Hello.
I'am looking at the Tuner Cat software.

I'am a bit confused here and mabey you guys could help me out.

From the "sticky"

"- injectors. Want to run high FP, or bigger injectors, no problem. All you do is figure out how much you're changing the relative injector size (for example going to 22s from 19s, you just multiply the injectoor constant by 22/19) or if you're changing pressure, the number you mutiply with is given by this formula squareroot{(new psi^2)/(old psi)^2}"

When i look at a bin for my car in Tuner Cat, it says 22.1 #HR.
The stock flow in my Chevy corvette 1990 is 22 if i've got it right.

Now i'am planning to purchase Ford #24 SVO injectors.

So when i'am about to change my chips flowrate constant i supose i will do like this: ( Just wanna be 100% Sure dudes)
22.1*(24/22.1)=24

I'am sorry bothering you with my stupid question but i don't wanna go messing up my fuel suply and destroy my engine

 

Simple math tells you that multiplying something by a fraction that has the same number as the denominator gives you a cancelling affect. In other words, just put in the new inj. flow rate and don't do any math. However, the ford inj's are flow rated at 38psi and gm ones are rated 43psi (3 bar). So, you would have to do the math for that and then plug in that number. I believe 24 svo's end up being 26# inj's with 43psi.

 

Aha. Tanks dude.

I'am also investing in an adjustable fuel pressure regulator, so
i will set the proper pressure for the injectors and changing the ECM. I guess that will do it?
