    F5 Flashpaq for Jeep® is rated 4.4 out of 5 by 89.
    Rated 4 out of 5 by from Big Difference I installed a throttle body spacer and cold air intake but only got a slight improvement in throttle response and some noise. It wasn’t until I uploaded the 91 octane program from flashpaq that I saw significant results. My only complaint is that it didn’t offer much other than the 91 octane setting. I was hoping it would also have the 98 octane setting and the extreme setting available (I think that’s what it was called) but it was worth the investment. My 2000 Jeep is faster than when I first purchased it.

    Rated 5 out of 5 by from Great For Towing I bought this a few weeks ago after for my 2012 Jeep Wrangler in hopes of improving towing of my 17' travel trailer and improving shift performance. I've only tried the regular performance setting and 93 octane towing settings so far and I've noticed the biggest difference while towing - I have way more towing power! The regular performance setting has also improved the throttle responsive and brought back the power as I'm now running 33" tires. I love the option of being able to scan for codes especially when travelling and I'm unable to stop for a scan at the dealer. A lot of the other features are already available for changing through my Jeep but there are a few other neat features which I haven't yet felt the need to adjust.

    Rated 5 out of 5 by from 2014 Jeep Wrangler Sport A few months back I bought bigger tires for my Jeep and I had no idea how much they would drag the Jeep down I finally broke down and bought the Superchip and am I ever glad that I did performances let's say amazing and it shifts gears like it used to which is much better than what it was doing I would recommend this Superchip to anyone owning a Jeep at the moment I'm getting 2 miles a gallon more per hour then I was I would say it is well worth every penny

    Rated 5 out of 5 by from 1998 Jeep Grand Cherokee 5.9 limited I have had the super ships programmer on my 5.9 and it definitely woke up the Jeep and seemed to have “optimized” the shift points like Superchips states and I can honestly say it shifts better and more crisp. There was a noticeable difference in power with the performance tune but the mileage tune was where I noticed the most positive improvement! Great and easy to use ! Also no more speed limiter ! Great product!

    Rated 2 out of 5 by from poorly marketed imo 91 tune is slightly noticeable To my understanding I was supposed to have a 93 tune. Under the manual it says this varies. Under another part is says it will fully support basic bolt ons basically. Than on another part says it may not support basic bolt ons. What gives... than not only do I not have a 93 octane tune there is 0 improvement in any shifting AT ALL. Performance feels a tad better maybe but honestly for 400 bucks with all the advertised features than hidden in the manual a ton of discrepancys. No option for a custom tune? Is this a joke? My ancient x3 will be the replacement if I have to return this 3874 cause atleast even though it's for fords i can have any make or model tuned on it /rant over . Firstly I wanna ask. WHY is there no 93? Around here we dont get 91. Its 87 89 or 93 unless I drive 30 sum Miles just to get 91 for 20 cents cheaper. I didnt update it but I have now and will check it out again. However what are these updates even for? If we cant load custom tunes and the tunes are now only focused on the wranglers it seems... what good is it to me? Any gain? Any new feature I wont have? Any difference in tuning itself? I dont understand the updates if make and models are set in stone per device # and already loaded with tunes? Im okay with the engine or maybe it's just my imagination. Everything else though theres nothing. Just tire calibration and an idle adjustment seriously after all the marketed features? And the flash cal to flash paq upgrades. THE SAME DEVICE I mean what gives here this is garbage and I'm pretty upset I spent almost 400$ on a device that will only do a generic tune and MIGHT except a bolt on or 2 with not 1 feature I couldnt correct myself. I'm trying to make it feel like it was worth it but I think for the features obtained... or really just 1 feature that a 100$ custom tune wouldve gave me better performance and the same features... on a way way way way older device. Tell me I did something wrong here otherwise it's going back to the parts store it came from. Tryed update no difference. 04 grand cherokee laredo 4x4 4.7l v8 vin n non ho.

