Effect of Calculated Load Value on fuel consumption
hi,
Fuel consumption of my elantra is very high.
When i checked the injector pulse width with an oscilloscope, it shows
values around 4 - 6.5 ms when engine is idle. Since these values are
too high, i did a scan of the engine parameters while its is idling. I
did a similar scan for a different elantra car as well.
When these values were compared, all parameter values had similar
values except the Calculate Load Value (CLV), which is 4-6% in my car
and around 45-55% for the other car. (this other car does not have any
problem).
What would cause CLV to drop this much?
Could this difference explain the high fuel consumption?
thanks

Less load equals less fuel-- so lower load values won't cause
excessive fuel consumption.
Additionally, 50% load idling in neutral or park is way too high. The
other car has the problem with this value, not yours.
