Selling my JB4 tuner off my ‘19 JLU Rubicon 2.0L that was recently traded in. It comes with the bluetooth wireless kit as well ($140 option). It is missing the cable that goes from the JB4 unit & plugs into the OBDII port so you can track RPM, AFR, etc. I left it on the Jeep because I had it running through the firewall hole & had it sealed, so didn’t want to have to reseal that hole when I removed the cable. I never used the AFR, RPM, etc. feedback anyway, as I’d just put it on Map 2 & never looked back. The bluetooth kit still allows you to connect to yoyr phone & change the Map on the fly from your phone, you just won’t get AFR, RPM, etc. feedback unless you buy the cable from JB4, which shouldn’t cost much if you wanted it.

I’m asking $300 shipped used, as is. Worked flawlessly. Used for half a year or so without issue. New, with the bluetooth kit, it’s $669 before tax & shipping through Burger Motorsports.

Bump. Bottom Dollar on this. $300 shipped. Worked great, very noticeable low-end power boost on Map 2.
