The DEF system when working correctly does its job, but its so complex with all of it sensors and different modules that all send the CAN signals back to the ECU. These can be very costly to repair with a SCR ECU costing approx 5k, this is why we sell our DEF bypass module.
The good points for removing the DEF from your truck, one it will save you a lot of downtime when the truck goes into limp mode when the DEF system fails. If you have a fleet of trucks that have been imported to your country where DEF fluid is not available, your trucks will fail and lose half the power, this is where our DEF delete module comes in and will fix your truck.
A large fleet of trucks using the DEF system will use a lot of it, this has to be refilled on a daily basis. If the fluid is not properly stored it gets contaminated very easily which will cause all sorts of problems with the truck.
Diesel Exhaust Fluid or DEF for short is a colorless liquid which contains water and Urea solution. This is made to ISO 22241 standard and its names can be different depending on what country your are in. The main name for this is Adblue® which is a trademark term. DEF is used with SCR which means Selective Catalytic Reduction for reducing NOx exhaust emissions.
The DPF is a different thing all together, this is a Diesel Particulate Filter and we do not remove or bypass the DPF. Our DEF Emulator is configured to work with your DPF filter so there is no need to remove it. Some companies out there will tell you it must be removed in order for the DEF delete box to work. We manufacture our own delete kits and make custom software for each box. Whatever machine you have that has the SCR system, we can delete the D-E-F unit.
We now have our DEF delete Cummins box now available.
We will not be held liable for any person or company fitting our DEF delete unit in a country where it is illegal, if you are exporting trucks or machinery to countries where DEF fluid is not available these boxes are for you. Any damage or personal injury related to the use or fitting of our emulator we will not be held responsible. It is up to the buyer to check local laws to see if the box can be fitted.
