WBO2 sensor information
- Bosch LSU4 sensor
Relevant WBO2 parameters:
wbo2_warmup_ramp=FF it seems safe to use FF with proper LSU4 mounting, slightly faster rampup than A0
wbo2_abs_limit=E8 Note that 2A is not enough! A value of 224 .. 240 allows proper heating, eg. 224 with 13V supply means max sqrt( 13 * 13 * 224 / 256)=12.16V RMS voltage
Previous problems to learn from: 12SEP2007
My O2% value wouldn't read over 16.0%, not even with wbo2_calibation =0xFF. The problem was that for some reason wbo2_abs_limit was set to 0x00, preventing the sensor from heating properly. Once increased it was possible again to correctly calibrate the sensor in free air with wbo2_calibration parameter.
