Will it install easily on a 2012 Rubicon, and will I be able to upload the tuning file easily?
Yes, the Magnuson TVS1900 Supercharger Kit is widely considered one of the easiest and most reliable forced induction upgrades for the 2012 Jeep Wrangler JK.
Because your Jeep is a 2012 model, you avoid many of the complexities faced by owners of newer JKs (2015–2018), such as the requirement to ship your PCM out for unlocking.
Installation on a 2012 Rubicon
The installation is a 100% bolt-on process that typically takes a capable DIYer 8 to 12 hours (a full weekend) in a home garage.
No Permanent Mods: There is no cutting, welding, or hood modification required. The system is designed to fit under the factory hood with an OEM-level fit and finish.
Rubicon Specifics: It is fully compatible with both automatic and manual transmissions. It also retains the high-mount alternator position, which is critical for Rubicon owners who plan to take advantage of their electronic lockers in deep water or mud.
Tuning and File Upload
For a 2012 Jeep, the tuning process is straightforward and does not require a PCM swap or professional shop equipment.
Handheld Device: The kit includes a handheld programmer (typically an HP Tuners RTD device).
The Process: You will use the tool to "read" your factory file, email it to Magnuson’s calibration team, and they will send back a custom tune within 24–48 hours. You then simply "write" that new file to your Jeep via the OBDII port.
Requirement: You must use 91 octane gasoline or higher once the supercharger is installed. Magnuson recommends running at least one full tank of premium fuel through the Jeep before you start the installation.
Key Performance Gains
Horsepower: Approximately +105 rwhp (reaching ~404 hp at the crank).
Torque: Approximately +84 ft-lbs (reaching ~367 ft-lbs at the crank).
Efficiency: Features an internal bypass valve that virtually eliminates parasitic drag when you aren't under boost, helping you maintain factory-like fuel economy during highway cruising.
My Recommendation:
If you want the most power with the least amount of "fiddling," the TVS1900 is the right choice. However, if you are looking for a slightly more budget-friendly option and don't need the maximum possible output, the TVS1320 is also available for the 3.6L Pentastar.

Will the programming work if I have a previously unlocked pcm from superchips?
No. The PCM would need to be returned to stock parameters. Thanks for your inquiry.

How is the oil filter access with the supercharger installed?
In the picture, the oil filter housing looks like it sits pretty close to / right under the blower pulley.
Good question. For model years 2012-13 model years you will receive a 2 piece oil filter which will help in this instance. For 14+ the location was slightly moved enough to not need a 2 piece filter. Thanks for your inquiry.

Does this Super Charger have a CARB EO number?
