At the heart of the Truck Edition module is an embedded micro-controller that constantly monitors specific engine parameters, up to 100,000 measurements per second! It then utilizes the latest digital signal processing techniques to calculate new performance enhancing parameters and relay these to the engine’s control computer in real time, resulting in improved performance without re-flashing or modifying the engine’s programming in any way.

Agricultural Diesel Solutions Light Duty Truck Edition modules are easy to install and come with complete installation instructions with color photos. The module has a sealed design to protect against non-uniform temperature gradients, humidity, corrosion and vibration. Only electronic components meeting industrial temperature performance are incorporated. Electronic design methodologies, technologies, and materials are selected to achieve minimal susceptibility to voltage spikes and glitches induced by environmental electromagnetic interference and severe duty environments. All electrical connections between circuit boards, switches, and wire harnesses are directly soldered. This eliminates potential corrosion-induced high-impedance connections, like opens, shorts, and partial or intermittent connections. Electronics are potted in a slow-cure epoxy compound. All selector switches which are not potted are of an inherently sealed design.

“Hello, I purchased the Ag Diesel Solutions 20300 performance module from Parleys Diesel and just installed it on my 2001 Newmar motorhome’s Cummins ISB 5.9-260 VP44; the results have dramatically exceeded my expectations. I was looking for improved on-ramp power/acceleration as well as better performance (less slow down) on grades. I got both and then some! The motorhome now drives like a big diesel SUV: fast off the line and actually accelerates up medium grades. Better fuel economy would be icing on the cake. Thanks to Parleys and ADS for such a superb solution!” - T. Ryan.
