    So this is actually an Avenger that I bought used, but I'll be using a laptop, so in essence it's HP. Is the Innovate LC-1 that was in play with the Commander 950 not needed with the Avenger/HP? I see the wideband connector is entirely different on the HP as compared to the Commander 950. What style of wideband O2 sensor is used on the HP? The brand new one I bought for the Commander 950 (along with extension) is money wasted I assume? I have no idea if the used sensor with the HP is any good.

      You need to read the Holley EFI instruction manual. The Holley EFI system must use the Holley EFI WBO2 sensor. It's a proprietary wideband O2 sensor (LINK), specifically made & calibrated for Holley EFI. However, Holley's 534-199 4' long WBO2 extension harness is compatible.

      Open the Holley EFI software "Help" Contents ("Help" drop down menu), and read "Step-By-Step Beginners Tuning".
      Ensure the EFI software is set to run as an "Administrator" (right click for Properties/Advanced). Set it and forget it.
