The version of the app in the play store does not have an "import" button.  

 

Make sure the app you are using is from the play store.  Then you open up your "downloads" program on the phone, click the tune, and it will bring up hte iquad to "import"

Mike's having this issue as well.  I can't reproduce it and I am guessing as to why it is happening still.  What RPM does the issue go away at? 

 

Sorry Nick/Mike, I didn't see the other post. Stops at pretty much exactly 1000rpm. Gets a little better by 960, gone by 1000.

[Me78569]

I posted a tune for you to try in the other thread.  you should have notice of it.

@Me78569 just to be sure can you post a link that takes me to the play store with the most recent version of the app? Also how did you get @Mopar1973Man 'a eco tune? When I go to the repository only your tunes come up?

Yeah I pulled it till I can things fixed. I'm still not getting very good MPG's from any of the tunes and battling this from the start. I can touch 20.x once in great blue moon but most are 17-19 MPG which is just as good if I just removed the entire Quadzilla and ran without it. I've done that a trip or two to see the offset it pretty minor. 

 

I'm still running 250 miles every Tuesday, Thursday, and Saturday. Some day after I wore my truck out I might get back to my awesome mid 20's. I've not seen any of those since last fall which I done a few and then it was gone.

interesting note..

 

While towing on flat ground today at 65 mph I got curious what OEM timing was vs my tow tune timing.  

 

It was a very long flat straight stretch of road.  Sensor data was

 

Boost: 3 psi

TPS %: 22

EGT: 800*f + - 50*f

canbus fueling: ~1000 or right around %25 load

 

My tow tune has light load timing until %35 load is reached, so my Quadzilla timing was in the 18.5* range.  Good bit of rattle, but nothing to worry about in my mind. My daily tune sits right at ~20 * at 65.   

 

So I flipped over to OEM to see what the ECM was wanting at this point and found that timing was at 12-12.5*  EGT's didn't change enough to report.   

 

 

Did roughtly 320 miles, burned about 3/4 tank, Somewhere in the 13 mpg range pulled

 

Ute pass in el paso county

wilkerson pass in park county

hoosier pass in park county

ute pass in grand county

 

way better drive than i70

 

all that to say that I didn't really find anything out, but I was shocked how low timing was while towing on flat ground.  A stock injector truck would be in the 11* range in the same situtation.

I've gotten similar results. I was cruising at about 103 km/h on Friday evening. Flat prairie highway. I was running around 18.5° timing on level 3, flipped to level 0/1 and stock wanted around 12-12.5 degrees. On level 3, I was running about 3-4 psi boost, maybe 780ish° egt. Level 0/1 changed that to 840+° egt and 6 psi. I have been able to recreate this scenario quite a few times now, and it makes a lot of sense. I forgot to check what canbus fuel was doing but I know I saw engine load change a little.

What where your rpms?

 

What kind of trailer?

That's why I keep reading this thread. The differences in VP vs CR appear to be huge. 

 

What I find interesting is looking at the injection timing table in UDC Pro for VP trucks. It doesn't show anywhere near the timing you guys are talking about for OEM timing. 

 

 

For a CR example my latest tow tune has the most timing in the 40-60% load of any tune I have tried for 1800-2200 rpms. 

 

At 65 I am turning 1800 rpms in 6th, which is a bit low for heavy loads but okay on flatish gound and smaller loads. 

 

At about 25% load I would be really close to 800° as well and 2-4 psi... so very similar numbers there. 

 

At 25% load I am running 35mm3 (525us) of fuel and about 15.5K psi of rail. My timing is a whopping 5° and the pilot is 10° ahead of that. It's still a little higher because that's a low enough load I'm still in the cruise profile there. If I increase engine load to 40% which is going to happen on any grade over 1% I am down to 1.3° of main timing for a 55mm3 (772us) of fuel. 

 

 

[Me78569]

1750 rpm, it's a 19' on the floor gooseneck at ~5k.

 

 

 

Keep in mind there is a missing base timing table in UDC Pro for the vp44 trucks.  Jdonoghue showed good info on this table and how it worked.   I attached some of the info from his adventure ~10 year ago.

The timing numbers we are seeing match up pretty close to the timing range p7100 guys are using and the calculation we are using make "sense" in terms of how you would structure a command on a 12^2 message.  

[AH64ID]

I guess MADS need to get us that base table info!

 

Sounds liike a fairly easy to tow trailer, at least in terms of wind resistance.

That was one question I had about udc pro that the people who knew just responded " you don't need it" or "you don't understand how the ecm calculates timing" 

When I ask for an explination I get silence.  

I still can't look at the udc tables and see what the output timing would be.  Or at least see a timing number that makes sense compared to what I have seen.

 

The trailer tows pretty nice.

The pressure of the common rail would explain the timing differences you are seeing @AH64ID

I know the CR's run more pressure,  but I recall seeing some VP pressure numbers that don't put it as far below CR's as I originally thought. 

 

IIRC a VP is capable of 150 mpa and 03-07 only run up to 160 mpa stock. I run 155 mpa on my personal custom tunes, and even as low as 150 on some of them. 

 

I'll push to 180 mpa on a race 5.9 if needed.

Better be higher... Just to pop the injectors on VP44 is 310 bar.

 

 

Just checking 18,000 PSI which I've seen on CR engines as a measured high pressure turns into...

[Me78569]

but we have to wait until pressure hits that mark, CR trucks have that pressure on command.

[Mopar1973Man]

Just my OBDLink LX sees CR rail pressures looking at several stock trucks I've seen in the range of 16,000 to 18,000 PSI typically. As for the VP44 injection I know we have to reach over 310 bar to just pop the injectors.

Your right. We've got to pump each line to over 310 bar to get spray. CR I've seen roughly 5,000 PSI at idle (IIRC) which is about 344 bar. Like my current injectors are popped at 308 (4467.16 PSI) to 312 bar (4525.18 PSI).

 

As for VP44 trucks I know the starting point but as for high point... That's unknown to me...

 

155 Bar = 2248.08 PSI

150 Bar = 2175.57 PSI

Errrr.... I meant mpa. 23,206 psi = 160 mpa. 

 

VP's can push over 20K psi IIRC. 

 

I idle around 7K psi.

Thats got to be the biggest difference for timing. 

 

Whats interesting is WOT timing isn't as different at higher rpms. 

[Me78569]

higher the RPM the shorter the line delay is.

Yep, and I pull my pilot at higher rpms which means I need a little more timing for the main.
