The CEL is still lit with the dummy plug. I called RC and they said remove the complete harness and see if it goes out. If it does, the harness is faulty (from heat, moisture, vibrations, etc) and if needed, they would replace under warranty.

At the same time, I shared my setting with the rep and he said that was too high and not recommended. I've spoken to this rep in the past and discussed what could be done, but never heard him say a setting was too high and not recommended. He asked that I reduce S1 to 1 at least, and even better, back to stock - 0.

I asked if they ever followed the BMW forums and he said they did, but they no longer get involved in discussions - too many opinions and he said, as a manufacturer, they never prevail. Even though it's their product. He said therefore, the only official recommendation is the setting it shipped with. To which I said, then why the setting choices??

Anyway, I am more concerned about getting rid of the CEL right now.
