The Illinois test equipment also requires 2500 rpm for the high-idle test, but
they use two sensors to detect the coil firing remotely: one is embedded in the
floor, the other is usually in a padded cover (dirty and caked with grit :-( )
which they plonk on your hood. The car registration file tells the computer how
many cylinders to divide its coil measurement by. Only if neither sensor can
detect the coil do they pop the hood and go for the #1 cylinder.

Illinois sets the standards for each car based on its mileage; fortunately the
standards are more relaxed for higher-mileage cars. For cars older than 1981,
the test is based only on low-idle emissions, which makes me wonder why they
bother going through the 2500-rpm runup anyway (low idle is tested before high
idle).
