    Blue/White wire that goes to pin A28 is the tach signal. Is this engine stock? Is it an LS2 or is an iron block? The LS1 is Gen III with 24X crank & black sensor. The LS2 is a 58X crank with grey sensor. These could change what file you want to use.

    The Base Fuel Table is just a smooth starting point for the Learn to work from, and correct from the Target A/F Ratio Table. Base Timing Table Holley has with a total timing of about 24 to 25 is safe, and shouldn't need to be touched at all, unless you want to extract all the performance from the engine one day.

    Thanks, I'll check that out. Dickens, short block is an LQ4 iron 24x crank with shaved LS3 heads & Texas Speed camshaft.

    OK, another stupid question. I have to wire my fans in. I noticed the LS1 setup had a fan section, but I didn't see where it was pinned too. Is there a separate wire for that too that I didn't notice, or do I have to assign a pin for that on the outputs? I have dual fans, but I see no need for my application to have them wired separate. So I ordered a 75 amp relay for them and will wire them together. Thanks guys!

    You will likely be making more power than that fuel table. I would copy the Base Fuel Table from the 480HP LS2 Global Folder and put that into the one you're using now. You can just click & cell. Use Control-A to select all, Control-C to copy. Then select all of the one you are using, and use Control-V to paste. Standard windows short cuts.

    There is no standard wire for fans. You have to turn it on, and then pin it to a wire your self in the Pin Map.

    Thanks Dickens. I will do that, I'm still a ways from startup but getting closer.
    Texas Speed estimated my HP around 530 on my setup, so the 480 HP fuel table definitely sounds like a better starting point.

    So everything is all wired up went smoothly. Still have some chassis wiring. But I did notice, hence my confusion under the loose wire ID, there's no mention of the blue/white wire. Only mention I can find about it, is in the link Danny provided, but it's in regards to LSx engines with front timing cover cam sensors. Mine is in rear of engine, so you can see my confusion. May want to have Holley change/add that to there directions.

    I brought up the same thing to them when I first did one, and had to call & confirm that was the correct pin for the tach. Back then, the harnesses didn't have a wire in there to use, so you had to steal an unused input or output wire.

    The "NOTE" at the end of that document (LINK) is for all LSx engines.

    OK, so messing with outputs. I have B10 setup on fan negative, no issue. I went to setup another output for a shift light. I have a single LED in my dash setup for a shift light. Problem is, when I went to configure, it won't let me choose RPM. Here's a pic, any advice? As you can see, when I do drop down to choose RPM, it's blank.
