...that cork-sucking IM240 emissions test. Yeah, that's the one on the fargin' dyno. Only took five tries.... :x :x :evil: :evil:
Ordinarily, I, like most people, would probably say, "So what? Big deal." The big deal is that my Ty is fairly heavily modified, with Vortec heads, 50 lb injectors, PT52 turbo, A2A IC, 180 degree thermostat and a bunch of other stuff. I got the truck to pass by simply tuning it -- no mechanical changes at all (already had a cat installed, came with the PTE kit).
My first time, hydrocarbons were too high, but everything else looked okay. As I leaned out the truck, the Nitrogen Oxides (NOx) got too high. So, I finally just pulled out over 10 degrees of timing all over (above 1200 RPM). That got the NOx down to the point where I passed. YAY!
So, this probably still isn't a big deal to most people, but I'm pretty excited. For one thing, it means I don't have to waste $450 on emissions-related parts to get a waiver. For another thing, I don't have to go back to the testing station for another 2 years.
P.S. I did it with a full tank of Sunoco 94, too!
