Ecometer finally dialed in

Stupid question:

What is DFCO? And what/how/why do you "dial in" the ecometer?

Deceleration Fuel Cut Off


The ECU actually stops sending fuel at some moments, when it can do
so, and not make the car buck.

This is what Partial Zero Emissions Vehicle means.

saves gas when otherwise you'd have injectors open at idle position.

dial-in

means fill the gas tank to the first gas nozzle shutoff, and then keep
gassing up at the very same pump and same nozzle for a few weeks, and stop at the very first shutoff. do this a few times and you can calibrate the ecometer so it knows exactly how much gas is burned compared to how much it thinks is burned.

the computer estimates gas use by injector timing, revs, and other factors but you need to tell it how
much gas you really put in to make the tank full....then the meter will adjust by a percentage to give
the most accurate readings day to day

To add to the last post. The Ecometer can be fine tuned by changing the percentage. It comes set at 100%, you can raise or lower the percentage to get it to match the pump calculations.


The only stupid question is the one not asked.
