Boost Control of the Holset VNT HE351VE - olefejer - 08-29-2014
Hi
Long time since last update of my Gearbox Controller.
New PCB is made that include CAN BUS.
New housing is made.
But this is to show that it can now also control the Holset HE351VE Turbo.

And it still controls the Gearbox 722.6 :-)

Are you still doing PWM, or did you go back to CAN?

Yes it still does PWM for Vacuum valve to control any vacuum actuated vastegate or Vanes on the VNT turbos.
The CAN bus control of the Holset is just extra bonus.
RE: Boost Control of the Holset VNT HE351VE - Turbo - 08-30-2014
can it control a 7g tronic gear box or is it coming up?

Will it do the HE341VE too?

No it can not control the 722.9 i know it is fully Can Bus controlled.
But i think it is a bit difficult to get hold of the codes.
Bu if anyone has them i am interested ;-)
(08-30-2014, 03:03 PM)raysorenson Will it do the HE341VE too?Well if it has the same controller it should work, but i am not 100% sure, i only has the Controller from the HE351VE.
What color does you wire has ?
The HE351VE has
RED Gray stripe (+12V)
Green White stripe (GND)
Yellow (CAN H)
Green (CAN L)

This is an interesting device. Tell me about it! If I run a om606 lets say and have a mechanical superpump on that. I have a manual transmission and the engine is in a w201 chassis. Can I still use your controller and how does it work?
What I'm thinking here:
If I'm to use the can-bus controller on the he351ve I want the turbo to act and react on my demands. Like open vanes on highway cruise (part throttle) but be struggling for boost as soon as I flick the throttle. I want it to give me different boost depending on RPM. Maybe calculate gear on speed and RPM and then give me different boost depending on gear. Maybe give me fully closed vanes when stationary to create a diesel-launch control. Maybe have closed vanes on engine brake (like the trucks have) to be able to power lock the wheels while drifting... Yea, and much more.
I'm not familiar with this device you have made so please work with me here.

This thread http://www.superturbodiesel.com/std/Thread-Gearbox-Controller-722-6-ver-2
He uses turbine inlet pressure vs boost when engine load (measured by throttle position) is too low to require maximum boost. As i recall from the first thread for the version 1, it will also control an electronic speedo from a V8 124 if you like stock looking instruments.
It's an impressively full featured device for the Mercedes and his pricing is competitive with VGT controllers that do nothing other than run a turbo. He should be selling these by the truckload.
RE: Boost Control of the Holset VNT HE351VE - hooblah - 09-01-2014
This sounds perfect for my needs!
I was planning on buying an electronic speedo controller to go between my 6 speed and 124 v8 clock. And I was even considering doing an arduino project for a vnt.
But now this shows up...
Price?

(09-01-2014, 11:54 AM)raysorenson This thread http://www.superturbodiesel.com/std/Thread-Gearbox-Controller-722-6-ver-2You are Correct.
He uses turbine inlet pressure vs boost when engine load (measured by throttle position) is too low to require maximum boost. As i recall from the first thread for the version 1
It has 10 point wanted boost depending on TPS. )
It has 10 point wanted max (EGP - Boost) depending on TPS
It has 14 point Limit boost depending on RPM
It has 14 point Limit boost depending on Speed.

Awesome guys. Great stuff this! Thanks for the reply.

Care to share what CAN addresses the VNT motor responds to?

(09-07-2014, 10:09 AM)baldur Care to share what CAN addresses the VNT motor responds to?Yes
The outputValue 0-255 is 0 - 100% vanes position
How are you going to control it, depending on Boost and EGP ?
unsigned long ID = 0x0CFFC600; // Extended Message ID
byte length = 8; // Data length
byte data[] = { outputValue, 0x02, 0x01, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}; // data message with an added counter
CAN1.send (ID, extID, length, data); // Load message and send

Thanks! The plan is to control boost with a target mapped by throttle position and engine speed.

I think I read you said somewhere that you tried to have the vanes as closed as possible with no more than a .3 bar difference between the EGP and Boost Pressure.
Why not just have a diapragm actuator to do exactly that, maintain a .3 bar difference between the two?

You mean a diaphragm that controls boost by maintaining a constant pressure delta between exhaust and intake with no other type of boost control? Because spool up on throttle tip-in would take too long or maybe never happen.
