[Fot] Dual AFR gauges

[Jim]

Well, it's been an interesting afternoon, both on list and off.

Sounds like putting in a new sensor every season (or two) on an AFR is good
enough, even on a car running leaded gas.

I appreciate the input both on list and off.


Cheers,

Jim

O2 sensors get poisoned but it's slow. In a racing engine your rings will
have a shorter life.
