Thread: Can't datalog.

  1. #1

    Default Can't datalog.

    As soon as the engine starts, the datalog stops and the Holley app stops responding all together. Dead. The only data in the datalog file is perhaps two seconds after the engine lights off. It's not power...we even powered the ECU from a separate supply totally divorced from the truck. The ECU on the other hand, is obviously still running, because the engine is still running. What the heck? I'm used to the robust C950 interface, and this nonsense really has me puzzled.

    I have no idea what's wrong. You may have to post a video of how you're trying to datalog.

    I will. The message bar above the Holley app screen gets the "stopped responding" Windows message. There is also a cryptic little hint bottom right of the Holley screen, "Dirty". I'll try to track down what that means.

    I know I've got some real challenges ahead. 239 ci flathead V-8 with MPFI and a Powerdyne supercharger. 19# injectors and throttle body from a 4.6L Ford. So the base tune I loaded from the limited library of options is probably waaayyyy off to begin with. Longtime C950 user, this HP EFI stuff is going to take some getting used to.

    "Dirty" appears when you have unsaved changes to an existing saved file. Do you have your USB cable near any high voltage sources?

    Interesting, thanks. And no, the USB cable runs from the ECU to my laptop sitting on the pass seat. We even disconnected the power supply from the laptop and moved that away to see if it made a difference. By "saved file", are you referring to a datalog file?

    He means a Global File (engine file).

    OK, I might be onto the problem. I tried a couple more times to start the engine, while the Holley laptop app was all synced up & reading data. Holley app immediately crashed both times. I then tried to start the Holley EFI app and connect after the engine was already running. Couldn't. The USB connection was totally gone, EFI software could not find the ECU.

    Fiberglass body. ECU mounted on inside of firewall & Blaster ignition coil mounted on outside of same real estate. I think that as soon as she fires off, the ignition noise is corrupting the USB connection. Back with more info after I relocate the coil.

    Also, ensure the EFI software is set to run as an "Administrator" (right click for Properties/Advanced). Set it and forget it.

    OK, I'll check that. But would that have anything to do with the app halting as soon as engine lights off? I'm looking at good data from all sensors before I crank her.

    Moving the coil to far end of the engine compartment had no effect.

    On the positive side, I just let it run and it went into closed loop mode, and pretty quickly started running pretty darned sweet! I still have to splice the correct connector to run the square Weather-Pack connector GMC IAC stepper though, so she's not idling correctly yet. I sure wish I could watch all the data though. I'm going to try a different laptop next, but the one I'm using is a Toughbook and seldom ever see issues with that.

    I use a Panasonic Toughbook CF-52 laptop that had Windows XP Professional (now has Windows 7 Professional). It's the best laptop computer I've ever used!
