Electronic IP's, what's needed to drive one? - 300D50 - 12-06-2010
I've had this thought running round my head since saturday, so I had to eject it.
I know some of the newer diesels use an ECU controlled variant of the bosch pumps, but I'm in the dark as to what's actualy different internally. Is it just a servo mechanisim with feedback hooked to the rack, with little else, or are the other subsystems like the t-cap, full load stop, etc still there?
Is there any documentation of the signals needed to drive them?
Is there one that would fit on a 617?
Has anyone even tried to reverse engineer the ECU firmware, or modify it?
Sorry for leaving a brain dropping, but if I didn't I'd be thinking about it till next March...

The only thing inside is a solenoid that pushes directly on the fuel rack and position sensor for feedback.
There is no benefit to it in any way over the mechanical governor.

Direct rack control instead of a rube goldbergs concoction of springs and weights? Anti jerk control?

Hmmm, I'm intrigued... standard PWM at 5V?

It would be very loooong and pre-tensioned, and would not fit in.(12-06-2010, 04:43 AM)ForcedInduction There is no benefit to it in any way over the mechanical governor.

Anti-jerk would be the other main benefit.
Third would be the ease of tuning the engine (nearly) smokeless compared to playing 1000+ hours with ALDA.

Hm, so the question is, can I get one of these devilish things that will fit a 617?
Will one of the 60x 5 cyl ones fit?

There's a thread about this already. "electronic ip control" or close to that. Check it out & see how far it went.

(12-06-2010, 09:27 AM)winmutt Direct rack control instead of a rube goldbergs concoction of springs and weights?Whats complicated about a set of rods that has worked for 25+ years and never again requires adjustment once setup?
I spent all of 45 minutes adjusting my 300D's linkage when I installed the M-Pump and haven't touched it since.
Besides, in any case you'll still need mechanical linkage to control the transmission bowden cable and VCV. That means you'll have to rube goldberg a system to vary a vacuum signal to throttle position and the only thing you'd be really eliminating is the rod between the stop lever and the pump. (Obviously the manuals will be far more simple.)
Quote:Anti jerk control?My brain and right foot do that. My 240 used to do that all the time in 1st and 2nd gear when I first did the engine conversion. Once I learned under what conditions it occurs and how to compensate it hasn't happened since.
Its like this rear view camera "law" being proposed, spending $$$$ to solve a minor problem that can be solved just as easily (but far cheaper) with better drivers ed and stricter punishment for people that cause traffic related injuries.

I'd buy two.Quote:Will one of the 60x 5 cyl ones fit?Not without major machine work to the pump body so it will attach to the engine.

Seems to me the more electronics you add the more things that can go wrong. And the harder they are to fix when they do. But that's only my opinion.

Doh, there wasn't a US spec 60X 5 cylinder, was there? :/

yup NA, and Turbo its a om602.xxx

Maybe you could use parts from a electronic 605-pump on a 617 M-pump to build a electronic 617 M-pump.
I believe the electronic pump used on 605 and 606 are a M-pump...

The block is completely different and the electronic governor will not mate.
