Sec. 610.50  Test configurations.


    (a) In addition to the tuneup to manufacturer's specifications per 
Sec. 610.41, all vehicles in the durability fleet will have installed 
the following new parts: Air, oil, and fuel filters, spark plugs, 
points, condenser, rotor, distributor cap, PCV valve, and emission 
control devices such as vacuum control valves and EGR valves.
    (b) Vehicles included in the durability fleet will be subjected at 
zero device-miles to the same test sequence for fuel economy and exhaust 
emissions as specified in subpart D. Subsequently, they will be tested 
at 3,000 device-mile intervals, up to and including the final mileage 
point of 15,000 device-miles. Testing at these mileage points will be 
performed with the vehicle equipped with the full retrofit system.
    (c) After the 15,000-mile test the vehicle will be tuned as

and the vehicle set to vehicle manufacturer's specifications. A tuned 
baseline test will then be conducted.
