These Innovate LM-3 AuxBox monitors attach to the auxiliary input of the
LM-1. They allow a user to log and analyze five critical engine metrics, in
addition to the air/fuel ratio native on the LM-1. They make the LM-1 into a
complete tuning kit, allowing the user to capture, view, and analyze data on all
six channels that the LM-1 can log internally.
Correlating AFR, RPM, MAP, and CHT, for example, is essential when tuning
piggy-back fuel controllers, ECU programmers, aftermarket ECUs, or racing
carburetors.
