The car kind of revs itself very slightly for the first 10 seconds of cold idle when started, but I figured that was normal. Very short period of time and it cnsistently does it when very cold.
I believe that has something to do with the "cold start up maps" ... I think. reflashing the ECU with a fresh file might help. I know one member with the 625kit had this issue during cold weather, but we are talking about sub 0 degrees C. In any case, keep up posted on what you'll find out.
