anyone used this for a 617-95X?

(04-05-2018, 07:33 AM)baldur Wow that's a lot of money!
I don't know what your controllers go for Baldur but this one is about $750:

It works for holsets and many other VNT turbos also.
FYI. I have never used any of them, but would consider doing so on next build if compounds are not doing well enough.

Mine go for 650. That does not include any wiring but it does include software that is far more refined than either of the two examples in this thread, and it controls everything related to the engine and not just the turbocharger.

If you have a 617-95X then there is nothing other than the turbo to control. Do you have a system which is plug and play with that in mind?

Not plug and play, no. I mean I have more than one product that can do it but none of them have boost control as a primary function, they're designed to do other things but can also do boost control.

Even the relatively simple ECU on the OM606 does this with the computer controlled wastegate. It runs the pressure up high enough to meet the fueling and no more. The wastegate is constantly moving back and forth in order to manage boost and provide back pressure for EGR performance.
Boost control for any kind of modern diesel really should be based on a computed air demand. Running the intake pressure up to some arbitrary value just adds to exhaust back pressure at times when the engine isn't at full output. And that is basically 99% of the time.

Edit- no idea why my sig says "Holset". Anyone know how to change that? thx

lol- Is the 617-95X a "modern diesel" ? Mine doesn't have a EGR, nor does it have a computer. Do I want it to run high boost all the time? No. Do I want boost at low rpm? Absolutely.

(04-06-2018, 10:09 PM)AlanMcR Doesn't really matter if it is modern or not. The vanes will get closed down all the way even if there is no need for boost.
Yeah, but that just means to control the VNT properly a throttle position sensor must be fitted as well as engine speed sensor so the pressure target can be varied depending on throttle position and engine speed.

...and we get back to the first post: can you make this for a 617-95X?

85 300D om617: 8mm M pump 175cc 5200rpm, holset he221w @ 30psi, large A2W ic, compounds on the way.
what are your power goals? you said you want something quick spooling for down low torque and drivability but how much power do you want? if all your aiming for is 3-400 thats doable with a nice single that will light quite quickly. for example for the price of that vnt controller and a good HE351 you could get a borg warner EFR 7163 which would have much the same response while also being a more responsive turbo with more features as well.

Now: Q7 V8TDI 240kW, 320d 150kW, 335d 210kW
There is a guy.. dmn? He made it free on arduino base. Uses pre-control and PID regulation, inputs are engine speed, pressure and throttle demand so pretty much OE like. But not everyone is handy enough with electronics to use it.

It is open source.
Shouldn't be too complicated to make a controller with some basic electrical knowledge, and for far less money, I'd say 50-100 dollars max for the entire project.

The EFR 7163 doesn't come with a T3 but that can be overcome.
I'd like to have more than the low 200's- but not more than 300. I don't want to be buying and installing new transmissions on a regular basis... plus I don't have a LSD.

a Holset HX30 will support around 250 at the max. the HE221W im running now will do about the same and it lights well below the torque converter stall. if you are aiming for less than 300 then theres no point really in going vnt. the controllers you were looking at are mostly for larger modern VNT turbos like a HE351 but that is good for more like 350-400HP. below 300 there are plenty of readily available options for much cheaper than a controller and turbo that will light low enough to make for a fun drive.

likely a bit more than you need the 6258 should supply at max about 320-330 worth of air. also you would need to plumb coolant to it for water cooling. since your power goals are small i would just go for a nice genuine holset HX30/HE221W or a garett GT2859 or similar.
