Alright, I'm running a my S4/S5 TII with the Microtech LT8 and wanted to start looking into getting a wideband O2 sensor so I can fine tune my a/f ratio to improve performance as well as gas mileage. I'm not sure what is the best for me though, do I need an $800.00 with a a/f with display or will a Bosch one from autozone do the job because the laptop shows the a/f. I'm sort of hurting on cash but if I need the best then you have to pay to play I guess.

 

Scroll down in this forum about 10-15 threads to one called 'Wideband Datalogging'. Several opinions in there (including mine).
