Mini Maxx V2 is easy to install!

Installing the Mini Maxx V2 is a straightforward process that can be completed in just 30 minutes. The unit comes with detailed instructions, and there are no specialty tools required. 

ALWAYS ensure that your truck is connected to a battery charger before flashing your PCM. DO NOT proceed if you don't have a battery charger.

ALWAYS install the tuner before modifying the hard parts, you are more likely to run into an issue with the tuner and may not be able to proceed.

*2018+ RAMs require a bypass cable (#42215), you must use this bypass cable or you can corrupt your PCM.  This bypass cable comes with a replacement OBD Box and USB cable.  Replace the OBD box that comes with the Mini Maxx with this bypass version with the red stripe.  Connect one end of the USB cable into the port on the side of the OBD box and the other side to the green connector behind the dash into the 5th port down on the connector closest to the driver seat.

I'm very impressed with the Mini Maxx V2. It has allowed me to delete my DPF system which was causing me a lot of problems. The Mini Maxx V2 is very easy to use and it has a lot of great features.
