Thanks for update
Thank you for update, so i see more into this problem now! Looking at your post i basically see two options:
1. If you'll succeed with your current attempt, i am already sigining in for installation into my car! I don't need dynamical control, but riding long distances on higway with speed limits without even a possibility to put down the leg from pedal is driving me nuts!
2. If you won't, then i am giving up and look for new car.
I'll keep close watch on this thread, so please, keep it posted with some news you might have, i'll really apreciate this.
