=ABS(((V2-V1)/(T2-T1))*1000)Where ABS() is the absolute value function, T2 is the time from the current row you're working in, T1 is the time from the row before the one you're working in, V2 is the MAFv from the row you're working in, and V1 is the MAFv from the prior row. What you've just done is to calculate the rate of change of MAFv in Volts per second. The higher the rate of change, the more likely the data is to be unreliable.
What is meant by that? My log has one column of time and one row of mafv, but you are specifying for two.
2.4 V2 V1
2.7 V2 V1
3.0 V2 V1
... working here, he is calling this (the 2.8 cell in this row) V2
... and the [3.0] from above, V1
at least, that's how I read it..
WAIT.. you saying youve got one COLUMN
, and one ROW
