My car was due for an MOT, but I couldn't be bothered to faff around under my car putting the original catalytic converter on.
So I hit upon the bright idea of flipping the A/B plug round to the 'B' side. I remember reading in TIS that switches the ECU into low noise/emission mode, required for certain countries that feel the C20XE is a bit 'noisy' lmao
Well, my car failed on emissions. But not as badly as you might think! Here are the results:
CO Level Limit 0.3%
HC Level Limit 200ppm
1st Fast Idle Test (2500 rpm)
CO Level 0.59%
HC Level 29ppm
2nd Fast Idle Test (3000 rpm)
CO Level 0.71%
HC Level 46ppm
CO Level 0.64%
IMHO, this ain't too bad considering the limits for a non-catalysed car are 3.5% and 1200ppm!
Just glad that I've got a free retest within 7 days
