If you get a vacuum proportioning valve, you could probably use the stock valve to cut off just enough fuel so that the engine stays exactly at max rpm.
(11-22-2012, 08:33 PM)OM616 I am going to eliminate the max speed governor on my personal pump, and I got to thinking that if I got rid of the vacuum shutoff actuator and made a solenoid one, I could build a module that monitored RPM and could set a Max RPM where it uses the shutdown solenoid to cut off fuel till the RPM drops to a certain speed where it turns off the solenoid and the rack is allowed to go back to full fueling. Basically turning the engine on and off repeatedly like a modern gas car.
Quote:This would allow full fueling right up to the rev limited speed, unlike the max speed governor, which starts cutting fuel long before red line.
Quote:Then to take it a step further, a stepper motor such as an IAC from an old throttle body injection unit could be used to replace the ALDA so that it’s function could be controlled by computer as well.

(11-24-2012, 09:50 AM)raysorenson How fast would the cutoff solenoid work? The more powerful engines in lighter vehicles will zip to redline very fast in lower gears.
What is a safe max speed for, say, a turbo OM617? If they can safely rev to 6500 rpms but volumetric efficeincy is worthless below, for example, 5800 rpms, would the governor perform adequately?
(11-24-2012, 09:50 AM)raysorenson How much of an RPM spread for max speed governor are you talking about? Can this be modified without side effect?

(11-24-2012, 09:50 AM)raysorenson This could be wonderful. Steppers do not need a position sensor to monitor movement so they can work in open loop, simplifying programming and circuit design. I haven't played with steppers yet, but I've researched installing them on my lathe for an NC conversion. A NEMA stepper in the 20kg/cm can be had for around $25.
MAP would be the only input needed, correct? The way the pump is designed, RPM need not be monitored for alda operation.
The issue of fitting the motor to the pump so that it can survive the vibrations would likely be the most complicated part.

I reckon the max speed governor does take too long to do it's job.

Me calling bullshit on someone on the intarweb is not personal. It's helpful:-)
You still sound like you don't know what you're talking about with this stepper motor stuff. Weather pack is what GM calls a sealed connector. I liken calling a sealed connector "weather pack" to someone calling nitrous oxide "NOS". Additionally, the uncrimped pins can be had from pretty much any sealed connector system and if not, wires can be soldered and heat shrinked. And finally, you'd need a very strange bird of a stepper for ALDA control if you want to avoid gear reduction, which is a deal breaker for me. I'd be surprised if you could find if you could find the ideal stepper under a hood.
On a more substantive note, why even use a stepper when you only want a small amount of linear motion? A solenoid would work faster, require no gearing and use only 2 wires with the price of needing position feedback. How much force is required of the ALDA?

Ahh, we're on the same page, you've just got the nomenclature mixed up. Unless you know something I don't, the picture you've posted is of a solenoid, not a stepper. Steppers rotate and require more than 2 wires.
While a stepper motor could get the job done, gearing would be required to change motion from rotational to linear. Since the linear motion required is very little, gear reduction might be necessary to allow a stepper motor to finely adjust ALDA position, unless you've got a stepper motor than can move in very small increments without detents, then you can just use a rack and pinion or worm gear to go from rotation to linear motion. The nice thing about stepper motors is that position does not need to be measured with a potentiometer so closed loop PID control isn't necessary. I don't like messing with PID control.
The best known automotive use of a variable position solenoid is an IAC valve and I see now why you mentioned IAC earlier. Steppers were used for IAC control in the 80's on some CFI setups but those gave way to solenoids. To my knowledge, all variable position solenoids in production automotive powertrain controls are used in closed loop and I don't see how ALDA control would be an exception. This sucks. You'll need a linear potentiometer ("string pot", as someone with your experience would know them;-) ) somehow rigged up to measure movement and, of course, fcvkin PID control.
It's starting to look like the M pump would be the best candidate for electronic ALDA control since a stepper could be more easily adapted.

A pic of where the step motor would go on the M pump. Possibly doable on the MW but the shutoff lever is on the other side and it might get too tight for a stepper.
If you just mapped against boost, programming would be super simple, adding throttle position would add another dimension to the map which I'd rather not play with right off the bat. Other options include valet mode (always a crowd pleaser), EGT and maybe even EBP fuel cut and passive anti-theft. I suppose you could also limit max fuel permanently if your pump is setup for 350hp but you've only got enough turbo for 275. Lotsa fun possibilities with this.

