Help with surging stand alone He300vg
« on: October 24, 2017, 08:57:11 PM »
So just finished my 2001 cummins swap into my 2002 f350 and need some help with the turbo. My truck is running
New SO VP44 pump
7x.095 Sac injectors
Quadzilla v2
4" exhaust
ZF6 manual trans with dual disc valair.

So far I'm loving the truck but feel I need to do some tuning on the turbo or maybe I have something wrong. At light throttle steady speed the turbo will drop to 0-5psi then surge up to 20-25psi then back down, back and forth. It's very annoying. If I step into the throttle harder it builds boost really fast, pegging my 40psi guage and pulls hard. It just seems like it's either building max boost or building nothing.

I wired up the "cruise" setting and it is a lot more linear, builds boost related to throttle input and load up to about 10psi. I don't experience the surging like I do in the normal mode. Not sure if that is helpful or not.

We are getting ready to pull our 32" gooseneck loaded down, to Colorado and would really like to have the turbo working at its best. Does anyone have suggestions that could help me?

Have you connected the Bluetooth app yet ? Probably just need to loosen the curve

I have not been able to get access to an android device yet. Planning on meeting up with someone this weekend. Just wanted to get my ducks in a row for when I do use the app since I will only have use of it for a few hours. Unfortunately I have to drive to Colorado to use the phone. Everyone I know around me used iPhones.

Is the app pretty self explanatory as to what to do? Suggestions?

I was going to open the box this afternoon and try to move the jumpers on the rpm curve setting and see if that helps at all.

Once again any guidance would be much appreciated.

I set your box to my custom curve as per our conversation, so you won't be able to alter the curve since it is set to use eeprom values on startup.

You'll need to get in on it through the app and either update the values in eeprom or set it to not use those values, and then it'll default back to the jumpers, which you can man handle.

Default pin is 9220, you can view the app on google play : https://play.google.com/store/apps/details?id=com.devnull.lbb&ah=tjuL05xs8ST5MKrVQjh6KcEcAj4

They will need to opt-in on the beta testing here : https://play.google.com/apps/testing/com.devnull.lbb

Any guidance as to what values to change and what to change them too?

Truck runs great everywhere but light throttle cruising. Doesn't matter the speed. 10mph through the neighborhood it surges boost up and down and freeway same thing

Smaller numbers bigger turbine ie slower spool.

I would find out what rpm it starts surging up to, and just lower that value. If it's at 55k and it hits 80k then comes back down, you know that range needs to be lower.

So finally got some time and bought an android tablet. I got the app downloaded and connected to the box.

I can't seem to adjust anything in the tuning section. Everything is light gray except the refresh button flashes dark gray then back to light gray. Touching any of the areas doesn't do anything.

On the main section it shows the current position and rpm. All that seems to be working.

Any help??

Ok, I got it to connect. I will play with the settings and see what I can do.

Last 2 questions
What is the walk down setting?

And is there any point to adjusting the rpm higher than 80k? On the drive home I saw around 110,000 rpm

The tuning section correlates to the turbo curve pre-top end code. So basically the 80k entry is the final step before the turbo is about to just take off.

If the turbo is taking off too fast, just continue to lower all the turbo values by 40, until it seems just about right. You want to cruise around 60k but when you push the go pedal you want it to take off. Finding the balance is the tuning part :)

Baron,

My current tune is as follows

17000: 840
20000: 800
26000: 780
37000: 750
65000: 710

walk down rpm : 22000
idle rpm : 12000
*** however I am watching TPS so my walk down RPM is null and void unless off the throttle.

@hakcenter

How should Baron be opening up the vanes alittle more in the 100,000 rpm area?  His truck seems to be slingshotting from the 80,000 + area causing the vanes to jump open and loose boost. 

Is he running the canned 2.0 code you have posted?  He is local to me so I wanted to increase the vane size a touch up top to try and slow the turbo accel down when at the top of the map. 


Code: [Select]
        // TOP End Control Section
               if (performance_mode && turbo_rpm <= 120000) { vane_position = map(turbo_rpm, top_end_rpm, 120000, turbo_curve[4] + performance_position, 520); }
        else if (turbo_rpm <= 120000) { vane_position = map(turbo_rpm, top_end_rpm, 120000, turbo_curve[4], [i][b]500[/b][/i]); }
        else if (turbo_rpm <= 128000) { vane_position = map(turbo_rpm, 120000, 128000, [i][b]500[/b][/i], 280); }
        else { vane_position = map(turbo_rpm, 128000, 130000, 280, min_position); }
        if (turbo_rpm > [i][b]122000[/b][/i]) {
          if (turbo_accel > 60) { vane_position -= [i][b]one_cm;[/b][/i] }
          if (turbo_accel > 90) { vane_position -= [i][b]half_cm[/b][/i]; }
        }
        // Overrun protection
        if (turbo_rpm > 130000) { vane_position = 0; };
      }

Thinking about moving that 500 position to 400 then adjusting the accel adjustment over 122000 to start at 100,000 and altering the change to a half and half vs one cm and half


can I just adjust the stock 2.0 code and upload or is his box running something else?

I'm pretty sure he's running my personal code, with some subtractions.

If he is surging in the upper band, I would just make 280, 380 and leave it as is. The accel over shoot is there to get the turbo stabilized.

We can make a new thread in the 2.0 area. Baron should have the code on his laptop if I'm not mistaken, I've remoted him.

I will chat with him about that and we will take a look. 

We are troubleshooting other things, but his truck is nearly identical to my old setup and it was running great without any of the issues he is having now. 

Is the andriod datalogging feature working?
