Switching to Genboard on my Golf racer before next season, because K-Jet isn't cutting it. Later on I will be doing forced induction, so I need room for change.

WBO2 question:
All wiring is correct, I have double checked. wbo2_pump_pw (0x63) is calibrated correctly, voltage is -0.03V. Measured Rcal at 127 ohms, so wbo2_calibration is set to 0xB0. Attached sensor to do free air calibration, command mde02, sensor heat comes up to maximum (0xE4) and O2% appears on LCD mlp07. As soon as heat is maxed, drops to 0x00, pauses then comes up to a reasonable level gradually. As soon as O2% appears on screen, value changes VERY rapidly from 20.9x% to 11.xx% to 17.xx% to 19.xx%, in no particular order. Ri stays between 0x90 and 0xAD. Any ideas what is going on here? All of this is without engine running.

My Genboard and LCD display:
Intake Air Temperature Sensor
Using Bosch air temp sensor, part number 0 280 130 085. Sensor comes from a VW 1.8t 20 valve, small port head.
Values in EasyTherm are:
50F=4800ohm
82F=1900ohm
208F=230ohm
Still have to test these values to be certain but thats what I have now. I believe these are +/-2F of actual temp.
Note about Megatune: When tuning sensors it is not necessary to recompile and upload firmware each time. Simply update the .inc files in the Megatune directory and watch values change in Megatune. Recompile and upload firmware when values are correct.
