Like the original, the new Rev/Speed Meter GP is a complete multi-function measuring device designed to measure and monitor data such as vehicle speed, engine rpm, and elapsed times.

However, the strength of the new unit lies in its differences compared to the predecessor. The most obvious difference is its completely redesigned look. This new aesthetically pleasing model was crafted to match the likes of other highly popular A'PEXi electronic devices, such as the V-AFC (VTEC controller), S-AFC (air/fuel controller) and the AVC-R (boost controller). The new screen utilizes the easy-to-read VFD (Vacuum Fluorescent Display) with a built-in light sensor for night-time viewing.

The new unit also delivers a host of new functions. Standard features include: engine rpm, vehicle speed, travel distance and battery voltage (all which can be displayed in real time graph mode, numerical mode or analog mode; 1-4 channels at a time). Peak/Hold, Replay (with 60-second playback), speed limiter cut, 0-100m/200m/400m times with trap speed, 0-100km/h/200km/h/300km/h times, mid-range acceleration (The user can preset any range of speed to measure). Stopwatch functions, best time memory, rpm warning, speed warning, rpm and speed outputs.

However, the most exciting new feature is the option to utilize the revolutionary A'PEXi G-Sensor. The G-Sensor allows the unit to measure g-forces in four-way front/rear/left/right directions. This data can be plotted in a graph display to map acceleration characteristics and lateral g on the race track or used in an array of new features, including 100m/200m/400m times with trap speed, wheel-spin correction, horsepower calculation and power-loss calculation.

By taking advantage of the optional G-Sensor, the user can produce extremely accurate power measurements. Usually, when measuring zero to-400-meter times through the speed sensor signal alone, the meter will end measurement too early (shorter distance) due to wheelspin.

Using the G-Sensor modifies the speed sensor signal, compensating for wheelspin and producing impeccably accurate acceleration times. With so many clever features, the A'PEXi RSM charts quarter- mile performance, engine output and lap times. The unit retails for $275. The optional G-Sensor is $65.
