A brand new holden wont pass the new emission standards the EPA is to bring in ROB_RA40. Japanese emissions testing is alot less stringent than ours. Did you know when they test their cars instead of checking emissions from when the car is cold(when emissions are at there absolute worst) they pre-warm their cars to operating temperature and then test them. That's exactly why as Frankie says the new RX7's don't pass our emissions but passed Japan's comfortably. An aftermarket ECU tuned to pass an emissions test will do it far easier than a standard ECU is what i'm also saying. Cause you can tune it with AF meter to get spot on 14.7 ratios. Standard ECU's wont ever give you 14.7 in the test situations you undergo. Because the factory ECU's want nice crisp acceleration and smoothness which comes with adding fuel and ratio's down towards 13:1(with this also comes massive increases in CO-Carbon monoxides) For the purposes of the test, you take out all that smoothness and crisp acceleration and set it for 14.7:1 af ratios. You'll have a better chance at passing with the aftermarket than the factory. Draven, i'm going to make my own wideband kit shortly which will be great for AF monitoring(costs around $400). Best to do the first tune on the dyno as you can measure the power increases and get the torque curve as high as possible for the longest possible length of the graph. Hornsby prestigue and performance do great tuning cheap, you gotta do it with the dyno for power purposes then you can do cruise maps etc on the road. [Report message to a moderator]
