WB won't read Methanol

[Richard Wakeling]

Hi Gar,
    WB is home brew, modified diy-wb, complete 'instrument/interface/datalogger'.
Calibration checked against latest Motec PLM for petrol and was spot on. Of course I
expected some A/F change using methanol but not 17:1 and 18:1.  Maybe the high water
vapour (H20  2 parts oxygen) is upsetting the NTK sensor. I am still scratching my
head.

Cheers Richard
