How is the driveability for the 60 lbers? Do they not atomize the fuel enough for low rpm combustion?

 

It's not bad once you get them tuned in.

 

hmm define not bad... I've seen people put up with a lot thats "not bad". I guess I'm just fussy.

Is it bad to run injectors at or near 100%IDC?

What does running them above 100 do... they can't exactly quirt in more fuel can they

Ok done whoring up your thread sorry!

 

From my understanding anything above 100% just means that the PCM is commanding that much fuel but the injectors are not keeping up. Also, above 80% IDC the injectors are no longer linear and therefor no loner predictable.

 

Over 100% IDC you get way lean way fast....This just happened to me because of a wastegate issue. Put me at 14.0 AFR at about 12 psi

 

100% duty cycle is the injector pintle help open, or static. Obviously if duty cycles over 100% are commanded, the injector cant flow anymore, the engine goes lean.

BTW injectors are rated at 100% duty cycle or help wide open at usually 3BAR or 43.5psi rail pressure. 50% duty cycle is 50% of the time open, 50% of the time closed.
