Reflash Master Handheld Device:
Our Reflash Master handheld tuner makes tuning possible in four easy steps. First, after receiving your handheld device, it is ready to take a read of the ECM on the Tractor. After sending the read file, we have a turn around time of 2 hours before sending your modified (MOD) file back to you for writing to your tractor. Once the MOD file has been written to the Tractor, it's ready to go! Also included in our kit is the Reflash Master Client software, Quick Reference Guide for the handheld device, and TeamViewer software.

What is an EGR System, and why remove them?
Exhaust Gas Recirculation (EGR) is a method that is used to control Nitrogen Oxides (NOx) emissions. The purpose of this system is to return a small portion of exhaust gases back into the combustion chamber through the intake manifold. Lowering combustion temperature, resulting in a reduction of NOx emissions. The issue with EGR systems is that the valve can stick open due to carbon deposits. A worst case scenario is that the EGR becomes completely blocked, this will result in poor fuel mileage and a loss of power. When this occurs, it results in engine warning lights and the equipment going into limp mode. The vast majority of exhaust gas recirculation valves power off in the closed position. This means that once they are de-energized, they are in the shut position. On a few select applications, we offer block off plates. These plates are used as a fail safe, to ensure that there is no exhaust coming back into the intake system. 

What is a DPF System, what do you need to do with it?
The diesel particulate filter, or DPF is part of the exhaust aftertreatment system. It’s main purpose is to trap particulate matter, such as soot. This soot has to be periodically burned off, which regenerates the filter. When the soot level reaches a high enough percentage, the engine starts to inject fuel directly into the exhaust system. This creates heat and converts soot into carbon dioxide. Having to deal with regen can cause down time for the machine. In some cases, the DPF will have to be replaced, or cleaned manually. Not to mention it is also extremely restrictive on the engine's ability to push air out. When it comes to removing the DPF canister, the only decision you have to make is whether you hollow it out or straight pipe it! 

Emissions Removal:
Custom emissions system reflashing is a popular option. We can provide customers that are experiencing costly downtime and high fuel consumption emissions solutions for machines that are on or off warranty. Through custom tailoring of the engine control module, we can remove the exhaust gas recirculation, diesel particulate filter, and diesel exhaust fluid (also known as UREA). This will increase the machine's overall efficiency and reliability!  

Emissions tuning is for off-road use only. Please consult your Provincial or State legislation, as this product may not be street legal. Removal of emissions systems cannot be performed on vehicles that are registered for highway use. It is up to the Consumer to know and understand their local legislation prior to purchasing.
