the death of the dmax

[Monstr913]

You know, i have a pretty good amount of experience with both EFI and HP tuners and I have to say that im not a fan of EFI. HP tuners just has such a better layout and is much more user friendly. EFI is pushed very heavily in the diesel community though, unsure why. Seems to be a far inferior product in my eyes. If you ever have a chance to us HP you may never pick up that EFI handheld again!

hp tuners is gauged more for gas application and efi live is more for diesel they both work on either or but the tuning is better for one and not the other...i've seen efi and hp tables and there almost identical from what i've seen...once i get my truck back i plan to go with efi live as im not sure my other tuner will be enough anymore

To comment on the bold part of your response. They reason that HP tuners is "guaged" towards gas and EFI towards diesel is because that is the way they are marketed. EFI was marketed to the Diesel guys and HP to the gas guys. Both tuners are able to tune the exact same parameters so neither is actually a better tool for changing the tune on a diesel or a gasser. The ability to change the tune is the same with either product. Thats the bottom line on that.

As far as having more options for live datalogging and how user friendly the software is though, HP tuners wins hands down and IMO is a much better tuning tool.

Im currently on my 3rd Dmax truck. Ive had a LLY, LBZ, and now im on a LMM and will be purchasing a LML as soon as they hit the lots. The LLY and LBZ I tuned using EFI. Then after talking with some people who owned HP tuners I was very easily persuaded to switch after seeing how much easier it is to work with. So far I have used HP on the LBZ before I sold it and the current LMM truck as well as quite a few of my co-workers trucks with great results. I will never use EFI again and if you would like to buy mine from me we could work somthing out.

Take a look at HP before you pull the trigger on EFI, its cheaper as well.

it was originally developed for gas applications then was brought over to diesel and vice versa for EFI live. EFI Live has better support and marketing for the duramax....its like vhs vs. beta...it may have been technologically better but people didnt buy it and it died. its a popularity contest. SInce EFI live was out first it has a TON more available tunes

I will agree that it has better "marketing" for the duramax as the owners of EFI are supporting vendors on many diesel based websites but as far as better support, that is a wash between the two. EFI definitly has more available cookie cutter tunes available though, this is true. But do you really trust someone elses tune in your 40K plus truck? I wouldnt, every aftermarket part combination is going to react different to it. So unless you plan to just use someone elses claimed "safe" tune, HP and EFI will both get the job done. It really comes down to personal preference.

And since I did comment on genaric tunes and I dont want tuners such as bullydog or PPE being thrown in my face as far as them being safe on peoples trucks regardless of other mods. These handhelds go through a serious amount of R&D and are not pushing the trucks to there ragged edge. They are tuned to run within safe parameters so that you dont melt your engine down. Now your transmission on the other hand... Say goodbye!

[WickedSix]

Its hard to kill the allison.... the truck above put down ~500 rwhp ~1000 ft-lb with the box sotck transmission that has been drag raced sled pulled...and just generally beat the piss outta... i wouldn't of believed just how resilant they were if i hadn't seen it myself.

As to the tunes I wouldn't trust joe blow who wrote a tune and posted it on the internet for free. I would however trust the guys who have put countless hours into their own tunes who have had similar combinations in pullin and racing. The unfortunate thing is PPE hot+2 has beat every other tune out there for a stock turbo stock internal truck whether it was hpt or efi live from what I've seen. So why would you buy either EFI Live or hptuner if you are using a stock truck and not trying to get it to the ragged edge?

[emptypockets]

Last thing I want to do is get into an argument here with someone I dont know as im not the type to cause turbulence but 500rwhp in front of stock allison is not the norm. If you go over to dieselplace.com you will find that just about everyone starts to have trans issues at about 100rwhp over stock power and if someone were over there flapping there gums about a 500rwhp truck with a stock trans racing or pulling they would get laughed off the board. Could it be a factory freak, sure sounds like it since its legit but its not somthing that seems to occur to anyone else that ive ever talked to. All three of the dmax trucks ive had were purchased new and all three ate the stock transmissions at about 450rwhp. Ive become quite good at rebuilding them! (with suncoast parts, makes a ROCK solid trans). 500rwhp is very easy to reach with these trucks, but as ive learned there are some serious weak links. The stock transmission and the pistons/rings are a couple.

PPE is a great product, no doubt. But ill stick with the ability to taylor my tune to my liking over a cookie cutter tune. Not to mention I can and do make way more power with HP.

eh our trucks run gale banks tunes ne way

Although Banks products dont make a shit ton of power, they are very well designed and probably have more R&D time into them then any other product. I know quite a few guys that are very happy with there banks products.

I've owned my HP Tuners for 5+ years as well.

i like my ppe. but the support for efi live in the duramax market is so abundant it would be hard not to go that route.

[WickedSix]

i forgot about the bonus of the dsp 2 or 5 switches which allows selectable tune on the fly whereas hpt has a big ole goose egg in that category

[BAD LS1]

EVERY vehicle i encountered tuned with EFI needs to get the PCM flashed back to stock by a dealer before HP tuners can even get into it. It corrupts the PCM with a really weird OS that nothing else can do shit with, pretty gay.

[WickedSix]

Just as an aside, how many of those were gassers? I haven't seen too many people embracing EFI live for them.

[BAD LS1]

None were duramax trucks, but ive gotten the pleasure of 5 and counting since ive started on gas vehicles that needed the flash back to stock after EFI live treatment. Not sure if its the same for the d-trucks, but dont they run a Bosch PCM too?

It is the exact same for the Dmax trucks. Same problem will occur. This is yet another reason I do not like EFI.

[Anakonda69]

most dmax trucks that go as far as needing efi live most likely won't ever need to go back to stock pcm. i think as far as d-max's go efi's pro's far outweigh the con's.

[lilws6]

whats a ppe? i'll probably be looking at a programer soon. i was looking at getting an edge just since my buddies got one and i like what it shows on the screen especially when the speedos crap out. but is there something better for the money or would the edge be fine for me i don't need to do a stand alone ide just fuck shit up and make it smoke alot

[lilws6]

nvm googled it i like the on the fly thing of the edge tho

[Anakonda69]

ppe is way cleaner tuning then an edge but just do some research and see what works best for you.

[Monstr913]

i ran and edge on my truck was nice for tuning on fly. then i stacked a predator on top of that and was better. then i bought my first PPE way cleaner and truck handled a higher tune from that one tuner then the double stack...as far as efi being better then a PPE, thats debatable in stock application...i have a good friend that ran his truck on dyno with a PPE Hot+2 E.T. vs. a custom EFI (made by McRat racing) and the PPE made more power only by about 10 hp, but still...also i got a friend with efi and we have almost identical mods and at Huckstorf Dyno last fall i made 508hp 1003trq (stock trans) and buddy with efi made 516hp 985trq (iirc,stock trans as well) and that was a custom tune made just to try and beat me...now if you got a full built motor custom tuning all the way, but with stock turbo and internals your pretty limited as to what it will make/handle...as for anyone that doesn't believe what my stock allision has been put through i will gladly show you 3 dyno sheets proving it and video from GLD so you can hear what it did...i speak past tense as i will have my truck bad tomorrow from a full trans build
