    Question Please give me your opinion on my LS3 injectors to LS1 ECM tables

    Hello, just got my HPtuner's software and I enjoy being able to see what the car does and all. I have a 72 Nova with an LS swap. I would like to know if my copy paste on the injector tables is correct. I assume there are only 4 tables that are needed to be copied, Flow Rate vs KPA, Offset vs Volts vs VAC, Short Pulse Adder and MIN Injector Pulse.

    Here are the specs of the swap:
    • Block is a Gen IV 6.0
    • L92 823 heads
    • LS3 Intake
    • LS3 Injectors
    • LS3 MAP sensor
    • BTR LS3 Cam STG II
    • LS2/3 Knock Sensors
    • 4L65e with 2800 stall


    It is all controlled with a LS1 ECM and BP Automotive harness. I got the LS7 Injector tables from here, http://www.hptuners.com/forum/showth...or-LS1-PCM#top

    I also found this thread (from 2010 though), http://www.hptuners.com/forum/showth...-To-LS1-Format, has the spreadsheet but the numbers are slightly different. So I opted to use the DSteck file.

    Any opinions will greatly appreciated. Thank you for your time.
