Only thing I've seen is the one Randy (carcrafter22) did on his 3.9 Isuzu.

He listed part numbers and sources, so it should be fairly easy to replicate for anyone with one of the turbos you mention.

Search his username and VGT or something similar, or just threads he's started.

Hope that helps.

 

Use the search function....... There was a long thread about standalone controllers and such....... and many other threads.... also search on competition diesel.

 

there is a few guys on youtube that are using internal waste gate actuators to control the vgt it looks like they all do pretty well too i plan on trying one just to see how they go

 

was the aussie-spec powerstroke f250 fitted with vgt? you must remember that a 4.2L straight-6 mwm diesel was also offered back there in the oz and some rare versions of this engine were factory-fitted with an all-mechanical vgt setup...

 

a good number of people on cummins forum have done this with great result. the only standalone i'm familiar with is the Fleece and it is only compatible with the electronics on 98.5 and newer dodge trucks.

if you are going to tow with this, it's a great turbo as it closes to a very small housing and allows exhaust braking (may need 60lbs valve springs)

 

here is a free programmable standalone VGT turbo controller. the code is open source, and the microcontroller is ~$35. the program can also do fuel control too.

Keaton, what is the consensus you've seen on the skill level required to build and program that?

 

the arduino is already build, the drivers are easy to install. programming requires downloading the source code & SDK and hitting the upload (via USB) button on the SDK....
then uploading maps can be done over the serial terminal

now mapping on the other hand... different story..... you gotta know what you want it to do. he has examples on there on what to do..
you can set it for target boost (based on RPM & TPS)

so if you know what you want the turbo to do then it should be easy

Fleece Performance has announced that their stand alone 12 valve VGT unit will be out by the end of this month. Price is $625 including MAP sensor. This unit will also include the exhaust braking function. It also has a USB port for custom programing. I think it took them almost 2 yrs to build it. The problem seems to be the computer language used by Holset in the ve turbos. Took a while to break it all down. This may open up a whole new market for all those HE351ve turbos you see on eBay. Might make these a viable option for the 4bt.

 

How does a vgt turbo compare to a set of compound turbos peformance wise?

 

I think Fleece is also trying to develop different wheels for these turbos. I think that it would be a whole new world of performance for the 4bt.

 

I wish I were a computer geek and understood all the things these guys are doing. Why don't they just build the unit and sell it? You also notice that in all the tests and video they are using gas engines even though they are addressing mechanical diesels. To use this module I guess we have to figure out where to put a TPS. RPM and MAP wouldn't be a problem.

 

I wish you were not a moron.... the video is a diesel, turn the volume up.... then look at the pictures.....
TSP would go on this thing called the injection pump, maybe you have heard of it......
RPM is coming on the IP gear (belt driven)

also if you wanted a plug and play box then your gonna spend $600+ not $50 +/-. i say $750 is worth doing some reading/HW to get this

yep.. sounds like a gas motor to me..... or maybe its a diesel

Guess I am a moron. I'll run right out and find the TPS on a manual transmission VE or P pump Cummins. Don't think I'll find one though. I know they are on automatic transmission models to control upshift and down shift but haven't seen one on the manuals. When the engine is mechanical and has no computer control what would you need a TPS for?

 

this is basically a computer retro fit....you will have to add a TPS. Notice the picture above.... He added one to the top of his manual, mechanical VE pump....

You need a TPS to tell the microcontroller what you are doing.... That way you can do target boost. Ie your at X RPM & pushing the pedal Y hard so the boost should be this Z. Its a 3D map......

 

Keaton, thanks for the info and pics, might come in real handy on my next project.

 

im working on this setup on my 4bt, have a few pics up of my build

i'm not to sure i haven't really been to interested in the f250's mainly way out of my price range so i never really looked into it But now you have brought it to my attention i will check it out.

 

i'm not sure if the 4.2 was sent back there with the vgt, but the 7.3 was...
