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

If it takes commands over CAN bus it should, though the code might have to be modified

I have a garret GT4082klnv, would this controller work?

Well, bunch of stuff to cover today

I got my pump in.. lots of tuning to be done before I make a final verdict on how well spent that money was.

Couple notes though.. When I pulled the drain plug out of my old pump, the fuel left in it smelled of diesel, but the crankcase didn't.. so it had a small leak I guess..
I also bought a pop tester for nozzles.. not a great quality unit but it'll do the job for $90... So I tested all the nozzles I have that aren't installed in a vehicle.. Looks like the last set (5x014s) I pulled out because one failed.. well, it was the #2 cylinder that died AGAIN... 3 of the 5 holes were plugged solid.
I'm going to go out on a limb and say the #2 barrel in the injector pump is chewing itself up and spitting garbage down the line and the injector is dying because of it.
Then I tested the Marine 370's I had, they dribble like MAD, they don't pop cleanly at all!

Other problems I had was my turbo was acting up, I thought it was the actuator dying... When I'd start it cold it would run WAAAY too closed, it would feel like it was in engine brake mode when it was commanded to position 800 or less.
Took that apart, found out that the sliders for the vanes were carboned up and were nearly impossible to move when close to the wide open position, so the actuator would mistakenly think it was wide open when it wasn't, thus being more closed than it thought it was.
I had a new CHRA so I just tossed that in with a known good used actuator, I'll fiddle with it later.  I also bought a brand new actuator from someone that didn't need it for $250..

I'm debating what size injectors nozzles I should get now.. I have 5x012 155* SAC's, 5x014 145* VCO.. Kinda thinking of getting some 5x016 VCO's.. Maybe try some 6x013's too but they only come in SAC.. at least I haven't found a place that has them in VCO

Other than that, it's calving season here again!.. got two bouncing little babies

good to hear you got it working :)  can make a fair bit of power with the 67mm wheels :)
