Mini Maxx Tuner V1 | DPF / DEF / EGR Delete Tuner for 2003-2014 Powerstroke / 2007-2014 6.6L Duramax / 2006-2012 Cummins

Mini Maxx Tuner V1 for 2003-2014 Powerstroke / 2007-2014 6.6L Duramax / 2006-2012 Cummins

The Mini Maxx Tuner V1 is a handheld engine performance tuner. It connects directly to the ECU (Engine Control Unit) via the vehicle's OBD-II diagnostic interface, exchanging data and rewriting programs. Its core purpose is to modify the original ECU program to achieve the following:

• Disabling related fault monitoring functions and preventing warning lights from illuminating after physically removing components such as DPF, DEF, and EGR.
• Rewriting parameters such as fuel injection and boost pressure to increase engine horsepower and torque.
• Reading sensor data from the ECU in real time and displaying it as a digital instrument cluster.
• Reading and clearing fault codes for basic diagnostics.
• Modifying the vehicle speed signal to match non-original tire and gear sizes.

Compatibility

Not Compatible: 2015+ diesel models from the brands above, all gasoline-powered trucks, and any trucks or SUVs not listed in the table.

Main Applications

Emissions System Removal

Supports complete software-level masking of related fault codes after removing components such as DPF, DEF, and EGR, allowing the engine to operate normally.

Performance Enhancement

Provides multi-level adjustable power upgrades from 0 to 250 horsepower, releasing torque limited by the factory program.

Safety Monitoring

Uses built-in sensors to monitor critical data such as EGT, boost pressure, and oil temperature in real time, and automatically intervenes to protect against danger.

Data Calibration

For modified large tires or changed gear ratios, recalibrate the speedometer to ensure data accuracy and correct transmission shift logic.
