New Injector Question...

[PDRacing]

After replacing injectors, where do i input injector flow info at? Do I plug that in injector flow/kpa chart?

If you bought injectors with data they tell you what tables you need to change.

Injector flow rate vs pressure, flow rate vs volts, maybe an offset settings or two.

These are FAST units and no data was sent...the only thing I know about these is they are 57 lb/hr @ stock pressure which i believe is 53-55 fixed psi..

Find out who makes the Fast branded injectors and get the data from them?
Here is something that I found from 2015 on here. I don't see the offset and min pulse
MAP (kPa) 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80
Injector Flow (g/sec) 7.182 7.2416190562 7.3007512702 7.3594083773 7.4176016487 7.4753419168 7.5326395989 7.5895047192 7.6459469287 7.7019755252 7.7575994706 7.8128274076 7.8676676757 7.9221283258 7.9762171337 8.0299416137 8.0833090299
If your fuel pressure is 43.5 psi then put these figures into INJECTOR FLOW RATE vs KPA table. 7.18 being 0 kpa and 8.08 being 80 kpa
lse.

ok ill look into this... asap!!!

Now that I look back at your post, I don't think what I copied is going to help since you have 55 psi fuel pressure. Looks like this is for 43#

[Lakegoat]

I found a couple of posts that say that the fast is made by Bosch. Maybe try somebody that sells Bosch?

[PDRacing]

ok ya i thought the same thing when i saw the fuel psi you posted. i will dig into and see if i can get some info on bosch injectors. thanks for the info on this Lakegoat....

Did you ever find data for these injectors? I have the 57 lb ones as well and am wondering if the injectors are possibly hurting my power level due to them not having the completely correct data.
