Thread: Holley 3.5" TSLCD Question

    Default Holley 3.5" TSLCD Question

    What's the difference between the 553-115 and the 553-108? Is it the same screen and the more expensive one comes with wiring parts? I want to add the small screen to my HP EFI installation. The extra wiring things serves no purpose to me.

    Look at the Holley product webpages. The Holley 553-115 is a Sniper EFI service replacement, and the Holley 553-108 is for the Terminator, HP & Dominator EFI systems.

    The question is are the screens the same part just with different connectors? Both are CAN Bus. The descriptions of what each touchscreen can do looks the same.

    No, they have different device firmware versions. It's only $10 difference for the correct touchscreen unit.
