Round WBO2 EGT calibration problem

[kimmoz28]

I have Vems wideband but i have problems with calibration. Wideband show 18.9 in free air so its have to calibrate, but WB02 calibration button is "grey" in vemstune and cant press it. Connection with vemstune and wideband working and i can update firmware.

You don´t need to calibrate the VEMS wideband gauge for the sensor, it reads the sensors resistor to do so automatically.

If the sensor is used then it will never free air calibrate properly as it now contains unburnt fuel which will skew the "free-air" reading
