The Rev/Speed Meter GP's dot matrix display adopts the highly successful & bright blue VFD (Vacuum Fluorescent Display) from the popular AVC-R & S-AFC products. This display allows various modes of information to be displayed simultaneously in numerous ways:.numerical; graphical; and analog.. All information is displayed accurately and clearly. Product size is at a slim 52 mm x 126 mm x 18 mm & can be mounted anywhere in a vehicle cockpit. Multiple function buttons are eliminated with the incorporation of a single navigational rocker & push button providing ease of use. Measures a vehicle's engine RPM; speed; and distance traveled. It also displays battery voltage (in real time) in three different modes: numerical; analog; and graphical. Peak values are also displayed in all three above-mentioned modes & playback can be displayed graphically. It can measure the speed achieved & the time elapsed in 0-100m; 0-200m; 0-400m runs Vice versa it can measure the time elapsed for 0-100km/h; 0-200km/h; & 0-300km/h. With time taken to achieve a vehicle's top speed intermediate acceleration can be measured. It records & stores the 5 best values of each function. Turning the power off will erase all values recorded if not stored in memory. Initial settings in the EEPROM will not be eliminated when the battery power is removed. Removal of battery will also will not eliminate the best 5 values stored. Removal of a vehicle's battery will not eliminate any information stored in memory which ensures that initial settings are not required to be reset. When setting RPM function the output switch is loaded once it reads engine speed. For example: with readings from vehicle speed it calculates & displays RPM depending on vehicle's gearing. The RPM reading can be set to activate a shift point indicator light & even to activate a scramble switch of a boost controller. It is applicable to newly released Honda models with automatic transmissions& to Toyota models where speed cancellation is difficult to overcome.
