DiabloSport Tune review FAIL BEWARE

Hey guys I thought I would give a review of my experience with DiabloSport.... It didn't go well.

I ordered a tuner from Quadratech. It came quickly and I was exited to use it!

I have a 2014 JKU sport.

I wanted the tuner for the HP

So I followed all the directions to a tee. I plugged it into my computer and loaded the updates. This took a very long time. This is already when it started going bad. The diablo tuner is EXTREMELY delicate, internally and externally... If anything pops up on your computer while the device is updating it will cause it to NOT RESPOND. This happened to me 3 time for things like norton popping up telling me to update soon and other things like that. Each time I had to completely restart the update process.

after an hour or more It was done so I drove to the gas station to fill up with 93 octane. I filled up the tank and decided to do the tune right there.

This is when it failed. I got some errors while it was trying to copy the back up info.... ok sweet. tried again... nope...tried again.... nope fuck it I'm hungry

So I drove to Culvers for a burger. I got cheese curds as well. The food was excellent as always..

while eating I was like... ehh I'll try one more time.

Plugged it in
selected tune
it started writing the back up files... and it worked! AWESOME! time to load the new tune.
loading loading loading ERROR
NOOOOOOOOO
device will now restore original tune
loading loading loading ERROR
NOOOOOOOO
tried three more times
Tried to start the jeep...............nothing she was dead
So I had to get it towed and take a cab for two days. this happened on a sunday.

I emailed Diablo sport. no apology, just told me to copy some attached files to the device and try again.. umm NO

why weren't those files included in the first place if thats what I needed...

The dealer was able to "flash" the jeeps computer to bring it back on line. They asked if I was using a performance tuner to which I lied and said NO because I wanted it to stay under warranty.

THANK GOD the device didn't leave any traces.

Quadratec was very apologetic and offered to pay for the rerun shipping, thanks guys you are great!

Diablosport didn't seem to care much. You guys could at least pay for cab fare!

So Im worried this produce is not ready for 2014's.

I will not use a diablo device ever again. If any of you do I suggest you do it in your dealers parking lot so you don't have to pay for the tow truck!

I had the Diablosport Predator for my 300C Hemi and it worked flawlessly, but there have always been some that have had issues. I use the AEV ProCal for my Jeep as I wanted a simple device to change tire sizes...etc etc, but did not care this time around for a performance tuner. Hell 87 octane gas is $1.30 per liter ( $5.20 per gal) here in Ontario Canada and 93 is at least 15 cents more per liter, so the heck with that...lol

yup, Had a buddy brick his with a superchips. it ended up not being their fault but they helped him out greatly. they paid to overnight his ECU both ways to put a stock tune on it, the problem ended up being inconsistencies in the pins on the connectors in the 2014's and superchips was well aware and was working on a fix.

I have a serious question, forgive my ignorance in this area. Why would you attach a sport tune to a Wrangler?

People seem to think they can 'improve the performance from factory'; which is a myth propagated by the companies that make these things. They ignore the facts that the factory spends thousands of hours and millions of dollars tuning each line of vehicles to get the maximum balance of efficiency, power, and endurance. Most chipsets/tuners just dump a crapload of fuel into the engine; then people wonder why their engine blows itself to scrap before its next oil change.

If one needs a programming chip for driving in high altitudes; thats one thing - but most of them are a joke, waste of money, voids the warranty if Chrysler catches you (and, yes, actually, Chrysler CAN figure it out) and the net benefits are simply not there.

Obviously; I dont like them.

Yep, I'm not shocked here. I installed the Diablo Trinity on my 13 Charger R/T, drove it for a few months, all was well. I was trading my Charger in for the Jeep so I went to remove the tune, and guess what! I bricked my ECM. So, around $500 later I had the car running and traded it in. I will never, ever, use a tuner again. And this is coming from someone who has used tuners on almost all my cars. Very common problem with Diablo and Dodge Chargers.

Diablo has royally screwed up a lot of people's jeeps. We have a thread in the technical section involving RIPP superchargers. Diablo has been ruining a lot of people's rigs. I'd stay away from their tuners until they get their sh!t together.

beta tester for diablo here. those files are for only when a machine encounters an error. not all computers are the same and you will tons of errors. your best bet is to contact them on their forum. unlike the other companies they have a ton of diehards that can help on there. more often than not its something simple

I bought the Diablo for my 2013 Wrangler. No issues so far. I don't know if "optimizing" it for 87 gas actually did anything, but I was able to set a better responsiveness for the gas pedal. There isn't as much lag anymore when pressing it. I plan on keeping this thing until it dies hopefully in 20+ years, so I'd say the $375 I spent will pay itself off over the course of the next few years.

It's too bad that you have had such a bad taste of the aftermarket tuning experience. I swear by my SCT tuned Ford. I haven't tried one on my Jeep yet but at this point it looks like the Superchips tuner will be the winner.

Forums like this are great places to research the trials and tribulations of others like you that dare blaze these new trails. Would you mind expanding on your reason(s) for being such a tuner hater? Vehicle and tuner details might help the rest of us.

Thanks!

I've been using diablo on my srt4 for the past 5 years, and it has been tuned, retuned, and tuned over and over again. Never once had an issue with the programs or the unit itself. Biggest thing with diablo is to make sure it's updated, I think the papers tells you to update before using it

To clarify my point above, research your choice of tuners. It seems that each company does one manufacturer better than others. They may have an insider in GM, Ford etc. Or they may just like a particular brand. I think that SCT is the king of Ford tuning on my particular model but I would purchase the Superchips unit for my Jeep just based on what I've found out so far. I already own an AEV ProCal and it is a GREAT device if all you want to do is calibrate for tires and gears. It is NOT a tuner but it will fill the needs of most people on this forum for modifying certain parameters.

Sometimes one company may beat the others to market in "busting the code" and the others may just throw something together to try and take their share without really being ready.

Research...research...and then research some more. And be sure that the company you do buy from will stand behind their claims. Keep in mind that most Jeepers are not looking for max power output but good torque and overall drivability. If you are looking for max power you're driving the wrong kind of machine. I would suggest a new C7 Vette. That thing is AWESOME!!

You are playing with the computer of your vehicle. Things happen and life is not always perfect. Doing a tune for the first time while on the fly is not very smart. Once you have it loaded and working that's what its for. My dealer reflashed my car after I was in for an oil change when I had a tune installed. I told them no reflash but the tech never saw the note. Lucky it ran but my turner locked up. I was stuck in stock. Had to send files back and forth with Italy for 4 days to get it working. I ran a tune on my Turbo Mini and currently on my Ram Diesel. Works great on engines that need boost. The truck is sick in the Crazy Larry setting and the MINI was a beast with the tune running. I would have sold it years ago if I had to run it stock.

New Zo6 is even hotter. Starting Maxing out my GM card lately for the rebate, lol. I have had a Maserati GT Coupe I bought used with 10k on it about 5 years ago for 40K. I have about 10K into it with Exhaust and wheels, etc. Has 40K now and I just can't sell it yet event though I have 2 buyers fighting to get it at 32k. Just been to much fun and it has been rock solid reliable. Went on 300 mile run to Vegas a few weeks ago. Ran into major sports star in his 650i BMW on the way which led to a little paly time in the desert. 4.2 L Maserati/Ferrari naturally aspirated rated at 390HP- I figure closer to 450HP now with a few mods vs. 4.3 L twin Turbo rated at 445HP. Should be pretty close I figured with the edge to the BMW. He took a run at me cruising in the 90's. I dropped to 4th and by 120 left him in the dust. He settled in for a bit until we were all alone again. He put the hammer down and was coming hard now. I let him pass me and show me the his tail pipes before I dropped 2 gears running 100 into 4th. In my manual trans coupe 4th is 1 to 1 and you are hooked up the the electric locomotive at that point. 4th gear is good from 50 to 150mph depending on the r's. 120 to 150 seems faster than 70 to 100 because of the gear. By 120 I was gaining and walking on past pretty easy. By 150 he was fading fast and content to follow me to Vegas. Just hard to sell a car with soul like that. It is also the fasted I have even been in a car and that includes many race cars lol. 177 on GPS and still running hard. Car was loaded with clothes and as heavy as it has even been. 150 is usually enough but out on a lonely 2 lane cruising at 100 and 10 straight mile in front of me who could resist. Dropped to 4th and up shifted to 5th around 140 building speed. When I looked at the GPS 174! I held my foot to the floor wanting to hit 175 but ended running to 177 she was pulling so hard before I lightly lifted and slowed her down. 185 to 190 is doable with light load of fuel. Hard to sell a car with those kinds of memories. Owned a z06 but I was only to the 140's on a track with it. Had a 1995 Pontiac Firehawk that hit 157 out in desert but it seemed like 200 in that car, lol. Windows started to get sucked out over 155!

simpley to make up for some list performance due to mods and correct settings. I run SC to change tire size, lower pressures sensor threshold, dogs on on hi and a multitude of other stuff, but mostly for some added power back after lifting, bigger tires, and heavy ass armor. After tires and lifting mileage dropped to 13, put the SC in, corrected tire size and now have the feel back of stock power. Not downshifting all the time to maintain small his and headwind. AND BACK TO 17+ mpg.
