Lost injector info

[bsaathoff73]

I need help. I can not find any info on my injectors.I tried contacting the person i got them from but no replies. I have a tune in my carand it runs, but im totally new at all this but im trying to learn.
They are bosch high emp 52lb 550 cc injectors with ev1 adapters. Part number, 0280158279.
Lt1,383, stock rails, stock intake with m122. I apologize if this thread is wrong. New guy here.
Or can i tune the injectors into the tune better or get new injectors.
I was told 52lb, then now im told 60lb but ive done no different to the motor. Kinda lost on all this.

Depends on your fuel pressure.

I have stock pressure. New walbro 255 pump. New regulator.
The guy who started tuning said 52. Guy who built my motor said 52. Fic says 60. But my 52, i cant find my papers on them and the tuner put in the wrong info after receiving the info from me.

Did you go to the website I posted? It tells you.
Flow rates:
47 LB @ 39.15 psi
550 cc/min - 3.0 BAR (43.5 psi) 52.4 lbs
594 cc/min - 3.5 BAR (50.8 psi) 56.6 lbs
635 cc/min - 4.0 BAR (58.0 psi) 60.5 lbs

So if you have a 4 bar 58 psi fuel pressure your injectors will flow 60.5 if they are "correct" not decaps or China garbage.

It sounds like but search didn't show up.. that these are the old GT500 injectors? Sorta orange band on them?

I might have data that I converted from Ford on them.

[bsaathoff73]

Completely black with green oring n black oring

[bsaathoff73]

Hp tuners sure makes one feel dumb as a rock

[Alvin]

In that case you will be better off going to a injector with known injector data

Myself or Alvin can convert this over to GM format for you. Running 43.5 factory pressure?

[bsaathoff73]

Yes im stock pressure. Im going to order some 60s down the road but it'll be a month or 2. Car has been sitting for over a year because i keep getting burnt so im trying to learn this hp tuners stuff so i can drive my car. I had injector info one time but the guy put in the wrong info from what i was told.
I kinda got my car going. It starts at least now and dont bang n pop like it did. It also seemed to loose half the motor for some reason. Was told whole tune was a flop. So im trying to learn all this. i dont know how to add the tune file he sent or the one in now on here. Step by step ill figure it out. Kinda computer dumb here. Totally hp tuners dumb
Thank you also

It'll take me about 2 hours to do the conversion. If you're switching injectors then I won't bother. Thing is I can get the data for you and it'll be so good you won't need 60's. The only problem is the wide spray angle of those injectors is designed for 2 valves per port. Sometimes makes for transients issues like a brief rich tip-in. No big deal. I run similar wide spray injectors. Lmk.

[bsaathoff73]

That would be great if i can just use these ones i have. Was going to switch because i just cant find info. If you can figure it out for me that would be great!! Then i can just use these ones.
I wont be on for 3 days. I work 12 hour shifts a hour away from home. Id appriciate any help i can get and just whenever you have time.

[SiriusC1024]

Awesome that'll give me some time. I'll get it to you by the time you're back.

[bsaathoff73]
