Wideband Display

This is the construction guide for the 5301 wideband fuel mixture display kit. The 5301 is the Tech Edge version (rather than the Jaycar version) of the modified Silicon Chip FMD design, and it features, compared to the original kit, double sided PCBs, a new front panel design, in-built RS232 output, and superbright GaAlAs 7 segment LEDs. The 5301 uses the same version 1.1 software as the 5300 and, unless noted otherwise, is known elsewhere on this website as the 5300 unit or the modified FMD display.

The 5301 wideband fuel mixture display kit is designed to provide accurate readings of the air-fuel mixture in automotive applications, enhancing engine performance and efficiency. The kit incorporates a double-sided printed circuit board (PCB), which allows for a more compact design and better routing of signals, reducing interference and improving reliability.

The front panel of the 5301 features a modern design that enhances usability, with clearly marked controls and indicators. The superbright GaAlAs (Gallium Aluminum Arsenide) 7-segment LEDs ensure visibility under various lighting conditions, making it suitable for use in vehicles where ambient light can vary significantly.

The inclusion of an RS232 output allows for easy integration with external devices such as laptops or diagnostic tools, enabling real-time monitoring and data logging of the air-fuel ratio. This feature is particularly beneficial for tuning and adjusting engine performance.

The software utilized in the 5301 is version 1.1, which is also compatible with the 5300 unit. This ensures that users can benefit from the same functionalities and updates across both models. The modified FMD display provides enhanced data accuracy and responsiveness, making it a valuable tool for automotive enthusiasts and professionals alike.

Overall, the 5301 wideband fuel mixture display kit represents a significant advancement over its predecessors, combining modern technology with user-friendly features to deliver precise and reliable performance monitoring for fuel mixtures in internal combustion engines.This is the construction guide for the 5301 wideband fuel mixture display kit.
