One or more techniques and/or systems are disclosed for automatically obtaining a profile for a set of accelerator pedal position sensors in a target vehicle. The profile can comprise a correlation of the position of the pedal to an output signal for one or more sensor in the set of sensors. A pedal position sensor signal reader can be used to automatically detect signals from one or more pedal position sensor in the target vehicle's accelerator pedal, while the pedal is released, depressed, and moving between the released and depressed positions. A pedal profile can be automatically generated using the output signals and corresponding pedal positions. Obtained data can be used to program a speed control device for the target vehicle. Correlated output can be used to adjust the speed of the vehicle by sending an emulated signal to the ECM, which may adjust the speed control system.

One aspect provides a method including determining that an absolute pressure sensor is not submersed in a fluid; measuring an atmospheric pressure with the absolute pressure sensor to determine an offset pressure measurement; submersing the absolute pressure sensor in a fluid; and measuring pressure with the absolute pressure sensor; wherein a compensated pressure measurement of the fluid is determined. Other embodiments are disclosed.
