SRT Stage 2 injector Opening time?

[zeeboid]

Anyone know this? My google-fu is not finding it.

[CASPERAMC]

not sure exactly, but most people just put i 1ms for whatever they have

[zeeboid]

ah, thats what I have them set to right now, but i'm not getting as smooth of a AFR durring Idle as I would like after installing the injectors and a 59psi fuel regulator. it kind of jumps around from 14-15.5

[boost junkie]

Idle won't be perfect with batch fire and lower PW's. It might be a little better with MS2 though because you can use semi-sequential.

[zeeboid]

ah ha.

that makes purrrrfect sense! I was worried it was an injector setting that had to be diffrent for the stage 2/3 injectors. Rock on.

[esteinmaier]

Anything 1.0-1.2 is probably within range. High res helps a ton. I haven't done it yet, but adding a fuel pressure accumulator should help as well.

[Max Sleeper]

Hes right, HI-Res makes a huge difference.

I can hold betwene 14.6-14.8.

Also if you have big enough injectors you could do 4 injections instead of 2 it smooths out the idle for the v8 guys and gets them more low end torque, up top you will def need bigger injctors and using 2 at a given power level because of the need to shoot more fuel per opening, which will be shorter.
