Honestly I think these turbos would be too big for a 3.2L diesel, especially the HE551!... If anything I'd say go with a smaller turbo, perhaps an HX35 for the small, and then maybe use an upgraded HE351 for the low pressure

It sounds like this is something you're going to have to develop yourself to get it to work right...

I don't get the purpose of the brake sensor and the need to dump boost, nor do you really need temp sensors for oil and water on both turbos... the HE351 has a built in temp sensor for the coolant, and that's going to be really close to the oil temperature anyhow... You may want a temp sensor on the compressor outlet to control water flow in an air-to-water intercooler though.

Thanks for responding...

Question
How do you intend to redirect exhaust from the primary to the secondary ?

Answer
After the quick spool, the primary would  use the boost reading from the sensor placed at its intake to slowly open up the vines to allow excess to pass as boost builds, due to the secondary turbo. The secondary will open in response to the preset boost pressure on actuator. (reading will be taken from a sensor behind the primary turbo)


example/setting 1:

351ve maintains 3 psi at idle, quickly spools to 35 psi at the intake when accelerating (while lighting up the 551v), then then backs off based on pre-boost pressure (if pre-boost is 10 psi, 351 adjusts/works less to keep final reading to intake at 35 psi). The system should also do the reverse when the secondary is loosing boost, but no break has been applied.

However then the he551v reaches 15 psi the 351ve changes to simply doubling whatever it reads on the incoming sensors without creating a bottle neck, the rest with be controlled mechanically.

I hope that helps to clarify my intentions....

what sticks do you have?  5x16 apparently work really well with the VE pump... I was thinking of 6x13's but I can't find them in VCO. 

Put a 67mm hot and cold side on your huffer and you'll see why.. 400ish HP is just blah now... Going to do 191 DV's as well.. got a set for cheap

You keep going bigger and bigger on your sticks what's the deal lol. I'm considering going smaller with mine so I can open up my pump. It's at like the 300cc setting atm.

How do you intend to redirect exhaust from the primary to the secondary ? The VGT housings do not have wastegates and redirecting flow is going to require a great bit of coding since you'll want to resize based on speed, and compound pressure.

IMHO a twin 351ve would be simpler and probably more efficient. You can simply just double the cm^2 size, so 3cm on a single, is 6cm on twin's. Also simplifying control, you would just need 1 controller, and use just 1 shaft sensor and share CANBUS info.

The LBB isn't an EMS system, it is a system designed to control the Holset VGTs. So anything outside of what the turbo already has on it, I don't provide. If you need external sensors, for monitoring, which have no direct imput on how you want to control the turbo then I simply can't help there. The LBB is designed with 5v input in mind. So any sensor that has an output that you want to directly impact turbo resizing, that's well within the systems ability to integrate but I do not provide these sensors. There is only 1 extra ISR so you can count an external 5v square wave (engine rpm counting), there are 3 5v input / outputs (switches / relays control), and 3 5v ADCs (measuring 5v signals, tps / boost sensor).

Hi all, i am running a 4m41 engine (3.2 liter turbo diesel) and I want to run a crazy compound setup. I want to use the HE351ve as the primary/smaller turbo and the He551v (with mechanical actuator) for the larger turbo.

I would like to buy the controller but i needed a few things:

1. live RPM and boost sensor (will be placed between turbos) for the HE551v, along the the sensors for the HE351ve.
2. Temp sensors for oil and air for both turbos.
3. A control for water pump to increase flow relative to temp. (controls the water flow rate over turbos and over water to air intercooler)
4. Break sensor (to dump boost slowly or quickly depending on how hard the break is pressed)
5. Curves for a 3.2 liter engine

Can the developer hook me up and what price, don't see a number to contact him. I would even buy the updated unit from a member who knows to mod it.  Someone let me know, thanks....

haha, yeah,  I'm fighting with this new pump and bad injectors still.. I think I'm going to get a set of 5x016 nozzles for both the trucks.

I find this 215 pump feels a little soggy, might have to tighten the governor springs a click... I removed the fuel plate and that helped a lot... it may get reinstalled later.

I think you could set an alarm based on the VGT motor duty.. if it's greater than lets say 30% for more than a second or two there must be something sticking.

The above is all there really is to say. The LBB isn't setup to do PMW output, except some basic 0-5v, but without a load. If you wanted to design a sister board with some mosfets to drive stuff..  I guess.

If it's canbus, certainly, as long as you know the listening and transmitting addresses.

You could use my sweep command, and check the difference between commanded position and actual position. That way you know when something is out of whack.

I'll eventually start to code that in some kind of safety aspect to know when it's getting gummed up. Also it's not a bad idea to maybe code a semi clean up command, where you just full open / close 200 times in a minute.

I introduced some engine rpm based code today. LMAO truck is stupid stuuuupid fast now. So fast in 4th gear was chirpping over every bump and the damn air bag light came on! Tail pipe looked clean so I might have to open that fuel plate a bit :D
