NEW SUPERСHIPS FLASHPAQ F5 HANDHELD,COMPATIBLE WITH 1999-2014 JEEР WRANGLER

Worked wonders for my JKU, recalibrated and running a 93 octane performance tune. Does very good, absolutely worked wonders. 10 to 1 difference!

I’ve had this FlashPaq4 Tumer for my 2005 JGC HEMI 5.7L, for almost 2 years now.I feel like it is worth every penny. With Multiple engine tunes, options of monitoring live data while you drive or engine running. You can do and monitor so much!! From live miles per hour, to adjusting exact tire size to 1/4” calibration !! Precise RPM monitoring, engine temperature, ambient air, oxygen sensors , catalyst temperatures, and so much more! You can update the power train module to know the exact tire size and gear ratio! For perfect speed calibration!MOST IMPORTANTLY, you can turn off your Engine MDS cylinder deactivation system, which is infamous to cause premature engine wear! most important benefit. You can turn off your TPMS system etc. It is just such a great tool. I’ve towed 7200 Lbs on the Tow tune with noticeable differences in shifting and power! The high-performance tune, Really turns it into a beast and feels like 20/30 horse added! , especially if you have other add-ons to complement it like myself. Exhaust intake ignition cooling etcWell worth it!

The Flashpac worked great on my Jeep JK. The problem was with the seller. They claimed it was a new Flashpaq and when I got it it was VIN locked. Luckily the guys at Superchips/ Holley hooked me up at no additional cost.My Jeep runs great and the Flaskpaq is easy to use and straightforward. I would definitely buy again just not on Amazon.

I have a jeep Rubicon 2008 with 84,000 miles. Mint condition. No engine lights on. Garage kept. Was getting 17-20 mpg. When I installed the flash pack to 87 to increase MPG I started getting 11 MPG. I then tried just the 87 tune. 9-11 MPG. So far it’s a very poor product. I’ll keep you informed as I try different times

This thing is so simple to use, I change the tuning settings regularly for my different driving purposes. Performance, towing, and crawling are examples of different engine tunes available. Speedometer is dead on now after programming in the actual tire size. Glad I bought it.

Worked as advertised. I was able to calibrate for the 37” tires and 5:13 gears in my 2008 jk. Before that the engine would really struggle to maintain even low highway speeds. With the 91 octane tune It’s not a problem now, I’m no longer the slowest vehicle on the freeway!It also GREATLY improved the throttle lag. I haven’t been going easy on it and after a few tanks through it the computer says about a 2 mpg increase.While it does greatly improve drivability for modified jk’s, dont expect it to be a sports car. We’re driving around underpowered boxes afterall.P.s. the option to get rid of the god awful honk with locking was worth it alone.

Just bought an 02 jeep grand Cherokee with 4.7HO motor. I was surprised at the stock mpg, a short, flat highway run at 65mph netted a solid 24mpg. Many have reported much lower. In town things go south to around 16 to 17 mpg or worse for some. The power is kinda diesel like, strong on the bottom then anemic around 3000rpm. Not terrible but a little rough around the edges. I just happened to have a superchips f5 laying around and tonight decided to install. First I tried the mileage xs tune. At first I really liked it, smoothed out the bottom end and pulled better until about that 3000rpm mark, then got anemic. The instant mpg showed quicker af changes in the ecu. The mpg would go up quicker than stock and had no problem going up to 50 plus mpg when rolling up to a stop light or turn. Stock in comparison was very sluggish and might hit 25 under the same circumstances. Next I installed the 87 octane tune. The bottom end felt the same as the xs tune which was good and pulled noticeably better after 3000rpm. The instant mpg read out similar to the xs tune which was what I hoped for. Not enough time to verify any mpg increase, will update later. The power is smoother and stronger than the stock tunewhich is definitely a plus.21 Apr 24 update: A few updates from superchips really ruined the mileage xs tune. Someone took timing out and kept the torque converter from locking up. Mpg dived to 15mpg. Someone doesn't know what they are doing. I went back to the stock tune with added timing to get back into mid 16s mpg. I thought I would try the tow tune and, wow, glad I did. My jeep now drives much better. The torque converter locks up early and stays locked up. Now U actually get really good acceleration instead of the vacuum cleaner affect. Low end is very strong and will rev out decent. The best part is my mpg is back up. I recently did a long distance road trip pulling a small trailer, about 2000lbs. The first half of the trip was very hilly. I thought 14mpg would be great under this condition. The first fill up netted 16.5 mpg. Every fill up averaged around 16mpg for the duration of the trip at 60-65mph. The tow tune drives alot better than the mileage xs tune and the stock tune but trumps both in economy. My first tank unloaded, driving around town so far is 17.5mpg and slowly going up. All listed ratings are hand calculated. I will say that my evic is right on now. It was off about 3/4 to 1.5 mpg. I may have accidentally found a way to recalculate it. Alot of people know how to reset the gauges, I've done it quite a few times with negative results to correct the evic reading, until one day. After I filled up at the gas station, I decided to reset the gauges before leaving. Doing it this way fixed my evic error, and now it's right on.
