    LSA with LS7 Card Style MAF And 102mm Tube - Anyone have an HPT file?

    Hi All,

    I have got my LS7 MAF + 100mm tube working well and now need to look at scaling it to the stock tuned 2013 CTSV E67 ECM.
    (MAF CARD - GM Part#23256991)

    Has anyone got a similar setup that has been tuned and finalized and can share an HPT file, so I can get a base MAF scale extracted and installed.

    I have currently installed a MAF scale from a 2013 Camaro Z28 (LS7 engine) which is felling better but is still not quite right. (Fuel trims are still adjusting a little too much)


    Thanks in advance
    Craig

    Create the chart, collect the error data, apply the error % to your file. No one else's file will be correct for your particular unique combination of parts and vehicle condition. Just tune it. This is what 'tuning' is.

    The type of MAF doesn't matter as much as the tube it's installed in.. Bends before/after, size of tubing, clocking, etc.. all matter. Make sure IAT1 is calibrated. Off the top of my head I don't know if the LSA maf and LS7 card style maf uses the same IAT fuction.

    Cheers, I have calibrated IAT1 from a known source (E67 to LS7 MAF table)
