  • Carputer stalls when accelerate the car

    When i put the pedal to the metal my carputer stalls for some seconds, sounds is stuttering etc. When i stop accelerating everything goes back to normal.
    Perhaps it has something to do with higher voltage during accelerate (because of the engine power), but i dont have a clue, maybe its a common problem.

    My setup is an Opus 150W, Via Epia M10000, 2.5" 12 GB Disk, and some other stuff of what i think is not really important for this issue.

    Thanks for all the help/suggestions

    The Opus should compensate for increased voltage. It most likely has something to do with the g forces, perhaps causing your disk to error on reads.

    Try reorienting your disk drive and see if you have the same problem.

      Thats a good thought, i'll try it

        Try checking ALL connections over again... Could be a loose connection that is disconnecting when accelerating...

            If a Corolla that have enought torque/horse power to cause a dish error to "stall/freeze" the PC, the HD is probably on it way out. Does the PC stall/freeze when you go over speed pump? Well if you have a Turbo corolla (Levin?), and that a different thing.

              It will be a conection well before it is a disk. It could be power or motion related. Check all power and data connections as well as cards/RAM

                  C'mon now, really? What do normal street cars pull when accelerating? It can't be more than 1G, probably something like 0.5G to 0.75G max. If this is his problem, he can generate more force by braking.

                    I mean that if the hard drive is defective, the acceleration may be affecting it, however low it may be.

                    I just can't see how an electrical surge would cause the computer to skip, but then revert to normal when the surge stops. The computer either ought to function or it ought to freeze.

                    But skip? Then return to normal because of increased voltage? That seems far fetched.

                        Actually I just re-read what I wrote and it makes no sense that brake would generate more force. The tires are the limiting factor, not the engine versus the brakes stopping power.

                          True but if Drives do not skip during a car crash why would aggressive driving at a start/stop matter.

                          They work right through the car crash... I have done it.

                          The issue will be a loose connection or power related.

                            it's true though, that almost every vehicle on the planet can stop MUCH faster than it can accelerate, so braking G force will be much more than acceleration G force, and is usually applied MUCH more abruptly. top fuel dragsters excluded.

                            a porsche having a hard time hitting over a G on the skidpad? well, first off, to get up to and maintain that 1g you can't be abrupt about anything. abrupt G forces is what causes hardware failure, not smoothly applied ones. and if my miata can hit a lateral G on street tires, then a porsche should be getting at least 1.25 lateral Gs. unless it's like a 1958 porsche... heh

                            back on topic, i think he's definitely looking at a loose connection somewhere. and yes, it's entirely possible for low-grade power transients to cause a machine to stutter but recover once the transient is gone. i used to see it surprisingly often at a former job. once we installed UPSs with power filters, the stuttering went away completely. all depends on the machine itself. some hardware can tolerate it better than others.

                              I don't think it's the G force that causes the problem.

                              I am having the same issue on my motorcycle computer. When ever I hit the gas the MII 1000 sometimes reboots or the music just skips a bit.

                              I hooked up a volt meter and found that when I hit the gas my battery is getting 13.1 volts but for some reason every once and a while the volt meter drops down to 0 volts. Which is what I think causes the skipping/reboots.

                              Could this be a bad engine ground?
