![]() ![]() We will not provide tuning in your registered, factory vehicle with any types of deletes or non emissions compliant tuning. We do not support late model integrations, only swaps into vehicles prior to 1998. Intended for off-highway competition use only. This is where our nearly 2 decades of Duramax experience comes in. Potentially the most important piece of the puzzle is a having the proper ECM calibration to not only work with your specific application (trans type, emissions equipment, intake/exhaust) but also with the goals of your vehicle (race, show, tow, marine). Similarly our wiring harnesses and electrical systems facilitate a clean trouble free install. In order to power your project with a Duramax Diesel, it is important to upgrade the drivetrain components to handle the massive power and torque generated. If you are interested in our standalone harness you can follow our ordering guide, purchase your harness modification a well as the ECM and TCM tunes and we can certainly get it running and driving properly for you. The CTS3 monitor can be used as a gauge cluster as well. We recommend the latter if you’re planning to use the OBD continually for anything else because the signal isn’t always strong enough on an OBD splitter to run two devices. The harness will retain the OBD port, so you can use that for your gauges or use some of the harness pigtails and add an oil pressure and coolant temp sensor to wire them directly. Gauges: We offer a 10% discount on any available Dakota Digital products with the purchase of our harness (contact us with specific product requests). We recommend aftermarket HVAC, controls and dryer at least. You can still leverage any of the factory AC components you’d like but it will be controlled separate from the harness. You will be responsible for wiring your owner starter circuit with neutral safety and your own AC circuit if you are wanting AC. Tow-Haul Mode, Tap Shift, Electric Transfer Case Shifting, Axle Engagement, Duramax Idle Up, Fled Fuel, Starter Solenoid Control, Park-Neutral Starter Interrupt, Shift Interlock, AC Compressor Clutch Control, AC Req Idle-Up, AC Req Fan Control, Cruise Control, Vehicle Lighting, Donor Vehicle Gauge Clusters or any other donor vehicle features/conveniences. Due to the complexity of modern vehicles and their control systems, donor vehicle functions, conveniences or “nice to haves” are not offered or supported in any way as follows: Your harness is set up for standalone use only which in basic terms means the engine will run and the transmission will function. You will not retain control of the AC, tow haul or any other factory features that are controlled through the BCM. It doesn’t mean it can’t be done, just that we don’t support it. This includes any integration with any factory gauges, factory body harnesses, etc. We do not support Duramax integration into late model vehicles. At the time of check-in, the harness will be inspected and subject to additional charges (either mandatory or suggested) if there are any issues with wires, corrosion, pins or connectors. For the ’11 model year, a detuned version of this engine with 260 hp and 525 lb-ft of torque, called the LGH and mated to the 6L90 automatic, was added to the powertrain options for the Chevy Express and GMC Savana vans.Lead time on harness conversion is generally 4-5 weeks from the time it is received and checked in. This exhaust brake has different modes of operation when the truck is in Tow/Haul mode or when the cruise control is activated. The LML also added a “smart” exhaust brake built into the turbo, which is activated by the driver using a button on the center console. The new engine design also came with a B20 rating, allowing owners to use fuel blends with up to 20 percent biodiesel content without voiding their warranty or risking damage to the engine or fuel system. This was accomplished with the use of multiple new features, including super-fast-reacting piezo-controlled injectors (which are capable of multiple injections per cycle for optimal combustion), a ninth injector mounted downstream from the turbo to help DPF regeneration, a new EGR system with a cooler bypass, and a new selective catalytic reduction (SCR) system with urea injection. Once again, engineers were able to squeeze out another 105 lb-ft of torque while making the engine run dramatically cleaner than the previous generation. 2010 to Present – The current version of the Duramax, known as the LML, brings to market a massive 397 hp and 765 lb-ft of torque and meets the most stringent emissions laws to date. ![]()
