At Envirotest Systems Corp., we conduct vehicle emissions testing in the seven-county Denver metropolitan area. The types of testing we do include idle tests, IM/240 treadmill tests and RapidScreen roadside emissions tests. "Acceleration simulation mode testing" and "I/M 240 transient testing" are essentially the same, so we simply refer to it as the I/M 240 treadmill (or I/M 240 dynamometer) test.
