Woo hoo! No more emission tests!
The Illinois EPA is doing away with emission testing for vehicles built before 1996. The reasoning is that they're maintaining expensive exhaust analyzers and chassis dynamometers to test a dwindling number of vehicles. For newer cars they just plug into the OBD II and read the computer memory.
That means that I can now tune the Jeep for better mileage. In the distant past it has gotten 18MPG on the highway, but with the ignition advance set for low emissions it only gets around 14.
And before someone jumps me about social responsibility and polluting the air, I'll point out that my Jeep typically is driven a thousand miles a year or less. Considering the pollution not created by extracting, refining, shipping and dispensing additional gasoline, the contribution of airborn pollutants will be insignificant.
Anybody want a used chassis dyno, cheap? There should be a bunch of them on the market soon. [img]/ubbthreads/images/graemlins/grin.gif[/img]
