Fast xfi 2.0 O2 sensor setup

Mike Graham · 05-19-2024, 06:10 PM

Anyone with any experience with the Fast xfi 2.0? The oxygen sensor always reads 15.94 on the gauge panel and the monitor. I have replaced the sensor and checked the harness for damage. I don't see any calibration procedure in the manual. Any help would be appreciated.

If the sensor is in the collector it will show 15.94 much if not all the time the engine isn’t under a load.

Hi Mike - make sure you select the right sensor type in System Configuration. There's 2 options to choose from (L1H1 and LHA) and will provide a different reading if the incorrect version is selected.
