Just had mine set up with a VERY quick map, as tps went tits up.
CO was 2.25%, and falling and it runs perfect, and was NOT on closed loop either as not enabled yet.
There is no need for these high emissions, and if due to mapping it has been a shit job, are you sure the car was FULLY warm, let the fan cut in once just to make sure, or you may have a dicky cts.
