What are the modified exhaust laws in your state? Smog laws? Do you have a CEL on? When was your last tune up? How is your timing? etc etc.

just got back from doing the test, and i failed.

Cruise Emmisions:
HC(PPM) - 517
CO(%) - 9.6

I'm too lazy to go to a mechanic right now, so please can you guys help?

We need WAY more info on the whole setup, mileage, CEL, etc..

The operator just told me to take the Emissions Report to a mechanic, and he'll know what to fix, so i was assuming you guys would do the same?

I know nothing about this car, and the milage of the motor.

But its a single zc vtec with a vx ecu.

I've once ran a stock P28 ECU in the car, and it ran much smoother, could that be one factor?

whats the max and measured readings?

In this picture, you'll notice on the left (richer mixture) your CO and HC go up. Normally if you make more power, your mixture leans out. But that assumes you use the correct ecu. A ZC VTEC motor is the same as a z6 or y8, and the VX ecu is for a VX head that runs one valve almost closed before vtec. Run the correct ecu (p28 is best in this case), and it might be better. You should also run a stock cat and a new o2 sensor, if you want it to pass emissions.
