I would call Edge and see if the box can switch between the sub generation. it is more complex than a resistor. the entire map offset is different and no linear in any way shape or form. I would also buy adapters from them if possible. As soon as you cut the harness it is effively worth nothing if you try and sell it.

oh man I didnt know you still did that???? I was gonna dig into the obd stuff using terraterm, but I mean if you already did.

First thing I am working on is obd stuff and PID's there is a ton of data to look at.

I wrote pretty much all of the V2 update. There is only 1 map that the quadzilla uses, which is wiretap. I spent a good bit of time working through what an IAT map would look like, but the resulting alterations I did not find useful and the general though from people was that there was enough tuning variables as it was. The canbus fueling is all a push or pull of the oem command. The oem maps are really nice and really smooth, no need to recreate them. It is a piggy back box, the ecm looks at sensor data and spits out a fueling command, then the quad grabs it and changes based on boost and the setting in the tune. For Timing the quad waits until ECT is above 120*f then it ignores the oem timing map and builds 4 different 2d maps based on various sensor inputs. It then looks at an overall state and overlays the 2d maps to create a sudo 3 or 4 d map if that makes sense. The issue with creating a few 3d timing maps is trying to have the end user alter that many data items wouldn't work. The OEM timing maps leave a lot to be desired as well so we couldnt really use them and still have people "tune". That's not what the market wanted. This method is not as exact as the udc pro type tune, but it is much easier to build and more forgiving for a novice. The resulting tune is still very good. There is also an easy tune method built into the Quadzilla timing function. If you leave all timing inputs set at 0* then your sliders will be an OEM + what you want in the slider. I dont like the resulting timing curve much, but some guys use it. the 2nd gen world is correct for a piggy back system, the CR world is not. The ecm in the 2nd gen truck is built in a very restricted manner that you have to play within the limits of the communication protocols in place. That is why the piggy back is useful. That 66 runs REALLY clean for what it is. Good work. Share the tune? I know a lot of guys with 66's would love to have theirs run like that.

fixed that for you.

I used 7 x .012's because I was developing the v2 tuning and wanted to know how far I could push injectors with a small turbo and high elevation. AKA trying to create the worse case situtation and still have it work. that way I would know if the project was possible to get done with good results. there is no IAT related map in the Quad once you are up to temp, much like the ecm, IAT is largely ignored ( unless temps drop below 80*f) There is the code in the quad to do it, but we never got a good train of thought in terms of how much offset to use for what drop or rise in IAT temp. injection pressures are not fixed in the vp world. Pop is set, but you will see a step rampup of nozzle pressure up to 26,000 psi or something like that ( dont remember anymore) every stroke. the 7 x .012's ran the best out of all the injectors I have run actually. they had the best mpg, even at stock pop. however I learned a lot about what my truck liked for timing when I had the 7 x .012's I never got that chance with the 7 x .009's or stock. Using short duration and big injector opened up a lot of the duration map to play with though. as for good mpg, it really all came down to hitting that 19-21* mark at cruise state.

lift pump always as your lift pump is pro no putting out anywhere near acceptible pressure.

We are picking up the truck tonight. Report back from FCA was " it might have gotten hit with hail. it might have been repaired, but if it was then it was under 2k in damages and we don't report to you or anyone in that case. if it was repaired it was repaired to new truck condition." I dont think it was hit given the amount of dirt on it when I seen it first. there is no way it was cleaned and fixed( they wouldn't have worked on the body / paint without cleaning) and ended up as dirty as it was. If we would have not asked for a status update 2 weeks ago this never would have happened as no one outside of FCA would know about it. regardless whatever.

vp man vp, they are freaks

My old truck was 7 x .012 injectors set at 330-350 pop depending on the set I was testing. he351ve turbo with my programming 4" exhaust. pureflow pump with filters, then the typical 450 hp trans build, 235/85/16 tires on 16" steelies with 3.55's. at 55-65 mph if I stuck timing at 1-20.5* of timing I would easily do 22-24 mpg. if I stuck to 55 and really tried I could hit that 25-26 range assuming it wasn't windy. the 330 pop injectors did really well on mpg. oh yea, and dents lots of them.

you just choose the v2 vehicle profile in the app once the box under the hood is updated.

We would love to hear it.

I got word from the dealer yesterday that I can buy the truck, but still no offical message from FCA about what actually happened. I want to make sure I dont have something pop up down the road to kill the value of the truck.

Nope. Idle state is untouched

Yep

go anything with the wastegate to increase boost?

Remove the boost fooler. It is effectively telling the quad not to fuel. Jhook the wastegate Then prepare to buy a new trans

that's why the ad says it didn't drive. They were scared to.

haha thanks, but 14.9 is good enough to make the monthly fit within the budget.

hopefully tomorrow that will be resolved. Only bad part is we are only at $14900 down payment. We were at $15000, but spent some of it to paint the bathroom when we heard we had to wait for another truck lol. 14900 isnt a big deal, but 15000 looks better on a check lol.

stock turbo is a 56 inducer so a 62 is a pretty big upgrade. 12v have a ppump which can easily fuel to 4k rpm. 24v make their power from 2000-2600 rpm

vp trucks are very rpm limited, you get a lot more useable torque from a 12cm housing on a vp truck. not 12 blade 12cm ^2 exhaust housing.

If you want 500-550 hp then I would choose the 62/68/12 VP trucks do much better with a 12cm exhaust rather than 14.
