It's both frustrating and a tease at the same time lol. Dammit Simba get sober so that we can destroy stuff in a coherent manner!

Android tablet arrived and I installed the quadzilla. I have the stock file in the ecm right now but still have the mm3 wired in (although not the datalink) so that i can and/or clear codes if need be. I've been through a couple threads relating to initial settings for the quad but have been timid in regards to actually making a baseline tune. I read that a camera is helpful so I installed an aftermarket camera at the top rear of the cab, and then used a suction cup mount to place my GoPro on the passenger side of the bed to get a comprehensive view of what's exiting the exhaust. Given my list of mods, any suggestions for initial settings? To give a picture of fueling, at one point (before I installed the quad) I set the mm3 to lvl 4 and comp box to 5x5. At these levels and the water/meth dialed in running 60% methanol 40% distilled water, the turbo almost instantaneously ramps to 45psi at any rpm above 1400 and there is SIGNIFICANT amounts of extra fuel. Also at these levels, the bucking that is present around 2000rpm seems to disappear, but at any other lower setting, the bucking returns. I think it would be accurate to say that this engine is capable of insane numbers, but I'm missing correct tuning due to my own lack of knowledge. The best I've gotten on a dyno before the quad, is 2100 ft/lbs, but I'm infinitely positive that there's more there because (even though I'm a newb and have a library worth of things to learn) I can tell that it isn't running at a point of maximum output or efficiency. When I really got into the fun pedal, it just acted like a lion trying to break out of a chicken wire cage, but the lion was drunk..if that makes sense.

Batmo-Ram?

Still waiting for the android tablet to show up so that I can utilize the quadzilla, running stock ecm right now, she's smokey but i finally ran through all of the Snow Boost Juice in the 10gal. reservoir and got to start playing around with the mixture. 60% methanol and 40% distilled water seems to really clean things up at the exhaust pipe. On a lighter note. In Illinois (i work in Chicago but live in Indiana ie no diesel emission testing) it's temporary state law to have a covered face in public....lol, ok game on.

I haven't had an issue with changing tunes on the fly.

It's RTG in the mm3 UI.

Just got an email from quadzilla and the tuner will be here on the 5th, so I'll be able to further diagnose/eliminate variables when that arrives. Until then I'm not going to take any unproductive risks and just drive the chopstickmobile (Hyundai rental car). On that note, any recommendations on numeric Android version and/or tablet to use with the quadzilla?

Ok ok I'm starting to see where this might be coming from. So instead of replacing apps first, what i should do is quadzillafy this thing first and if the issue is gone like yesterday then it would be reasonable to say the table was altered. If the apps voltage is scaled on a non linear curve by the programmer, would it be possible to say that is also what is causing the bucking around 2000rpm regardless of tune level but not present with stock ecm file?

When you say messing with the table. Do you mean being able to adjust what is seen as an output or that the voltage actually coming out of the apps is wrong? If being able to alter what the ecm is seeing in terms of apps voltage is possible with the mm3, it would completely make sense why it's not acting up on level 1, but on all others.

Could electrical "noise" be a possible cause?? I used self vulcanizing rubber tape from TPC Wire on battery and alternator connections to try and eliminate that as a variable but maybe it's possible from somewhere else??

Right! It makes no sense and then gets even stranger when the code isn't present on level 1 but all others.

Hey all, sorry about the delayed update, took a little longer than expected to come back from the dead due to getting serial murdered at work. So. Drove a 35 mile loop again with stock ecm file just to be certain i hadn't missed any detail or variable and also in the hopes that the apps would act up thus making this an easy fix. Not a hiccup to be had (plenty of smoke though). Reflashed the ecm with the mm3 program and went on the same loop. Bucking still present with all 4 tunes. No tps issues in level 1. Levels 2, 3, and 4, tps code p0121 every time upon loading engine regardless of percentage of throttle. Clear everything and recalibrate apps. Plug data link into comp box (mm3 on level 1), p0121 every time engine loaded regardless of comp box setting. Remove comp box again, recalibrate apps, re run loop with mm3 flash same results (no p0121 in level 1, present in all other levels). Return to stock ecm file, no p0121. At that point I'm full level Curious George and get out my multimeter. Resistance to ground is infinite with appropriate wiring (thank you mopar1973man for the wiring diagrams!) Not being satisfied, use a megger to insure insulation isn't compromised, no issues. Check and recheck dc voltages using a UL certified 12vdc power supply as reference voltage, everything correct... It's an entire season of LOST goin on over here now. Ordered an apps from blue-chip, and still waiting on quadzilla to arrive. I guess my plan at this point is to replace apps first and see what happens. Quadzilla is going in regardless, but first I want to see where all these shenanigans are coming from.

I'll flash the mm3 back and drive to work tonight and post the outcome. If it does come back I will double triple and quadruple check all the wiring to be certain it's not related to a deficient reference, ground, supply, short, etc.

But the curveball in the edge being the possible culprit is that I ran just the mm3 and these issues were present. The edge was physically gone from the truck during the very last attempt at this before restoring the stock ecm file. I guess to clarify, was it possible that physically removing the edge, trying to drive it (i.e. introduce a time span of engine vibration after possibly jostling wires) could have been the reason it stopped acting up, rather than removing the mm3 programming curing the issues? Once again I apologize for my newbie-ish ways.

Hmm. My brain is really upside down now. Removed the mm3 tuning altogether and the comp box. Running the stock ecm file, but still have the mm3 in the obd2 to monitor parameters and see/clear codes if need be. The truck definitely runs smokey, but no bucking around 2000 rpm, and no tps codes... what am I missing?? and yes the truck ran cleaner and weaker with edge removed. I've got to be missing something dead obvious if you're saying it's not a tuning issue. Literally the only "hardware" I touched was removing the edge. Software I just returned to the stock ecm file, and now those 2 issues are gone. Longest stretch for a reason I've ever made in my life but, could I have possibly inadvertently jostled a wire while removing the edge and such??
