So I had my remapped by from Revo stage 1 to stage 2 and the very next day I noticed that my cold starts have increased in length by probably around 10x for some strange reason:
Essentially the car idles @ 1100rpm for over a minute now with the exhaust making a hell of racket until it slowly drops down to the usual 900rpm. Now I'm not sure if it's just coincidental or if the map has resulted in this, but I did query this with Revo who stated that it's due to the decat and the increased time taken for the sensor to warm up without the catalytic converter in place to absorb heat generated by the "SAI" (Secondary Air Injection?).
The above would make sense, BUT I've had the decat in for quite a while and the issue only started recently (after the new map)
