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). You may find a better way but I used the existing bungs where the O2 sensors are now, entered a value of 13.4 in all A/F ratio cells to force open loop, and then tailored the VE tables to match the exhaust stream to read a global 13.4. Now once you match the desired A/F table to the exhaust stream, your VE tables are calibrated. Re-install the narrow band sensors back in place and set you A/F table back to what they were previously. From this point change what you want in the A/F map and the exhaust will follow what you entered.
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.
