Just thought I'd start a thread for those who purchased this tuner (for the 5.7 Hemi) to post their thoughts/impressions on it.

Interested in some dyno runs or vids too. As much as I trust each of your butt dynos, would love to see some additional data to support the 30hp/tq claims.

So I got my inTune last night. The install went pretty smoothly. One bit of advice: remove the starter button and use the key to cycle the ignition on and off (as-required any time you do anything with the tuner). When the tuner first did the copying of the factory tune (and I had the starter button in), it prompted me to cycle the ignition off and on. I tried to do it, but nothing happened. All I had were a bunch of warning lights frozen on the dash. It eventually worked like normal, but I definitely wouldn’t want anyone else to risk the immediate heart stoppage I almost experienced.

My first test was with the 87-octane tune and 10% throttle boost. Test drive impression: you could feel the improved performance when really giving it hell from a stop (on a closed-course, naturally), but there really wasn’t much difference around town. The throttle boost was slightly noticeable, but not like on my old ’10 GC SRT8. That felt like it would put you through the back wall of the garage just pulling in the driveway.

My next test was with the 87-octane tune, 15% throttle boost and raised part-throttle upshifts (I can’t remember the number, but it was the first setting). Test drive impression: you could feel the improved performance when really giving it hell from a stop, and out on the highway, but there still wasn’t much difference around town. I definitely didn’t like the part-throttle upshifts. I also noticed that MDS seemed to kick in a little more. I read somewhere, either in this forum or on the Diablosport forum, that the more active MDS could be related to the part–throttle upshift adjustment. MDS doesn’t really bother me, so I don’t care much about that, but I definitely didn’t like the upshifts.

My final test was with the 91-octane tune, 15% throttle boost and stock upshifts. I had a half-tank of 89, so I filled up with 93. My impression: I now feel better about having dropped almost $400 on the inTune (I was starting to have concerns). You can definitely feel the difference on takeoff, on the highway and around town. CMR is where it’s at though, so I’ll be e-mailing Johan for a custom tune as soon as I get an intake.

Final thought: my first introduction to Diablosport was on my old SRT8 with intake, t-stat, x-pipe and CMR tune from Johan. The truck felt like a rocket, and the tune made a night and day difference. You’ll never get those same results on a ’12 5.7 with a canned tune, but the tuner is still worth it IMO. It is not, however, a cure for the woeful factory transmission programming. It just makes it more bearable, and gives you some added performance to boot.

Final tip: I ordered my inTune from AutoAnything. They’re always running a 10 or 15% off special, and free shipping, so my total price was $381.65 (down from the $449 mrsp). I ordered it on Monday and received it last night.

Great review thanks!

How long does it take to go between tunes? I probably wouldn't want to use 91 all the time. Part of the reason I bought the GC was the ability to use 87. Then again i'd probably run the 91 most of the summer and switch back to 87 in the winter when my driving is less aggressive.

Thanks

It only takes a couple of minutes to switch tunes.

This would be the best outcome...hopefully someone out there with a tuner can run their JGC on a dyno...but I'm also in the belief that the company producing the tune should be providing these as well. I know HP and TQ improvements are not all that this product is expected to improve, but it's good to see lofty claims backed up by data.

i also have the 93 octane tune, but i'm using the trinity. It's definitely the way to wake this truck up. I can spin tires accelerating from a dead stop , and dang it feels good to screech! :lol: I can probably post a video soon if the weather permits.. Of course the snow decides to come down as i type this post! The throttle response is well improved, and my Jeep finally knows what gear to fall back into for an enjoyable acceleration! From my experience, previously being detuned, accelerating from say 40 mph and getting that "umph" was quite difficult. Now she purrs like a dream! Again, i'll post up a video when the snow settles down (according to TWC, it's snowing for the rest of the week). Oh, and i forgot to mention, apparently the tune keeps the ABS light on, and it's currently being reviewed by Diablosport. Though it annoys me, i'm putting up with it for now until a new update comes out for the tune. In the mean time, i'm going to enjoy messing around with no traction control in the snow. I mean, can you blame me? :thumbsup:

Hi! No I haven't fiddled with the tire size program yet, I would imagine it'd be really easy especially since it's in the quick adjust menu alongside the traction control program. (At least it's that way on the trinity, it takes only like 20 seconds to adjust something in the quick adjust menu) so I'd think it'd be something very quick to adjust. And yes, I couldn't help myself but to raise the speed limiter all the way up (to 140). I probably won't ever attempt to hit that kind of speed, but you never know, things happen :lol:

Hi! No I haven't fiddled with the tire size program yet...
You may have accidentally hit it in the quick adjust menu. Otherwise you'd be the first I've heard to have gotten the ABS light without changing the tire size.

