Superchips Flashcal F5 Programmer Reviews
Just a word on unplugging the 2 plugs from the gateway module. As noted by others, it's a bitch, but here's a hint about how I managed to disconnect (after 45 minutes of futility). I took a length of twine and looped it around each wire separately and firmly pulled it with my left hand (you cannot get both hands up at the gateway module at the same time) while I pushed in with the tab on each plug with my right index finger. It requires a moderate bit of a tug, but it works. The closer you get the twine to the plug the better power you get (pretty basic physics). Also, use a long enough piece of twine to allow your left arm/hand to rest near the floor of the Jeep, it's much more comfortable. I also removed the trim from under the steering wheel to get more real estate to work with.
This is extremely easy to use. The other review is correct that getting the two cords unplugged from the OBD2 port are challenging, but that has nothing to do with the Flashcal. I’ only used it to reprogram my tire size initially, but it did have options for the auto/off and some others options I didn’t expect. It’s nice to be able to download the performance package upgrades (if you pay for them) and have them all on the same tuner.
If you are going with larger tires on your JL, factor in the $249 for the cost of this programmer i addition to the new tires and rims. I put Toyo OpenCountry AT2 35x12.50x17 tires (no lift) on my '18 JL Rubicon 2 days after I purchased it. The computer was forever searching for shift points. My gas mileage dropped substantially (20ish to 13ish mpg). After using the Superchips Flashcal F5 Programmer to program the tire size (34.5), the computer now shifts smoothly and on my first tank, I am back at about 19mpg. A few things are left out of the owner's manual and the SuperChips YouTube video. You do not "easily" unplug the two wires and replug them into the Jumper Module. (They stay permanently plugged into the Jumper Module) Getting your hand in between and above the OBD2 port to initially unplug the two wires is quite difficult. There is no room for a 2nd hand and no room for a screw driver. I could press down on the release clip (at the back of each plug) but not pull each out at the same time. I ended up going to my local garage and one of the mechanics (complaining and then nursing the cut he got from the under dash) was able to unplug them. I plugged the programmer into the OBD2 port. I have a push button start, so pressed it TWICE to achieve the ignition ON without starting the engine. It took me less than 2 minutes to adjust tire size and turn off the seat belt notification. There are a hundred more adjustments that can be made using the programmer. Once finished, you unplug the programmer. Additionally, I have to mention and give a big thumbs up to SuperChips for being able to update the programmer on a Mac! Programmer updates can be done on a Mac or PC! Highly recommended and a necessity if you are going with larger tires.
