OBD JScan 17+

The app works great. I was able to change tire size, TPMS, gear ratio, and a few other little things on my 2008 JKU in just a few minutes. Very easy to use, and a super buy for the money. I am using the Vgate iCar2 WiFi obd adapter. When I first hooked it up I could not get my Jeep to accept changes. I messaged the developer and he responded in 10 minutes. They were working on an update for that particular adapter, and he said it should be fixed in 48 hours. An update with the fix was available in less than 12. The only thing that could possibly be considered a “con” is that if you turn off the Jeep or if your phone goes to sleep, and you lose connection you have to close out the app and restart it. I simply set my display time-out to 5 minutes while I was working on it. I cannot recommend this app highly enough!!!

I don’t know if the developer will read this but thank you for this app. I was in a world of pain after my speedo was 5mph off after using a calibration tool. I then spent a couple of hours fiddling around with a well known app to fix the issue but it left me with a miscalibrated speedo and a bunch of ABS trouble codes which I couldn’t clear because the ABS initialization function didn’t work.

I bought this app on a whim after hearing about it on the forums and it just worked. No errors and I verified that my GPS is accurate. I was about to give up and take the day off to go in to the dealer.

Minor feedback to the developer - there is a DJ Ram 2500 link which worked for me for my 3500 but the 2022 Ram 3500 isn’t listed directly.

If you own a Jeep (I’ll assume dodge or Chrysler as well), it’s worthwhile spending money on this App. Not often do things do what is advertised, however JScan proves otherwise. I feel like it under promised and over delivered. I researched enough to understand how the different parts within the vehicle operate (interactions with similar and different hardware/software); built the confidence to clear out all previously programmed keys and reprogrammed new ones. Now, I no longer worry about someone finding my old/lost keys. As a bonus I was able to turn off the annoying TPMS warning since I haven’t had my original wheels and tires for over four years.