(11-26-2012, 01:00 PM)OM616 So to recap, we are not on the "same Page". The pictured item is not a solenoid, it is a liner stepper motor, the shaft does not rotate, but moves in and out in very small steps that are controlled my how many steps the motor turns. This unit has a very nice "Weather Pack" "4 pin" connector and is designed for use in under the hood conditions. This unit also has a threaded end so it can be easily attached to an adaptor to the pump.

I actually got around to opening up the boxes with the master injectors and stroke counter today. It is like Christmas, only I paid for the presents.
The variable frequency drive is the last major component left, and it is not cheep either, nothing seems to be lol.
Jeesh. Chill out fellas, we are all here to throw ideas around and talk to one another. I, for one, keep quiet if i think someone else posted something that was BS, because when i was little my mother taught me "If you have nothing nice to say, don't say anything at all"

cool thanks om616 , i was thinking that the cut out would be from the fly weights inertia pushing against the gov spring . i still dont totally under stand where there inertia plays its roll ,and on what . i was hopeing it could be as si mple as just uprated (underrated)springs everywhere for all the extra speed happenign .
as far as the max speed gov, as you said it would need to be at 7k to get fuel to 5k. is that inside the range of adjustabilty or would an diferent spring/max gov/ be needed.let say i want to set my pump up to run 5-6k no problems . assuming i could find a element with th right design . is it possibly to runn them at 50-6k mechanically. is that simply not accomplish-able with out removal and modulation electronically as your hypothesizing .
lever ratios? are these the "sring levers " show in some of the cut aways in this thread .
i figured id ask about the injector bodys, since some of these big power truck guys are running larger lines . diddnt know if it would help the balance with all the new higher flowing parts of the puzzle .i just pulled the pump off of my donor and im going to "examine " it now . ill start taking pics with a real camera soon .

thanks again om 616,
so i the process of building a "high speed" pump could some lightening of the wieghts vs finding heavier springs as well as a few select up rated springs create a realative harmony inside the pump or no ? lets say i had the fly wheel on the bench and a digi scale . i take 2 grams out of each fly weight , and balance them all to fleas tits . (i dont know the weight ) but i would assume 10% no more .
would that then only multiply the need forces in tthe other parts of the pump 15%-30-45 etc.
i get you when you say the fuel is gradually cut . i understand that what going on in there is a crazy balancing act 1 effecting 3. etc . i want to try to keep this build comp manual . no elec stuff cave man motor
as far as the lines , i figured id ask , i see that the volume increase in the lines would be a formula far from my math capability's. these ar on BIG power trucks sled pullers . i was just interested in seeing if this may lend a hand in the formula
seeing as everything on both ends is being turned up .
awesome tread BTW lots to learn , hope fully im contributing
The stock 617a pump is set to cut off fuel at 5200 (ish) RPM, and that is with the weights full out, so the weight assembly will tolerate the speed I think.
The reality of doing what you want, (regardless of how you go about doing it), is that to delay any reduction in fueling until 6000 RPM, I bet the rods would come out, or the valves would float before the governor reached the cut off point. Given that, why not just eliminate the high speed governor all together?
i was just curious , throwing out a little diffusion . as you said i could just eliminate the gov. 5200 is plenty high already i guess i was curious if the srings and or flywheel weights could play a roll in fine tuning . as far as returning to idle would the wieghts have a drastic effect ? or would messing around with the wieghts/sprigns potentially solve tunning an element with say on similar to a trucks i guess ?
(little off topic but as far as valve float ,has any one ever tried a second set of inner springs on an om head ?)
edit , i should prob have put the questions on your adjust thread . my bad =0

i was suprised at how much rev/range these motors had when i bought my benz . coming out of trucks as far as exp . i was amazed.
in another thread, cams are mentioned. could custom cam profile get that band stretched into the big numbers further ?
as far as making power up there : ive realazed that (at leaststock) holding the pedal on the floor in third at 45k to 55k does no more than letting the thing shift into 4th and do its own thing around 3-35k except smoke .
i had assumed there could be big problems screwing with those weights. id be interested in finding out what DM has done and its effects on the pump range.

