Hey guys, installed these Holley 522-428 42lb @ 43 psi injectors and used the excel sheet to figure out the lbs/hr at 58 psi,
after I entered these numbers the car hardly ran, went off the wideband lean, had to add around 50% fuel on the VE table to get it in the
ball park, trying to tune the VE table like this is a night mare with VE numbers up in the 125ish range in the part throttle areas and in
the 150+ range under WOT and the WOT is still stupid lean on the wideband.
its not as lean and gets a little better in the part throttle areas when I plug in smaller numbers in the IFR table.
I know I need different data for these injectors other then just the IFR table.
I played with the short pulse adder, offset vs kpa vs volts table,
min injector pulse, etc. needless to say I raped the tune slowly bringing the numbers up and down and still just cant get
the VE table to act like it should.
I even tried injector data from various different 42 lbs injectors and nothing seems to get it so I have nice control over the VE table.
I contacted Holley and there data seems to only be fit for there efi stuff and is way out to lunch for hp tuners.
does anyone know where I can find injector data for these holleys in HP tuners?
ive search for hours with no hp tuner info on these injectors.
