(03-23-2009, 07:40 AM)Tymbrymi No offense, but HAHAHAHAHHAHAHAHA. ROTFLMA.You could probably get something that would move the rack in an afternoon, but there is no way I'd put that on my engine! Also, keep in mind that all of these actuators will require additional power electronics to control them. Most microcontrollers can only output 20mA per pin, and actuators can require *significantly* more than that. Especially when you change positions very quickly!
.....
Forced... stop reading now.
For the OM61x pumps you could replace the elements yourself. The synchronization is mainly performed with the pump's camshaft, and the most important part of adjusting new elements is balancing the amount of fuel delivered. The MW pumps have external adjustments for that, and with large enough graduated cylinders you can tune those yourselves. Yes, I know Forced, it won't be 100% perfect, but I think we can get to 90-95%. We will always disagree on this...
Yeah, so I was a little arrogant/foolish about the software... but its no space shuttle either. Basically it all comes from tach sensor input, EGT input, boost input, rack position input, fuel pedal input, and spits out electrons to the actuator controls. The "actuator controls" consists of a relay or set of relays that can handle the current the actuator needs (or if you have electronic turbo controls, actuators plural).
The software is a great big loop that sniffs for all these inputs and does things based on what it smells. Granted, its no afternoon project, but I still think it won't be terrible.
It would be nice to also have ambient temperature input and engine temperature input as well to be able to do some cold start programming and additional engine protection. However, transforming the signals into a form that the board can interface with seems like the major challenge. Around May I'll have a 617 on an engine stand. I have a couple cruise servos kicking around. I'll have a board of some sort. Let the games begin.
Oh, and BTW the MW IP for that engine is kaput so it will need new (larger) elements, thereby granting a means to test your theory about shadetree IP calibration
I don't expect results for YEARS.
EDIT: That's cool to hear that you are making progress 300SD81!! Definitely inspiring.
