Thread: 127# Injectors

    127# Injectors

    Im tuning a 2010 Corvette w/a F1 on E85. It has a return fuel system now. Set at 62psi. It has 127# injectors. Can I just put the whole IFR table to 127? Or should I enter the correct values up to the 127# cutoff and then just have 127 thereafter? Thanks!

    if they are 127lb injectors at 62 psi, then that's what you should put across the table. be sure to do the same to the volt offset table too.

    The injectors actually flow 127 at 58 psi. When I first got car running I put the whole IFR table to 127 and fuel pressure at 62. Then I was looking at the info on the injectors and saw that it was at 58 psi so I will adjust the pressure today to 58psi.
    Why does the tune need to be scaled?

    You're telling me that in the IFR column, it accepts a value of 127. Another words the tables limit is not 63.5 lb/hr?