I have an M pump on my 617 now (it was imported from europe at some point i bought it in arizona then shipped it to hawaii, also has a factory 4 speed) some one is giving me a turbo 617 this weekend, and Im not sure which one to build. ive been reading threads on this stuff for months, and am still confused what i actually need to do to build one of these pumps up. I probably read what to actually do, from dieselmeken and others but its confusing without seeing them apart infront of me.
I dont want a speed demon, maybe 180-200 hp, am I asking too much? or should i stop while im ahead and have a running engine? any advice would help

we dont have access to many parts here, and no junkyards unless you want to buy stuff from rusty hondas.
it has the manual 4 speed in it already. is that what you meant by slush box?
I havent found any decent shops here to do the work, I cant just buy slightly larger elements and put them in myself? it has to be shipped off? im sure shipping will cost as much as the work will.
for the brake conversion you need the spindle, calipers and rotors, anything else? and since we dont have any good junk yards here, can those be bough new at a napa or other auto parts store?

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

any updates for us? how is your venture going 616 i have a spare pump and i keep staring at the elements going maybe tomorrow... but if i buy them ill buy enough for all 4 pumps and try n find a deal on having all 4 done.
I know of one who has tried to balance the elements on the engine, but afterward the pump was put on a proper machine, and it showed how off they were.
this is so true om616, for all of those thinking it can be done DIY, think again, i've been there and got the t-shirt.
Here is a pic from Dieselmeken after i asked him to put the pump straight into the bench to see how close my DIY element swap was.
LEAVE IT TO THE EXPERTS.

Is it possible for you to tear the pump down and change the elements out?.... yes if you have the proper special tools to do it, and the service manual for the pump that shows how to do it... I know of a couple of people who have done it.... the issue is balancing the elements after reassembly, as this has to be done on a special machine. I know of one who has tried to balance the elements on the engine, but afterward the pump was put on a proper machine, and it showed how off they were.
If you have a Turbo 617 available and plan one putting that in place of the NA, then considering your location, you may be best served to adjust the Governor and put a VNT turbo on it, that combination will totally change how the car drives, and with the manual trans, I think you will be able to reach your "seat of your pants" performance goals. Just my 2 cents....

http://mercedesforum.com/forum/diesel-pe...all-46097/
talks about it a little, but have you done it? or know someone who has with any insight or procedure, benefits etc? i did a quick search on it and didnt come up with anything. would you still expect the claimed 20-30 hp increase by fiddling with the pump adjustments, and the governor?
also should I play around with the MW pump, in case i break it or anything goes south and save the M pump for a rainy day? or would the m pump see better benefits?
thanks for that picture it convinced me not to do it myself. out of curiosity are the tuned to be within 1-2% of each other? or what kind of tolerance is acceptable?

Sounds good thanks, I'll keep an eye out for that link unless someone already has it.
I looked for some egt gauges, I found some on summit racing tat seemed to have the best best price, do you have a preferred brand or a price range that I should pay ?
What about storing the injection pump, should I get the fuel out and replace it with diesel purge, or run it until it runs out of fuel before I take the engine out ?
What would be more beneficial in this case, the stock turbo, rebuilt, maybe with that 60 trim comp wheel that ive head about, or a hx35 or something like that ?
I think I might be getting off topic from the original thread,

so what is the best way to go about buying these elements? i have been to the web site and (i think) i have found the elements, but no buy it now or "cart". i see they have an ebay page, i even searched their part number in their shop, but no luck. I saw they have an american sales contact email. but alas i havent shot them an email yet. i am still looking for the barrels for the elements. are they just a part of the element? or do i need to order them as well? oh and if i do buy them, how will i know if they are the right ones? i have nothing to compare them to...lol how will i know a bad one from a usable one?

Well my 616 IP has finally crapped out...
On the plus side this should be the motivation I need to get a pump built with the new elements to see how they balance up, and if the helix needs to be ground to even them up.
I will not have my machine built in time so I will see about building the pump up and taking it to a shop to strictly balance the elements out for me.

Up date;
I did a compression check as well and the compression is really low, it is used up.... I found a good used engine to replace it with so I will set that one up with the new pump and an up graded turbo.
