Updated first post with full article.
Innovative sounds like a good deal until you look further into the matter. You have to buy VERY expensive modules to extend its functionality.
I have zeitronix and my choice was purely practical.
Zeitronix can easily add more sensors which are very cheap as it already has all the cabling and terminals included in its zt-2 package. So far I have boost and fuel pressure hooked up and able to log in the software.
Additionally it also outputs analog AFR which is exploited by buying podi/whoever gauge and I now display real-time on-dash boost/afr information.
So in my book zeitrnoix is just better especially that it seems to be very accurate anyway, I don't know where they got 0.5 afr deviation. My car with perfect idling shows dead on 14.7 on zeitronix gauge.
More interestingly, if you wanted to cheat factory narrow band sensors you can also have zeitronix do that. Just read the manual and you might change you mind or at least not be so convinced innovate is such good product.
