Stacked Tuners

[Wild one]

Is anybody running a HP tune stacked into their Diablo tuner?

 

[Kotta390]

What advantage would you benefit from this?

 

[Wild one]

The ability to switch from a radical HP tune and good fuel,to a lower grade canned Diablo tune that uses a lower grade of fuel is sorta my understanding.Tonight is the first I've ever heard of it,trying to do alittle digging on it,as on paper it sounds good.

You can have the best of both worlds on one tuner.

Just get a custom tune for the Diablo.

I've yet to see even 1 12 second Ram running HP tuners. I would stick with what is proven and what is working very well in these trucks...Diablo with a custom tune.

Anybody see the fast n' loud show where they put a hellcat motor in a old dart? They couldn't get it to start cause the computer needed some work, they called the hp guys and they couldn't figure it out so they called the diablo guys and they got it no problem. That was when I saw Diablo is the **** compared to anyone else.

I saw this episode. Perfect side by side comparison. HP had every advantage getting first crack at it and Diablo still won getting it to fire. Then they proceeded to change injectors, up the boost and tune it to run on E85. Nobody out there can touch Diablosport tuning a mopar.

That wasn't the question boys and girls,i've ran both and both have their benefits,what I want to know is how much more can be gained from stacking them as one tuner has succeeded in doing.

Nothing to be gained. It will only cost you more money to have a big pain in the butt. The tunes get overwritten. If you get a custom cmr tune on the Diablo tool you can switch tunes and set it back to stock with one device. There's nothing that hp does that can even compare with a Diablo.

HP Tuner and Diablo stack works well and allows more performance on some models.

Still prefer Diablo in most cases and if needed only use the HPT for parameters Diablo doesn't. HP has more parameters on the engine side in most cases. But Diablo is simpler to work with.

Soon you will see HPT start gaining ground. And yes I could easily take a truck with a solid setup and make it run similar times with HPT, anyone that says otherwise doesn't know what he is saying.

I'd love to see another viable option for tuning. Doesn't seem as if anyone has had any success competing with Diablo though. We've been hearing the same song and dance from hp for a couple years "soon they'll gain ground". When does soon get here? Also, what does similar times mean? + 0.02 sec? + 0.20 sec? + 2.00 sec? Problem is there's still a plus sign in front.....until they can get a minus sign out front they will still be second rate.

For the op, if you want to run a simple canned tune for cheap fuel and have a "race tune" to be a weekend race warrior you can do that with one device. If it runs on a canned tune you're overthinking the tuning for your mods. Your money would be better spent elsewhere to make the truck faster. My 2 cents, take it or leave it.

That's exactly what everyone is saying. They are real close but not quite there.

DSP really has some crappy customer service sometimes so you have to weigh that in too. It took them a week to get my trinity and truck reset after the tool somehow reset leaving it unmarried and a tune on my truck.

For what the op seems to desire stacking tuners seems unnecessary. Don't doubt it works but for the hassle I personally wouldn't do it to anything other than a dedicated race truck.

Say you get a recall notice. It's not unreasonable to think you could spend 20 minutes on both sides of the appointment tuning. Forget to do that and the dealership flashes an update on you then you've got 2 expensive paperweights to unlock. Not worth it IMO.

Just to clarify.

I have a 2015, and a new (unlocked) PCM. It was my understanding that all I needed to do was swap them out before going to the dealer. Will I have to have the tune redone if they do an update?

 

[Wild one]

Jay I was privileged to see your video,i want that flipping shift you have figured out.That's the quickest damn shift I've seen out of the 8speed,very very impressive

 

[StoneDude76]

Not to get off topic but who can program the 8 speed tranny? HP?

If anyone will figure it out it will be jay. He tests and beats on his truck everyday for all of us to benefit.

If you swap pcm you're golden for dealer work. The only reason you would need to do that is if you wanted the update on the tunable pcm. Say a transmission update came out. I believe diablosport buys the factory calibrations and makes them available to load with their tools.

I was making a point, why put it on a good programmer when apparently hp hasn't quite got they're **** figured out yet.

So if something needs to be updated on my tuned PCM I would ask Diablo if they have it, then get the tune loaded to the Trinity, download that tune, send to HF, have them apply my tune to the factory one, and reload it?

Just trying to make sure I understand how this all works. I'm from the time when tunes were done with a wrench and screwdriver...

For a dealer trip all you have to do is put the original locked pcm back in the truck. If a transmission update becomes available and you decide you want it all you would have to do is use the diablosport tool to set the pcm to stock. Plug the tool into your computer and update to the latest crom which should have the latest pcm calibrations. When you go back to the truck it should update to the latest calibration if there are updates and once that is done just put your tune back on and go. No need to send anything away. DSP tech support can answer questions better than I can and they can walk you through the process if it ever happens. You can also decide that a pcm update isn't needed and leave it alone.
