Mirenco Launches New Speed Control Product

    RADCLIFFE, Iowa--April 1, 2003--Mirenco, Inc., (OTCBB:MREO) announces the launch of a new product aimed at improving safety and reducing driveline maintenance costs for electronic, diesel-powered shuttle buses, paratransit vehicles, and rental vans.
    The new product is PSC, which stands for Programmable Speed Control. PSC will give its customers control over a vehicle's rate of acceleration and top speed through a throttle delay that can be programmed with a hand-held computer. PSC improves safety for both drivers and passengers and reduces fuel costs at a time when diesel fuel is hovering at or near record prices in many parts of the country.
    PSC also could save thousands of dollars over the life of a vehicle by eliminating driveline maintenance problems, such as broken axles, universal joints, and differentials. PSC also will extend the life of a vehicle's engine, transmission, brakes, and tires.
    Mirenco believes the Programmable Speed Control will fill a niche market among diesel customers with a gross vehicle weight of 20,000 pounds or less. These vehicles typically have much more power than is necessary for that weight class, which often results in excess speed. That can lead to dangerous conditions for passengers and high maintenance costs.
    At first glance, PSC may appear to function like a governor. But PSC has some important distinctions from a mechanical governor. PSC works with electronic diesel engines, has multiple parameters that affect the rate of torque and top-end speed, and can easily be reprogrammed with a hand-held computer.
    "Mirenco is excited to launch the Programmable Speed Control. We are confident that this product will significantly improve passenger safety and reduce driveline maintenance costs," said Mirenco CEO Dwayne Fosseen.
