Honestly.. the plug question is a good question that i should double check.

I've run this same exact set up with not changes other than the ecu, without issue for about a year now. All I did was change out the ECU (w/ ecmlink obviously), and here I am.

I'm fairly positive it has to do with settings on ECMLink, as I'm quickly realizing as much as i thought i knew about tuning and what not, ECMLink has me nearly baffled with all the options.

Regarding Firebird's post, i was looking at my OpenLoopMaxOct table, and it seems to be running in the WAY rich area of the table. Not to mention the Estimated A/F from the table does not match my wideband.

how do i adjust the OpenLoopMaxOct table the right way to better align with my setup?
