Single shot injection?

powerstroked08 · Jun 22, 2013

Ok so i might as well post an update. I made a tune with what I would call partial single shot injection. And it seemed to work well.

powerstroked08 · Jun 22, 2013

I would like to see the milage differance between the two tunes but i dont really drive in an area that i can get a good idea of mileage. So i guess when i can get a good read on what the differances are i will let you guys know. But power wasn't down that I could tell smoke wasn't bad and the noise wasnt bad either. I really think it would make decent mileage on the highway if anybody wants to try it.

Heck yeah man. Definitely keep us up dated. Maybe some people would be willing to try it

Powerstroked08, I'm assuming you just turned off one of the two pre injection tables?

Yes and no. I did turn off the one preinjection table and then I also turned off the second pilot injection at "cruising" speeds.

I'm kind of attempting to ease my way into removing the pilot injection to a point. My thoughts were to keep the second pilot event to keep noise down while still "preheating" the cylinder for the main event. Then I removed the second event at the highway speeds to save as much fuel as possible. This way you would already have boost built up so smoke wont be much of an issue if at all. Plus at highway speed you really dont notice the noise differance. I would really like to try this tune out on the highway soon! I think it will do well. I did try it around where I live but I'm pretty much in the sticks so I didn't get much time at a steady highway speed.

Haven't been on the highway yet either but all my pre/pilot injections are removed. Only difference ive noticed is its louder, not huei loud but deff louder than stock. Oh and u need to advance ur main injection timing on the 500-725 rpm area to allow the truck to start like normal. Mine took longer to crank and would haze white smoke until I advaned the timing a few degrees.

powerstroked08 · Jun 23, 2013

I wish i knew or had access to some 6.0 timing tables, that would help out a lot as far as to where to put the timing at. Even if we split the differance to start off and worked with it from there. But either way thanks slo dzl for the heads up on the timing changes for start up.

Stroked777 · Jun 24, 2013

Can you guys post screen shots of what you did? And SLO DZL how is it running without any pre injection cycles?

Maybe someone on the h&s forums has a stock 6.0 file you can compare too and work from there

What do you set the pre injection table to all zeros?

powerstroked08 · Jun 24, 2013

There is 2 preinjection activation menus to either turn it on or off. 1 being on and 0 being off. There is preinjection activation 1 and preinjection activation 2.

Stroked777 · Jun 24, 2013

ok i just turned off prev. 1 and 2 activeation switch , so how do you advance the timing? and by how much

and also a little off topic, but i see there is post injection, if thats set to off that mean no more dpf right?

SLO DZL · Jun 25, 2013

So far the truck is running fine, wouldn't know I had done anything to it if it wasn't louder. On the timing, I just started advancing it a couple degrees at a time untill it started like normal again. Figured if the pre-injection shot was about 9* BTDC, then working the main from 4* ATDC slowly to about 3*BTDC wouldn't be to big of an issue.

Not 100% on the post shot being for the dpf but it would make since if it was.

powerstroked08 · Jun 25, 2013

Yes the post injection is for the dpf to regenerate.

Yeah good idea I didn't think about doing that!

Dieselfever · Jun 25, 2013

I would imagine the 6.4 injection system is a bit faster than the 6.0's so you might want to take that into consideration also.

you got a screenshot of the timing tables? and do you do all the config and temp tables to the same values
