PW observation

This is the FDCS signal over the feedback signal (slightly delayed replica of FDCS). You'll notice that with just moderately stabbing the throttle off idle (very low RPM), we already see about 75% duty cycle.

Still think full PW can be achieved at high (3000+) RPM with stock electronics?

By "full" I mean enough to empty the injector. Keep in mind that the window continues to shrink with higher RPM.

Re: PW observation

That isn't really giving anything away, Pretty much every 7.3L PSD on here does that, you just have to be able to look at it.

Re: PW observation



are there seriously some archaic tuners out there that think they have full control of PW at rpm?

I know that there are plenty of 'minions' out there that think that their tuner has full control of the PCM & injectors...or maybe they just "wish" that their tuner has full control...

take care~

Re: PW observation

Golly , gee whiz.. you mean theres NO ONE that can overcome this....goshdang gump......I mean, I THOUGHT i heard of this one truck that turned, oh......4,200, 5,200 rpms still making spinny thing noises and smoking.
Hmmmm. Guess it was my magination. And here all this time I thought there was a cure. Maybe that banks guy has a cure? A new box thingy that fixes all of that? . Wait, what was it called....?? I think that Billy Mays guy sells it on late night tv. And you get a free set of knives with it..
