That's a tune issue and not related to possible efficenty. The edge being on level 3 is adding a good bit of duration on top of your mm3 tune. Having datalogged the edge's lvl 3 stuff I know why you have over fueling. Bigger injectors allow you to run less duration and make the same power. 125's are not big enough for that turbo. what happens is you end up with an aggressive tune to make up for the lack in the injector's ablity to flow fuel. Smoke and heat are the result of that. Since you asked for our opinion. if it was me I would ditch the edge, run only the mm3 and get your tune sorted. If you are unhappy with overall power at that point then injectors need to happen, not more tuning. That 63 turbo should flow enough air for 7 x .011 or 6 x .013 injectors. your injectors are what most guys run for a stock to ~60 mm inducer turbo. to get on top of that turbo your tune has to run a ton of duration and even then you are really not pushing the turbo. Mike is running bigger injectors with his much smaller hx35/40 hybrid.

so fuel is injected over time. During that time the engine is spinning, the point of rotation related to TDC changes throughout the injection event. The longer you inject fuel the more the engine has rotated. As you reach the extremes of this you start to have a less efficent burn. VP44's and wiretap happen to have a HUGE change in the rotation angle related to TDC when you are running your tuners on " kill" . I am pretty fuzzy about this anymore, but I want to say it was something like 80*-120* of difference in the point of start of injection and end of injection related to TDC. You would have to do the math, but it was a lot regardless. CR trucks use no where near as much duration as VP trucks do because they are much more efficent at injecting fuel in terms of MM3 injected vs time. Edit: found it at 3200 rpm with full wiretap and full canbus the vp44 tuners command an injection event for 96* of rotation.

Wiretap can get hot regardless because it makes it so fuel is injected over an EXTREMELY large angle of rotation. I read the math somewhere at some point and it was crazy long amount of angle of rotation.

I would say you need bigger injectors for that turbo. 125's are better suited for stock to mildly upgraded turbo. a 63/91 is going to need some fuel to get going. I wouldn't hop off the mm3 yet as the quad will still prefer more fuel. I'd be looking for some 7 x .011's or even 7 x .012's and proper tuning with the mm3. heck even some 6 x .013's Makes sense why they wanted to stack the edge as you need a ton of duration with those small injectors to get that turbo going. rather than stack and run duration through the roof you should use bigger injectors and less duration.

Agree'd a piggy back system is not as desirable from a technical standpoint. things would look a lot different if MM3 came out for VP's ~5 year before it did. Comparing the Quadzilla to mm3 is like comparing apples to oranges. They are both tuners, but different goals, and different expectatins.

It is, I wish the vp world didn't get it last as it was already to late for it to be popular. The quadzilla solved the bulk of the custom tune need for the vp44 masses, but it is not the same level as mm3. The Quad was designed with a different goal than full custom tuning.

~60 hp on stock injectors. I like to say %20 over stock tuning.

Quadzilla adrenaline

Something at gets timing at or near 20 * at ~60-65 mph.

no wait to start means the ecm is not booting.

pretty sweet setup. @AH64ID got any tips for the tuning on the 6.7?

Try and reflash because the code does not allow for high idle to be enabled when the power bar is red

the code only allows for lvl 0 warmup mode OR if the bar is green. If it is happening on red then it isn't warmup mode causing the elevated idle.

Quadzilla high idle only worked on lvl 0 within the code. Or if the power bar is green for being colder than warmup temp setup.

Don't put too much thought into the gear selector. It is a best guess based on math. There is no trans sensor information to read in regards to gear on the engine bus. Please datalog the high idle issue happening.

I would just tell them you don't want to stack tuners. The mm3 custom tuning should stand on its own. OR the edge should stand on it's own. "whats the point of a custom tune if you are just going to put a boxed tune on top of it?" take the edge off and see how it runs without it. If you want more power then either, run the edge without the mm3 tunes or step up injectors and use the custom tuning mm3 provides.

What size turbo? Yea if you paid $50,000 I would ensure you get a good tune.

What size turbo? 125's are really not that big for most aftermarket turbos. Generally speaking 7 x .010's ( 150 hp) injectors are about the smallest you would go with a ~62mm turbo and 7 x .011's when you setup up to a 64 ish turbo. Sounds like alot of $$ was put into this.

Turbo?

They don't have the edge maps, I was just making a point. Edge isnt going to send their maps out, that's their secret sauce. I dont know what mods you have but if I was you at this point I would remove the edge, drive the truck with just the mm3 tuning alone. If you are unhappy with how the truck drives then have the tuning changed. If you are unhappy with the power then bigger injectors are in order. Stacking the edge on top of the mm3 is just not a good idea. You might as well just run the edge solo.

Just understand that the mm3 tune is the "base" however the edge is editing that tune based on the internal maps of the edge. You are using the mm3 tune, but the edge is altering the commands to the vp44. You can't really know what part is the edge and what part is the mm3. Neither does the tuner, unless they somehow have the edge maps to reference. Which is doubtful. I just want you to be educated about what is going on. Think of it this way, the mm3 tune is outputting fueling and timing commands to the vp44, the edge is intercepting those commands and adding to them by a factor that is dynamic based upon the maps. IE the mm3 tune might be calling for %50 duration ,but the edge says it should add %10 on top so your total output is %60. Just keep in mind that things like RPM, load, boost can all change the location in the map of not only the ecm tune, but the edge tune. It is impossible for the tuner to say " I understand what the edge is going to do so I make my mm3 tune work with it" I am sure that is what they are going to say. Main point doesn't change, though if you have a custom tune why do you need the edge? Wiretap is great, but not worth it if it means you are altering the custom tune you paid for. There is no way to tune the edge into a wiretap only tuner.

have you removed the edge yet and just ran the mm3 alone?

Don't know, However if you paid for it I would get your money worth Tell the tuner you dont want to stack the edge and to make the truck run well without it. Mm3 isn't widely used enough on the vp's for me to have a recommendation.

remove the edge and get the truck running well with only the mm3. You paid for a custom tune you should get a good tune.....
