hi there guys,

doing a massflo (carb style) efi conversion for a mate who wants to re use his old AU2 injectors,

Bosch No 0280155903

I believe these arent a true 24lb at 43 psi,around 22 odd

would like to find the hi/lo slopes and breakpoint etc used in the factory tunes,

programming a moates J3 and BE to tune an american A9L/GUFB strat..

Cheers In advance

Peter..

afaik there actually only 19 or 20lb, my au3 has the moates 1/4 horse and the calibration shows the injectors as 19lb, actually I have a couple of calibrations for std 5.0, te50 and xr8 and they all have 19lb on injector slope.
if I change mine to 24lb it actually runs lean, as the injectors are actually smaller than what im telling it..
so many people say the au 2/3 injectors are 24lb but I found so much conflicting info that says otherwise...
imo, best to source true 24lb or bigger injectors...

anyway, for 24lb I set my low slope to 24lb and multiply it by 1.3 for high slope which is 31.2..
not sure how accurate the high is, but im going on the recommended info on binery editors notes under injector slopes...

someone else might have more info...
