Many, many thanks to Andy, Chris and Kester at TOTD for managing to squeeze me in at very short notice this morning, to have the mapping adjusted on my car for it's MOT Emissions re-test today.
The guys, as always, were brilliant.

Chris spent about 45 mins playing with the tables and ended up with lambda 1.01 across the rev range for the MOT. Kester made me a nice cup of tea (Enjoy the Jaffa Cakes)

Just over an hour later at my local MOT centre the car passed with flying colours....

CO (max 0.20%): 0.00%
HC (max 200ppm): 4ppm
Lambda: 1.01

Hats off to you guys
