So why does the trip computer say 38.4 mpg?? It was reset when I last filled up.
As the computers are not reliable. Mine is fairly OK, but I have heard about computers showing very different values from reality.
BTW, when I unplugged the MAF on my GTA, I noticed that the car can’t display actual and average consumption and range. Plugged it back and everything worked ok. So I think the body computer uses MAF data to calculate the consumption and not the data about the length of injector opening. What is a little stupid, because even with MAF disconnected the ECU should know how much fuel it’s using. So the consumption data on body computer depends probably more on the precision of your MAF (what is less precise with age/wear) than on the real fuel usage.
