@Quadzilla Power any ideas on why Mikes setting buttons are so small?

please be nice to me hahahha

you run those ports to your hood stack for regen?

Well that's a hard one to justify, asking someone to try something someone smarter than us doesn't recommend. haha.

Good to know. I trust his judgement more than my own haha. Back into the hole I go Defuel stuff. I did some more testing today with the defuel update. Rather than set defuel at 23 psi ( unrealistic for my setup) I set it at 30 psi. Result was good, I floored it, boost spiked to ~32psi then settled right down at 29 psi and held. While it works in both situtations, 23 psi and 30 psi, you can tell that the quad didn't have to work as hard to keep boost down. You could def feel the defuel happening, but it was not surge-y I do have to say though, if you want to use the defuel stuff, ensure your base tune makes sense for that defuel point, IE don't run a race tune with defuel set at 23 psi.

@Mopar1973Man test the EGT defuel on an open stretch of road. I honestly struggle to hit 1200*f so it is hard to for me test it. However it is the EXACT same code as the boost defuel which I can test and that works pretty good from what I can tell.

Yes it is the standard fuel.

Different tuning though, I can't comment on how fueling does for the comp vs old quad tunes.

@Mopar1973Man Call them. emails get lost in the vast onslot of stuff that comes in, just like posting them here. Do you have the unfiltered datalog for the graph you posted? I need to know the other sensor inputs from that log to know what caused it to kick out of cruise timing.

Speed is very much an issue as it is a trigger point for cruise timing to engage and disengage. The full data log is needed for me to see what varaible is causing cruise to kick out and back in. There are 5 "are we at cruise" checks that need to all come back as yes before cruise will enable. This flip flop you are seeing is just cruise timing being on then cruise timing being off as a result of one of the 5 above checks not being yes. Based on the 3 sensors in your log I don't see anything wrong with how it is working. Cruise state needs to error on the side of caution otherwise you end up with the issue you had a few weeks ago where cruise state would not release. Remember before cruise state would pull down to match OEM timing, but it wouldn't kick out and it wouldn't allow for a wider spread of timing based on RPM. all I can say is contact Quad about the app issue and ensure it is on their list.

I wouldn't think it is a flow issue then.

do you have good oil pressure now?

well it was pulling ~%50 of total fueling to keep me at 20 psi.....

What's load's scale at here? I double you are cruising along with load sub 10% are you? In the graph I see that when load stablizes timing goes into cruise state. then at ~240 load increases and timing drops as expected. What speed and rev are you at on that graph? tps?

Is what I would chalk it up to. verify you have good oil flow beyond that get AFE to get you a new turbo.

I just know that I had a slight vibration in higher gears in the same rev range as a result of a bad carrier bearing. I would assume since the gearing is harder to push in 3rd /4th that you are not getting vibration at low speeds.

@Carbur8tr @TFaoro @Mopar1973Man @Dieselfuture Here ya go,give this a try. It will pull as much canbus + wiretap as needed to keep boost slightly below desired level, It will bounce somewhat around the limit, but for my it stablized at about 20 psi when the limit was at 23. Once it finds a happy defuel amount it will hold until boost falls. Anyways give her a go and let mw know what you think. https://drive.google.com/file/d/0B46GXQ9arT2lUWR6Znk2N1gwbEU/view?usp=sharing

I understand what your saying, but I can't fix the app side stuff, that is %100 outside of my control. Gotta understand I have no dog in that fight, you will have to talk with @Quadzilla Power about it directly, I simply will not remember as I don't have that issue on any of my devices. Cruise timing is %100 controlled by RPM, no reference to boost, no reference on load / tps. Cruise state timing will never increase timing if RPM is stable. If timing spikes then it is not related to cruise state. Cruise state should only kick in if truly at cruise, I don't consider climbing a hill cruise state. I can't make that choice for everyone, which is why the boost limit was put in place. Any spike in power need should kick out of cruise state timing so that the users psi limit can either lock out cruise state or lock it in when fueling stablizes. Keep in mind if you hit a hill your CC increases TPS / fueling, fuel will spike, cruise needs to kick out, timing will drop if boost is below 8psi. the higher tps goes the more timing will drop. I would wager that you are seeing cruise timing disable and that is why your timing increases. at 65 mph / 1900 revs.\ I would guess your base timing is what 18*? Maybe you need to dial back your 2k timing a few * to get what you want? Also again I can't use actual engine load as a tuning variable since it is not reported on early trucks, so keep that in mind when you think through stuff.

