High Nox

[jhanson1750]

I have read everything that I can find on high NOx and see that the EGR is where it is brought down. I have also seen that mixing alcohol to the fuel (up to @ 30%) will bring it down. I am wondering if this is refering methanol or alcohol? If meth then I dont need anything but if I need to get alcohol I will. Thanks, Jon Hanson

Are you running a catalytic converter?

Who's chip? sometimes chip makers turn off EGR function to make room for other modifications. You may also lower NOx with a slightly colder set of plugs
