The PRO IIIA Data Recorder is a downsized version of the PRO III. It is designed for use in a variety of categories from Alcohol Dragsters and Funny Cars, Nostalgia Top Fuel Dragsters and Funny Cars, and other supercharged applications that use high amperage magnetos with extreme cylinder pressure. Its rugged construction makes it ideally suited for vehicles that encounter severe tire shake.
The PRO IIIA provides the basic functions required by all applications (engine RPM, drive shaft RPM, 8 exhaust gas temperatures) and also includes the ability to monitor ignition timing while having the capability of being expanded to suit each userís individual needs. It can handle other digital channels such as clutch RPM and flow meters, plus up to 16 analog channels. The PRO IIIA also supports the popular Pro Dash, a programmable onboard real time display dash.
