In need of more power?
This is a question that we get asked quite often. If you are in a situation where you feel like the machine you have is lacking in the horsepower department, we can help! When it comes to horsepower increases, the best way to explain it is that we are making the engine more efficient. It produces more power, sooner. When operating the equipment, it will take less load on the engine to get up to speed. This reduced the overall load on the engine, and as a result reduces the amount of fuel required. If there is a situation where more power is needed, you’ll have the extra horsepower available to you! It really is the best of both worlds.
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!
What is software tuning?
Software tuning is customized engine management, that is flashed onto your engine control module. This results in an increase of horsepower and torque, while reducing the overall engine load - this helps reduce fuel consumption. Improved torque makes the vehicle more responsive while working with heavy loads. It can also be used to reflash the emissions system that is equipped on a piece of equipment. Some applications have to come to our shop directly to be tuned, however the majority of the equipment on the market today is supported through our handheld device!
Which vehicles can be tuned?
We can optimize modern tractors, harvesters, combines, sprayers, construction equipment, and just about anything else with a diesel engine! While we have the capability of tuning just any diesel engine on the market today, we specialize in agriculture and construction equipment.
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.
