This is the best price I've seen on the A/F ratio package in the past year. The gauge alone is typically $200! I have no idea how long this price will last.... I just received an e-mail from Amazon today. http://www.amazon.com/dp/B001QFDZU0/ref=pe_58340_15981150_pe_vfe_d8 Don't forget to select the 'Super Saver' shipping option for free shipping! The XD-16 gauge's most useful feature over a standard display is the pushbutton on the face used to start/stop datalogging runs. A laptop will need to be connected to record data. .....And to connect a laptop, you will also need to buy a serial-to-USB adapter cable, unless your PC has a serial connector (I doubt it) :TU:
Hey, this one is a darn good deal as well. http://www.amazon.com/Innovate-Motorsports-3806-Digital-Wideband/dp/B001QFL8KE/ref=pd_sbs_auto_5
