FuelTech O2 (Oxygen) and EGT (Exhaust Gas Temperature) Conditioners are precision-engineered devices designed to monitor and optimize engine performance in high-performance vehicles. These controllers provide real-time monitoring and feedback of crucial engine parameters, allowing racers to fine-tune fuel delivery and ignition timing for maximum power output and efficiency. The O2 controller measures the oxygen content in the exhaust stream, enabling precise adjustment of air-fuel ratios for optimal combustion, while the EGT controller monitors exhaust gas temperatures to prevent overheating and potential engine damage. With advanced features such as data logging and programmable alarms, FuelTech O2 and EGT Controllers offer comprehensive engine management solutions.
