Thread: Injector Off Time

  1. #1

    Default Injector Off Time

    I usually use the Holley 120 injectors, the drop down fills in the off times. Trying to save money (remember that one) I picked up some used ones. The company Hi Performance Injectors sent some info, looks like they just use whole numbets, like 8-20, as opposed to Holley's. So I have the info for 8, 12, 16, 20. How would I fill in between those numbers? Thanks.

    Thanks. I tried putting in the first number for 8 vs, then zeroed out the rest, then did the fill row, but wasn't sure how accurate that made it. Holley uses like 8.8, 9.6, etc.

    Look at the Injector Off Time in graph form and smooth the curve.

    That's pretty cool. I run the V4, but have the V5 on the desktop, so I see the graph. Maybe one day I'll switch to the V5, but I tend to leave stuff alone if they work, LOL.
