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

Changed the title for SEO reasons

 I just flashed and downloaded the latest update this afternoon, and also chose normal fueling. I copied a few tunes that I found on here and was driving under the performance tune (moparman posted) and for some reason iquad on my tablet quit. However, I could tell that it was still in the performance mode as I was driving because the acceleration pick up was far better than stock.. What do you suggest I do?? I  tried turning the truck on and off I also restarted the tablet and made sure the Bluetooth was still connected.  My truck is mainly stock I don't have injectors I don't have any turbo upgrades I have a fass 150 in a 5 inch Turbo back exhaust.  The truck is running fine I'm just not sure how to get iquad working properly on the tablet

Wanted to add pictures

Uninstall the app and reinstall, make sure you are running the APk from the thread with the flashes.

10-4 I'll look into it first thing in the morning. Thank you

Someday I'm going to convince you to do some work on the backdowns. The main one I'd like to see is EGT defueling smoother than just jumping levels. 

Agree, I'd be useing defuel options if they were smooth. I used it few times and sounded like my truck blew up. So disabled them. 

It would be nice for Towing if you weren't paying attention to gauges and started to lose power smoothly, then you would just downshift knowing that you just hit one of the defuel parameters.

Right here...

 

Everything is operational. I will be taking a 500 mile road trip starting tonight. Hoping to mess with different tunes and try out one of the economy tunes. Thanks everyone for all you're hard work you have put into this. This tuner is a game changer!

Hope it treats you well.  If oyu have stock injectors I would keep cruise timing in the 1* or 2* range.

Hey guys, getting my truck back Monday! Can't wait to update the new flashes and get rolling

I'm now in the phase testing 1* of cruise timing.

I'm at .1 which is having the truck hover in the 17 degree range and so far it looks like this tank is going to come out with better mileage.  Will have to fill up tomorrow so I'll let you know what I find.

 

On another note @Me78569 and @jlbayes, I've been reading a little on the VP mainly just trying to get some more info on pop pressure and so forth and most of what I found is just hearsay.  What I would really like to find is some information on "max reliable pop pressure" that's attainable.

 

Two concerns though, 1 the pump itself and the max pressure it can provide to an repeatable injection event, and 2 the happy medium between atomization and risk breaking a tip or fatiguing the spring.  Any thoughts?

Keep in mind that pop pressure is only ~4500 psi, the vp maxes out over 20k psi I think.

 

I doubt 20 or 30 more bar will make the vp angry or damage stuff.

 I can say I've tried 4.5* all the way down to 1.0* of cruise timing with no change in MPGs so far. I'm hovering at about 15* total timing at 55 MPG and 16* at 65 MPH. Still hanging around the 18.7 MPG range. I think part of this is the limit of the winterized fuel I'm using.

I've read 20k as well but find that hard to believe considering that would be close to 5 times that of spec which is 4500 +-250(per the manual).  If it was though I wonder if timing becomes an issue at that point?  Also I would have to wonder how long the injector pump could sustain that pressure.  You could definitely empty the barrels/plungers a lot faster which might mean more RPMS up top.....

 

Now you really have me thinking.

I texted a builder. We'll see what he has to say.

Very curious to hear thoughts

4,500 PSI is the pop pressure of the injector. Just like all the fuel system they all raise the line pressure to throttle more. 

"No point in going over 300 bar, often see stalling issues there or higher. Manual trucks tend to lope. I've seen better results at 290-300 bar."

 

What he responded with.

Edited February 10, 20178 yr by jlbayes

Can you respond back asking what would happening if we were to manually offset idle state timing?  

 

He wants to know what exactly is trying to be accomplished with the increased pop pressure and subsequent timing increase.

Clean up idle haze due to large injectors.   Since we can control timing now we should reevalutate what can and can't be done with various setups.  End result of trying to bump pop pressure would be to try and create a better atomization of fuel.  similar to what CR trucks do with their tuning.

 

 

 Back on the Quadzilla side of things.  I have a working defueling that reduces canbus fueling on a % rather than dropping levels.  Now I just need to do some testing and see how much fuel has to be pulled to prevent overboost.  

 

Anyone want to test and give me some data logs back?