    Rated 4 out of 5 by from Good Product Just got this yesterday. Done an update online before using as I have read that you really need to do that first. Plugged it in and picked the mods that I wanted or needed. First I changed the tire size to the oversize tires on my jeep by measuring from the ground to the top of the tire and that set the speedometer and odometer, it is now dead on the money. This improved shifting on the automatic transmission considerable also. Next after making sure I had a full tank of 93 octane fuel in the tank I set it to the 93 octane performance setting. Went on a 400+ mile trip today that consisted of highway and dirt roads as well as some idle speed driving on a wildlife refuge. The engine is no longer sluggish and I don't have to press the gas peddle near as much to make it up hills on the highway and my gas millage has Improved about 4 to 5 mpg. It ran smooth and peppy with no overheating or pinging. Got on it pretty hard one time on a sandy dirt road and I'm happy to say that I am quite pleased with the product. The only thing I wish it would do is let you choose the air pressure on the TPMS instead of just on or off. Haven't tried the crawl setting yet but will when the going gets rough. Haven't tried the fuel save with 87 octane either but am getting better millage anyway with better performance. That's about it for now. I'm happy so far.

    Rated 5 out of 5 by from Must buy for lifted modified Jeeps I love this product. It leveled out my throttle response, helped a little with MPG, and has given me more HP. It also corrected my Speedo that was about 8-9 MPH off at freeway speeds. Great Product.

    Rated 1 out of 5 by from 2012 Jeep Wrangler is dead Flashpaq worked fine for my 2012 Jeep JK for about 1yr. Recently updated the flashpaq & installed tune 87 on Nov 14, 2018, & immediately afterwards my Jeep won't start. I can hear clicking behind radio, glovebox, and fuse box. It is now sitting in the gym parking lot dead. Afraid I am gonna have to spend money for a tow truck and even more money at the delearship. Was supoosed to have 4.88’s installed this coming Saturday but that is not going to happen. Feel like I want to barf

    Rated 1 out of 5 by from Did not help my Jeep at all. I have a 2004 Jeep Wrangler Unlimited with 33" tires and 456 gears. It has been poor performing when going up hills in overdrive. The website states that I can set my tire size (true) and gear ratio (false), which will help optimize performance. I've tried each of the options available and I see zero performance improvement.

    Rated 4 out of 5 by from Good amount of options I purchased this almost a year ago I have taken the time to use it and figure out what it can and can't do I was a little let down to know in order to use my lockers in high range that the programmer had to be on and plugged in. I found that putting the drive by wire throttle control all the way to its most touchyiest setting well it's extreamly touchy. I love the crawl tune but it does take some time to reprogram every time I want to use it. But no longer then the rest of the guys airing down and to program it back after crawling wile the guys air it up. It comes with a ton of features and things you can adjust and turn on and off like that pesky tpms light. Over all I would purchase this again now looking to get one for the wife's jeep

    Rated 3 out of 5 by from Great item I bought the flashpaq about a month ago and I’m happy with it so far.. easy to use and understand.. only thing that upset me was at the fact that the website said they were giving grab handles with the purchase and when it arrived I did not receive them when I called they said the promotion ended in July, which is understandable but why would they have it posted in their website still in November.

    Rated 5 out of 5 by from Flashpaq for Jeep Wrangler I have been using the programmer for my 2009 Jeep Wrangler for the last 6 months. I have used the 87 performance tune and the economy tune. The performance differeceived with the 87 tune is noticable. Improved pedal response and quicker transmission shift points have made my JK get up and move. Also used the programmer to change lighting settings and TPS for off road use. I would recommend this tuner for every JK owner. I also have installed a cold air intake and cat back exhaust system. The tuner adds more to these performance upgrades.

