From what I understand our state (Pa.) is going to do the testing from one of the diagnostic ports in the car. I can't imaging that would be very accurate on determining tailpipe emissions.lguerra1 said:I had to have an emmission test performed on my ride. I had the vehicle tested in stock form, passing with flying colors. I them had it rechecked after installing AR filter kit, 2.80 pulley, Diablo chip. The results were almost the same.
Stock Hydrocarbons 1.83ppm, could have up to 220.00ppm
Carbon Monoxide 0.00%, could have up to 1.20%
Modded Hydrocarbons 1.98ppm, could have up to 220.00 ppm
Carbon Monoxide, 0.00%, could have up to 1.20%
I only plan on adding a cat-back, so I don't think it will change much after that either. The key I believe is in the stock h-pipe. Once you change that out, the numbers will obviously change.
Also our test is only done at idle. There are many states that incorporate the California law, which are tougher.
I think they're starting to do that in IL as well... supposedly, they are just looking for codes in the computer from the O2 sensors... according to the pamphlet, it even mentions that they look for things that would cause the check engine light (MIL) to come on. So, wouldn't MIL eliminators do the trick for states with that type of testing?chillfactor said:Houston has some strict laws on emmision, but on the new cars and trucks they just plug into the port and off you go. I just did mine, had to change tags from New York to Texas, and I have a few mods....ha ha ha
Do we need to remove the chip when they connect to the port?
