Tuning Options: 
We have the ability to flash John Deere equipment via our handheld device, or by bench flashing the engine control module. The Reflash Master handheld device is a great way to flash the engine control module (ECM) remotely. This allows Customers to bring the device to the machine, and have the ability to read and write the ECM on site. Bench flashing is a great alternative to the handheld device, this option is available if there is no way to reset the soot levels on site. If a machine is in derate due to high soot levels in the diesel particulate filter, please select the Bench Flashing option. This will allow us to write the ECM, and reset all soot levels while the control module is on the bench. On rare occasions, there may be a situation where the handheld device cannot connect properly to the engine control module due to an overload on the can bus system. This affects the modified file being written onto the control module. When this happens, the engine control module will have to be shipped to us for bench flashing in order to complete the tune. If you have any questions about which option is right for you, please feel free to reach out;

Reflash Master Handheld Device:
After receiving the handheld device in the mail, 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 via email. Once the MOD file has been written to the Motor Grader, it's ready to go! This starter kit includes everything you need for tuning including our handheld device with quick reference guide and TeamViewer software in case technical support is required during the tuning process.

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 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.
