    Use blindsquirrels "returnless" .hpt
    If you had a manifold referenced you would use the other.

    Will this data work for the DELPHI 12613412 also?

    No, because they are different injectors with different characteristics.

    Thank you for the info. It will make life a little easier when adding these injectors in having a good base lane to start from. Just picked up these injectors (12613412) for a killer deal. Going to send them out to have them clean then put them in.

    Just for people who come later...

    Source for 12609749 data:
    2010 Silverado 1500 E38 L92 1GCSCSE24AZ225217 (OS 12636005)(12609749).hpt
    Source for 12613412 data:
    2010 Yukon E38 L96 1GKZKREG0AR189018 (OS 12636005)(12613412).hpt

    Neither of these work with the conversion spreadsheet, they were converted by copy/paste/interpolate. (https://forum.hptuners.com/showthread.php?98228)

    Open both files (in separate editor windows, since format differences between different PCMs don't always show up right when using the compare feature) and see if they have all the same tables & covering the same ranges. I could just tell you 'yes', but then you wouldn't learn how to answer stuff like that on your own.

    How would you set it up for a vacuum referenced return style on a 411? I see the format is the same but the flow rate is steady in the P59 and sloped in the 411. Or do I just get rid of the vacuum reference?

    Compare the files I posted up above to see the differences needed for the different regulator types. Referenced-style uses the 0 kPa VAC column across the entire table for both Flow Rate & Offset vs Volts vs VAC.

    edit: Files you're looking at are different not because one is P01 & other is P59, they're different because one has a vacuum-referenced regulator and one is 'returnless' (really just shorthand for 'referenced to atmosphere instead of manifold pressure').
