The wideband is worth the $$$$ - you could get the lower cost LC1 for $199 but the A/F ratio gage is just so cool and useful too.....

With the wideband you set up the desired A/F ratio at each of the table vertexs and then drive while data logging. Take the data log run it through megalogviewer optimization s/w (runs on the laptop) it read the log file and adjusts the VE table for you. You then load the new VE table and go for another drive while logging and repeat the process 2 or 3 times and poof you have a good base tune up.
