Thread: Flex Fuel % on 3.5" TSLCD

  1. #1

    Default Flex Fuel % on 3.5" TSLCD

    Hello. I have my 553-108 touchscreen hooked up and working pretty good with my Holley HP ECU. I just assumed before I purchased it, that I'd be able to setup a custom gauge to display flex fuel percentage. I have the flex fuel sensor installed & working. I can setup a gauge on the Holley laptop and I can also read the sensor on the touchscreen by going to input 1-5 screen. But I want to incorporate it into one of the main custom screens, so I can have other items displayed like, WBO2, TPS, etc. When I go go setup a custom screen, it only allows me to select the predefined Holley internal variables. It doesn't seem to allow me to select one of the four custom inputs. Any ideas? Am I looking in the wrong spot? Thanks, Tim

    Well, you can't do it. To put it bluntly, that's really stupid. Man I really get frustrated with the Holley EFI software sometimes. I never even looked before I purchased it if it could do it, because it seems so logical that it should. It's like buying a toaster and having to ensure it makes toast!

    Yes, you can. If you look around and go through “Inputs” on the screen, you’ll see “Inputs 1-5” & “Inputs 6-10”. As long as your ethanol % input is in one of those spots, it’ll show up.

    OK, yes you can display it on the screen using the input section, but you can't display it on one of the custom dashes along with other things. For example, I'd like A/F Ratio, Fuel Pressure, Knock, and Flex Fuel all on the same screen. Can't do that.

    Nope. Can’t do that.
