Thread: Terminator X Max LS1 bogging when revving.

  1. #1

    Default Terminator X Max LS1 bogging when revving.

    Hi. I've installed a Terminator X Max on my LS1/4L60E Buick Century. It idles fine, slow ramp ups are good, but revving causes the engine to bog & sometimes dies. If it dies it won't start up again. AFR is at 14.5 idle & 14.7 high RPM (set it to 14.7 to try a leaner mix). New fuel pump, regulator, coil packs, spark plugs, wires & TPS. It had a similar problem on stock ECU, but only in Drive. After installing the harness & ECU it happens even in park.

    Pay special attention to the center paragraph in blue print:

    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).

    Sorry, my bad. English isn't my first language. I'll try doing that today and see if it fixes it. Also for knock sensor settings, copying the settings from a Holley EFI Global File with the same setup to the Terminator X software is okay, right?

    In that case, no problem. I'll continue editing your posts. Forum members appreciate this, especially when English isn't their native language.

    Yes, if your knock sensors are the same as what's in the Global File.

    After fiddling with the tune for a while, I got it work flawlessly now. Base tune & Acceleration Enrichment were way too rich for it & reduced the rev limiter to 6400 instead of 6800. As for knock sensors, the Global File didn't have them setup, so I'm setting them up using the tutorial on the forum. Thanks for the help Danny.
