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.

Yes,  working on something else for the tune before release. 

Anything exciting?

Just trying to help manual trucks not surge under 1200 rpm when the tune starts in the sub %70 area

That would be nice let me know if I can help. Taking off from a dead stop is a little tricky to not make my truck jump right off the line and make a big black puff. 

yea,

 

hard for me to code since I can't personally test the results.

Try this flash. It has some smoothing in place and a fix for the overfueling you are seeing beyond 3100.  ( this only disables the hard fueling if the 30 psi setting is sub %100)

Smoother but still touchy when going from a dead stop. I think me being so low under the stock fueling makes it hard because if I set it to level 0 it's way better but can get smokey. 

 

Very hard.  

 

Touch as in too little or too much fuel?  What rpm and what throttle is it touchy?

 

I am still working on getting the map right for the office handoff but I think this is better

Figured this would be the thread to ask. Wanting to get the quad installed. I have been running the Edge EZ on level 3 for the past year. Is the stock injector daily tune basically the same as an edge ez?

Edited February 3, 20187 yr by gipperkid

no clue, 

 

It prob isn't as timing aggressive up top and might be a bit lazier down low.    However you have a few pre-built tunes like the race tune or tow tune.

to much fuel coming off idle when your trying to ease into in from a dead stop at like 1-5% throttle.

I think that I may have found some of my runability issues.. Cam sensor failed... Also found out a bad cam sensor can cause a ton of very very strange symptoms! Lol got my fuel leak sealed up finally as well.. Now just to wait until the roads dry up after the 6"of snow tonight so I can really put these to the test! 

What issues did it solve?

Well I'm hoping that it solved the chuggin under high load high RPM. But it was causing some very strange things. It was making the grid heaters cycle so hard it would kill my headlights and all my interior lights. Sometimes it would even kill the engine it pulled so hard. Then it randomly overcharged to 18 volts. All this started happening one night. But the three weeks prior every time I would do a hard Pole right when I let off my calf would drop off and I would get a check engine light. It was starting to idle fairly rough randomly it would just kind of get a quick Miss at idle and sound kind of goofy then it would come right out of it and just go back and forth. That is gone now I have not had an opportunity to check to see if the high load chugging is gone because the roads have been covered in ice and snow.

I read through this whole thread and understood a quarter to half  of what was explained here. Lol I’m interested. What was the final concenses on the higher pop pressure? 

unless you can explain your need for higher pop dont bother.  

Haha gotcha!
