    Understanding Injector Flow in TunerPro

    Hey guys, I am trying to understand where I need to look in TunerPro to understand the current flow rate of my injectors? New to tuning and there is a million things to look at in there. So far I have been having someone else do all of my tuning on my truck.
    I will be installing the EBL system on my truck in the spring and will switch to E85 or meth injection for a safety factor on my 1994 blown 5.7 truck.

    After doing some calculations it looks like I can make my 80lbs injectors work at 30 psi; considering a 40% increase in fuel requirements.

    Primary reason for E85 or meth is I have had detonation in cylinder 7. I will be reducing the boost a little and improving my W/A innercooler. First goal is to solve the problem of detonation and not just bandaid it with E85 or meth, but I would like to add an additional safety factor and the more I read on E85 it has many benefits.

    If the 1994 Chevy truck has a 16197427 PCM which is $0D?

    Under fuel in data log:
    Injector Base Pulse Width = Milliseconds
    Injector Flow = Lbs/Hr
    Injector Duty Cycle = Percent

    1990 Chevy Suburban 5.7L Auto ECM 1227747 $42!
    1998 Chevy Silverado 5.7L Vortec 0411 Swap to RoadRunner!
