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

I'm looking forward to see were you like things set after getting some miles on. I'm also curious to see what settings you prefer for towing. It's going to be great to adjust it to run cleaner. I hear Colorado sends out these little white pamphlet that say Visible Smoke...haha evidently people can call in your plate if they feel you're vehicle is smoking excessively. Don't ask how I know...

Yeah, I've gotten one of those little pamphlets....OOPS!

50 miles on it this morning. My happy spot for level 1 is 75%. 70% it was just too lethargic. At 75 I get a tiny puff of smoke and boost ramps up to 40+ as rpms increase. I have a very hard time breaking 1,000* exhaust temps on this setting. Running as hard as it'll go from 0-75 exhaust temps were 985, and boost 42. All with just a baby puff of smoke when starting in 2nd. I did have it to the floor from the get-go too. No rolling into it. I'd get a video if I didn't have to steer, shift, and record.

 

One thing I'm not happy with is level 2 (the new level 1) It seems to be defueled from what it used to be. It's acting just like level 1 for some reason.

 

I'm still working on the can-bus tuning. I've got it to where low end smoke is very low. Just a slight haze and a puff. The puff comes out when the boost climbs above the 17psi threshold.

The only thing I'm not satisfied with here yet is the jump once it's above 17psi. When I have it to the floor it's not an issue; Barely noticeable except the puff of smoke. The problem comes when I hold the throttle constant. Ex: When I hold it at 25% throttle the boost will steadily climb from 0 to 17 then jumps straight to 36 and the power comes in hard. I don't like the way it does that at constant throttle. I'm not sure if this is something I can tune out, or of the tuner can work on it.

 

More to come....

My TS Mvp has that same jump in power at 6psi. That seems to be the spot the canbus fueling starts but obviously half the go-fast your truck has

Got some more updates.

 

The 17psi fuel bump has been fixed! Between the person writing the code and my settings on the quad it now smoothly transitions into harder fueling. When at WOT, it still gives a slight puff, but I'm not worried about that. Overall I'm very happy right now. The person writing the code might have some updates for me that could make things even better. I'm hoping to get some videos of stock tuning, old quad tuning, and the new stuff. I think you guys will be shocked at how clean 300hp sac injectors can be!

Lvl0 OEM fueling curve

 

 

 

 

lvl3 which some rough tuning done to lower fueling at low rpms  

 

 

 

 

I wouldn't say the truck feels any slower, this is likely due to being able to use more APPS input and not having to feather it to keep smoke down.

Stock is DIRTYYYYYY!!!!

I dont know how Tyler is liking the most recent release , but I am VERY happy.   

 

No more smoke due to high tps at low revs / boost, no more rolling into the throttle to get the truck moving.  I used to have to step up my throttle from 0 to 15 to 20 to 30 in 1 second intervals, now I just put my foot to %30.   If I would have done this before it would have smoked, now just a very faint haze.  

 

the fueling maps tyler and I have now are pretty relaxed, but I honestly don't notice much difference in smokeiness between the aggressive tunes from before, just a more controllable upper end  

 

My tune starts at about 80% then 88% my 6 psi, then %100 at 10 psi then leveling off to 110 by 17psi.

More testing and tuning

 

Happy to report another day of improvements for my tuning, tyler hasn't gotten his hands on this release, but I am very happy. 

 

I got a chance to do a 0% throttle to %60 and above from a stop up and hill merging onto an interstate

 

Might be a bit hard to see, but I went from 0% directly to %62 and held at ~%70 throttle.......Note when I let out of the throttle due to coming around the turn leading to the onramp., which is fine and dandy, BUT BUT BUT....  not one ounce of smoke.     And I don't mean once the turbo was lit.........I mean from a standstill to high TPS not one ounce of smoke, not one ounce when wiretap came on, not one bit of smoke.    I can't stress this enough, right now I could take my truck into the emissions place and pass with the tuner turned up 

iQuad-2016-07-31-04.54.491189992457.csv is the data log for the run. 

 

 

 

For a comparison, I went from this

 

 

To clean

 

I should have gotten a video, but I was not expecting to be able to do the run.  Egt's are the same so I am assuming that power is about the same.  My butt dyno can't tell the difference.    There might be a second more lag or so, but I am really not worried about it.   I am sure I can add a few % across the board and get rid of the lag.

 

It is hard to tell the difference in power because before power would hit hard, since the turbo was being flooded, now it ramps up very smooth.

I am very happy, but I've got to mess with the setting a touch and see if I can make it even better.

 

As of right now, I can put my foot on the floor from idle and if the boost stays below 20, I don't have a lick of smoke. The only place I'm getting smoke is 22-27psi or so of boost. That's because the boost on these twins ramps up faster than the refresh rate, effectively jumping the fueling up faster than I'd like. I think I can change some values and make it cleaner though!

 

My tune starts out at 68% from 0-2 psi, then ramps up 1% at a time for each psi. Mine is setup a bit different though.... I've got % control from 0-30psi.....

alright got a video of my 0-100% throttle snap with the canbus fueling settings.

 

 

Pretty cool. 

 

1200us seems so short! Stock on a 3rd gen is about 2000 and a big tune can push 3000, and the pressure is higher. I wonder if the injector holes are bigger on 2nd generation? But that would decrease atomization. 

 

Tyler, did you ever get a Pro dongle?

@Me78569 can correct me if I'm wrong, but I think that 1200us is on top of stock. Not exactly sure. I know what you're saying though  my brother's max effort tune is just over 3000us at 22K psi.

 

No I haven't.... my brother and I are in the process of trying to buy a business, so our funds are heading into purchasing that. Maybe after the deal goes through I'll hit Gecovey Coffman up again.

That makes sense.  I haven't found a us reference table in Pro but that could just be what quad is doing. 

 

Turn your brothers pressure up and his duration down :-) 24-26K and 2500-2700us will likely make similar power with better timing and lower EGTs. 

Yes it is fueling time on top of stock. 

 

I am going to put in a map smoothing function to get rid of the psi jumps when at low psi.

I've been fighting with my fuel "bumping" up causing a slight surge in power. I think it's a combination of a bad place to read the boost, maybe a bad MAP sensor, and twin turbos.

Where I was at yesterday, I had the fuel increasing 1% at a time from 68% at zero psi. The problem comes when the twins light the boost jumps from 5 to 20 or 25, causing a 15-20% fuel bump.

This morning I set it to where I was at 100% fueling by 10psi and it seemed to smooth out the bumps, but it's slightly bumpy still. More playing to do....

Thanks for the details that helps  alot.  Specific psi's is important.  

 

I think most of the surging, if I can even call it that, is due to the boost reading like it is.  I might relocate my sensor.  

I have an idea....

My fuel pressure sensor is sitting in my intake horn. Can the quad be made to use fuel pressure instead of the MAP sensor to control fueling?

scale for the sensor is off so nope.  It needs to use a 0-62 ish sensor from 0-5v haha

I have a boost bolt I can just put my oem map into

Ugh... it can't just use the value spit out??

Zeros and ones! Zeros and ones!!!!!!
