I love how all the contrarians had to come out of the woodwork no no you absolutely should spend $1,000 on your first mod so you can put air in your tires like really...

Too many people on the internet have no grasp of reality.

I mean when you spend a shit load of time off road and actually do air down being able to do it in 1/4 the time its nice. Also helps with never having to find air anywhere for any reason anymore. My other first mods were protection for underneath the Jeep. Contrary to popular opinion I didnt go lift and 37s, or an angry grille and sparkly tinker bell tire cover.

A little education here. California is the 4th largest beef producer in the USA. Plus California produces 20% of the US milk with well over a million barn cows. Thats truly is BS!

Many recommended JSCAN.

Would you provide me some insight to whats the best OBD adapter?

Additional question; for a 2021 Rubi 4DR 3.7 do I need a harness to bypass the security gateway?

Thanks!

Hi Larry,
You'll need the harness to bypass the security gateway, and I recommend some extension cables since it's kind of a PITA to get in there every time you need to connect the Bluetooth adapter to make changes. I just went through this because I put 35's on my JL Sport and needed to correct the speedo, and my son added paddle shifters to his JLUR so we needed to activate them.

I downloaded Jscan and bought 3 vehicle licenses since we have 3 JLs. I believe a single vehicle is $20.

I bought the VLinker MC+ Bluetooth adapter for ~$50 - https://www.amazon.com/dp/B0C2GT4KR3

The SGW Bypass cable for ~$15 - https://www.amazon.com/dp/B08ZL4LRVK

And SGW Extension cables for ~$15 - https://www.amazon.com/dp/B0D7Z8LG16

You are right, the cost at the dealership is crazy, considering you can DIY all-in for around $100 and have the ability to scan for codes and make many more changes in the future for no extra cash outlay.

Hope this helps!

I use a OBD Link MX+. You also need the Chrysler 12+8 cables

I second the recommendation to get the extension cables along with the bypass cable. Either Amazon or zAutomotive. I think zAutomotive had a video for doing the installation; it’s a bit of a pain to get to the connectors.

california has a special winter blend air the gas stations all switch too. It costs about a quarter more, but its better for the environment. Allegedly…

You had me there for a minute... Not because I'm a moron (well...), but because that's just the kind of stupid shit that California is known for.

Need some folks with experience with JSCAN TPMS to answer this if you would please?

How low of a PSI can I set my TPMS with a JSCAN? I understand per the JSCAN web page I can just turn it off. However, is there a low setting if its left active? I see some OBD tuners that will just go to 35PSI is JSCAN the same?

Also if its active what is the PSI Alarm range if its reset? IE: I reset it at 32PSI vs the factory 37PSI. Will the alarm go off similar to the factory settings or at around 5PSI below the setting?

Thanks

I can’t remember how low you can set it. I keep mine at 28, unless I’m airing down then I change it to a lower setting.

25 is the minimum setting and that's hard coded into the computer of the Jeep.

Edited to add @autotragic types faster than me
From what I have read the Jeeps computer will only recognize the settings down to 25 psi

There is a difference between ignorance and not giving a fuck. I'm the latter not the former.

And there is also a difference between offering useful advice and expressing your personal opinion. Opinions are like hemorrhoids, everyone has one sooner or later, and they always stink and irritate.

Milk trivia - milk and milk products produced west of the Rockies hardly ever makes it east of the Rockies. A large part of the liquid milk produced out west either stays out west or is converted into non-liquid milk products (primarily powdered milk products) and shipped overseas…China, Philippines, etc. Plenty of Milk on both sides of the Rockies to make if viable to ship over the mountains.
