Yes, the quad is %100 in control of fueling and timing the result is what I have posted in the videos. If you put the truck to oem tuning there is no way I could haul my horse trailer. I would have serious EGT issues and serious smoke issues hauling it up the mountain. The kicker is there really isn't much power difference in the truck offidle, with stock tuning and my quadzilla tune starting at %35 lower than oem fueling command. Key is that there is just too much fuel offidle with the 7 x .012's to not flood the turbo if you go WOT.

350 hp 700 ft / lb on the very high side

If you are sticking in the sub 425 hp area i dont see any issues with the s03, above that I would consider another route. I would still recommend bigger injectors and no tst over a smaller injector truck with tst smarty stack. It's hard to explain, but a 400 hp truck with smaller injectors and an aggressive tuning setup is not nearly as nice to drive as a big injector truck with mild tuning. If that makes sense.

To be fair the TST smarty stack does not stack canbus as the tst is a wiretap only box. The smarty by itself can command max fuel at less than %30 tps input but that is the catcher settings by themselves lol.

should be. I would revert the tune until I figure out a fix for the issue. I might have to upp the max fueling possible during high idle not sure. Can you verify that the egt updates when the app is frozen? Edit: Alirght this version is fixed you would have encountered the bug if you didn't have a custom tune loaded at all. This will prevent that issue. V2Idlesmooth.exe

Yea don't run that tune, something got messed up in the timing stuff. I am looking now Looks lik eif you don't load a custom tune the tune gets messed up. Fixing now

Yep, its a great turbo.

Alright anyone running the v2 stuff that wants to mess with the new stuff you can run this flash. The idle to fueling handoff is signficantly smoother. This has the gallon trip and eco gauge and boost offset built in, but the json file isn't in place for the app yet. This SHOULD read 0 psi at idle, but I can't be sure so let me know. Once the update on the app side comes through you can start using the mpg stuff. I would be interested in feedback in regards to the offidle stuff.

I will have to look it's been a long time since I built it lol. I believe there is a cap or something in place on the vr - /+ lines

At this point I am a much bigger fan of bigger injectors and less aggressive tuning. If we can see what the revo settings are doing and you can manage with the smarty only and some bigger injectors. I don't feel like the smarty / tst really fight each other so in terms of the stack it is fine, but will it support your goals, I am not sure. I would jump up 1 size of injector rather than do the tst. Bigger injectors are just more meaty in the power band.

Here's how you wire up the 9924 chip 1 vr+ ( turbo +)2 vr- ( turbo -)3 NC ( not connected)4 GND 5 GND10 +5v9 GND8 NC7 IO8 + 10k + 5v pullup 6 GNDTop left is 1, Top right is 10Bottom left is 5, Bottom right is 6 pin 1/2 go tot he shaft speed sensor. then 5v and grnd when specified, then pin 7 goes into the pin on the arduino with a 10k resistor connected to 5v I can try to take a picture later.

Simply stating that I would not classify the Smarty s03 as set it and forget it from what I am seeing in your guys testing. there is a lot of testing that goes into it as well. thats it, not to say the smarty isnt up to the job. The stack question needs more input in terms of goals.

What size injectors are you going to end up with? that's going to determine the answer you get. without being a butt I would like to point out the size of the thread for the revo settings... it is nearly as big as the Quadzilla thread lol. Doesn't seem like guys running the s03 are really saving any time in the test and tune area.

have you followed the troubleshooting in each of those articles? the first one seems typical for lockup though.

What sensors / inputs are you wanting to use? Are you using an arduino uno or mega? Are you doing shaft speed code or boost to drive control?

No I don't. I write a diagram for it if you like.

sensors pull power / ground from the arduino, the turbo is on it's own relay.

I wish I was at sea level to do a video. I bet people would be surprised how clean these injectors are at sea level. The altitude makes 50's seem like 100's in terms of smoke output.

@pepsi71ocean Heres an example of these 7 x .012's on stock tuning Snap input and lug down tests.

HE351VE here, built in EB. It is very hard to find a better turbo for sub 450 hp when towing. You can find them all day long for $500, few hundred bucks for a controller from lilbb.com or make your own with my code and off to the races you go.

You are comparing different injector sizes. the 7 x .009's have a starting point of %15 below OEM fueling commands, the 7 x .012's start at %35 less than OEM duration. Timing curves are the exact same in the videos @pepsi71ocean I have never noticed a big difference in smoke as a result of small timing changes. The smoke contorl you are seeing is %100 the fine tuning of the canbus fueling command and the better atomization due to pop pressure. I am cutting OEM fueling by ~%35 offidle. You can see the fueling graph below. All Snap throttle input to %100 TPS from idle. Orange is my Quadzilla tune, Blue is OEM and gray is SW3 on a smarty. If I was to run on oem tuning it would be a smoke show, same as sw3. No amount of Revo settings would help.

I can't confirm it actually retards timing, my guess is it does, but I have no way to tell for sure. It isn't much if it is there. like I said after ~1300 rpm you can't tell the difference. The fuel atomizes better, but I dont think timing is a huge issue.

Yes,

Check for AC noise

Yep very similar to a boost fooler. The HE351ve is a GREAT turbo so long as you don't push it too hard. That's the issue with 6.7 guys, they expect it to take too much. You could write in a DP control routine, but I have found that if you keep the turbo under 450 hp the turbo is happy and DP is nearly 1:1 up top. That's the beauty of the shaft speed controlled system, when you start seeing shaft speeds of 120,000 rpm the vanes open to keep shaft speeds in check AND keep the turbo in it's map.