    Rated 5 out of 5 by from Awesome Product I bought this for my JK 3.8L. It is lifted with 35" wheels on it. The power was sluggish after the lift and wheels, and my speedo was off. I did a triple shot on it and got the throttle body spacer, CAI, and the tuner. After installing everything, tuning the Jeep, and calibrating the rest of the system, my Jeep runs awesome now. Great top end on the highway, nice torque on the low side, and MPH saw great improvement on top of the additional power. Love it!!

    Rated 5 out of 5 by from Works great! Getting 18mpg with 35" tires and it has a little extra pep. It's worth the money to step up to the flashpaq IMO. No complaints. The only improvement I would ask for is a better user manual. There are a lot of features you can adjust so it would be nice to have a short description of them in the user manual.
    Date published: 2017-08-15
    Rated 5 out of 5 by from Easy to Use This is exactly what is described! If you are looking to make your Jeep into Hot Rod then this won't work, but neither will the 6 cyl. engine that is in it. If you are looking to optimize the performance of your factory motor then this is the programmer for you. I added a cold air intake and a high flow exhaust to my Jeep before ordering this programmer because I wanted to see how much of a difference each component made on their own. The cold air intake and exhaust made everything smoother, but the Flashpaq took my Jeep to a whole different level. I got noticeable power gains and through (3) tanks of fuel I have gained approximately 2.6 mpg. The biggest difference I notice is when I downshift to pass my Jeep actually has the power to quickly get around the other cars.

    Rated 4 out of 5 by from Good product Have been using for about a month in 2011 Wrangler JK. Easy to use interface. Pleased with 87 octane tune. Performance increase is acceptable (it's a Jeep). Haven't tried the higher octane tunes or crawl tune. Like quick option customization, but only 4 stars because it won't customize to run fog lights with high beams as claimed. Would recommend for those looking for a little increase in performance with ability to make tire size adjustments and a few other tweaks.

    Rated 5 out of 5 by from A required Mod to any JK build I've owned and used this product for about 9 months now. I run 38's with 5.13s in Colorado and use my JKU both as a weekend warrior and primary daily driver. The 3.6 is a gutless wonder but after using the flashpaq it makes driving the vehicle much better I use the 87 oct program and see a better power band and far better performance over stock. The Crawl mode seems to limit throttle response and smooth out your RPMs which is great for Crawling because I have way more control over my throttle and do a lot less bouncing and spinning. I tried the crawl mode last weekend while doing some snow bashing in the Rocky Mountains and it definitely helped keep me up on top of the snow and that control of the torque kept me driving through with no problems even as the trail leader. In 9 mo's I've not tried all the programs yet but from what I have tried I can tell you that this product is about # 1 on the list of things to buy when starting a JK build.
    Date published: 2017-06-06
    Rated 5 out of 5 by from Great way to the a build together I've been running this in my 2008 JK since July and I'm very happy with it. From small things like shutting off my DRLs and correcting my speedometer for bigger tires, to bigger features, like adjusting my auto transmission's shift points and bumping my idle up for winching, its been an easy process. I'm running a raised cold air intake, headers and exhaust and with the 91 and 93 octane tunes, the Jeep has responded very well to them.

    Rated 5 out of 5 by from Amazing product I have waited a year to write a review on this product because I really wanted to get to know this product. After this year I can safely say that this product has changed everything on my 2011 Jeep wrangler 3.8L. The 3.8 has always been very sluggish especially running teraflex 44HD axles with 37s. LOTS OF WEIGHT! It has improved my gas mileage, improved power output, and made the Jeep fun to drive again. I would definitely recommend this.

    Rated 5 out of 5 by from Never lets me down I bought my first one nearly 5 years ago. It was stolen last year, and I had to run my Jeep on the mileage tune for 6 months until I could save enough for a new one. I bought my second one, and I never leave home without it. From reading DTC's to switching tunes, Ive never been let down my my Flashpaq!!!!

