Driven By Results

BenchForce has emerged as the industry leader in ECU programming hardware as a result of our American-made, reliable, and purpose-built products that simplify and streamline automotive module work. Whether you’re a professional or a DIYer, our mission is to provide you with an efficient path to bench-testing, diagnosing, and reprogramming electronic control modules.

OE-Grade Quality

Easy to Use

Consistent Results

Application Versatility

Unrivaled Selection

We've made BenchForce shopping easy. Simply choose a BenchForce Starter Kit, the ECU harnesses you need for the vehicle you're working on, and then verify that your programming interface device has an OBD-II or J1939 9-pin diagnostic link connection. If you can connect to a vehicle, you can connect to PowerBlock.

PowerBlock™ II - Vehicle Wiring. Simplified.

BenchForce™ PowerBlock is the central hub for powering up an ECU on the bench. PowerBlock simplifies your entire wiring harness into a single, CNC-machined billet aluminum enclosure. PowerBlock can handle just about any bench programming using Pass-Through Harnesses, including OBD-II, FEPS, SCP, SCI, and Heavy Duty J1939 applications. Connect your USB or serial laptop-to-vehicle programming interface to PowerBlock's OBD-II diagnostic connector, and then choose from the growing selection of BenchForce ECU harnesses.

PowerBlock™ IV - ROM Boot Support

To provide for the Cummins ECU ROM Boot (sometimes called BootROM) feature, we added a momentary switch to the face of the PowerBlock II, anodized the housing red, and created PowerBlock IV.

PowerBlock IV supports OBD-II and all other protocols that PowerBlock II supports, and is also well-suited for J1939 due to its included ROM boot switch for Cummins ECUs.

4 Simple Connections

In a few simple steps, you'll be ready to connect your programming interface tool to PowerBlock's OBD-II diagnostic connector.

J1939 9-Pin Support

J1939 programming tool support is available with the use of our OBD-II to Black J1939 9-Pin Data Link Connector Harness. ECUs that support both OBD-II and J1939 need only change the pass-through harness for dual protocol compatibility!

PowerBlock's OBD-II 16-pin DLC follows industry standards. J1939 9-pin DLC has no standard. It is important to verify the proper 9-pin DLC pin layout to ensure compatibility with your programming interface tool.

American-Made Solutions

BenchForce is headquartered in Erie, Pennsylvania, in the heart of the Rust Belt. We manufacture and assemble adapters, harnesses, and PowerBlock in-house. BenchForce builds its products from high-quality materials and designs them for durability and reliable performance.
