I'm thinking of registering my 914 in Colorado, cars been running better than I ever remember, but I failed my e-check today. Visual inspection was fine, needless to say they couldn't fine anything on the car, but that also means they didn't see I have no smog pump or catalytic converter. I even passed on CO2.
But my HCs were 1825 at 2500rpms and 1047 at idle, 600 is the limit. And my COs were 11.7 at 2500rpms and 8.19 at idle, 3.5 is the limit. About the car. It's a 2056 running D-jet. I turned up the fuel pressure to compensate for the extra displacement, but I think that's how I shot myself in the foot. I'm also using SirAndy's old MPS. It's a 1.7 that he tweeked to run his old 1.8. My car loves it though. My car ran like shit with the 2L MPS, and it held vacuum and everything. I think that covers it. I'm thinking of turning down the Fuel pressure, leaning out the idle on the ECU and crossing my fingers. Any other ideas? Do those numbers seem way to far off to be cause by fuel pressure? Thanks guys. Samson |

If you just want to pass, run the gas down till the light comes on, add in a quart of denatured alcohol. Denatured alcohol is what is used in marine stoves as it has no CO emissions when burnt.
The downside is that the alcohol can mess with the seals and hoses if left in for any amount of time, so drive it home, drian the tank, fill it up and and go for a 30-40 min drive. I've never done this, but I've been told it works (IMG:style_emoticons/default/happy11.gif) |
