    injector calculator spread sheet

    I'm going to give it a shot at running racetronix 42# injectors but I can't seem to find the excel spreadsheet that allows me to calculate the data based on what racetronix data is. Can anyone show me where it is? I have an excel spreadsheet for injectors but its for scaling and I'm not sure if that the one I need (ERM tuning gave it to me when I bought Ed's tuning course

    Short pulse adder, min injector pulse, offset vs volts vs vac, etc. I have a bolt on ls1. 317 heads ported and polished, long tubes, msd atomic airforce intake, return style fuel system, 90psi 340lph fuel pump, ls2 injectors, 102 tb, cai, Mild cam, built bottom end and I did a WOT pull and at 6000rpm I was at 106%duty cycle and 22ms. I have a set of 42# racetronix and was wanting to try and use them and needed to know what to input into those tables. (Short pulse adder, min injector pulse, offset vs volts vs vac,)

    You could try searching the HPT database for someone who's already done it
    I found this one that had racetronix #42 in the description so you should be able to pull the values from that tune.

    Hope it helps.
