Let me start off by saying that I am in no way affiliated with Quadzilla or Diesel Auto Power. I was simply asked to test the new updates because I have big injectors, I'm familiar with the Quad, and I know the person doing all of the tuning. This person wishes to remain anonymous, so it will stay that way.

On to the good stuff!!!

So what is V2? Basically it's a way to gain more control over the tuning parameters, with an emphasis on CLEAN POWER. I've got big injectors, and I've driven my own truck enough that I can drive it virtually smoke free, but I have to be very careful with the right petal (even when set to stock)

Here are the custom tuning parameters:

Alright, let's start with the power levels: 
0=stock
1=Power Percent (Explained later)
2=Fuel mileage (Same as the old number 1)
3=can-bus only (Same as old number 2)
4=can-bus + wiretap (same as old number 3)
and so on to the maximum level set is reached.

So, as you can see the first 8 parameters (through "TPS CAN Minimum") are the same as they've always been. They will function just like they used to.

The next two have to do with wiretap fueling. The "Boost Pump Scaling" gives the %specified of called for wiretap fueling if the boost is below the "boost pump low limit"
As an example:(Let's say it's set on level 10) In the pictures you can see I have the scaling set to 0% until 15psi. This means I'll get zero wiretap fueling until I hit 15psi of boost. If it was set at 50% I would get 600us of wiretap before 15psi. 
This greatly reduces the amount of smoke output without reducing your peak power.

Next we have Power Percent. This is the "new" level one! Here we have the percentage of stock power called for at all times. This is perfect to use for emissions testing, letting the wife/kids drive etc. This is also another way to reduce smoke if you're wanting to be really clean. 

Next is boost scaling. This is the same as it used to be. Just a smoothing feature.

Next we have PSI% listed 0-17 in increments of 1. This feature allows you to set the amount of stock power based on boost. It allows you to ramp up the power from 0-17psi, effectively reducing smoke and making the truck more driveable.

 

Now for my experience with testing.

 

Level 1: With my truck stock, I can floor it at any time and create quite a cloud of smoke. You'd swear I have a tuner cranked, but it's not. With my truck set to 70%, I can floor it while doing 55mph in 6th and get as big of a puff as a stock 24V. Meanwhile it'll pull about 34psi @ 2000rpm and 40psi by 2500rpm.  It does make the truck a little doggy, but I could adjust the percentage up as I saw fit and still keep smoke to a minimum. This would be perfect if someone were to borrow my truck (never going to happen but you get the point) They could try to hotrod it as much as they want but won't be able to. I do think this would make emissions a breeze to pass, and it could be used as a safety device to keep the truck from being stolen. Essentially you can set it to 1% and the truck would only idle.

 

Now for the PSI%: With the power level turned up around 1500rpm I can stab the throttle (0psi of boost) and get nothing more than a slight haze until the boost picks up and the quad starts fueling hard. Spool is still excellent under these conditions, I just need to work on my top-end fuel command to reduce the smoke up there. This has made the biggest difference in CLEAN power. The quad is essentially rolling into the throttle for you as the boost comes up so you don't cloud the highway when you get on it. 

Now the "Boost pump scaling" and "boost pump low limit": The wiretap fueling is essentially it's "own" programmer. It doesn't follow the rules of the can-bus fueling. This was taking effect in my description above because it doesn't wiretap fuel for me until 15psi of boost. Thus why it's only a haze until 15psi.

 

Now, what I'm not quite happy with yet. Off idle, if I stab the throttle on level 1 I get a puff of smoke. I am told this is because of where the quad takes over and starts controlling things. It's being worked on and should be fixed soon. Other than that I'm very happy! I do have only 20 miles or so of testing, but this does look very promising. I'll be putting 50 miles on in the morning and 50 miles in the afternoon, so I'll have more info then.

Any questions post em up and I'll do my best to answer them. The future of clean power for 24V's looks promising :stirthepot:

Thanks for testing that @TFaoro

Yessir. We'll get it figured out one way or another. 

Searching through the code to see why it suddenly goes to a fueling message of 1....it shouldn't but yea.

figured it out I think.  the code was set to only ignore the ecm if TPS was always > = the tps reading from a few mills ago.  I am guessing the ecm reported 99% TPS for a split second and the quad jumped back to oem fueling.

 

I adjusted the tune to be tps > last_tps - 5% so you can let up slightly.

