Reviews for Superchips 3571-JL Flashcal Programmer for 18-24 Jeep Wrangler JL
Installing the gateway by-pass module is easy once you figure out how to reach and unplug the two wiring harnesses. Other than that the programmer is easy to use and does what it says,
Simple to use
una muy buena opcion para configurar mis nuevos neumaticos de 35 " .y tiene muchas otras buenas opciones de configuracion .....
Works great
worked perfectly for my JT.
I installed this last night to make the adjustment to my tire size. After reading some reviews and watching a few install videos I was a little weary about getting the bypass module installed. It was a bit awkward to reach but I was able to get it done and the tire size modified in about five minutes. Very simple interface, with step by step instructions.
Very easy to install and use . Instantly once you change the dimensions of the tires you notice how the vehicle stops to run rough. I also noticed how my fuel improved dramatically to over 4mpg! I was also having TPMS issues so I decided to turn it off. I would highly recommend it. Only issue is that it is expensive but what isn’t these days.
As advertised. Would be nice to control the rear camera for larger tires making the collision alert go off in reverse.
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.
