In Line Modules for Cummins, Duramax and Powerstroke Diesels

What In Line Modules Cover

In line modules connect to factory sensors or harnesses and modify inputs within manufacturer limits for supported applications. The catalog includes aFe SCORCHER modules plus specialty control products for diesel and turbocharged vehicles.

Module vs ECU Programmer

An in line module usually stays connected between a sensor and the factory harness. A handheld programmer or flash tuner writes a calibration to the ECU. Choose the approach supported by your exact vehicle and goals.

Diesel Truck Applications

Diesel modules are common for Cummins, Duramax, Powerstroke, and other turbo diesel engines. Some focus on power delivery while others work with fuel rail pressure or boost related signals.

Supporting Modifications

Fuel system condition, air filtration, exhaust flow, transmission health, and monitoring equipment matter before increasing output on a working truck.

Gas and Turbo Applications

The selection also includes modules for HEMI trucks, turbo GM trucks, Tacoma and 4Runner turbo applications, Nissan, Subaru, Mazda, BMW, Audi, and Kia models. Fitment is strictly vehicle and engine specific.

Bluetooth Control

Some modules offer mobile control for selecting power levels or monitoring supported values. Follow the maker instructions and never change settings during unsafe driving conditions.

Installation and Legal Notes

Install only with the ignition off and a healthy battery. Route harnesses away from heat and moving parts, then inspect every connector before startup. Follow local laws and manufacturer instructions for emissions related products.

Verify Before Ordering

Confirm model year, engine, fuel type, transmission, and factory sensor connector. A diesel module for a 6.7 Cummins does not cross fit a gasoline HEMI or a Duramax.

Common Questions

What is an in line performance module?

It is an application specific device that connects to factory wiring or sensors to adjust supported signals for a change in vehicle response or power delivery.

Does an in line module flash the ECU?

Usually no. These modules commonly work through external harness connections. A flash tuner writes a calibration to the ECU.

Are diesel modules vehicle specific?

Yes. Confirm the exact engine, model year, connector, and truck configuration before ordering.

Can I use a diesel module on a gas truck?

No. Diesel and gasoline applications use different engine controls and hardware. Order only the module listed for your exact vehicle.

Do I need supporting parts for a diesel module?

That depends on the power level and vehicle condition. Good maintenance, proper monitoring, and a healthy transmission are important on high torque applications.

Can I remove a module before service?

Follow the manufacturer instructions. Many modules can be disconnected, but preserve original connectors and avoid forcing clips.

Will a module work with other tuners?

Compatibility varies. Do not stack tuning products unless both manufacturers explicitly support the combination.

Do Bluetooth modules need a phone connection to run?

Not always. The phone may be used for setup or adjustment, while the module can continue operating with its selected setting.

How long does installation take?

Simple plug in installations can be quick, but access and routing vary by vehicle. Read all instructions before beginning.

Can Black Ops Auto Works help with module fitment?

Yes. Provide your vehicle year, model, engine, fuel type, and current modifications for fitment help.
