Cooling Fan In-Rush Current and how to control it with a PDM

Posted by Tony eigenseher on

In-rush current refers to the sudden surge of current that occurs when an electrical device is turned on. In the case of a cooling fan, in-rush current can occur when the fan is first powered up and the motor starts to spin. The in-rush current for a cooling fan will depend on several factors, including the size of the fan, the voltage and current rating of the power supply, and the design of the motor. Typically, the in-rush current for a cooling fan can be several times higher than the normal operating current. It's important to take the in-rush current...

What is a PDM and why do I need one?

Posted by Tony eigenseher on

A Power Distribution Module: The Backbone of a Vehicle's Electrical System A Power Distribution Module (PDM) is a critical component of a modern vehicle's electrical system. Acting as a centralized distribution point for electrical power, it simplifies the wiring and connections required for various electrical systems in the vehicle. This results in reduced complexity, enhanced control, and monitoring capabilities, and increased reliability and safety. In this article, we will discuss the benefits of PDMs, the components and types of PDMs, and their installation and maintenance.

Why you should use a CAN Lambda Sensor

Posted by Tony eigenseher on

A CAN LAMBDA sensor, often referred to as an oxygen sensor, measures the level of oxygen in exhaust gases. This level is critical in obtaining the optimal air fuel mixture when tuning an engine. CAN refers to the Controller Area Network which acts as the ‘nervous system’ of a vehicle, enabling communication from one part to another. The lambda calculation determines the ratio between the amount of oxygen actually present in the exhaust compared to the amount that should have been present to obtain perfect combustion.  This air fuel ratio information which the CAN Lambda provides is essential for a tuner. The fuel input, power output and air fuel ratio...
