Love your truck man, seriously :D you said that you have 285's in your post but if my hearing serves me right it sounds like you say 35/55/20.

Its time to set me strait here, what is it?

twister- what do you get towing?

Sent you a PM

My latest trip, 1800 miles from TX to MA this past week went like this.. Had 2 heavy adults(its true), 3 kids and a dog, back of the truck and tool box was loaded full.. Drove about 75 pretty steady the whole way and averaged 19.6 on the first fill up, 20.6 on the second fill up and 19.2 after we got here and drove around some, that includes about 200 miles of city driving when we got here. I think that's pretty good for a 2500 crew loaded up.. Have H&S on wild setting, and 4 in' cat back exhaust. 8,000 miles on the truck since I installed the tuner and exhaust with no problems, wild 90 percent of the time. I do all of my mileage calculations by hand every time and my life time average after the tuner is up 1.2 mpg and will continue to rise, thanks H&S!!

Thank you for the info maddjohny.

I have a 3500 Denali Dually, getting much worse milage that that with the same mods. I'm waiting for an email from H&S to see if there is something a miss.

Again thanks for the info!
