Description The affordable V300SD data recorder is the most common recorder for Pro Stock, Pro Modified and many other Sportsman classes. In its base configuration, the V300 monitors six parameters (engine RPM, driveshaft RPM, accel G, lateral G, battery volts), but it can be expanded to monitor up to 67 channels of data to meet the needs of most users. Any monitored function can also be displayed in real time on Racepak’s IQ3 or UDX dashes. Datalink Standard software is pre-installed, giving the user the ability to record, download and perform telemetry (real-time) sessions, plus add math channels, custom run log pages and video integration.
