Bobthegod Anything you get from a chip is in your mind. Jeeps are very hard to get anymore power of. What you got is what you get. Don't even get me going on Diesel engines in California.....my company bought 50, 2009 engines since the engine manufacturers cannot meet the new specs for a diesel engine in California. We are presently testing Fuel Cell technology. We have three units at a cost $1.2 million dollars each. Any NEW vehicle we purchase now comes with an engine built in 2009, after they run out....who knows.

So you still want more power go here Hemi Conversions, Parts, and Kits by JSS and get yourself a Hemipower plant.

thompsontommy so would one of the aftermarket superchip or jet chip units really do anything to the computer that you would notice to improve the performance of a California Jeep?I know everyone is aginst the K&N cold air intake but I just got it delevered today and it's going in the Jeep first thing Saturday Morning.Loved the one I had on my Miata as far as extra dirt in the engine oh well (not too sure about that and put a little extra filter oil on it)

jeepjones I know it's off topic but Catepillar no longer makes diesel engines for commercial trucks because of california emissions laws.

Atthehop Some other states in the latter years have adapted CAL Emissions, NJ is one of them. The Feds will not allow another state to have their own standards, actually the manufacturers got the feds to stop it, each state can either have fed or CA. Where I work we but vehicles for all 50 states and have to have CAL emissions on a lot of non CAL states.

Bobthegod California has the strictest smaog laws. California has a tighter emmision regulations. the 49 other states (engines) can produce more harmful emmisions but in California engines have to produce less. CARB California Air Resources Board makes all the laws for California, the EPA Eviromental Protection Agency makes the Federal Laws.

#1 You can not modify, replace, remove any CARB required smog equipment from a car.
#2 You can only replace CARB required parts with other CARB certified parts.
#3 The only exemption is for homemade racing vehicles.
#4 An exhaust system that is installed AFTER the catalytic converter is considered
a "cat-back" system and is considered emissions legal.

Most smog devices are the same on most vehicles it's the emissions that in California must be lower then the other 49 states. How do they do it? Computer controlled tuning. This is why you see alot of aftermarket chips for sale.

Hope this helps.

flatline they pass because there smoged as a out of state vehicle. changing a california jeep to a 49 state computor would not pass. there kinda picky about that stuff here.

30-284 Same here my 99 is a Utah jeep and has passed every year with no problems.

pokey I could be wrong but I don't think there is any difference. My '99 just passed smog and was first sold in Ohio.

flatline the only diffrence I can see would be in the computor. I live in Ca (Yuk) but the jeep is a 49 state. all the emissions parts look to be the same between Ca/49 state. don't know if there's a big power difference. to change it you should just be able to put a 49 sate computor in. If you live in Ca you wont pass smog.

California emissions question

Does any one know what the difference is between California emissions and everyone else's is?How does it effect engine performance?Is the engine detuned?Any way to change it?
