Today i experienced a weird issue.

Parts that are involved:

Kit 1:

Kit 2:

Round (serialnr?) which also reads fine with its WBO2 sensor B.


so Round is now connected to WBO2 sensor A.
  • what is the rcal resistance of sensor-A ? (between pin2 and pin6)
  • round with sensor-A will not read richer than 0.92
  • did you see this on the round (maybe reading something different or using a multiplier?) or on the connected notebook in megatune / vemstune ?

Any help appriciated.
