Curious what you guys are using for injector info if using the custom window
and non Holley injectors. I usually use the Holleys because auto populates
the info. But this time I used some injectors I had, they were cleaned and flowed,
76 @ 43 PSI. But I don't have voltage values. I think that's why I am having
some problems-I just picked something from the screen that was close and
high imp. I think these are Bosch.
All this seems above my pay grade, after spending hours on a trans and getting nowhere, this
truck build has gotten the best of me like never before. I might just order Holleys injs. then I know
it will have the correct #'s. This saving me money is costing me a fortune, lol.
Their on the truck, so hard to see anything-but on the bag from Eric Derr, He wrote Bosch
280-158-051, 76.5 @ 43.5 psi, 91.5 @ 58 PSI
I had found this earlier, but nothing that matched mine https://documents.holley.com/techlib...owdatarev2.pdf
Its beer time and I am buying.
i think those are stock ls7 injectors I have used them before and unmodified they flowed like 42lbs at 4 bar
once they are decapped i'm sure they could flow 80+ lb/hr but i've had a hell of a time getting good data with decaps...the latency increases in a somewhat unpredictable fashion.
They were flowed at 76.5 @ 43.5 PSI, your right the # he wrote down shows a stock inj., so
not sure what they really are-I have to go off the actual flow #'s, so thats what I inputted on
the Holley setup screen. I picked the Bosch 160's off the drop down menu to fil in the data
fields. These are the short injs., If i find a higher flowing short inj. with the data sheet prob
buy them. Fighting an off idle "shake" now, like a fouled plug, but plugs good, comp. is good,
kind of driving me crazy.
you're ahead of me in the curve using the holley stuff but with HP tuners i'd decrease transient fueling milligrams to like .020
and maybe shift the voltage offsets one way or another 10 % at a time and seeing if the idle improved.
they problem with moving the whole voltage offset table like that is it's not actually modeling the change in latency....it's not a uniform change when you decap an injector...it skews the curve into a whole different shape.
there are lots of people going fast with decaps and i'm just not one of them. I can't get reliable enough results to meet what I think is a minimum quality requirement. I know some guys on sloppy have spent a lot of time to using trial and error to get that offset voltage right, but they don't seem to wanna cough it up!

Those are what Fic and id call 80lb 850cc. Use id’s data.
I dont know how to get that info, I tried looking it up, but my computer skills are on a par
with my welding skills-if you could post that info for me i can send a beer, lol.
it should be in the injector data dropdown under engine parameters.
it's the tabel that looks like so:
BTW the pictured data are for some seimens deka 80's we are running in a friend's truck right now and the data seems solid. The AFR learn works well and all that.
OK, I downloaded the latest version to the desktop, and it is in that newer drop down. I don't like
to do upgrades with the lap top, I tend to really mess things up and loose everything, lol.
haha i'm helping a guy with HP tuners and his file can't be opened with my v3.36 so I have to download v4.4.whatever they're on now...look at it, maybe fix a few things, send the file back and then uninstall HPT entirely and reinstall 3.36 to get all my configs and stuff working again
computers are incredible tools, but they just don't come easy for me
