Hey Gang,
I've been eyeballing the CB Performance Air/Fuel meter to assist in dialing my carbs in. My eye is not well-trained enough to do it by looking at the spark plugs, so I though an A/F gauge might do the trick. It's about $130 for a three-wire heated O2 sensor, gauge, and exhaust bung. Anybody used it? Any others I should be looking at? I'd consider the Innovate unit, but it's over $300, and until I megasquirt, I don't think logging data will be that useful for my street only car. Also, as the car has dual carbs, would it be a good idea to weld in two bungs(or even four) so that I could switch between cylinder banks, or even individual cylinders? My thought is to mount the gauge in my existing clock (non-working) hole in the console. Any advice related to A/F meters and carbs is welcomed... Thanks!! --Jaybird |

If you have your jetting right, timing set properly, and fuel pump pressure right why would you need anything other than to get the airflow right to dial in the carbs? |
