went to see them at phoenix today, they wanted me to disconnect my traction control.
They showed me on their diagnostic box which can read the lambda voltages. The car functions correctly when cold, e.g. ajusting between slightly lean, slightly rich. It seemed to idle in the region of 30mV.
But when we went for a run, engine gets warm, it turns into permanently rich, constantly running at about 700mV.
We still don't know what's wrong, he said he will try a few more things over the next few days 🙁
