In order to complete a reflash on these ECM’s, a specific tool is required. This allows us to gain access to the ECM, and tune remotely. Please select if you require a CAT Comm adapter. These tools are always in stock, and ready to sent out. Specific software is also required for the Comm adapter, the software is included with the purchase of the adapter. TeamViewer will be needed to complete remote tune, along with a strong internet connection.
Tier4A: Exhaust gas circulation (EGR) and diesel particulate filter (DPF) reflash.
Tier4B: Exhaust gas circulation (EGR), diesel particulate filter (DPF), and diesel exhaust fluid (DEF) reflash.
What is DEF?
DEF, or diesel exhaust fluid is a liquid that is injected into the exhaust system. This part of the exhaust system is called the SCR, or the selective catalytic reduction. It is designed to remove nitrogen oxide emissions from the diesel engine. The issue with DEF is that because it is 67% water, it can freeze during the winter. This can crack the DEF tank and lead to other problems. Some manufacturers use DEF as their main, or only, source of emissions control. This can result in high costs, ensuring that the DEF is always full. The catalyst that is used for the DEF is not as restrictive compared to the diesel particulate filter. This means that it can stay in place, even after a reflash has taken place. We recommend that you rinse out the DEF system with water after the fluid has been drained. DEF if left alone for a long period of time can crystalize. That is why it is best to make sure everything is clean!
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.