@Mopar1973Man That image isn't actually a timing map. look at jdonoghues notes for 2008 with those tables. its actually a fueling table. It also doesn't match what OEM timing does. OEM timing is NEVER high at high map / low engine speed. it only ever goes high at 2400 + rpm and if load is very low. So I know you hate getting Data logs, but I REALLY need them to look at whats going on when you give examples. The way the Quad calculates timing is VERY complex, so I need to know all the sensor inputs at that point in time to truly understand what is going on. So lets look at how the timing work in the Quad. The only time OEM timing is considered now is sub 120* / warmup and below 1500 rpm. During cruise timing OEM timing not considered, There is a bug on the screen display that OEM timing will show vs the actual timing, but this only happens when going from throttle state to no throttle, but RPMS are still up. Still thinking through that one. However the timing going to the VP44 is correct, the screen just isn't showing the quad timing. RPM Timing you set a high limit for an RPM range, then the low limit for that range is taken from the high limit from RPM range before. timing is always stretched between the high limit and low limit, then pulled down if load is low. I know you think this is backwards, but the Quad uses a completely different table to pull timing for spooling the turbo. Fuel load timing is purely for performance state / once boost is up so don't think of it as a way to pull timing to spool the turbo, that's not it's purpose. IE: 1000: OEM 1500: 15 * 2000: 19* 2500: 23* 3000: 25* max: 26* So between 1000 - 1500 rpm Low limit = OEM *********** high Limit 15* 1500-2000 rpm Low Limit 15* High Limit: 19* 2000-2500 rpm Low: 19* High: 23* Etc etc ******So OEM timing might actually be high or low before 1500 rpm. You might see that OEM timing drops to 11* at high load below 1500 rpm, it might also come up to 16 - 17* on light throttle that is why you see that timing down low doing something odd. so pre 1500 rpm you might see a timing amount of 17* even if you 1500 setting is 15*, but as rpm approach 1500 rpm timing will also approach 15*, form above or below 15* depending on what OEM wants. Keep in mind, in terms of timing, the ecm won't fight the Quad like canbus fuel will. The ecm set a desired timing and sends the message out, end of story. The ECM will not try and retard more or less than the table tells it to because we alter timing. I have done a lot of data logging showing Quad timing vs oem timing and oem timing is always the same in similar situtations regardless of what I do on the Quad. Cruise timing no longer fights OEM timing, if Cruise timing is on then you get the desired amount of timing without input from OEM. The bug you are seeing is the screen bug that I don't know how to solve due to your late truck and their electronic CC being a PITA. It is VERY difficult, programmically, to know when your trucks are using CC or when you are actually off the throttle, but revs are high, like engine braking. So lets talk about High load , low boost timing. IE before the turbo has spooled. OEM timing will hold timing down around 11* even as boost comes up beyond 20 psi, Everything I have read / input for other guys say that timing only needs to be low when load is high BUT boost is low. They have also said that the reason why timing stays low is for emissions reasons. You will clearly get more power by bringing up timing once boost comes up. Lots of reports of much better butt dyno feel. So what the Quad does. It has a full timing map for Low boost / high throttle. Has nothing to do with RPM, just tps and boost. So if boost is low and you go high throttle it will pull timing, just like oem, based on your timing reduction timing setting. It will allow you to pull timing down to that 11*, or less, if boost is low and tps is high. however as soon as boost comes up beyond 10 psi that timing retard is no longer used. You will see this in a data log. This is what we want, only pull timing when boost is low tps is high, once boost comes up them timing should come up. IE: Say 1600 rpm RPM low limit: 16* Fuel load timing: 2* Timing reduction: 3* Boost = 2: TPS = going from %15 to %70 TPS so the quad base timing will start off around 14.25* as you are at light load in the 16* range. The Quad is always looking at the Low boost high tps timing table, but it always returns 0 unless throttle is high while boost is low. So as soon as you spike throttle to %70, the timing reduction map will return ~%70 of that 3* and the quad will take that 14.25* we started with and minus %70 of 3* = 2.1* or 12.15* of total timing. Just like you want and just like OEM is wanting. It is impossible to control cruise state using Quadzilla load. It is WAY to dynamic. Even a %5 spike in TPS will cause Load to spike by at least %20. Boost is a much more stable way to turn off cruise timing. Keep in mind that early trucks DO NOT REPORT actual engine load across canbus. So the Quad cannot use it. I would love to hear more, but I will need data logs to show a specific issue.

@Mopar1973Man I wont have time to chat about your findings for a bit here. Post them up and I will take a peak at any bugs.

hows your center support bearing on the driveshaft?

The base tune needs to be flashed by a PC, ask quad to when they ship it, but once that is done then the actual how it drives tune is done in real time from your device. Those are the tunes you see here. The base tune is what allows the new tuning to work, your settings for the base tune are the phone thing. I have 4 tunes right now on my phone, what you see from the video. Daily, %100 smoke free Race much more off line power but does have some haze and a puff from wiretap Tow more meat down low but tapers off up top to keep power low. Stupid, it is what it should like.

once you get your hands on it, it comes together, but I understand. FYI I haven't changed my Daily tuning is well over a month and the only reason I did that was for the new tuning variable for cruise state haha.

Yea there is no replacement for cranking haha.
