Q: Can I connect the tach lead directly to the spark plug wire or directly to the magneto's wires?
A: No. This can cause incorrect tach readings, could damage the meter and can possibly cause harm to the user.
 
Q: What's the best way to install my tach lead?
A: The tach lead is typically installed by wrapping the lead around the plug wire three times and securing with a zip-tie.
 
Q: Why is my tach value jumping around?
A: You may have a strong ignition and it may be overpowering our receiver. You may want to try wrapping a piece of fuel line around the spark plug wire before wrapping the tach lead around it. You can also try reducing the number of wraps on the wire to 1 or 2.
 
Q: Why is my RPM reading lower than it should be?
A: If you believe that your tach is reading low, you may have a weak ignition source or the tach signal is being absorbed by ferrous metal surfaces (ex. steel). Try adding additional wraps around the plug wire or routing the tach lead away from ferrous metal surfaces. You may also want to try running the entire length of the tach lead inside a fuel line to prevent contact with metal surfaces.
 
Q: Does the Race Pro 3 work with transponder timing systems?
A: No, The RP3 only supports beacon (IR) and magnetic strip timing systems.
 
Q: Why is there no data in 'best' or 'session' mode after I complete my session?
A: In order for the RP3 to save data, the engine must be running with the tachometer being shown, the lap time must start counting after passing a timing source (IR or mag strip) and at least one lap must have been completed. When the data is being recorded the 'REC' icon will appear on the display. Make sure your RP3 is set to the proper timing input source; beacon ('bEAC') or magnetic strip ('StrP').
