Reviews for Superchips 3874 Flashpaq F5 Programmer for 98-14 Jeep Vehicles
works great
works great, lot of options, and the tune with throttle adjustment helps quite abit when it comes to butt dyno.
A little pricey, but greatly improves shift points and performance in my 2012 JK.
Worked great on my 2012.
The product is easy to use. Great for trouble shooting DTC's. I'm not a fan of most of the custom tunes however. I've tried the performance tunes and the mileage tunes. It only added about 1 mpg in additional savings and I didn't like the shift points it set so I have since set it back to the stock tune and just use it to change settings and diagnose check engine lights.
Great product, noticeable bump in power and worked great to recalibrate my speedometer for bigger tires.
I installed this on my 2008 JKU that also has a CAI, axle back exhaust, and Jet Performance Throttle Body Spacer. My Jeep was a little sluggish after adding 35" tires and I was trying to just get a little bit more pep out of it. The calibration functions of this device are great. My speedo is accurate again. Of the performance tunes I have only used the 87 Octane tune so far. My experience has been that there is a little more responsiveness with the addition of the tune. It seems to be making a bigger impact at higher RPM but I do think that I feel some improvement at around 2k RPM and a slightly more improvement at higher RPM.
not impressed with directions for updating, haven't installed in jk yet but when I do I'll update
Did not make a noticeable difference in power on an 08 v6. I was disappointed to find out I had to buy another "subscription" for $100 to use it when I traded Jeeps.
I gave this 2 star only because of the Quick Tune options. The issues I had with my JK is that, under the fuel economy tune, my mileage decreased 2 mpg. Not increased, but decreased. And the other issue is regardless of the tune, my cruise control malfunctioned. When and if it would turn on, is would shut off after a few seconds. I tried different tune , reprogramming, etc. Still the cruse malfunctioned. Will not purchase again.
