Re: Confusing Smog Numbers

Well, I backed off the timing to stock(runs like crap now) and dumped a whole bottle of octane boost in it.  And somehow managed to pass.  1050 or so at 15mph and 350 or so at 25mph.  Basically EGR not engaging at all, but I managed to get a bit lucky.(the fuel additive did drop 300-400 off the NO reading, so without it I'd have been out of luck.

But the other issue is of course that HCs are right at the limit.  I guess it's to be expected given that this is La-La Land and the idiots in charge here make it impossible for any engine with over 150K miles to pass.(anyplace else the numbers would be more than acceptable - the engine runs very well normally.(have to set the timing back to 10 degrees tomorrow)

Probably the last time I ever smog it, though.
