The JLs and Gladiators have a couple of buses actually. There's the main bus which is called CAN C, another is the Internal High Speed bus. In addition, some modules do use Private buses to talk each other direct, such as the shifter for example. It talks to the trans through the main bus and a...

Not normal, is the fan running on high constantly? There should be fusible link in the power wire to help prevent this too. The SS fan uses the same connector and on the pentastar Jeeps we actually reuse the connector we just repin the signal wire to the GM side. I havent seen this happen on any...

Yea first rule of owning a Jeep, get either $0 deductible for comprehensive or if you have something like progressive, then whatever deductible for comp but $0 for glass.

Now lets see those RPMs 🤣

Time goes so fast, crazy its already that time again. Thank you guys for hosting another New Years run, last year was alot of fun! My name is Kalan and I will be driving our 2007 JKU. Not sure if Crystal and the baby will be up for it but just in case there they are too.

Check all powers, grounds, connections and make sure they are tight, next see if you can get your hands on a good scanner like an Autel or Snap-on. Really anything that will read all the modules in the body of the jeep not just the ECM. Then do a full network scan and see what codes are being...

Try doing an ABS bleed. You need a scanner but essentially the ABS module will pulsate and purge the remaining air out of the lines.

02s are fairly cheap go with Mopar or NTK. Ive seen issues with some of the bosch ones on Jeeps. Jeep PCMs arent uncommon to go out but before changing it I would get the new quality 02s in and check your voltages, grounds, and heaters first.

The JK pentastar fan programming is backwards. Its a 10 Hertz, and the tables are opposite of what you think. For example, lets say your looking at the coolant tables and the lowest temp it shows is 196° the fan would be running at 90%, 200° fan would be 85% etc. The higher you put the number...

RCP ( Racing power company). Is the company and we use the 3x10. Get the biggest one you can fit. Since these are metal, not only do they absord the heat from the engine bay, they are also exposed to the atmosphere. Meaning you will need to check it often as the coolant will evaporate rather...

You can get a cheap one through amazon and they work the welds just dont look great. We get ours out of Cali, I just cant recall the name of the warehouse at the moment , they do cost more but we do not have issues with them and the welds are very clean.

How many miles do you have since you cleared codes or disconnecting the battery? The 02s usually need a few cold starts and need to be driven like 20 minuets each time, the cat wont set till the 02 sets. If there is a problem it will throw a code after the monitor completes

Theres nothing to get around, its perfectly legal to run other manufactures powertrains in different vehicles, you do need to run the full powertrain though, so engine and transmission must match. Running a hybrid, like a GM engine but Mopar transmission is not legal.

Yes, one our goals this year is to get the website going with more info, most guys get the info from our YT channel WranglerJKLS. Stop by anytime were there 8-5 🙂

All JKs have 241Js, so youre good 🙂
