From SD card to results

  1. Pull your files off the SD card

    Take the SD card out of your Sniper handheld and plug it into your computer. Look for:

    • Datalogs Saved Datalogs\
    • Configs HOLLEY\FW0200\Saved GCF\

    The drive letter varies, so check whichever drive the card mounts as.

  2. Add a datalog and your config

    Datalogs are .dlz or .dl files. Your global config is a .sniper file, or .terx on Terminator X.

    Several logs from different conditions, like a cold start, highway cruise and idle, give a fuller picture.

  3. Read your results

    Fuel trims, timing, IAC position, coolant temp, battery voltage and more are checked automatically, with results in seconds.
