I am going to buy a wideband a/f ratio gauge. I have narrowed it down to an aem or autometer. What do you guys think of either??
I run an Altronics O2 Alert system. 480 bucks. Displays RPM, A/F, and Voltage in realtime and will datalog all 3 as well directly to the unit. I can play it back with out needing a lap top as well. I love it.
