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

Mine too lol.  

 

I actually have never seen a 1691 code on any truck since I bought my truck.  Thats an intersting one.

Well, another VP44 has received a kiss from Death today.... The P1691 code showed up, went away, and thankfully hasn't returned as of yet...

Coincidence that this happened a mere 8 days after @TFaoro's pump died? I think not!  Moral of the story: If you are around with Tyler's truck breaks, run! Otherwise the bad juju will make it through a tow strap and into your own truck... 

 

Now to wait for the inevitable death of my pump

 

See, the Smarty lists code P1691 as "Fuel System ESS RPM Error" in their little booklet, so I was thinking I could hotwire the FASS if needed, but then Tyler taught me better and his exact words were "you'd better pray that code doesn't come back".  And praying I am.

Got it from here:

 

You still need to test for AC noise though. 

@TFaoro I found that article too, and the VP passed it earlier today.

I think that code is a result of the ecm asking for xxx fuel, then not getting a response back from the vp44 saying " I fueled xxx"  

 

I would clean your connection to the vp44 and the ecm, use dielectric grease on the plugs.

however most importanly don't park next to tyler....ever.  and don't EVER connect your truck to his in any way....  

It's strange, the truck will drive just fine, and then there will be one time where I push the clutch in, it'll rev up to 2K, come back down, shudder below 500 RPM and die.  Then I can crank and crank with no smoke, and if I let it sit for a few minutes, it'll fire up like normal and I can keep going.

or you have fallen victim to none leaded soldier...

Well it happened again on my way to the store. So I'm assuming it's ded.

Lesson learned. 

Bet money it runs like a top in the morning until it heat soaks

Bet you're right. Too bad I'm rockin a Chevy Equinox right meow.

Go start your own "Trevor" thread so I can clean this place up  

Thank God they dont make a 2000 mile long tow strap!!!!!!!!!!!

Im actually slowly gathering parts to cr my second gen lmao but I wanna see how quad does 

Well something to keep in mind with the Quad.  

 

The output and the maxes of the system are exactly the same.  We are not doing anything that wasn't done before in terms of fueling.   Most of the time the V2 stuff is actually less aggressive than the old tune, as there is no need to be fueling aggressive with bigger than stock injectors.

 

The limits of the VP44 system are all the same, the Communication protocol is all the same, its only the calculation going on under the hood that is changed. 

@c.englund  Have you flashed the V2 tune hosted here yet?  Have you updated the phone app to the one hosted here?  Next set your Quad to lvl 1 and tune using valet mode setting.  Figure out how much fuel you can use off the line to keep smoke down and power up.  

Once you have a good starting point come back with what your starting point is.

@Me78569 @Mopar1973Man @TFaoro Quick question, don't want to start a new thread, I put 6 qts. of Mopar GL-4 in my NV4500, it was low, shifting weird I think the guy who rebuilt/owned before me used the wrong oil.

 

Basically I pumped in 6 qts through the top PTO bolt hole which is about 1/2" higher than the fill port.

 

Thoughts?

No problem. I'm about 2 inches above the full hole. Won't hurt a thing.

After some feedback from various people @Quadzilla Power was good enough to bump the canbus low limit for 0 -4 psi settings to %125 rather than %115. 


Really for stock injector trucks only, but  that does mean that Torque mangement should be overcome if you set your race tune to be %125 off the line.  

Nice
