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

My truck doesn't show increased boost though, it's only on late model trucks.  

 

The sensor on the late trucks don't seem to account for baro.  how does one resolve that if there is no baro sensor haha?

Colder denser air could account for the difference say if a turbo is spinning at 1000 Rpms at idle in 80 degree weather right now say we cool the air to say 20 or 10 degrees  for the given turbo rpm because it's going to drag in as much air as it can at a given shaft speed wouldn't that density change change the pressure in the intaketract in theory at least to an electronic sensor these trucks have cooler egts and faster boost in winter in my experience so I'd assume u could be making 2lbs at idle if the air being sucked in is dense enough

 

 

 

Uh... No. I'm looking at 2 gauges and my ISSPro shows exactly 0 PSI. The Quadzilla shows 2 PSI at idle. I'm sure I could hook up my old DiPricol boost gauge and verify but there is 0 PSI at idle. 

 

Regardless PSI is PSI. If you have 2 PSI at -30*F is still 2 PSI at 130*F. Colder air density has nothing to do with the measurement. Pound per square inch is exactly that regardless of the temperature. I know @ISX years ago did the math on the air density and what came out of it was the difference in moles (or molecules) its very tiny difference nothing a boost gauge would ever see from temperature to another. As for the sensor reading I know there is a difference for the late model truck as @Me78569 and myself have been playing with this for a while with the OBDLink data as well.

Issue is that the quad is reading PSI from the ecm directly at PSI levels below 16psi. 

 

4 months ago we did testing and found the current calculation shows 0 psi at idle, then a few months ago, nothing changed, all late trucks are now reading 2 psi at idle...    I can very easily adjust the calc to make it 0 at idle again, but I am betting it will then be a delayed psi reading like before the change.  

 

What this means is the ecm is seeing psi in a manner that is causing it to report psi differently now.  

 

The dipricol gauge is self contained and taking outside changes into consideration when reporting boost.  

Well see... Spring is around the corner. We'll see if it continues or returns to zero.

Now if you really want to get confused about it, 2 trucks at sea level and 7000' both reported the same map reading offset, of "11" why 11?  I dunno.

Mine is still reading zero, but I am at altitude... idk what is up.

 

If I had to guess, it would be "better" to have a -2 offset during the summer because warmer less dense air will make it smoke a touch more. Then again, having it at 2psi during the winter doesn't make it smoke because of the cool dense air. Potato Patato

I know I have said it before, but I think the coding is "done"  @TFaoro happy so I am happy haha.  anything beyond this will likely be proof of concept, don't run on the street type stuff.  

 

I wouldn't go quite that far YET... I've been busy the last month setting up and running a business that my brother and I bought. I have a few things I'd like to see improved, but we'll get there. 

why do you hate me?    all your ideas turn out great though, so I am all ears. 

 

 

as to boost I dunno really,   I will look into it more once things warm up and we know one way or another than it is x, y, or z

I just like to keep your mind working  

I sent you a text. I have some interesting info on HO trucks too. It's definitely weird.

Please do tell on the HO trucks. Inquiring minds want to know.

I'll be driving the truck tomorrow, so I'll be able to see what it's doing, but for now I know at idle state the ECM is kicking out about 1* less timing than the SO trucks. That tells me the pump may be mechanically internally advanced by 1* as compared to the SO trucks. 

@TFaoro I should have taped the convo last night when you said you really liked the timing and you were %100 happy and I don't ever need to code anything again    Or at least thats what I heard.

 keep dreaming! There's always room for improvement my friend!

I got to say Thanks to @Me78569 for helping me fix my programming screw up. In my hurry last night I manage to cross my TPS values and created a very poor tune that dropped me from my 20a to mid teens. This over advanced my timing and pulled my MPGs way down. So to others make sure of your numbers you enter are correct. 

 

All I can say is D'Oh! 

 

yea don't  mix up your min' and maxes.  I am surprised you didn't have more issues.

Wow I feel less than productive, sorry for the absence.

 

Also I wish I had more good news for you @Me78569 but I'm having trouble with the idle delay/high idle.  So far it's happened to me on at least a hand full of occasion where I would be just pulling up to a light just coming off the throttle and the high idle kicks in almost immediately.  Delay was set at 120 seconds and when it happens the truck is always below the warm up threshold.  I know you mentioned at one point in time that you and Spencer were working on the issue and I thought yall were good but yeah kinda odd.

 

Also I have had two occasion with loppy idle so that's been odd.  I haven't really changed much with my tunes since you last saw them either and again it always seems to be below the warm up threshold and right after pushing in the clutch when slowing down.

 

Just out of curiosity, is the high idle function just using increased fueling can bus in order to bring the RPMS up?  Only reason I ask is because my AC pulls the idle down significantly so I know it's not the ECM shooting for an RPM.  Before with the idle switch on high idle a load would pull it down but it would almost instantly compensate.  Not a problem here but just something I'm curious of.

Yes, it just bumps fueling.   

 

I will look into it to see if anything sticks out.   

I've kind of noticed a funky rough idle this morning on a cold start. Once it warmed up it disappeared. Double check my program setting and nothing stands out. Might be just fluke? We'll see and keep track of things.

If you don't have the quad high idle enabled then the quad isn't do anything at idle state.  TPS must be above 0% for the quad to send fueling commands or it has to have high idle enabled. 

 

 

If you have factory high idle enabled I would HIGHLY suggest not using the Quadzilla high idle as they do not play nice together.

This is how I feel right now.

 

 

 

I have figure out how to hold fueling beyond redline on canbus tuning.... this is on lvl 3 AKA no wiretap, rev limit set at 3500 rpm.

 

Fueling was only about %25 of what it could have been as I didn't want to have something bad happen at full fueling. 

 

 

I am gonna spruce the code up, but I am guessing that a lot of guys will gain a lot more meat over 3200 rpm should they choose to use it.  

 

Bring it!