Really? I'll check it out later and update you guys. It's possible that anything adjusted in the quick adjust menu would trigger the ABS light. I say this because if I turn traction control back on from the quick adjust menu, the ABS light goes away. To my understanding, it occurs with traction control too, not only tire size. It would depend on whether or not you played around with your traction control settings or not... Again, ill double check!

OKAY! I did a little more digging and I found the reason why. On the trinity, you have the option to turn off ESP (Electronic Stability Programming), and this would inversely turn off ABS as well... I'm not sure how it is on the intune or if you have that option, but apparently that's what it does according to Diablosport's website. I THINK this is only on the trinity because I think that disabling traction control on the intune doesn't disable ESP. That would explain why I have the abs light on. So, it looks like that's supposed to happen. Ill quote diablosport and what they have to say under the trinity's adjustable parameters section.

""Selecting the "Disable Traction Control Parameter" will disable the ESP and ABS systems completely for use on the dyno, at the drag strip, or even a road course.""

Looking at the website, I don't see that the intune disables ESP. So I guess that would explain it. :D

Interesting...thanks for the info.
 
#73 ·
Yes, give it a try. I know that when I enable traction control under the quick adjust menu, the ABS light goes away.
 
#74 ·
Do you mean whether or not it times my 0-60? Yes. It times 0-60, 0-100, 1/4 mile, and 1/8 mile times.

Post a video of it! It's easy. Point the camera at the speedo. Say "Go!" and hammer it. Then post it on utube and link it here. The video has a timer on it. We'll see just how fast it was.
I can't believe everyone will spend this kind of time, effort and money into doing this, and not find a couple hundred bucks to get get a dyno test to see what exactly the differences are. I mean even Diablo should be producing these to show you what your paying for. Any Mustang Dyno that is certified will work great. All these pages and talk, not a single dyno sheet.

I can't speak for anyone else, but I can't see the point of dyno testing my Jeep. I've done it on other performance cars I've owned, but in this case I see no reason to. I wanted better acceleration, shifting and throttle response; and I got it. Why spend another couple hundred bucks just to prove how much better? That's a couple hundred bucks I could put toward something else, Jeep-related or otherwise, rather toward a dyno sheet that I can use to satisfy someone on a forum. If you think a tune may not be worth it, don't spend the money. I thought it was, my thought was correct, and now I'm a happy camper. I don't need a dyno for that.

I'm curious what sort of impact everyone is seeing to the fuel economy?

I got my InTune DCX last week and after running several days worth of updates (intune.exe) finally summoned the courage to plug the tuner into my 2011 5.7 Hemi GC. Once the PCM calibration update was installed, I had several options and decided to install the 87 Octane tune, adding 5% throttle boost. After several days of driving, I'm very happy with the improvements in driveability. I've noticed a substantial improvement in power delivery over stock while running the lower octane fuel rather than the 89 that I have been using since taking delivery.


Anyone else start with the 87 octane tune or does everyone jump right into 91 or better?

With the InTune, do you have an lcd screen to mount or is that the Trinity only?

Can you guys post up pics of your mounts?
 
#83 ·
Not really mountable unless you want to put it in a phone mount. The screen is small though and would be pretty hard to read on the fly. It's just a small hand programmer that easily fits in your pocket. I have been keeping mine in a neoprene sunglass bag in the glove box with the cable. Until I trust it I figure I should leave it in the GC in case I need to flash it back to stock for a dealership trip.

Makes sense. Custom tunes are generally created based off data collected from that specific engine. One persons perfect tune will likely be not so perfect for another.
