VAG ETC issues.
« on: October 19, 2015, 02:45:55 pm »
Friend is struggling with Audi A4 1,8turbo, with electronic throttle. VEMS+H-bridge ordered from webshop, connected properly (verified), all sensors (Pedal 1 and 2, TPS 1 and 2) calibrated.

When connected one way, throttle sort of works, but only when max dc% is set to 0% and min set to 100%. And it is oscillating during movement. When connected the other way around, nothing with either DC% setting.

Here are config files and logs:
