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

Question about the canbus fuel level (0-4095). Assuming no wiretap, is this number an absolute value of how much fuel is being commanded? Are there any other factors at play that dictate volume of fuel injected besides the canbus fuel message?

 

For example, if I'm driving at 100 km/h in 3rd gear, overdrive turned off, my commanded canbus fuel level might be 700. Let it shift into overdrive, and canbus fuel might jump to 850. EGT's might increase 150-250 degrees F as well. Logic tells me I'm using more fuel. Downshift and get the RPM's up over 2000 instead of 1650. 

 

Any other factors I'm missing? Does RPM play a roll?

 

Thank you,

It's true the use of direct gear in your case is producing higher MPG's. I see the same thing driving in 4th gear (direct) where the CANBus fuel is lower and EGT's are lower and my it shows as about 2-5 MPG gain. Then shifting to 5th (Overdrive) then the EGT's rise, CANBus Fuel goes up and MPG's are reduced.

Excellent info guys, thanks very much. I wonder if it one could calculate this linearly to compare fuelling in different gears/constant speeds.

 

Example, 600 fuel units / 2000 rpm = 0.3 BS fuel units per rpm.

800 fuel units / 1600 rpm = 0.5 BS fuel units per rpm.

 

I know this is BS math but you see how I'm thinking? The higher egt at lower rpm may however tell the story anyway. I could also probably use the factory mpg lie-o-meter to see the difference in instantaneous fuel consumption. Not an accurate number, but the difference would be useful in this situation.

Like I'm using OBDLink LX for fuel data its not exact but darn close for the most part but gives me feedback from the ECM of the fueling map and how its performing with said fueling and timing. It's at least some data an idea of how things are working.

What is the recommended vehicle to pick from in the iQuad app? I saw your export was experimental, there's a generic 2nd gen v.2.5, a 2001-2002 v2.4, and quadzilla only 3.7

 

Also, where is the apk that has import support? I need a good mpg DD config with my +75 sticks. The default is a little smokey and bucks with very light throttle.

Don't use the quadzilla only profile. That is my test profile.

 

Try a starting point of 95% in the canbus tune and turn fuel load timing to 1*

Hey guys slowly getting up to speed. Got the apk and the downloads figured out from the repository. Have a few questions:

-when downloading a new tune should it default to the 1998-2000 V2.5?

-what version should I be using (1999 cummins)?

-I recently put 315x75xR17's on ans I know the diameter is 107.91in but it will not calculate my "accurate" speed any suggestions?

 

@Me78569I want to try your daily and see the mpgs cause I've taken a large hit Since I'm at sea level with a stock turbo do you recommend 12% increase on can bus fueling? 

 

Thanks gents!

default to whatever profile you like, the 1998-2002 v2.5 should work for all 2nd gen trucks.

 

Adjust the size up and down until you get an accurate MPH, ensure you have gearing set right and trans set right in the settings.  

 

Adjust up fueling at the 0% mark until you are happy with smoke vs power off the line.  I have not noticed really any change in MPG betwen my daily tune and my emissions tune, which is about %10 difference from each other.  Most of my mpg seems to come as a direct result of timing.  Like truck likes to sit in the 19.5* at 65 mpg and 20.5* at 75. 

 

what fueling mods do you have?  I cant remember.

@Me78569 I just figured out how to update my signature. Hope it works now. Also I was fairly certain I has re gears and the tranny figured out but I'll keep playing with it to see if it changes.

 

Default tire size is 95.7 and I upped it to 107.91 with no MPH change from what my speedometer says. Went by a speed trap ans it's 10mph off at least.

are you saying your cluster speedo isn't changing or the mph reading on the iquad app isn't changing?

Edited July 6, 20177 yr by Me78569

@Me78569

"are you saying your cluster speedo isn't changing or the mph reading on the iquad app isn't changing?"

 

theMPH on the quad isn't changing. I know my speedometeris going to be off due to the much larger tires.

 

Thank you I will give that tune a shot!

after you adjust the tire size have you keyed off for ~5 seconds then key back on and see if it is right?  I can't remember off the top of my head if the tire size applies on start or on the fly.

Yes I ran it for about a week now with the tire size being adjusted with no change in MPH on the Quad. @Me78569 I know it's confused because I will be crushing in 5th on the highway but dude to the lower RPM's it says I am in 4th gear.

I will try and remember to take a peek at hte code tomorrow.  

 

 

I'm not sure what the tire size feature is supposed to accomplish, because I can second that it doesn't change the Quad's reported speed. But now I have my speedo calibrated anyway, much happier now.

@kzimmer I was hoping it would compensate my new tire size so I could have a more accurate speed since I don't have the ability to calibrate my speedo at the moment. 

ill have to test it, I might have done broke it in the update to v2 lol

Haha, nah, it didn't work in V1 either. You're off the hook! I asked Quadzilla about this a long time ago, and like all of my other tech support questions, the answer was "?????????".

 

Happy I found this place! Thanks again for taking care of business!

I had a shop in town do it with the DRB 3 tool or whatever it's called. I think it cost me 0.5H labor.
