A/F Ratio

Having installed an A/F ratio meter (with similar LEDs), I can say that's it nearly worthless.

This was on an '03 Evo -- the LEDs would be consistent only in open loop: cold start or full-throttle. The closest use was A/F at full-throttle, full-boost (in those driving situations, a quick glance) to see if a lean situation was apparent (rare if ever).

Otherwise, the meter bounced back and forth under normal operation.
