Any suggestions?
There are so many to choose from but I settled on the Innovate Motorsports. Their reputation & products seem to be pretty good. Whichever company you choose, you may want to consider getting a dual channel model with a pair of wide bands so you can monitor both front and rear at the same time. You will be surprised how different each cylinder really is from each other and how you really need to look at each cylinder as being a separate and tunable engine.
Because this system does not use a vacuum pump to draw the sample from the tailpipe, probing at the exhaust tip will lead to very inaccurate readings. I even purchased their patented exhaust probe adapter which did not work at all (that just saved you $80
Also think about getting the optional o2 sensor heat sink accessory(s) since the Bosch wide bands have an upper limit of ~1K F* and in my case the sensors were close to the exhaust port.
As you can see, don't even go down this road unless your ready to invest both lots of time and money. For me it was worth it because I just got fed up with all the mis-information out on the street about this topic.
