  • Requests for Custom Standalone Harness Length

    Requests for Custom Standalone Harness Length

    We often get the request to provide a custom/extended length harness between the engine connections and the control module connections. This is typically requested to accommodate remote mounting of the control modules.
    Unfortunately, we do not provide this service for the following reasons:

    • This would require a significant amount of labor
    • Due to the large number of solder joints (80+) this introduces many possibilities for failure
    • Increased wire lengths affect the resistance of circuits and may cause interference to critical signals (cam, crank, injectors, etc).

    If you would like to modify the harness yourself, be aware that technical support will only be provided prior to making any modifications to the standalone harness, so it’s highly recommended to run test the harness and engine before making any modifications in case there are any issues with your engine that you may need support with.

  • LML DSP-5 Custom Tuning

    LML DSP-5 Custom Tuning

    LML DSP-5, actually SOTF

    Switch on the fly (SOTF) tuning on the LML Duramax platform does not provide 5 individual maps like previous year duramax ECM’s. It simply utilizes the fuel rail temperature to limit the total fuel quantity (MM3). It is the electronic equivalent of putting 4 different sized wood blocks under your accelerator pedal.

    Whether tuned with EFILive or EZLYNK, your ECM will only have one calibration. Therefore we don’t offer the SOTF (DSP-5) option for LML since we don’t see the added value and prefer to keep the fuel rail temp functioning as the OEM intended.
