![]() ![]() Some of our popular programmers on the Ford 6. Give us a call at 1-888-DIESEL-4 and together we can work on finding the best programmer for your truck. Mostly all programmers will yield some type of fuel enhancements. Now there are some units that are better than others based on what you are looking for, but the first step is deciding what you want out of your truck. ![]() Choosing the right programmer is based on what you are using the truck for and what your main objective is with it. *PPE rates at their horsepower levels at the crank shaft, not the wheels.Īctually there is no “best programmer” for any truck. The heavier the load, the lower the level you’ll want to run. Additionally, you will need a USB cable (USB-A to USB-B) to connect your Xcelerator to your computer. (It’s best to invest in some type of gauges to monitor the vehicles parameters.) Towing may lead to higher EGT’s so the level best for towing will be determined by the size of the load. Online Update for Duramax Economy,Standard and Hot Xcelerators Please fill out a IMPORTANT: Return your vehicle back to 'stock' prior to updating your programmer with this update. Most stock applications running the PPE Xcelerator Standard Power Programmer 1110200 stay below level 3 for daily use. The richer the air/fuel ratio in a diesel, the higher the EGT will be. EGT is also directly related to the air/fuel ratio. EGT is an indication of how hot the combustion process is in the cylinders. We were still getting 1093 codes like crazy and even got the occasional P0087 code (fuel rail/system pressure too low).An EGT (exhaust gas temperature) probe is recommended for all applications with performance modifications such as this. (A twin CP3 system works the same way, only each common rail has its own fuel pump and high supply of fuel.) While on the subject of fuel, we also found a couple of other problem areas once the turbo and modified CP3 were installed. By feeding both rails, that problem is eliminated. The theory behind it is that while the left side common rail has plenty of fuel, the last two injector lines on the right side common rail can starve for fuel under load and with hotter tuning. The dual-feed line feeds the right side common rail straight from the CP3 pump, so both rails are being fed simultaneously with identical pressure. The four injector lines on that rail are fed and a fifth fitting allows fuel to travel from that rail, across the top of the engine and into the right side common rail. On a stock Duramax (LLY and LB7), the fuel leaves the CP3 pump and enters the front of the left common rail. ![]()
