Hi guys and greetings from Slovakia.
I am planning to use your controller in my Smart roadster. In stock it produces 60kW and it is a turbocharged 700ccm 3cyl. engine. I am currently building a mix of a 800ccm CDI lump and a 700ccm petrol head, wich at this moment is up and running. But the smart has a pretty pain in the ass motorised manual gearbox, wich clutch is engaged witch a servo actuator and gears are selected with a stepper motor connected to a coding drum. How about to control this little toy? Will there ever be a possibility to add this gearbox control? Now what i plan to use is "co-install" your controller in parallel with the original MEG 1.1 (by the way the meg is running on C167 and controlling engine and the gearbox").

hello and welcome!

We need to see what kind of logic would be needed, once we know what we need I can definitely add some logic for gearbox control especially if it would be generic enough. See also http://rusefi.com/wiki/index.php?title=Manual:Flexible_Logic

Wow, that was a fast answer.
Its interresting, looks great, it seems like a script interpretter, wich in this case of design gives the user pretty much power to do tasks. In next few Days i write down the pinouts and wiring for the gearbox. (The MEG runs a PID to controll the clutch drag point. The gear selector is a simple closed loop servo with stepper and a feedback potentiometer). Before i heard of rusefi project i had in plan to make a simple standalone electronic "gear selector" and to controll the cluth by wire, but it is a lot more effort as to use the current factory setup. (for the motors, the motors are not steppers in the right meaning, there are just DC motors with hall encoders on their shafts producing a phase shifted signal for the controller).

Now i printed the full wiring schematics for the car, but it is in original Mercedes WIS wirings. I printed a TIF out of it, but beware the tif file has several pages in it. I will convert it to a little table with PIN no.,color, signal name and where it goes. Here are the printouts from WIS. One document is the MEG connector that goes to chassis harness, another document is the motor connector wiring harness.

Any chance to see a picture of your board?
