Burger JB4 tuning available now

Yes, we discovered that when I'd go over to my neighbor's place on a near-weekly basis to extinguish the CEL light on his Dodge Dakota. He was chasing a fuel system error code that was eventually and correctly identified, but not before replacing a few parts that didn't themselves require replacement.

Eventually, the annual inspection sticker came due, but he didn't pass despite me using my code reader to turn off the CEL light and, presumably, clear the underlying codes. The shop advised him that the vehicle must be driven at least 50 miles, without the underlying problem(s) reoccurring, before the CEL code was automatically erased from the ECU. 'Twas the "hidden" and unresolved code hiding in that black box that was detected by the shop's emissions computer.

That Dakota was traded a few years later on, of all things, a 2020 JLU Rubicon SOT. So there you go!

My Jeep is my 2nd brand new vehicle ever. My last used vehicle was an awd 2001 Chevy Astro van. It was the LT version with all the bells and whistles including 6 independently reclining captains chairs. It was an awesome road trip vehicle and would go places you wouldn't think it could go courtesy of its auto engaging awd system. I had everything shy of the headlamps switched out to quality led lamp assemblies, and was starting to look into lift kits to fit whopping 31's. ?

Unfortunately, it fell victim to a relentless CEL. I replaced everything from spark plugs to the injection pump spider and everything in between. I ended up selling it a year later and with a nine month expired inspection sticker. Oh yeah, and that damn CEL giving me the dead pan stare all the way to the end.

Just looking for an update on this JB4. I have a 2020 2.0 E-torque that is stock and i run 91 fuel. Anyone using that combo and loving it? Hating it? What map are you using? We still getting CEL? I'm about ready to pull the trigger.

I just installed the JB4 on my new to me 2018 JL 2.0 E-torque and it seems to be a really decent power adder for the money. Can chirp 37's and hits pretty hard. Wondering which gauge setup others are running on the app? A lot of them seem to not work like IAT...