    Rated 4 out of 5 by from Works great Bought this for my 2007 Wrangler and 2006 Cherokee. Works on both, but gets VIN locked to one Jeep, upon use; I can't use it for both. In hindsight I should have bought the Diablo tuner as they only charge an extra $99 to program an additional vehicle, rather than requiring you buy another unit. All in all it's quite nice. Easy menu system, loads of options. Since I have one already, I'll buy another for my other Jeep.

    Rated 4 out of 5 by from Most features work great Bought this a month or so ago primarily for speedo healing but also to try the fuel maps and make some other adjustments. This was needed due to moving to 5:13 gears and 35 inch tires. Started off with 92 octane custom tune wherein you set the attributes you want, select the tune. It saves the existing tune and it loads the new tune with the new tweaks all at once. On the first two attempts it crashed while it was trying to clear the codes. This may have been due to the TPMS sensors not registering the tires so it could never clear the code. It finally took however. Don't know why it worked the third time but it has been working every time since. Works great for gear, tire size, TPMS disable and power off timeout. Have yet to get it to work for increasing RPM. Wanted to move to 800 from 700 at idle and it acts like it works while plugged in as it does increase the RPM. It always resets back to 700 however. On the tune, I have a manual transmission. It does seem like there is a bit more power but it is hard to tell. I've always had to ring its neck (drive it hard to higher RPM's before shifting) to get it to get out of its own way. Nothing has really changed in that regard and with the gear and tire size change I've managed to get the mileage down to 13.8. None of the tunes seem to increase MPG. With an auto transmission I hear the difference is greater due to the changing shift points. In general it is a necessary tool in the Jeep toolbox if you are going to tinker with your Jeep. And really, what other reason is there for owning a Jeep beyond its tinker toy value.

    Rated 3 out of 5 by from Doesn't do all that I thought it could. I wish I knew ahead of time what this product could and couldn't do for my Jeep before I bought it. I can't even use it as a scanner and the choices of modifications are very limited. I can't recommend this to a friend not knowing what features work or don't work with a particular car, truck or SUV that my friend owns. Not worth the price I paid and now I see there is a $50 rebate which makes me more upset.

    Rated 5 out of 5 by from Noticeable performance improvement The programmer arrived in less than a week. Connection was easy and the menu easy to follow. Throttle response initially too touchy but able to dial it to my preference without problem. Added a Flowmasters exhaust and a cold air intake. I’d at minimum hp gains calculated, my 2012 Jeep now pushes 320hp and is very much improved! The Superchips programmer is worth every penny, you won’t be disappointed.
    Date published: 2020-04-18
    Rated 5 out of 5 by from So easy to use!!! I purchased this after changing out my stock tires to 33s but it ultimately saved me a trip to the mechanic after getting a check engine light on the dash. After plugging in the FlashCal, it gave me a code of a faulty oil pressure sensor, which I was able to repair. The FlashCal is so easy to use and I’ve noticed greater gas mileage and smoother shifting. Such a great product.

    Rated 4 out of 5 by from Great features “almost!” Every function I have used or experimented with have worked as operated. My JK Rubicon is an automatic and the only function i wish it had that is doesn’t is a means to firm up the shifts a bit. The 93 octane tune helped get my 35’s up these mountain highways in North Georgia without nearly as much downshifting before the tune. I am very pleased overall with this tuner.

    Our Flashpaq will allow speedo adjustment for larger tires on your Grand Cherokee. As for power gains, in the 4.7L we've seen as much as 21hp/20tq at peak with improved throttle response and better drivability.

    I have two jeeps. can this unit be used for both? I know they will both jk and wk2. I just want to know if this unit has to be plugged in 24/7. or can it be disconnected. Does it have to be plugged in to work or can you set your options then unplug? 

    Asked by: Dani123
    The device does not have to be plugged in all the time, you can use it to adjust your options and flash your tune then remove it. However, if the device is used to change any functions on the vehicle, it will be vin locked to that vehicle. They will only work on one VIN at a time, so if you have two Jeeps, you'll need one for each .