I'm figuring out to do the timing section of the Quadzilla now. The biggest thing I figured out is to watch the stock values first for part of road trip then figure out how much timing you want to give total. Then you can tweak the other setting like adding cruise timing, your load timing etc. I'm still working the method of figuring it all out with the timing settings so more to come. This will be based on the economy side more so than the performance side.

@Carbur8tr  I am still working to extend fueling further.  as you approach 3500 rpm the ecm get's more and more picky.  If you hit 3500 and the canbus message isn't at 0 then truck will actually shutdown.

Lol I had a pretty noticeable back fire.  She was not happy around 3600.

Also I have timing recorded over 26.... I didn't know that was possible.

 

30 is possible according to what I have seen the ECM ask for when cold.   

Hmm, yeah, I actually have quite a few numbers over 26.  I think you might be on to something.

 

Keep in mind we can ask for whatever we want, the vp44 will do what we ask until phyiscal limitations are hit,  IE we can ask for 36* and it will show 36 on the screen, but it will only actually be doing ~30.

 

I can't tell your exactly where the limit is, but I do believe it is above 26* as Tyler sent some OEM data logs with timing approaching 29*.  I can't imagine that the ecm would ask for more timing than possible.  

 

 

I also want to point out that is it now possible to mechanically advance the pump by 5*, 1 tooth, and pull back timing in your Quad by 5* down low while keeping timing high up top.  You will effectively get a very controlled ~35* of timing if you choose to.  It would idle funky, but once you got on the throttle I don't think there would be an issue.

And video time

 

 

 

You can see a little bit of fluctuation in the smoke when up towards the end of the rev limiter.  Not exactly sure what was going on but you could feel it almost surging or trying to.  Smooth pull for the most part though.

 

Let me know if you suggest anything different with the "daily" tune below which is what I ran on during this video. Honestly I think I need to pull the stretch down to maybe 1650 or 1600 to see if I can clear up just a little of the smoke.  Other than that it pulls extremely hard.

What RPM is the surging / smoke puffs happening at? 3000+ rpm?

 

I'd prob drop your upper end timing a bit and see if the surging stops.  Maybe try 27* maybe 28* really depends on where the popping is happning.   If max is at 30* then you will see 26* at 3000 rpm and 30 at 3500.  That's a pretty aggressive ramp up while canbus fuel is falling.  

 

 

I am assuming you have studs?  your stupid tune has a VERY aggressive timing map haha.  I don't know if I would run that aggressive down low

Edited by Me78569

I'll drop it to 26 at max and see if that helps.  

also I can't remember what your fueling setup is anymore.  7 x .010's ?

7x.09s.  I believe the same you're running if i'm not mistaken. 

Wanting to step up to 11s but honestly being that the truck runs so good and I literally never have to worry about EGTs I just can't bring myself to do it.  now with that though I have tossed up the idea of going to a 63/68/14 and 7x.011s but who knows if that'll ever happen.

 

got ya.  

 

If you are ok with the smoke level then leave it. 

 

Does it smoke on lvl3 driving in the same manner?   If it doesn't then bump your wiretap low limit psi to 8psi and drop stretch slightly, but I am running 1750 in my tune and I don't have wiretap smoke.  by my tune starts at ~%88...I think

Edited by Me78569

That I don't know it stays on lvl 5 (Max) all the time.  I have wire tap lowered because I find that it helps with smoothing the power curve just a bit.  Not quite sure what the deal is but the higher I go generally the more of a kick I feel when the tap comes on.  

 

I think most of that is due to the fact that the truck builds boost insanely quick so when it finally comes on the map is jumping so quickly that it's causing a bit of a surge in the power band which is awesome if you want to blow the tires off but annoying in some ways as well lol.

To me the "popping" seems like it happens right when canbus hits zero and wiretap is still fueling. I'll drop my timing and see if that fixes it, but I doubt it. Higher timing at higher rpm is normally a good thing. Although nothing with a VP seems normal

Once canbus falls out wiretap is left "guessing" for lack of a better word.

 

 

Tyler I did get fueling extended to 3400.  Not full fuel but a more delayed ramp down.  I am gonna slowly beef up the fueling at the end until we find the limit.

Edited by Me78569

There's definitely more out there but question is how much and at what cost.  I wonder if someone has a PM3 that we could borrow to see what they are running in the higher RPMs.  I've always heard good things about their fueling past 3200.
