So my 93 didn't pass emissions this year, which is could be no surprise considering the NJ MVS folks were hitting the rev limit for over a minute. So now I have two weeks to figure out what could be the problem before it is illegal for me to drive around with it.

Besides the possibility of a faulty O2 sensor and perhaps the catalytic converter needing to be replaced (I dread that), I was wondering if maybe the ECUTune Stage One can help with emissions? The inspection report showed a HC ppm of 350 while the state minimum is 220 and CO% of 1.36 while the minimum is 1.20%.

Also, if I do buy the Stage 1, is the firmware up to date or do I also need to purchase the 2 8bit updated ROMs? In case you look at my last post and wonder what happened I ended up not getting a whole new catalytic setup and instead had someone who welded on a set of flanges on the rusted side, it seemed more reasonable to do that at the time but maybe I shall come to regret that.
