Skyline, I made a few modifications to my engine and need it engineered.
That's right clint32, but the amount of gas emitted is directly related to AF ratio too ( and a number of other things). If it's too rich.....more unburnt hydrocarbon = more emission. The ideal emission would be where AF= 14.7:1. Thus NA cars are cleaner than FI cars.
What I like to know is, who has done it before? If you past the test, then what AF ratio was your car at?
