In order to reduce the number of wires that would be required to connect all of the digital / RPM sensors directly to the recorder (clutch, drive shaft, front wheel, or ring gear sensors, flow meter, etc.), Racepak
has developed RPM Modules to simplify and sanitize the job. The RPM Modules collect the inputs from the various sensors and then transfers the signals to the recorder via a single cable. RPM Modules are designed to mount on a tubular frame member.
