A method for adaptation of a detected camshaft position of a camshaft in an internal combustion engine with: Detection of an ACTUAL gas signal in a gas space that is associated with the camshaft and is associated with a detected camshaft position; Processing of the gas signal to produce an ACTUAL gas criterion; Modeling of multiple simulated gas criteria, each of which is associated with a target camshaft position; Determination of a simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of an ACTUAL camshaft position that corresponds to the simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of a camshaft position correction value from the difference between the ACTUAL camshaft position determined and the detected camshaft position; Determination of corrected camshaft positions by correcting the detected camshaft positions with the camshaft position correction value.

Disclosed is a method for calibrating a crankshaft sensor, of the type including a crankshaft wheel and a sensitive element facing the latter, during replacement of the crankshaft sensor, including the following steps: saving an old angular position of a camshaft sensor wheel relative to the crankshaft wheel, which is achieved using the old crankshaft sensor, replacing the old crankshaft sensor with a new crankshaft sensor, determining a new angular position of the same camshaft sensor wheel relative to the crankshaft wheel, which is achieved using the new crankshaft sensor, correcting the measurement of the crankshaft sensor by applying an offset equal to the difference between the new angular position and the old angular position.

A sobriety ignition interlock system including an engine control device and a method for managing available vehicle engine power using the sobriety ignition interlock system. The engine control device includes an engine control processor (ECP) that is electronically connected in between an engine control unit (ECU), an engine sensor assembly, and a sobriety processor. The sobriety processor determines a sobriety level of a vehicle driver and sends a corresponding sobriety signal to the ECP. The ECP intercepts an engine signal transmitted from the engine sensor assembly to the ECU and manipulates the engine signal according to the sobriety signal, in order to manage the available power of the vehicle engine.

An apparatus intercepts and modifies sensor signals generated by vehicle sensors and provides the modified signals to an engine control unit in the vehicle. The engine control unit is configured to receive the modified sensor signals and generate engine control signals based thereon. The apparatus includes a fuel composition sensor and a fuel control module. The fuel composition sensor senses characteristics of fuel in the vehicle and generates a fuel composition signal based on the sensed characteristics. The fuel control module, which intercepts the sensor signals from the vehicle sensors, includes a processor programmed to generate modified sensor signals based on the intercepted sensor signals and the fuel composition signal. Based on the modified sensor signals, the engine control unit optimizes the performance of the engine for a given ratio of alcohol to gasoline in an alcohol/gasoline fuel blend.

A throttle-controlled intake system is disclosed that provides a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle-controlled intake system includes a control module that is coupled with an aircharger air intake. The control module processes input signals from a throttle pedal of the vehicle and sends modified throttle position signals to a throttle body of the vehicle so as to increase throttle responsiveness of the vehicle. The throttle-controlled intake system further includes a wiring harness and a signal adjuster. The wiring harness electrically couples the control module with the throttle pedal and the throttle body. The control module sends signals directly to the throttle body of the engine, bypassing an electronic control unit of the vehicle. The signal adjuster includes a rheostat that enables manual adjustment of the throttle responsiveness of the vehicle.

The invention involves a system and method for providing a liquid fuel or a liquid and gaseous fuel to a diesel or Otto cycle engine for operation of the engine. The system includes a primary electronic control module (ECM), which monitors engine sensors and contains a first three-dimensional fuel map for the liquid fuel. A second ECM is connected for bi-directional transfer of information to the first ECM, the second ECM contains a second three-dimensional fuel map for delivery of the gaseous fuel through a secondary gaseous fuel injection assembly. The bi-directional communication between the two ECMs while monitoring the engine sensors allows both ECMs to learn an efficient fuel map for delivery of both fuels in the same cycle for improved efficiency, reduction in slip and lower emissions.

An engine simulation system and method for replacing an original engine in an existing system of a piece of equipment, including an engine controller from the original engine, a new engine having an engine controller, and a simulator module connected between the engine controller of the new engine and the engine controller of the original engine. The simulator module is configured to simulate that the original engine is still in the existing system.

A horsepower on demand system is presented that facilitates a user to purchase additional power from a third party provider. The system includes a vehicle with an engine, a control system, a microprocessor, memory and software and a wireless communications module. The system also includes a third party provider having a module, a database, software, and an interface. When a user purchases additional power from the third party provider, the third party provider transmits a control signal over a wireless communications network to the vehicle and the vehicle's control system modifies the operational characteristics of the motor thereby increasing the power output.

Present embodiments provide a throttle body which may be used with a variety of engines of different manufacturers. The throttle body may be used to replace mechanical or hydraulically controlled carburetors with electronic fuel injection. The throttle body may provide improved fuel pathways through and about the throttle body in order to move fuel to opposed side. The throttle bodies may have improved configuration of the fuel injectors. Further, the throttle body may have computer mounted on the throttle body and a notch formed in the throttle body to define a wire routing pathway from the computer to the injectors.

Methods, apparatus, systems, and computer-readable media are provided for employing a mode expansion module to increase a number of operating modes in which a vehicle can operate. The mode expansion module can operate as a computing device, which can be connected to an existing vehicle for sending and receiving both sensor signals and engine control signals. The mode expansion module can be controlled by a user using an existing vehicle control switch that is connected to the vehicle, and can leverage connections to an existing display panel in the vehicle in order to indicate to the user the operating mode that has been selected. Furthermore, when a particular mode of the mode expansion module is selected, the mode expansion module can modify control commands being transmitted from an existing engine control module, and/or modify sensor signals being provided to the existing engine control module.
