![]() Additionally, you will need a USB cable (USB-A to USB-B) to connect your Xcelerator to your computer. PPE knew that Diesel Power Products customers were yearning for real horsepower and torque out of a hand-held programmer and they delivered with the Xcelerator series! The Standard Xcelerator series was specifically designed for 2001 through 2010 Duramax diesel engines and provides four to five power levels of additional horsepower and torque, speedometer corrections (for tire sizes ranging from 25" to 44.75" at 1/4" increments), adjustable speed limiter (from 40 to 96 mph in 1 mph increments or directly to 200 mph), adjustable gear ratio (from 2.73 to 5.13), reads and clears Diagnostic Trouble Codes (DTC) through the vehicle's On-Board Diagnostic System (OBD-II), real-time data scanning for comprehensive engine diagnostics, transmission reset and quick learn feature for faster transmission relearn and includes a Universal Serial Bus (USB) side-plug for easy online updates. 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. We were still getting 1093 codes like crazy and even got the occasional P0087 code (fuel rail/system pressure too low). (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. Sometimes with the edge I would start to wonder when it was going to start fueling defintely a noticeable lag. One thing I noticed is that there is no hesitation between pressing the accelerator and engine response. By feeding both rails, that problem is eliminated. How To Install Ppe Xcelerator Ppe Xcelerator Duramax The power difference is defintely noticeable, the shifts seem a bit firmer. ![]() 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. ![]()
