Frequently Asked Questions (FAQ)
Q1: Are ECM and ECU the same thing?
They are often used interchangeably. In heavy equipment, ECM usually refers to engine control, while ECU can describe any electronic control unit managing engine or vehicle systems.
Q2: Do ECMs & ECUs need programming?
Yes. Many units require calibration or programming to match the engine, injectors, and emissions system.
Q3: Can a faulty ECM damage my engine?
Yes. Incorrect fuel delivery or timing can lead to poor performance or engine failure if not addressed.
Q4: Do you supply plug-and-play units?
Yes, where possible. We also offer pre-programmed ECMs & ECUs based on your engine data.
Q5: Do Beehire ECMs & ECUs come with warranty?
Yes. Warranty terms depend on the product type (OEM, aftermarket, or remanufactured).
