Lean burn indicator
Introduction
More than a few EcoModders are big fans of Honda's very efficient lean burn engines, the miserly 1992-1995 Civic VX in particular.
The key to driving one of these engines efficiently, not surprisingly, is keeping them in lean burn mode. Some drivers can "feel" the engine entering and exiting lean burn, but for those who are new at it, or whose butt-o-meters aren't as sensitive, instrumentation is your friend.
EM moderator TomO has written a how-to for using a digital multimeter to monitor lean burn. He's also possibly working on an LED indicator.
Lean burn can also be set up on other standard engines by fooling the ECU by modifying the O2 sensor output.
