FAQ
Common questions about compatibility, installation, emissions requirements, updates, bypass cables and error codes.
What is the difference between the V1 and V2?
The V2 is a new product released in 2022. The V1 has been discontinued.
- The V2 does not support emissions. You must remove the emissions.
- The V2 added support for later model years: 2019 Ford, 2021 RAM, 2016 Duramax.
- The V2 does not support custom tuning or overdrive transmission tuning.
- The V2 does not have all the special functions of the V1.
Part numbers: V1 is 109003, V2 is 209003.
Why didn't my tuner ask about my emissions being removed?
The V2 does not support emissions, so it does not ask whether you have them installed or not.
Do I need to remove my emissions when running the V2?
Yes. The DPF, DEF and SCR sections of the exhaust must be removed. All sensors in these pipes will need to be disconnected; it is best to leave them in the exhaust and disconnect them when removing.
Your EGR system can be left installed or removed. If you leave it installed, you need to disconnect the connectors.
Your throttle valve must be unplugged, or removed.
Do you have any instructions?
Yes. See the installation guide for the full procedure, and the walkthrough video on the home page.
The tuner also walks you through the installation on its own screen.
How do I use the security bypass cable on my 2018+ RAM?
2018 and newer RAMs require bypass cable #42215, and you must use it. It comes with a replacement OBD box and USB cable.
Replace the OBD box that comes with the Mini Maxx with this bypass version, the one with the red stripe. You will only use this red-striped OBD box on 2018 and newer RAMs.
Connect one end of the USB cable into the port on the side of the OBD box, and the other end to the green connector behind the dash, into the fifth port down on the connector closest to the driver's seat.
Do not update the Mini Maxx with BD software. Those instructions are only for their tuners.
Why do I have Error 294?
Error 294 means you are attempting to install the tuner on an unsupported vehicle.
You are most likely trying to install it on a 2010 to 2012 RAM 4500 or 5500, which are not supported.
Can the Mini Maxx V2 be unlocked?
No. The Mini Maxx V2 cannot be remotely unlocked.
Can I use your update on the V1?
No. Do not use the V2 update on a V1; it will make your V1 inoperable.
We do not have any files for the V1.
Does the Mini Maxx need to stay plugged in after I tune my truck?
No, the tuner does not need to stay plugged in.
If you remove it, the tuner will default back to the no power tune level after a few drive cycles. It will not remove the delete tuning; the truck will simply run at the no power level.
Where do I wire the fuse tap?
You will need to find a fuse that gets switched ignition power: 12V with the key in the ON position, and 0V with the key OFF.
Why does my tuner say "warm up mode"?
Engine warmup mode limits power until temperatures are up to the operating range. This is controlled through the defueling parameters.
You can check and adjust these settings as you see fit, under Menu, Vehicle Setup, Defueling.
