    Looking for Pentastar 3.6 Sprintex SPS stage 2 Bosch 52lb Injector Data

    Was wondering if anyone would kindly be able to share the injector characterization data for the Bosch 0280158187, 52lb injectors that I believe are supplied in the Sprintex SPS stage 2 kits?
    Chasing Inj PW/Fuel mass and Inj PW Offset etc.

    Thanks!

    I am chasing data for the same injector, to suit E40 Gen IV ECU,

    Wish I understood the data more.

    Same here, I have a basic setup but in N/A I'm running around 10.5AFR at 7000 rpm. I want to drop the top end down a little bit to 11.5's (granted I'm running E80)

    Can't confirm the data but with a bit of trial and error I settled on these values. Seem to be stable and give reasonable VE numbers.
