Smoke Control

Actually I realized that in that particular program I was a little more aggressive with the Base SOI map in the light throttle ranges.

I switched back to a program with the same PW map with the easier timing curve and the slow speed issue went away but.............I still have the rolling idle.


Sooooo quiz away..........pleeeaaassseee.

What is your minimum IPR duty cycle parameter? What is commanded in the base IPR map? What effect does the ICP have on your PW?

[907DAVE]

Min IPR Duty% Parameter is 4.98%

Duty Cycle Maps says should be around 4.5% @ level 20 on the Regulator Flow (which I am not sure what that really is).

As PW drops ICP goes up.........right?

Just to be curious, what's the fuel pressure in heads under load? Those injectors have got to tax a lift pump pretty hard.

[907DAVE]

Fuel pressure is not an issue as I am pushing close to 140 gph @ 60 psi through the heads at all times.

[thedieselguru]

That's a bunch

[907DAVE]

You are right! It uses a 5/8 pickup tube to the pump/filters then 1/2 all the way to the engine where it splits to 3/8 to feed the rear of each head.

Well after taking yet another look at the PW map it appears I took close to .3 MS away from my Idle range..........I added that back and might give it another try tonight.

I just cannot wrap my head around what that actually did to my ICP/IPR%.
