DESCRIPTION
The GTR Tacho is a self-contained electronic engine monitoring system
that displays RPM, coolant temp, oil pressure, battery voltage and also
with the option of up to 2 x exhaust pyrometers. The compact 3-1/8”
x 3-1/8” size is very easy to mount. The GTR Tacho’s extremely rugged
construction allows it to perform well in almost any racing environment.
The GTR Tacho recalls and displays the highest overall RPM and
gives total engine RPM, coolant temp, oil pressure and exhaust temp
(if exhaust temperature option is used) from the race start to finish in a
simple graph form. The Tacho works on 4, 6 & 8 cylinder engines with
either magnetos or distributors and is powered by a common 9 volt
battery or can be hard wired in to and 6-12 volt supplies with simple
wiring and sensor installation.
INSTALLATION
The kit comes with mounting wings that attach to the Tacho housing
with 4 x M4 x .7mm button screw and can be fixed to the vehicle with
2 x dzues fastners. The unit should be securely mounted in the cockpit
in a good viewing position and clear from interfering with any of the
vehicle controls.
