    My EFI is running rich. I have to hold the pedal to the floor and then the scout will start after cranking and cranking. Once I get it running, it runs pretty good. I need to set up the laptop and see why. I know part of the problem is, I don;t have an 02 sensor hooked up yet. I was hoping to get this thing running well enough to get the exhaust redone, and have a bung welded in at that time.

    I do not have an aldl plug. It looks like Bill used a USB cable and wired directly to the ALDL orange and white wires. I have a ton of USB cables around here. They look like they have 4 wires when you cut off an end. What wires tie with the orange wire, and what wires tie with the white wire?


    Any help is really appreciated!

    Make sure the initial setup procedures are performed correctly.
    Check for any error codes using the SES light.

    Your usb needs to be a TTL specific cable.
    You don't use the white with black stripe, that is used to jumper to the blk/gnd wire that should be in pin A, to make it enter the diagnostic mode. That will blink the SES light and provide your error codes.
    For ALDL, which is explained in the data logging FAQ, you use the black.pin A and the org/pin E.
    If you have a standard 4 wire TTL usb, then you use the black wire to black and the white wire to the org.
    YOU must use an old win98/XP/Vista laptop for standard installation of program and drivers
    OR
    For win 7 and newer
    You must disable the wifi adapter prior to loading any software.
    Install winaldl directly to the C:/winaldl directory
    Install the 2010 version of the driver(if using a prolific chipset) or the current driver if not prolific chip.
    Make sure wifi adapter is still off, then plug in usb cable.
    Check device manager for port assigned during install.

    or
    Send me $30 for a cable and software.

    Thanks bill! I know I have error codes, because my dummy light tells me so, but I cant check because I dont have anything to plug into. All I have are a white and orange wire off the back of the ECM plug. Do I understand correctly, that if I buy the USB you provide, I just use spade terminals to tie to the Orange and White wires on the ECM? Then I just plug that into a laptop?

    I currently have Windows 10. Will your software work with this?

    When I can get this thing to start, it runs really good. I am almost there! Thanks again!

    You need to read my post again.
    Then look at the wiring FAQ for the wires that are supposed to be in the ALDL plug.
    Then read the data logging FAQ to see which to use.

    Ok, I guess I was confused. In this picture, you are not using a plug, and I thought I could get away without one? no?

    If you look close, there are 3 wires not 2.
    It's probably described in the write up also.
    You need all 3.
    Just as shown in the pic above.
    Blk, wht and org

    Yes, I see that now. I guess my question is; do I need to have an actual plug, or can I simply use spade connectors like you did here? Can I tie spade connectors into your USB cable, and forgo the actual aldl plug?

    Getting the driver to work is tricky. Just remember to turn off wifi mode and you will be good to go. I forgot once and it "updated" on me so it wouldn't work. Once you turn off wifi and revert to the correct driver you're good. I think if you have an oldie time laptop with a serial connection you can wire it right in (you'll need to make up the serial connection of course). But the USB wire is much easier and future proof.
