I am looking for all possible working controller options for a GT2359v. I would love to have it work with an arduino which I already have but most of the projects I come across seem be quite open ended still.
I am aware of the very popular DIY found here http://dmn.kuulalaakeri.org/vnt-lda/ , but I am not sure how well the code translates over to an om617 in my case. I am also wondering how people are hooking up a throttle position sensor when using arduino.
I am also interested in more specific info on getting a vacuum type controller to work as well. Any info will be appreciated.

The cruise actuator has a tps of sorts in it. Could be usable as inspiration for fabbing one.

Has anyone ever tried to pull a signal off of the cruise control box that can be read by an arduino? I know it can be done on other vehicles, but have not seen any writeups anywhere on old mercedes diesels. I have ordered my arduino and some accessories but I will be a beginner. I would like to think that it would then be possible to have an arduino based cruise control as well.

It's just a potentiometer. Lots of writeups on reading generic potentiometers with arduino. Someone already made a modernized cruise controller for diesels awhile ago, it's too bad he's not selling them.

1985 injection pumps had some kind of a sensor on them, I believe it was a TPS.

I ran a vacuum system on mine, with a manual override switch. It wasn't the most efficient but it worked.

I had one vacuum actuator on the turbo, the stock one from the Jeep I believe. I ran a 2056V.
With the switch set to race mode, the vanes were pulled closed until I hit 18psi and then they relaxed enough to keep me constantly at 18psi.

In cruise mode, the vanes were completely relaxed and the turbo built around 8psi-I used this mode on the highway.

I was going to add another mode for 12psi but I ended up scrapping the car first.

The downside to this was that air could be (and probably was) pumped back into the vacuum system. When I redesign all this it will be a bit more refined, although still a mechanical manual operation.

RPS, rack position sensor. Depending on how you define "throttle" on a diesel it's the same thing or it's closely related.

How about on the M-pumps? Any RPS sensors on those?

The 60x m-pumps have an RPS.

Note RPS is not exactly a TPS, since the rack's position is skewed by the ALDA and the governor(s).

The RPS is a bit of a paint to read from as its a coil construction so you need an amplifier and you also need to reference between the fixed and moving coil. It isnt any use to you here anyway since as aaa said it isn't directly linked to peddle travel. Far better to use a pot like a normal TPS, something like what is fited to the electronic pump 605 606 might be of use where you could loop through in some fashion.

The project you linked to should work with any turbo/engine you just need to map it to suit. You will also need to ditch the servo and use a vac module instead.

I think I am going to use this Cable operated TPS I found and just hook it up like the cruise control servo. https://www.hgmelectronics.com/display/h...ion+Sensor
For a cheaper alternative Google "string pot" for string potentiometer.

maybe there might be a solution here for regulating the vnt by vacuum .they also had a free switch offer http://www.hinghambay.com/ i found this company while looking for a way to replace the 2/3 way switches for the egr tranny vac . i still dont have the best grasp of vacuum tuning with the zone resistors . so i thought something like this would be a cool solution for replacing the switches with a progressive overlap when i get the hang of it .

Why not control it mechanically, with something like this?

-1982 300D Turbo, 280k miles, ALDA apparently maxxed, fram 8038, 12 lbs boost, non-egr manifolds, W/M injection, 4 brake light mod, Gen II w126 front rotors/calipers, 4-speed swap
In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)
-1980 300SD, 110k, project car. Goal is to get it lookin' like it did on the showroom floor (body and interior wise, not necessarily under the hood )
-1974 240D, FRESH PAINT!!!!!!

I will if I am unsuccessful with Arduino.

I have made a Boost controller width arduino, actually it was only made to control the 722.6 Gearbox, but the controller also have a Boost controller build in.
It can control a VNT turbo. it need to know TPS, Boost, EGP.
Then you can programme what Backpressure / Boost you want at any TPS
Here is some picture from the menu
https://docs.google.com/document/d/14O89...tLViA/edit
The controller gives a PWM signal to a Vaccuumvalve witch control the vanes width Vacuum

1996 MB SL320 Now OM606 7 mm pump elements (myna), KKD manifold, HE341VE, 3,5" downpipe, 3" exhaust, big IC, 722.6 gearbox controller, also controls (Turbo VNT, EGT, BOOST, EGP.)

In real life it is smooth width a big VNT turbo testet on HE341VE and HE351VE,
On a normal turbo it can have a little spikes, testet on the standart OM606 turbo.
But you also have the possibility, in the controller to set PWM vs Boost/RPM/TPS, then you have total control how it should control.
Yes it interpolate between the values. = "smoother control"

You set PWM = 100 at 100% TPS
You set PWM = 50 at 90% TPS

If the TPS is 95 then the PWM = 75
