I didnt want to mix up the threads by posting unrelated information so I figured I would start a new one.  This thread is for figuring out what works and what you find your truck likes.  

 

I did some more datalogging as of late and found that a more aggressive timing curve later in the rpm band, say 2500 + rpm, seems to pull harder up top.  Previous I was running tunes that maxed timing at 26*.  I took 2 tunes copied them and ran them back to back on the same stretch of road, same conditions.   I was not using wiretap for this so I will leave those details out

The interesting thing is the tunes are the same except for the timing above 2500 rpm.  If you look on the graph rpms hit that 2500 rpm mark at about line 20-21, each line is ~.3 seconds so 3 lines = 1 second.    You can see where timing jumps and also where boost jumps. 

 

Now keep in mind the graphs are not exact so take them with a grain of salt, but everything appears to show that the tune with higher timing up top gives faster time to 50 mph, and a faster ramp up of boost.  The higher timing tune appeared to reach 50 mph nearly 1 second faster.

 

as always studs are a good idea, but I am fairly sure anyone can run this timing above 2500 rpm.    If people are not blowing their heads off left and right with other tuners then there is no reason why this type of timing curve will hurt with the Quadzilla. 

 

 

Food for thought, open to other thoughts.

Ya I figured that was the case :/ sorry man, hope she quits weeping

hpw do i adjust idle timing?

 

Can't be done. Once the APPS sensor is return to idle the Quadzilla drops out and ECM takes over. 

@Dodgeih have you inspected the injector yet to make sure that the mating surface isn’t compromised in any way? If you’ve checked everything else then that’s pretty much the last stop. It’s either that or you’re actual injector line is leaking due to a similar issue. 

 

On the haze note, they seem to be very comparable to the .009s I just took out, and better than the previous set of .012s I had from dap. I need to take another video when it’s warm. That was right after the install and there was still air in the lines so might have been part of what we were seeing.

@Carbur8tr I haven't checked injector yet but like I said the tip on injector line has very small pitting..just picked up a set (used). They are getting shipped out today... I think that's my issue. But I will find out soon.. I will check my injector when I do lines and o rings thanks for the advice

im only on page 7 as ive just found this thread.  Ive been quiet for a while now.  I have  fuel boss mechanical pump setup i have a quad and a set of dap 7x11 sac. injectors and quad are great. truck starts way smoother and idles quieter.  I have the 6 speed and i have an offidle problem that i nearly have dialed out with the quad. It involves fueling and timing adjustments. i have noticed however that it idles most of the time at 15.5 deg timing. the few times it drops to 11.6 it drives and takes off way smoother and antistall works great.  hpw do i adjust idle timing?  im interested in some testing and whatnot but need help with a dual disk clutch and headstuds for the project.

Idle timing is largerly based on IAT and ECT temps.  are both sensors working %100?  15.5* of timing at idle tells me that either the truck is cold  during these times or you have a bad sensor.  

With minus temperatures outside and IAT down to about 40-50*F will product idling timing as high as 16*. 

I def need to make my own thread. I would also like to have a YouTube channel. But I'm so busy I don't have time for either unless I can get a camera guy to follow me around. I wanna check out the video on the sensors for sure. I don't know for sure why my timing is so high at idle. Temps are negative and single digits here in Indiana but at certain times it will be hovering at 15 and with a blip of the throttle or a restart from say a drivethru and timing will drop back down. I would like to start making graphs for my data logging but I don't have Excel and don't really want to pay $150 just for the option of graphing. Really the antistall is the only problem I have with the 7x11 dap sac injectors. And like I said in my previous post I almost have it dialed out to where the trucks drives just like stock. Time will come and I will get a thread going and elborate more on my setup and future mods.

You can create charts using open office or libre office, both are free.   I use excel because I have it.  

 

I would just say your timing differences are IAT temp related,   you will have to datalog to confirm, but it sounds like typical behavor.  

Little bit of driving.  Still working on the tune and I know most of you will wonder why I'm only at 80% here and really I'm just trying to recreate the same "feeling/smoke" as what I saw with the 7x.009s.  Even at 80% I am seeing 43-45 PSI so I don't plan to go much further until I can work out the details on compounds or a larger single.  (More than likely it will be back to compounds)

Like myself, I use Libre Office on Ubuntu Linux to produce the graphs. 

Initial thoughts:

I think with the SAC even at the high bar there is just a certain amount of smoke that we will never be able to clear. I plan to pull back timing reduction to see if that helps and maybe lull the mid range just a little.  Most of the smoke is from 5-15psi range so I think if I take a little out of this area then I should be able to clean it up a little more.

 

Starts:  No difference here.  It should be in the 20s here tomorrow so we will have a good test to see how this has been effected

Idle: Is fine, nothing odd or out of place

General driving:  More power all around from top to bottom.  Turbo spool is incredible even under light throttle, huge difference.

Overall: Very pleased with the exception of the off idle delay that I'm trying to fix.  @Me78569 we have talked about the off idle lull before but I have never had to deal with it until now, any suggestion on making this better?

Edited January 15, 20187 yr by Carbur8tr

@Carbur8tr Are you running any wiretap? 

None what-so-ever because there is no need.  These injectors have plenty of fuel without wire tap. 

until you slap another turbo on her

Lol I’ve had the disease for a while now. Never leaves just comes and goes haha. 

Terrible disease! Just wish was my trans was already done.

Edited January 15, 20187 yr by gipperkid

Btw I meant to report with 100% certainty that when I drop into gear and the truck dies the rpms do not raise at all prior to stall.

 

Also here's my timing/stats on a cold start.

Ughhh lucky! Lol

 

I hope I can weigh in soon. I feel like im getting left in the smoke (or lack thereof)

Im still working on a tune with my 7X13 sac at 365bar. When i come off the throttle or even just idling in gear and push in the clutch it acts like its going to die then over compensates and revs up and so on a few times. you can see it on my graph. Also any tips on my graphs? So far starts good like stock but also trying to tune out the loss of power right off idle. Tons of power on tap.
