Evo IX emissions?
Discussion
So, in Colorado, after a vehicle is 5 years old, you have to get it emissions tested every year. This can be avoided by driveing through a certain number of roadside testing stations at certain intervals, a feat that this year sadly I failed to achieve.
As a result, I had to go to a emissions testing station. Which was comic in itself, as they only take cash, of which I had none on me, and the low fuel light was on.
After a quick stroll to the gas station to use their ATM, and another stroll back, with visions of hugely expensive failures looming, along with it running out of fuel pulling out of the test center, I passed.
Now, what was interesting were the actual figures.
For a start, the US doesn't use CO2 for taxation, so the Evo is set to run rich as standard, hence an almost comic CO2 gpm compared to UK spec cars.
What I'm wondering is, if anyone has any UK numbers to compare? I'm interested in seeing if the goal of chasing a low CO2 figure is at the expense of everything else, or if other numbers are comparable.
The form also has the required pass figures, and again I'm wondering if anyone can compare to UK testing - are these in the same order of magnitude, or just utterly laughably high, or low?
So:
Readings Limits
HC gpm 0.0817 1.2000
CO gpm 0.7941 15.0000
CO2 gpm 413.4955!
NOx gpm 0.0551 1.5000
Thoughts?
Not sure if this is the right place for this, but I figure it's probably the best location to get a response from another Evo owner. It might be worth mocing it elsewhere, mods, if you know of a better place.
