I can't seem to pass smog. Hi Nox. I was told that retarding the timing should bring the Nox down. I guess it is not adjustable.....85 325e. Thanx anyway....

Re: E30...timing retard

your problem is likely a lean condition which also raises combustion temps. to create high NOx, as might an engine running to hot. check all the engine air hoses for leaks then have a shop set the CO % as close to the rich spec's as possible, and no, your timing is not adjustable.
