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.

No clue, my truck doesn't have TM so I can't tell you how it interacts. 

 

Throwing the canbus at %150 across the board and a ton of wiretap will try and overwhelm TM, but the longer you spend in the 1 -25 mph area the more tm will pull fueling.

So this new tune is like 2 step but fr our trucks then. Sweet. Does this work on a manual transmission?  If so I want to try it

You can't put load on the engine enough to build boost without roasting the clutch.  It will in theory work, but I am guessing your clutch will be smoked before you launch.  

If you give me some beer I'll try it with the dual disk....

 

 

 

But I actually like my trans in one piece.

Have a video of the 5 psi launch?

Nope not enough hands

Also where in the quad does this code get written? Or is it tune of some sort. Sorry if it is a dumbass question, still learning the V2.

 

It's a difference base flash.  so the box under the hood gets a different flash, with 1 line of code changed to use the bosot defuel for staging rather than overall limit

So say I had the 2.7 flash, that gets replaced with a different flash or a 2.7 flash with the added line of code?

the 2.7 code would be replaced with 2.7+staging 

 

But again this code is a race only type of thing.  Using the staging function will cause unbelievable stress to the drive train

Can you write a code for a 2 step type of deal for us manual trucks

Edited January 17, 20187 yr by Ekillionc9

no, manual trucks cannot apply load to the engine at idle without slipping the clutch.  

 

Without a load to apply the engine cannot build boost

Anyone want to do full auto swap for my nv4500????? PLEASE!!!

Haha this sounds fun, mabye after I get this tune dialed in lol.  It's almost there.  I think we made some good head way today but the truck was covered in ice including the mirrors so no telling what was behind me.

I have tossed this up time and time again.  I think I just need another truck that has an auto already in it haha.

Yep.

2 step doesn't load the engine it just limits rpm. I think it has an upper and lower limit. So say you set it at low 2000 and high 2100. It would bounce the Rev limiter between the two specified limits. 

oh, yea nope can't do that either.  the ecm gets VERY mad if you mess with fueling vs rpm.  the ecm goes into a runaway mode protection and shuts off.

I'll just take the NV4500 for a spare...  Don't have a 47RE to give up.
