    Scroll through the datalog to the problem area. Then look exactly where this happens on the Base Fuel & Timing Tables. Scrutinize:
    RPM, MAP, MAT, TPS, CTS, IAC, Target AFR, AFR Left, CL Comp, Ignition Timing, Duty Cycle, Fuel Flow, Fuel Pressure & Battery.

    Using the Holley EFI software (LINK), look at where the live cursor moves to during this occurrence, and
    manually tune that area of the Base Fuel Table (enrich or lean) & Base Timing Table (optimize ignition timing).


    I find the most helpful datalog function, is overlaying the datalog on your Global File.
    I'm in the habit of using the datalog Overlay feature every time I review a datalog.
    Click on "Datalog" (on the top Toolbar), "Activate Overlay", then "Open Data Log".
    You can literally "playback" a recorded event, and watch it as it happened on any screen.
    Minimize (shrink) the datalog window, and move it to the bottom of any Global File screen.
    Then click & scroll anywhere on the datalog, and watch it playback on your Global File (EFI software).

    So, I did record a couple datalogs. Downloaded V4 firmware, etc., on a borrowed laptop. The ECU had V4-64 and I was prompted to update to V4-101. Saved the current Global File to the SD card in the TSLCD (couldn't figure out how to save it to the PC). Updated, reloaded the Global File, and tried to download the datalogs. They got about halfway, then stopped downloading and displayed a generic error message. Am I correct in assuming I need to record new datalogs with the updated ECU?

    No, the V4 EFI software should've converted the previous version V4 datalogs.

    The datalogs would not load before the update, and after the update the ECU and laptop won't sync when plugged in. When I attempt to sync it takes a while then I get "timed out" notifications. Tried a few times over a few hours. I did save and reload the current tune after the update. The Jeep is running well and I could not replicate the symptoms even slightly on the drive home this evening even after a few fan on/off cycles. So problem solved in the short term, but now I'm itching to sync the ECU to the laptop and get my hands dirty learning and tuning...and I can't LOL. Any advice?

    Thanks for that link! I now have the TSLCD user manual. The EFI came to me in a vehicle I bought used, along with zero info about it. I've been piecing it together since.

    So far I've only gotten as far as uploading the last good tune and lowering the temps at which the fan toggles on/off by 5°F. The symptoms have vanished and it runs like a top. I've also started putting together a base tune on the laptop and looked into troubleshooting the connectivity problem I had. Have some travel coming up, so won't be dealing with this for a little while, but I'll post back up with results and questions when I do. Thanks for the help so far.
