now I've a smoke issue w/uncontrolled fits of anger and rage

[ellis93]

I'm not a diesel ricer,I don't want my truck to smoke out the hwy like I'm some flat brim hat kid. Since I've now fooled around with the dang full fuel screw I can not keep this dang truck from fogging the road while I'm towing,and I also noticed some haze this morning. It was pretty bad too! I've just now encountered this while pulling a bumper hitch 16' trailer and b2300 kubota backhoe,not heavy in the least.

Alright to correct it i've backed the smoke screw all the way out and now it's not even dreaming of touching the nut on the fuel pin,star wheel is down one turn from flush with its corresponding treads. What's it do.....it still smokes of course.
Now I'm thinking of advancing the timing alittle more,I've already have the tooth jump on the pump gear,so....how far more should I go before killing my low end torque and take off with a load(remember 20k often).
Any other thoughts are welcome as I REALLY hate that haze.....the smoke I will deal with if it can be reasonably controlled.

I always greased the cone and left my starwheel down just enough that the coils bound before the pin topped out on my ground cone. You could try turning that cone around backwards and seeing if t cuts your smoke down, if it does it may be time to step back to a stock cone and grind it yourself. (or leave it stock)

Yeah I had thought about going back to my stock pin....but I thought the m2 pin was kinda conservative,or rather seemed it was the lessor of what many run.

Oh....and don't be a d-ck

back your full fuel screw back out

[PToombs]

But how's it run? You may not get rid of the haze, you can try to bump the timing a little more. As for the fogging, try turning the starwheel up so it takes more boost to push the pin. That will slow down fueling when you step on it and should clean it up.

Well I meant leave the grind on the cone stock, but now I retract that and go with your interpretation. I'll be the first of many.

Oh schit....I've done it now

Pete,it runs like a rapped ape,I about slung that kubota off twice. I looked in the rear view and thought I seen it turn jb puke green twice.

I won't turn the screw back out daddy like

[cmann250]

I have 4x13s which should burn "dirtier" than your sticks and smoke is 100% controlled by my foot. I assume it is hazing black despite having boost? I can't even hardly lug my engine, but I don't have any smoke issues. I'd make a valet switch. My valet switch has been closed for several thousand miles. I don't miss the added fuel from the AFC. Just my $.02

[ellis93]

Ya,I'm gonna tighten the afc spring up tight like taco said and try that and im also gonna advance the timing some more,just a touch. the haze is where I'm most concerned,I think ol'RC might have wished it on me

[ellis93]

Hey.....what about the injector washers?

[DodgeFreak]

what size you have now??? thinest???

[ellis93]

Not sure,what they had came with installed on them out of the bag is what I put in. I call that blind Faith that they'd be right,but idk. They sure didn't look all that thin,I've used enough rearend shims to know .020 is dang thin and they didn't look it. I'm gonna call around tomorrow and see if I can scare some up. Can't hurt anything plus I need to retest my injectors anyhow.

I'd try raising the Star-Wheel before altering the timing.

Be sure that when raising the Star-Wheel, don't go so far that you end-up binding the spring and actually limit the depth the fuel-pin can go.


Remember: advancing the injection event timing puts more heat of combustion in the cylinder, and less out the exhaust manifold. With less out the exhaust manifold, there's less energy to power the turbo, thus, less boost. And it'll be slower spooling. Both of which contribute to no, to low boost smoke.

Gotta do the tuning thing . .

[RCCUMMINS89]

I was finally able to tune all of my haze out (warmed up of course)

Timing and really thing washers helped... on my pile the timing is crucial, I can adjust it 1/8" either way and it constantly hazes.

If it hazes at idle, then afc tuning won't do anything. If it is smoking bad under acceleration, but not at a constant speed then afc control will help.

whats your injectors pop pressure set at??
