Onboard computer mpg - how is it calculated?
When I zero the onboard memory for mpg the readout is quite responsive to driving
conditions for many miles. Eventually, though, it doesn't vary nearly as much as driving
conditions change. Just interested, what is the formula or algorithm the computer uses to
calculate the mpg?
It is average based. The computer compairs the amount of fuel it injects to the run time since the last reset.
