I may have mis-spoken. I have an injection pump from a 3.5l OM603 right here and it has boost enrichment/ALDA. The '95 OM606 pump is virtually identical and if it does not already have the same setup, I believe one could be fitted.

The 606 engine can have a 603 pump fitted, but you can't add an ALDA to a 606 pump without serious internal surgery. The normal swap is to just put the whole 603 turbo pump onto the 606 engine (usually, a 606 turbo engine).

The 606 pump has an ADA, which will correct for altitude, but not boost. All normally aspirated diesels have this except for the electronic pumps from 96-up.

Actually it can, they work in exactly the same way. The ADA can also be replaced with an ALDA.

Pretty sure it's not capable of providing the same amount of fuel enrichment though. You know anyone who has taken a NA pump, slapped on an ALDA, installed in a turbo engine, and actually verified it puts out the full turbo rated power? Particularly with a 1995 OM606 NA pump?

No reason why it wouldn't work, the governor is the same.

Hmm, lets see, an ada is designed to compensate for changes in air pressure due to altitude. In driving from sea level to say 10,000 ft you see a change of about 4 1/2 psi. The ALDA is designed to compensate for a pressure change of 12 to 14 psi due to turbo boost. Not exactly the same. Similar in function and maybe worth investigating, but making a declarative definitive statement is misleading. Maybe once you open up an IP and make a few adjustments and obtain some trial and error data of your own you can make a constructive contribution to threads having to do with pump adjustments. Until then why don't you quit misleading others by posting on a subject where you have no direct experience.

I'm gonna have to agree with Forced here, the ADA and the ALDA are more or less the same device and will function identically with boost applied. The ALDA "opens up" so to speak with only about 1.5-2psi boost applied, so theres no reason why the ADA wouldn't serve exactly the same function as an ALDA if you ran a pressure line from the manifold to the inlet, rather than leaving it open to the atmosphere..

If it were that simple, Bosch would not have needed to create both an ADA and ALDA, now would they? Turbo and non-turbo engines would have all used the same compensation device. But they don't.

I'm all about experimentation, and collecting valid data to share with others of similar interests. Making mistaken, careless, or misleading statements on a public forum is what I have a problem with. If you use words like exactly or identical you'd better back it up. In the case of forced, correct me if I'm wrong, but he has not ever made an IP adjustment nor collected any valid data regarding IP functionality. I have seen him stomp on others helpful posts or creative inquiries. I do respect and appreciate his work and info regarding VGT. I should just take a deep breath and let it go, at the end of the day misleading some Noobs or dissing Dave (who has always shared his pioneering, excellent quality work) is no skin off my back.

Actually the ALDA is designed to compensate from 10psi to 27psi absolute pressure.

Saying that the ADA can be replaced with an ALDA is not at all misleading, its fact. Its not a simple "swap it and you'll get 120hp" deal, the pump is the same but it requires adjustments to take advantage of boost.

How about to do some actual research, for once, and stop making assumptions on things you have no clue what you're talking about?

Something you have not done and I have.

Then stop.

I have.

You haven't been around here long have you? Humm, you must have missed my experiences rebuilding injection pumps back in school and teardown of a 616 and 617a IPs.

I treat others as I'm treated. He began by insulting and attacking me out of the blue so I lost most of my respect for him, you have done the same here today.

Once again your powers of observation and memory are suspect at best, take a look at the upper right corner of one of your posts then mine. Who hasn't been around here long?

I was doing pump mods in 1999 and posted the first pictures of an MW pump with the back off on the internet and identified the function of the various adjustments. I've shared my findings and tried to encourage others.

You seem to have a poor grasp on the meaning of words or the implications of what you are saying. You've done some interesting work but you come across like a pompous ass when addressing the inquiries of others. If you don't mean exact don't use the word if you do back it up. Internally the NA and turbo pumps are differently. That is a fact.

If you have made internal adjustments on your IP what were they and what were your results. I have asked you before and you've stated that you've made no adjustments.

It is really not worth my time to argue with you, but when you repeatedly make emphatic declarative statements that serve to mislead or discourage others it rubs me the wrong way. I'm sure you are a decent guy, and you would like to come across as an expert on this topic, the thing is none of us are. Give it a rest, I'm going to. Maybe I've even earned a ban. Hey a guy can hope.

Once again your understanding of sarcasm and irony are totally absent Mr. 263 posts.

Um, clearly the opposite is the case here.

Boo hoo. If you don't like my methods, don't read my posts. Simple as that. Have to seen the "ignore" feature here?

Not true.

Search, for once, and you'll find.

Then please, don't. You'll save yourself from embarrassment.

Put up or shut up big mouth, what internal adjustments have you made to your IP and what were your results.


There it is, throw it in my face if you've done it and i'll never post here again. how about the same for you when you can't.

Please, member since 2000 and 264 post master, what have YOU done? This isn't a one-way street, especially with someone with so little credibility as yourself.

From searching through your collection of 264 posts, the most I can see you've done is little more than played with poorly mounted intercoolers, fiddled with the full load stop adjustment and installed a post-turbo pyrometer on your SDL way back in 2005.

http://www.***************/forum/showthread.php?t=264


See, I've done the work to LOOK for what you've done since you seem unable to provide it yourself. Can't you do the same?

Okay, I get it, you're unwilling to look. I'll make a quick breakdown for you.

Disassemble, rebuild, test and tune Stanadyne and Bosch injection pumps and unit injectors in school.
Swapping in a non-stock engine to my 240D.
Removal of the rack limiter and ALDA.
Installation of a turbo with technology 20+ years newer than my engine, fabrication for its fitment and control.
Testing multiple intercooler systems.
Testing multiple air intake designs.
Testing different types of injector nozzles and 2-stage injectors.
Exhaust modifications, including making my own 3" exhaust from scratch.
Aluminum welding to modify my turbo and intake manifolds to fit my needs.
Buying a second car that will be focused on improving performance.

Shall I go on or are you finished embarrassing yourself?

I have searched and I find NO evidence of this claim. In fact as recently as 2005 you were asking very basic questions about how to adjust the pump!

This leads me to believe you may not be telling the truth and/or you're embellishing.
