2014+ Engine & Transmission Tuning

[Jon A]

Jon A. Has been playing with his as well and may have some more 6.2 pointers. Jon seems pretty sharp.

 

Thanks, but not sharp enough not to need some tips from time to time! Anyway, I will post up my tune when I feel it's more of a finished product.

Just talk with you service person and be upfront with them I've had nothing but great service with these guys and I had a tuned truck/trucks. Every brand of truck from Dodge, ford, Nissan, Chevy anD GMC they all say the same thing. Oh the tuner will void your warranty. If Your upfront with the service person and talk to him or her before You get the tuner they usually tell me as long as I don't bring it to them tuned they have no problem with it.

TDT can you email the file as well. I have HPT as well and am about to the point of looking into tuning mine.

Where do you want it sent to?

So who here has bought the Range V8 unit to disable AFM? What are your thoughts after using it? I don't want to do a full tune while the truck is under warranty but I've been considering this unit since it flies under the GM radar.

I used the Range unit for a few months. Its ok, gets the job done. I actually just sold it though. And I am considering a custom tune.

 

Comparing the Range unit to a custom tune, is like comparing a bb gun with an assault rifle. Sure you can hit the target with a bb gun, but you can blow it away with the rifle.

 

Go custom.

Yeah I remember reading you were getting rid of it. I don't want to go custom because I don't want to void the warranty and the stock performance doesn't really bother me other than I don't care much for AFM and the hesitation in performance when it needs to switch back to V8. I miss a nice good old stock Chevy V8 engine along with that old stock throaty exhaust sound.

 

 

EDIT: Disregard these posts. I realized there was a thread specifically for the Range V8 and I have posted this question there.

Is anyone running E-85 on the BB tune? I talked to Justin yesterday eve and he said that he is going ahead and improving all of those tables as well on the tunes he is completing. I plan on trying it out and sending him another log to see how it acts. Anyone have experience with it yet?

Hi Guys, Diablo emailed me this morning to announce that they've got their tuner units ready for the 2014's, here are some of the options it does, I've had a Diablo for my 2010 Denali since I purchased it, but back then there were a lot fewer things supported than they appear to be doing now (primarily purchased it to change the tire sizes and disable the limiter)

 

inTune really improves the 2014

GM Truck; tunes included are 87 octane tune, MPG Booster Tune, and the Diablo

tune, which should be used with octane higher than 91. Increases of up to 15 hp

and 20 ft lbs of torque can be seen across the entire RPM range with

the Diablo Tune.

Our tunes are calibrated specifically to improve performance,

drivability, and economy and reduce the factory's power-robbing "torque

management" to put more power to the ground when you need it. Other

options include TCM (Transmission Control Module) control to adjust automatic

shift characteristics, DOD (Active Fuel Management) disable, speedometer

adjustment for gear and tire changes, and raising speed and rev

limiters.

 

 

 

So I received my Diablo Trinity in the mail very excited.. spent more than a few moments at my truck with failures each time followed by 20 min holds with Diablo, followed by another attempt...FAILED. I got to the part where it wants to save your factory tune and it refused to do so. Diablo asked me to get them a bunch of numbers off the trinity (it does connect to my engine), and I am now waiting for an engineer to figure out what the deal is.

 

Anyone else have this problem, or know what the solution is?? Worst part of it is that my Gibson duals, and my K&N will be here on Tuesday and I was hoping to see what all would happen.

 

Like most of you, my mileage has been horrific since I bought the truck.. i mean 11 city... 16 highway (downhill)

 

Love to hear your feedback

I'm not sure exactly what you are looking for but east coast supercharging ( eastcoastsupercharging.com ) does a lot of bad ass cars along with race proven motorsport which I believe have their own website as well. If you are mostly stock you may be just as happy with Black Bear who is a sponser on this forum.

Bought the diablo trinity, but can't seem to get it to work..

Just curious, is your trinity updated? Very important to plug it into a pc and run updates. I have an intune, had a similar issue until I ran the updates.

Update on my intune diablew tune:

 

I've been trying to isolate a backfire issue at WOT when the truck shifts. I've noticed this since I had the third cat removed. My conclusion is that it was doing it with the the third CAT, just not apparent.

 

Lew is stumped, we're still in the isolating stage, but I'm getting frustrated and about to pull the plug on the intune and purchase HP tuners.

 

Other than the backfire at WOT the truck runs and drives awesome.

What do your fuel trims look like right before the gear change? Sometimes if you are holding fuel too long when you come off of throttle you might have some backfire-ing.

 

***You are right though, the truck might have been doing it before...but the third cat was "catching" the mixture.

 

What I would do is check a datalog of right before the gear and then during the gear change...(Livewire you would've been looking at gear commanded and actual....then timing, fuel commanded (lambda), and actual (Lambda), rpm, and maybe actual throttle blade %)....I di not how the Diablo stuff logs.

 

On WOT you should see .78-.80 ish Lambda (everyone has an opinion but closer to the .80 w/o detonation makes more power--.78 is safer).....if you are too rich .77-.76...you should have the fix easily, just lean the fuel out right at the gear change over.

Thanks for the insight. Lew tells me he's tuned 40 + 14 Gm trucks and first he's heard of this. Can't seem to get it to subside. I have gone so far as to install the 91 diablo tune (not adjusted by Lew) and it still does the same thing (ecm), no change to TCM. I've yet to return it to stock tune, but that is in the plan. If I get time to day, I will do some more screwing with it. I think my next step is to load different TCM tunes i.e... stock and diablo leaving the ecm tune alone and see if it's something in the TQ Mngmt.

Its been a few years since I messed with a can tune but I had a problem once where you could raise the shift point higher than you could raise the rev limiter, that would make a pop till I lowered the shift point a little.
