Please turn the cap locks off, my ears are hurting
. What kind of modifications have been done to your vehicle? I suspect that if you run denatured, it won't hurt anything. But if you were running a 50/50 mixture, you can stay with that. Since alcohol is a fuel, if you inject too much, it will drive HC and CO up and NOx down. What kind of boost has your car seen during the e-test. I suggest turning the alky on later than earlier, as this will attempt to help bring the NOx down. But still need some more info.

Even though all the other emissions came in, what are the specs and actual readings?
