Next time you get a chance grab one of the V1 tunes and load it up. see if that does it. I have been through the code a number of times now and can't see anything that would cause it and can't reproduce it.

V2 is for 4k now, it's not as smooth as the normal box, but much better than old 4k tune.

150* - 160* is what mine read via IR gun

that's a nice walleye

ill check when I get home

Pm me your contact info and I can help.

hahahahaha. Don't tell my wife that..she might listen.

Fine I mean I didn't wanna post up how sexy I really am, I thought the above as better for the moral around here .

If you unplug the map sensor the truck will struggle to hit 50 mph. nearly all of the fueling tables use boost as an axis for the map.

jag1 has my spot.

Batteries act as a filter test from the alternator itself.

IF the WTS light comes on everytime right away then you are fine. You had made it sound like you had hard start issues when the WTS light didn't come on.

Be very clear, does the WTS light come on EVERY Time you key on? If the truck is warm it should turn off right away, but it still comes on.

in red.

Nope the quadzilla has zero code in it to write to the ecm. One way communication only ecm > quad > vp44. I'll look over the log when I get home. It would be awesome if you could give me lines to start on for each run so I can build graphs. One more question. Tc locked low rpm, when the shudder happens if you lay into it the shudder goes away right away? Also what is your tune starting point? I am sure you posted it but my memory is like a gold fish.

bucking is going to occur too low in the rpm range. To be clear this does not happen on lvl 0?

You want to stick with the SO vp44. The performance pumps are typically a mismatch of parts between ho and so to get higher timing. Your smoke issues sound like they are related to the injectors. DDP's are known to be smokey. As for better injectors there are a number of good builders, but the price depends on the level you want. The smartys bottom end feels fatter because of the way it fuels. The logs speak from themselves haha. I tried the half power mode with the old quad tunes. It was meh at best lol. Just not a great solution, too much fuel pulled. I would try and recoup your investment by selling the smarty, the ddp 120's etc. Get some better injectors and see how you like it. The edge I ran was VERY smokey on sub level 3+ though. It really doesn't take but a % more fuel to make haze tune to smoke. I am really not a fan of the calibrated performance mm3 offering. They really misled guys and we have yet to see any actual info in regards to how it drives. lots of half truths involved with it. We know mm3 is really cool, we need to know how cool it is. Can it make 7 x .012's run clean? I few guys have claimed the moon, but never showed anything after being asked to. Too much smoke and mirrors in the 2nd gen world.

1/3 seconds as data comes in. Your lope at 950 is just he quad turning on and off. 950 is the limit for the quadzilla sending the commands. Your surge issue I am not sure about. Timing and fueling looks spot on for the oem data logs I have. How noticeable is it?

so you aren't running both?

Well I hate to say it but you really need to dump the stack. I won't go into detail as I wrote and article covering it. as for reprogramming the psg to allow more fueling duration. The way the system works, as far as I know, the ecm calculates the fueling needed based on a ton of inputs. It sends out a canbus command in the form of 55 59 20 00 00 00 88 cb 00 00 00 a9 05 22 0d green being fueling command and Blue being timing command. The VP44 intercepts the command and decodes the 0 -4096 commands as a duration of fueling and * of timing from 0* 30*. Oem tuning command for fueling will reach ~3600 at their peak in the 1800-2200 rpm range, then fueling falls off. Canbus tuners will allow that fueling to reach 4095 and stay there throughout the RPM range. That is where that "65 hp" mark comes from. So a lot of tuners "abuse" this fueling command. IE: the s03 depending on the level will max out fueling by ~%25 TPS input. Datalogs: When you stack the Edge on top of it you will just make the issue worse. With the S03 set to sw9 and the edge turned up to 5 x5 you would reach max fueling by ~%10-%15 throttle input. Again smoke is a large issue on bigger injector trucks if you aren't able to control fueling. Hence why the V2 tuning was created for the Quadzilla. More articles: Depending on fueling mods, altitude and driving style you may need to pull fueling commands lower than stock by as much as %30 in order to be smoke free. My Daily driver tune with 7 x .009 injectors has a starting point of %84 of stock fueling duration. Where as the Edge and Smarty will jump right to %130- 150 of stock fueling depending on settings. As for smarty and their mm3 / touch setup. It is very cool, but it still has the limits of the design of the system. You can still only get a fueling command of 4096. Also they have not opened up all of the tables in the ECM. They have given users the ablity to alter the important ones as far as I can tell, but there are a TON of tables in the ecm. If you research what Jdonghue did ~10 years ago you will find 2x 3x of the tables that the udc pro stuff has. A lot of those are not really needed for the normal guy, but just keep in mind that there are much more tables in the ecm. Biggest issue I have with the udc pro is the cost for what you get. If you wanted to have someone do the tuning for you it is gonna run at least $1500 for that "65 hp". You can make the truck really driveable, BUT we have mechanically controlled injectors. You can only do so much "tuning" before the limitations of the injector hole size vs pop pressure show up. IE without jacking injection pressure up ( we can't really) you can only get x amount of fuel atomized efficently at low RPMS through x size hole. I would say it is pretty easy to get 7 x .011 and under to run clean " no matter what" but as soon as you start getting bigger than that it is physically impossible to get our injectors at 310 bar to atomize fuel right offidle. As for Bosch being able to inject more fuel, I am sure they can. I am sure a lot of very bright engineers at bosch choose a fueling solenoid that fit the needs of the pump. The specs of that solenoid's likely state that at 4096 command duration should be %100. So yes I am sure they can fuel more with the right coding, but that would be outside of the spec of the hardware they choose for the pump. This is why wiretap came around; as far as I can tell wiretap will add ~%20 fueling over OEM at max duration. HOWEVER, this %20 is out of spec for the hardware, thus why we know that wiretap boxes can lead to a rougher life for the vp44.

I see it. Line 8200 ish

950 rpm is where the Quad is starting to take over. What line approx are you referring to?

If you could data log the bucking so I can see what is actually happening in the data.
