Nope not enough hands

You can't put load on the engine enough to build boost without roasting the clutch. It will in theory work, but I am guessing your clutch will be smoked before you launch.

stop deleting it lolol or go to your good willnext time and buy the cheapest windows xp machine you can find. $25 and done And here's a GREAT FML moment.... lol green is what is added, red is removed. Thats ADR1000 vs current V2, and that's only the fueling and timing logic. none of the communication code

Flash with the version I posted this afternoon 2.7.6. The high idle state was looking for speed to trigger, but not to cancel. Kinda the same logic as the high idle switch not canceling. I also fixed the jump of rpms. It doesn't jump on my truck let me know what happens on yours. IT also has yet more improved fueling handoff between the quad and ecm.

No clue, my truck doesn't have TM so I can't tell you how it interacts. Throwing the canbus at %150 across the board and a ton of wiretap will try and overwhelm TM, but the longer you spend in the 1 -25 mph area the more tm will pull fueling.

If ( mph == 0 && boostdefuel == T) then if ( boost < boost limit) add fuel if ( boost > boost limit) reduce fueling so really you plant your foot to the floor because you know you are going WOT leaving the light. while mph = 0 the quadzlla will manage fueling to try and keep boost as the specified amount.

It's a no warranty on drivetrain parts type of thing. I know the code works haha.

So is there anyone with an auto that wants to test / use some staging code? I ran the testing awhile ago at 5 ish psi and it worked pretty good, but my drivetrain really can't handle 15 psi launches. the code will manage fueling to try and keep boost at X if mph = 0. Pretty fun.

I reran the idle test with the stock bar injectors, I wasn't happy about the 120*f+ difference in egt in the logs it was too much to be correct. this time the average egt was ~50*f more with 305 bar vs 330 bar, which is much more acceptible. weird thing is we see that 50*f difference in multiple steady state tests. Rest of the stats are nearly the same. Results are nearly the same. Conclusions are the same when I compare the 2 sets of injectors.

lolol 250 psi is 17 bar. bosch says that 310+17 is within spec.... so I guess 327 is the limit lolol Id put them at 315 bar then

My theory is as injector size goes up pop pressure can be increased without neg results by more and more. 7 x .0085 I doubt you would gain anything honestly. I dont think I would personally mess with pop pressure if I was you. If we say that 7 x .012's like 330 bar ( still hard to say that) and stock 7 x .007's are at 305 ish, then do a fuzzy math increase then you are looking at 310 bar or something for 7 x .0085

This morning was the first cold, 7*f, morning with the stock bar injectors. I can say that the 330 bar injectors started WAY easier, the truck was about as angry as I have seen it this morning. The 7 x .009's acted about the same at -30*f. injectors are back off to DAP to get repoped from 330 to 350 bar.

I dunno why I didnt think of this before, but @Carbur8tr asked if I had idle state data logs to compare. That gets rid of nearly all variables. Each log is pulled from 0% tps, 0 mph, same IAT , trans temp warm , warmed up engine, and in gear after ~20 seconds of sitting in that condition. EGTS are stablized in both IE: we are not seeing an idle from right after a hard pull or coasting to a stop. These are true idle state in gear. First the graph Again most noticable is the diffence in EGT temps, the 330 bar are noticable cooler. also note how stable the 330 bar load line is compared to the jumpiness of the 305 bar load line. This suggests the ecm doesn't have to work as hard to keep rpms at 750. Here's the data showing averages from the idle. 305 bar is highlighted in grey First thing I see again is the difference in EGT temp. a full 52* cooler at idle for 330 bar. Dunno why seems like a lot. Next is the difference in fueling duration at idle ~%2.05 higher with 330 bar. this means that in theory the 330 bar inject ~%2 less fuel per the same duration command under the same conditions. the next thing I notice is in the data itself, the 330 bar injectors seem to idle smoother, the ecm does not have to adjust fueling as much, note the fueling spikes in the 305 bar idle from 800 up to 1100 and back down. I feel this and hear this as well with the 305 bar, they dont idle as smooth. you can see idle is more steady with 330 bar if you look at the min = 1000 and max = 1098. I think it is fair to say a little extra pop pressure results in a smoother idle with the 7 x .012's I have. I also think it is fair to say that the actual fueling difference between 330 and 305 bar is negligible. If we compare 0-60 times, idle duration, cruising duration we keep seeing the same thing. So the real question is, given the negligible difference in fueling reduction going from 305 to 330 bar, is there a perk to upping pop pressure? I am still not really sure. If I watch the videos over and over for the 0-60 I see less smoke in the 330 bar, but that is my eyes. i am getting excited to test the 350 bar. Pop Vs Timing Talking with @Carbur8tr I dont even know if the overall time of combustion is changed by increasing pop. We know the start of injection is later, but the end of injection is also sooner as a result of the injector shutting sooner. So the overall time is shortened for the fuel being injected, but the vp44 is still injecting peak pressure at the same point as it was before ( due to the cam ring design). So what about the point of combustion, does that actually change as a result of higher pop pressure moving the injection event a meaningful amount? Or does the fact that the peak pressure point of the injection cycle is the same mean that the combustion point is steady regardless of pop pressure and we are simply injecting less fuel? What say you @AH64ID you have a mind for this type of stuff. Does increased pop actually change the point of combustion IE does timing actually change due to a mechanical difference in the injector pop?

