    Post Car PC, Power and gas question

    I wonder if installing a car pc will make much different in gas consumsion. Before i install a car pc on my RAV4 I can make about 320miles on a full tank (high way) after installed a car pc , i only get about 260miles on a full tank. Did any one have the same problem?
    I am not driving any long trip for now. so I didn't test it again with the carpc off.

    That would be strange.
    What other things changed? Payload, Wind speed and direction, Day/night?

    I would bet the PC draws less power than the headlights.

    If you have daytime running lights, you might want to consider switching them out with even generic LED drop-in replacements. That saves almost 4 amps right there so it's just about the same as before the PC, if you look at it that way.

    Tach

    Does your car have a tachometer?
    If so do you see a difference in idle rpms when the pc is switched on?

    My carpc draws less than my headlights so I never considered the fuel economy of it.

    I don't remember other thing that is different. I did need to start the car and set up my pc for the trip but it wouldn't take more then 10 min, and I did make two more stop to the bath room..... If i have the chance to take the trip again. I will try to use the carpc for going and no carpc for comming back.

    rpm wont show a thing on modern cars, the ECU will see the rpm drop and give it more gas to maintain the rpm.

    cars first had that about 20 years ago.

    Ain't no way that a PC will make a 60 miles per tank difference. (10 PC's wouldn't do that) You have other issues, tire pressure, tune up, etc.
