question about stepper engines

[Tobi_XT]

Hello,
I search for a way to control a stepper engine with my ms2 with can
The stepper is for my AWD gear it is Electrically locked.
I hope anyone have an idea for my question.

Sorry for the Bad english I'm from Germany.

I don't believe the current firmware supports generic stepper motor controls, but if you could write up a detailed description of how the system operates, that would be helpful.

ok i try to explain it

at first this is my project an Vw Golf mk1 with 2.0 16v Turbo engine

it has at this moment over 540hp and an awd gear from an audi tt it called 4-motion.

This gear has an bipolar stepper engine that controls a little valve and this valve locks gradually the rear axle.
And i search for a way to control with the MS the blocking grade over the engine pressure and the throttle valve.
My first idea was an little board with an stepper control on board and get the data from the ms over can-bus, but i am not good enough to build such things like that

There are PWM to stepper converters out there, and Jean Belanger's TinyIOx has CAN communication as well as PWM output. That's where I'd start.

www.dutchbuild.com it looks like they make a haldex controller, you may have to contact them for more info. It may be able to interface with megasquirt.
