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 am seeing that also.  A TON of timing gets added when iat is cold.  Been mulling that over.

 

My last run the best I could do was about 18-19 MPG it's pulling the MPG down hard when you start dropping IAT temp. The only solution I've got is to cut the total timing back even more like 1-2* degrees total. Problem is the ECM is programmed for 40-45 cetane and cranking the timing up. Here the cetane is like 50-53 so the timing is already in the fuel and not required. Bad part is the ECM and Quadzilla can't see fuel changes.

Quick fix would be to build a custom tune for the "Hoth" days with less timing added. It doesn't seem to be very nice to have to switch though.

Do you have an ETA on when the update will be pushed?

We still have a couple of bugs to work out, but it should be coming soon. And by soon at Christmas time I mean like a month from now. 

 

I honestly don't know if the timing even matters when it is that cold.  I doubt damage will happen.  Knowing how the old tunes worked I don't think the v2 will hurt even when it is way cold.  The ecm is asking for %85 of the timing. 

 

 

@Quadzilla Power  I really have to comment on the "hoth" statement....Good work

 

Well,

 

I work up at 3 am with an idea on how to solve a couple of different low level bugs.  I think I have a fix for mikes issue, of warmup mode canceling lvl 1 when set to anti theft, and I think I have a fix for warmup mode if your starting point is under 100%.  

 

If you leave the tuner on lvl1 warmup mode will not engage the next time you start the truck, since lvl 1 can only be subfueling there should be no issue,

 

2nd bug was a bit harder to solve, but if warmup mode is enabled > enable quad's output canbus message + use only boost lvl 0 setting until warmup is disabled,  I might need to add a few lines to this to allow for 0 - 5psi settings to be used, I don't know if 0 psi setting is enough power to be safe.  

 

Regardless I am excited to have those fixed...the latter has been bugging me for awhile now.

 

Bugs are fixed and tested.   I posted them 
https://mopar1973man.com/topic/12025-how-do-i-manually-install-the-quadzilla-driver-load-the-quadzilla-v2-tune-on-windows-10-8-7/

If you leave the Quad on lvl1 warmup mode is disabled, if you have a fueling start point below %100 then that is used until warmup is reached.  

Spent some time tonight messing with idle state fueling only to find that if you remove fuel at idle the ecm just adds it back to keep revs.  

 

As soon as you say "screw you ecm" and just set an idle fueling message the vp airlocks when you let off the throttle coming to a stop....stupid truck.

Nothing in this life is just is, everything has its reason and leads to something.

Just catching up on the thread, I love it.

 

It sucks we cant override the Idle fueling to set a custom Idle RPM.

I'm glad we can't change the idle. 800 RPM's is awesome for creeping in snow. 

in theory the ecm only fuels enough to keep revs at 800, so limiting fueling at idle would do nothing to help guys with firehose injectors.

 

really just an excuse for me to whip out some code.  

 

Thanks to Tyler I also have some pretty cool new code   Just another step towards more timing control.... ALOT more.

Hopefully the timing does what I want it to! Ready to test it. I will have a PM to you in a few minutes.

I might also have an anti stall function ready to test 

So on the timing control note, have we figured out how to maybe limit timing in cold weather to prevent spikes?

 yes  

I've been driving a car again instead of the truck and I think I forgot everything that I learned plus you guys keep coming out with new fixes. I'll have to learn this thing all over again.  hopefully it will all be ironed out soon and have clear instructions on how to.

Unless you want the new fixes I wouldn't worry about it.  I doubt the public will see the really neat nerdy stuff, those are more of proof of concept, maybe v3 tuning down the road who knows.

@Carbur8tr @tfaoro @dieselfuture @mopar1973man @xxtjrocksxx

 

 

How big of an issue is the off idle lul that happens?  Do I need to create an "anti stall" function or do you just get used to driving with more throttle and not think about it anymore?  

 

I am REALLY struggling to come up with a good solution for an anti stall.  

Edited December 28, 20168 yr by Me78569

??? Not sure I've noticed it much at all.  Are you referring to the truck trying to stall off idle rolling into a gear?

Yea

 

since we are reducing the fueling message at 0 psi you will see that off idle fueling may be too low, but good once rolling.

 

IE: say idle is 500

 20 mph cruise, 0 psi, is 1000

 

Now we take the quad tuning at do %80 of fueling at 0 psi.

 

So offidle we are left with 500 * .80 which is 400

cruise we have 800,

 

the %20 reduction in fueling is more noticeable offidle.  

 

auto trucks don't seem to care due to the converter, but manual trucks seems to have a lul offidle.
