Hi,

I just noticed that oxygen sensor(0114-011B) voltage values are not calculated correctly. Their range should be -100 to 99.2% or 0-1.275V. Now they are showing values like 5000.

http://en.wikipedia.org/wiki/OBD-II_PIDs has formulas for calculating value.
Currently they are calculated with formula (A-128) * 100/128.

I think the formula for showing value in Volts is: A/200
Formula for showing percentage is (B-128) * 100/128 (if B==0xFF, sensor is not used in trim calc)