nice looking tune. I like to see people setting their 0 psi setting higher than their 1 psi setting, good work! once you get a bigger turbo and studs then we can play with things more. You will gain a TON up top by adding timing. 30* by 3k rpm is pretty typical for boxed tuning on our trucks. The slushbox makes it nice for the 0 psi setting I dont have to worry about that bucking, my starting point for the tune is %65.

Nope, that's not how the hand off works. So when you start the truck the quadzilla sets the handoff point at 1000 rpm and tps > 0. once 1000 is reached the quadzilla will hold onto control of fueling until either tps < 1 or rpms fall below 700 rpm. Once either of those happen the handoff rpm is set back to 1000 rpm and the cycle repeats. This way you dont get a fight for control once a condition is met. that loping you see in the datalogging is %100 the ecm trying to manage engine rpms at idle state without load. It shouldn't die if it does regularly I would be looking at your injectors or pump. If you want to help your offidle power you need to make sure you are setting you 0 psi setting high enough. It might be needed to set your 0 psi at say %70 but your 1 psi setting at %65. Easiest way to know is set your quad to lvl 1, then adjust you valet mode power until you are happy with the offidle power vs smoke. Once you find a good % for lvl 1 to feel good then use that as your starting point for your actual tune.

yes, that setting will vary for each truck signficantly moving down the road. It's really just a % used of possible power. My truck has a much higher possible power level than yours so my % for cruise state will be way lower.

it really depends on your injectors, Engine load will be significantly reduced as you climb in injector size. On stock injectors %35 is pretty typical. It's not really a safe vs not safe in this situtation. Say Mike needs 100 hp to move down the road, same from your truck, same for my truck, but the duration command will be %35 on yours %25 on his, and 15% on mine. same power to the road.

until you slap another turbo on her

You can create charts using open office or libre office, both are free. I use excel because I have it. I would just say your timing differences are IAT temp related, you will have to datalog to confirm, but it sounds like typical behavor.

I dont like the idea of a computer driving me around BUT humans, in general, are far more likely to make an error in judgement based upon something like I am late or passive aggressiviness or looking at a pretty lady. I would wager every ounce of money I make in my entire lifetime that accident rates would go down if all cars were computer controlled. Sure there would still be accidents due to computer error, but there would be far less computer controlled cars reading text messages. Good drivers these days are far out numbered by bad drivers.

Idle timing is largerly based on IAT and ECT temps. are both sensors working %100? 15.5* of timing at idle tells me that either the truck is cold during these times or you have a bad sensor.

we just recently found out.

Samsungs have an awesome "feature" that dont allow you to import tunes. I know quadzilla is working on a fix, but until that point just input them manually.

You can enter tunes from this thread Do you have a Samsung Device by chance?

Still not a good idea. If you want more power, then add a tuner or injectors fooling the ecm won't do anything other than trip codes.
