How to Delete EGR from ECU

How to Delete EGR from ECU

In this post, you will learn how to delete EGR from ECU. But first, let’s make a little introduction. The EGR valve takes some exhaust gases and puts them back into the engine through a special system. This process helps the engine produce fewer emissions. However, it can eventually cause a carbon deposit buildup in different engine parts, including the EGR shutoff and intake manifold.

Now, you need to know about an EGR Cooler. This device cools down the exhaust gases before they go back into the engine. As a result, it helps to make the process smoother.

How to Delete EGR from ECU

So, the preliminary steps involve preparing the ECU for EGR Removal Leave the ECU valve open for some time. Rinse the CNG pellets in the cylinder with water. Before proceeding, disconnect the positive electrical connection from the ECU. Ensure that both the positive and negative connections are cut. If you face issues with an ECU tuner, refer to the user manual. Do note that EGR delete can be both good and bad. That said, follow these steps to delete EGR from ECU:

1. Access the Internal Valve

Remove the two screws securing the ECU’s lid. Depending on your ECU model, you might need to unscrew a pin or use tools like a knife or screwdriver to gain access to the valve.

Once accessible, disconnect the wiring from the connector and find the two valve screws. Proceed to remove these screws.

2. Replace the EGR Valve

Peek inside the valve and extract the black plug. Subsequently, remove the gasket that covers the valve body. With this gasket removed, you can now take out the old ECU valve. When you’re adept at this process, you’ll observe that the valve body is now open. If your gasket is held in place with two screws, ensure you remove them.

You might sometimes need additional tools or effort for this step. After taking out the gasket, you can put in the new one and bolt it down. Securely fasten the new ECU valve into its position. Prior to shutting the valve, verify that the drain hole aligns correctly.

3. Reassemble and Finalize the Procedure

As you reassemble, be attentive to the fact that your valve might have holes on its two sides. These holes must align in the same direction.

If you need to remove any screws during this phase, use pliers with a gentle touch. Replace the gasket if required, and make sure all screws are tight.

Reconnect your battery afterward. Power up your ECU and check its power levels. If you don’t see any power, consider replacing the battery or re-examining the connections.

4. Check the Side Connectors

Inspect the side connectors meticulously. Examine the wiring to ensure there’s no damage or looseness. Use a magnifying lens if necessary to inspect the connectors for any signs of wear, frayed wires, or cracks in the seals. A properly working valve will have robust and well-sealed connections.

5. Addressing Sensor Issues

If your device indicates a depleted sensor, it’s an indication that the ECU’s level is too low during draining. First, assess the connections between the valve body and the drain.

If the seal remains intact, position the new valve and remove the older one. If you notice any damage to the drain connection, think about replacing the valve.

6. Maintenance and Care

As you delve into the process of EGR removal from the ECU, it’s paramount to maintain your equipment. An ECU typically has a finite number of connections, and poor maintenance can lead to malfunctions. For detailed maintenance guidelines, refer to the manual specific to your model.

How to Fool the ECU

Despite claims that the delete is unlikely to cause a check engine light (CEL), you may still experience a CEL every time you start the car. It could be that the sensor is now running as an open circuit, which the ECU detects. So, is there a resistor or a method you could use to fool the ECU into thinking everything is functioning correctly?

  1. If you plan to modify the car further, you should get an accessport and have a tuner delete the CEL. Otherwise, the only option might be to plug the EGR back in and let it hang in the engine bay.
  2. A temporary solution could be plugging the pump in and attaching a hose to it. The best solution, however, is the Cobb accessport, where a tuner can disable the CEL. They’ve seen relays work for VCTS but nothing for the EGR.

Should I Delete My 6.0 Powerstroke?

If you remove the EGR system from your 6.0L Power Stroke engine, the exhaust gas will get hotter. Normally, this engine sends the exhaust gases back to make the car work better.

When you shut off the EGR system in your 6.0L Power Stroke engine, the exhaust gases get hotter. Normally, these gases are sent back into the engine to make the car work better.

What Does a EGR Delete Do on a 6.7 Cummins?

Deleting the EGR on a 6.7 Cummins means taking it out using a special kit. This can make your 6.7 Cummins work better, use less fuel, and need fewer emergency repairs for the EGR or the engine.

Other Engine Types

GM Trucks 2006-2010 with 6.6L Duramax (LBZ & LMM)

This upgrade typically includes a custom pipe that replaces the entire cold side intercooler pipe and throttle plate. It ensures that the pipe stays in place thanks to a carefully cut flange and a bent tab for proper positioning.

To complete the installation, it may come with a TIG-welded fitting for the map sensor, a 3/4″ coolant re-route line, and one 1/8″ NPT fitting for boost, water meth, or nitrous.

Trucks from 2004.5 to 2005 with GM Duramax LLY engines.

The Sinister Diesel LLY Duramax EGR Delete Kit is for Chevy 2500 and 3500 HD trucks from 2004 and 2005. It swaps out the regular EGR Valve and Cooler.

This change is made for the 6.6L LLY Duramax engine. It makes the exhaust flow better, which means the turbo spools up faster and the engine stays cooler.

Complete Duramax LML EGR Delete Kit for Your Duramax LML

The Duramax LML EGR delete kit helps trucks use less fuel. It takes out the EGR system, which can harm the engine due to exhaust gas buildup. With this kit, the truck runs better and more efficiently. EGR is like a control system for the air going into engines and the gases coming out in moving cars.

Conclusion – Delete EGR from ECU?

You may have to choose between EGR delete or bypass options. The EGR valve, or Exhaust Gas Recirculation valve, is a pollution control device designed to reduce NO2 emissions to meet strict European Emission Regulations. EGR Delete and EGR Bypass software are made to turn off this valve and solve any running problems it might cause.
