Hey i just installed my TT yesterday and i can't get it to work on the auto mode. I only hooked it to the ignition does it need to be hooked up to the o2 sensor in order for TT to choose the idle time automatically.
If I recall correctly, there are 3-4 wires that need to go to your ECU to get the necessary readings. This is why mine is still in the box in my trunk after 6 months. :O
