Is this available for the 2012 yet?

It is but I've heard it has issue with the 3.6 might want to check their web site to be sure

So let me ask, I just traded in my 2010 sahara for a 2013, I had Nitto 285/60 r18 with sensors on the 2010 and I merely transferred them to the 2013. within 20 miles the TPMS lights went off the charts. Anyways I have a Flashcal superchip which I adjusted the tire pressure to 0, turns the tire pressure light off, but does not disable the TPMS all together, u still get the 4 tires with 0 tire pressure on them every time you start the car. I'm assuming I need upgraded sensors , bit the tires are in great shape, I would take them off every winter and put the factory ones back on, its not economical to buy, install and mount 5 new sensors for like 200 and change at least for now. So does anyone have experience or can guide me for some basic questions.
1) can I use the FlashCal to disable TPMS all together, reset it and make it not show up as an error.
2) The axle ratio standard was 3.72 should I also adjust that lower to like 3.50 for the bigger tires and will that give better gas out put/performance etc or should I leave it at 3.72. Just trying to figure out how to keep the great look and not have to spend a ton of money with all new sensors and impact the performance.
Thanks

I get about 1 mpg better gas mileage running my Superchips in 87 tune. Tested it several times. Better throttle response also. Don't regret getting mine.

I run a flashpaq on 10 rubicon with 35's and get better mpg than stock...throttle response is better. A cai and exhaust made it much more responsive though. I run 87 performance tune.

Been running the 93 octane tune for over a year. Heavier 35's now and she gets around just fine.

I've used tuners with custom programs on my diesel vehicles in the past. I haven't used them on gasoline engines.

But in general tuners can significantly improve fuel mileage by heavily leaning the mixture at partial throttle. But my understanding is that the OEM doesn't do this because leaning the mixture raises the exhaust temps which will change the NOx output (violating EPA regs?). A side effect of changing the NOx output is possible damage to the catalytic converter over time because typical 3-way cats expect a particular ratio of the gases they are converting to maintain a balance of the reactants in the converter.

On gas engines some of these tuners work just the opposite. The ignition timing on gas engines is often retarded to make the engine run hotter and thus reduce emissions. So increasing the ignition timing frees up some power and makes for better throttle response. At least that is the way it works for some of these units.

Same here, running 33s

I get about 1 mpg better gas mileage running my Superchips in 87 tune. Tested it several times. Better throttle response also. Don't regret getting mine.

Your gear ratio on the FlashCal needs to match your actual ratio. On the Flashpaq, you can use off road tpms mode to effectively turn off the TPMS. I don't know if the FlashCal does that, plus I have a 2010.

Lucky for those getting 20 + mpg..I would assume your rigs are stock.I get 14 mpg with my current setup.

I think they are worth the money specially for people with modded jeeps.

Not stock here. 5.5" long arm lift, 5.13 gears, 37" tires. I wouldn't waste the money on a stock Jeep as it wouldn't make any sense.

I did worded it wrong...but I have 4" lift on 37s with 5.13 gears and at best only get 15..nowhere near what you are getting. Would like to know how you get 20 + for even when I have it set on "mileage xs", tire measurements set properly, gear ratio set to 5.13 still cant touch 16. I drive conservative so its not that, did you do any engine mods? Which by the way what I meant when I asked if its stock.

I got the tuner when I regeared and 37s so I can recalibrate my speedo and program the right gears. I really don't care about gas mileage but would welcome it if I can get it. Had the tuner since 09.

 

[d_rehmann]

Would a tuner be useful if you wanted to run bigger tires while trying to avoid a regear?

 

[lexington01]

This would be like using hand sanitizer when you really need a shower. There might be a very slight benefit but it's only a stopgap for what you should be doing.

Can you tell I have kids?

 

[Cdwright]

Would you get superchips or the diablo tuner?

 

[trailless]

Would a tuner be useful if you wanted to run bigger tires while trying to avoid a regear?

Since you have an auto, yes. You can recalibrate your speedometer and, in turn, it will adjust your shift points.

 

[DiscDog]

The PCM/ECU (ie jeep computer) is programmed from the factory for the gears and tires that ship on the vehicle. If you change either of these items and dont account for it you affect many aspects of vehicle performance because the computer is looking at engine RPM, vehicle speed, air intake etc etc and a lot of the factors are based on the gears/wheels it thinks its spinning.

When you alter that the ECU is no longer accurately displaying speed, shifting properly (auto only obviously) and it may actually effect traction control etc.

A tuner, if for no other reason that altering gear ration and tire size is almost essential. Just get the AEV procal or flashcal if your not interested in extra tunes.

 

[teach95]

Skullylady and JT_Ripper are correct. I have a 2011 JK Sport 24 S package, 3,8l engine, 17 wheels and BF Goodrich Mud Terrain tires (rubicon). No lift.

I just installed the Superchip Flashpaq 3872, set to 87 octane, and wow--big difference in acceleration. I live in Colorado so you have the added affect of altitude, and this thing actually can move now. Now, don't expect drastic, head over heels change in performance, but it is very noticeable--enough to the point that I am no longer considering the new engine and, I was actually running with a Toyota Sequoria on the interstate as they tried to pass me--not this time! It's effortless to stay at 80mph now and passing is no longer an issue as acceleration is improved.

So, for 300 bucks, very hard to beat.

MPG has not dropped, but if it does, I'll try the MPG tune.

 

[Charlie14]

Would you get superchips or the diablo tuner?

I am wondering the same thing. Wouldn't mind some extra acceleration and better gas mileage especially after lift and larger tires.

 

[teach95]

I would go with Superchips. They've been doing this a while, and all the other posts about diabolo are not good.

Anyone have issues with running a flashpaq and having the dealer deny a service claim?

 

[teach95]

thy can't deny a service claim regardless of what you do aftermarket. See FAQ on the super chips website:


Does installing a Superchips tuner void my factory warranty?

No. It is illegal for a dealership to void your warranty based solely on the fact that you have installed an aftermarket product. The dealership must prove in a court of law that an aftermarket product has decisively caused the damage to the vehicle under warranty. As a precaution, always remove the tuning before going to a dealer for service. For information regarding denial of warranty coverage, review the Magnuson-Moss warranty act.
