What's in it
The Calibration group holds a fixed set of tables that convert sensor signals into the values ESP shows you. They tell the Elite how to turn a sensor's voltage into a real reading, such as a temperature or pressure. You can open and edit them with the same tools as any other table (see modifying tuning tables).
When to change one
Only when you've fitted a different sensor from the one the calibration was made for. If the sensor matches, the calibration is already right, and changing it just makes the ECU read wrong. A wrong temperature or pressure reading then flows into every fuel and ignition correction that uses it.
- Get the replacement sensor's data (voltage or resistance against temperature or pressure) before you start.
- Check the result with a known reference, like a good thermometer or gauge.
- Save a copy of the map first, so you can go back.
