How to Tune and Delete Eco Diesel and Sprinter with Bench Flash or Flash Tuner

How to Tune and Delete Eco Diesel and Sprinter with Bench Flash or Flash Tuner

Tuning your Eco Diesel or Sprinter to remove emissions components, like the DPF, EGR, and SCR, can significantly improve performance. Whether you choose a bench flash or a flash tuner, each option requires a certain degree of knowledge to get the job done properly. Let’s break down these methods and how they work.

Bench Flash: The Mechanical Approach

For those comfortable with a bit of mechanical work, the bench flash might be the best option. It requires you to physically remove your vehicle's ECM (Engine Control Module) and ship it to us for tuning. Here’s the basic process:

  1. Clear All Codes: Make sure there are no engine or emissions codes before removing your ECM. This is especially important for vehicles with DEF/DPF countdowns, which may not be cleared through the ECU tune.

  2. Turn Off the Engine: Make sure the ignition is off, and disconnect the negative battery cable.

  3. Remove the ECM: Access the ECM by removing the air intake and disconnecting any necessary components.

  4. Ship Us Your ECM: After ordering, we’ll provide a shipping label so you can send your ECM. The entire process, including shipping and tuning, typically takes 4-11 days.

  5. Receive and Reinstall: Once you receive your flashed ECM, install it, and disconnect sensors for emissions systems that are no longer needed, such as the SCR and exhaust sensors, except for the primary O2 and EGT sensors.

The bench flash process involves manual labor but is simple for those without technical tuning skills. It’s often faster because you only need to reinstall the ECM after the tuning is complete.

Important Notes

  • When you purchase this bench flash, we will send you an order confirmation. Be sure to include your order number, truck year, chosen tune option, and contact information when shipping your ECM. If this information is missing, it will delay the process.

  • Before removing your ECM, make sure to clear any DEF/DPF-related errors. These codes must be addressed before tuning as ECU tunes rarely clear SCR module codes.

Flash Tuner: The Digital Approach

For those more comfortable with computers, the flash tuner is the go-to option. This method eliminates the need to physically remove the ECM, but it requires technical knowledge of software.

  1. Install Software: We’ll send you a flash tuner device. You’ll need a laptop with Windows and software installed to extract your factory calibration.

  2. Extract & Send Calibration: Using the flash tuner, connect the device to your vehicle’s OBD port and extract the calibration. Send us the extracted data.

  3. Receive Modified Tune: Once we modify the calibration, we’ll email the new tune back to you.

  4. Install the Tune: Load the new tune onto your vehicle via the tuner device. This process requires careful attention to the instructions to avoid complications.

While this method avoids physical mechanical work, it does require more technical skills. It’s essential to follow every step accurately to prevent any issues during the process.

DPF, EGR, and SCR Removal

Regardless of which tuning option you choose, removing the DPF, EGR, and SCR is necessary to complete the delete. Our kits make this process easier, providing all the necessary pipes and hardware. For example, for Jeep Ecodiesel models like the Wrangler or Gladiator, the pipes connect in a specific sequence:

  1. Pipe A connects to the turbo outlet.

  2. Pipe B connects to Pipe A and Pipe C.

  3. Pipe C connects to Pipe B and the factory exhaust.

 

Each pipe is essential to the delete process, and we provide diagrams to help orient the parts correctly for your vehicle. 

Step-by-Step Bench Flash ECM Removal

  1. Clear all codes from your vehicle.

  2. Turn the key to the off position. {Dash lights On, Engine OFF}

  3. Disconnect the negative battery cable.

  4. Remove the ECM by taking out the air intake to access the ECM.

 When you receive your ECM back after tuning:
  1. Unplug the connector in the engine bay.

  2. Disconnect the SCR module located under the truck.

  3. Disconnect all exhaust sensors except for the Primary O2 and EGT sensors.

Choosing the Right Option for You

If you feel more confident handling mechanical tasks, go for the bench flash. It minimizes the risk of technical errors, and all you need to do is reinstall the ECM after tuning. If you are more comfortable with digital tools, the flash tuner is a great choice, allowing you to tune your vehicle without getting under the hood.

Whichever route you take, ensure you understand the process fully before starting. Always clear all codes before tuning and follow the instructions carefully to achieve the best results. If you’re unsure, our detailed guides or a trained technician can help you out.
