Technical Information

 

The Engine Watchdog TM4 Twin Sensor Vehicle is used by professional racing teams for good reason –

  • TM4 Twin Sensor Vehicle uses the most reliable monitoring method
    All engines radiate heat to their outer casing at a constant rate (air cooled engines depend on it).The TM4's electronic 'Easy Fit' heat sensor simply fits like a washer under any suitable bolt that is close to the cylinder head or engine block or transmission housing. Here it accurately monitors the engine and transmission metal temperatures and if overheating is detected for any reason, the TM4 alarms with an alarm light, loud buzzer and 'Engine Hot' or 'Tran Hot' message.
  •  
  • The TM4 Twin Sensor Vehicle tells you exactly what's going on under the bonnet and in the transmission
    Many factory fit gauges indicate normal after you drive just a few kilometres and then do not alter on even the hottest days. Obviously the engine temperature is constantly altering as you drive in varying traffic and road conditions, yet the gauge is not responding. This is because they have a 'flat spot' around the normal mark and will not move until something is very wrong, often once it is too late. The TM4 has the sensitivity required to display every temperature change as it occurs and in an emergency will alert you before your existing dash gauge has even moved. Having the added advantage of monitoring your transmission temperature makes this unit invaluable for high performance and load bearing vehicles.
  •  
  • TM4 Twin Sensor Vehicle comes standard with the option to turn your existing dashboard oil light, into an'Audible Warning Light'
    If this optional wire is tagged to the engine's Oil Light Sender new messages will display on the screen. The new messages are: 'Engine Delay', this gives you time to start the engine before the audible oil alarm activates. 'Low Oil', this message and the alarm buzzer will activate instantly if low oil pressure is detected while you are driving. (Not suitable for oil gauge sensors. If you want this feature and only have an oil gauge, you will need to fit an inexpensive car type Oil Light Sender).
  •  
  • You can program the TM4's alarm sensitivity to suit your engine
    With a TM4 Twin Sensor Vehicle you don't even need to know your engine's temperature specifications to set the overheating alarm. You simply note the highest temperature your engine or transmission reaches during normal driving and then set the audible alarm to go off at a few degrees higher by pressing the button on the front. You get to set the alarm sensitivity and it's no harder than setting an alarm clock. If the alarm goes off while the engine is working hard, you can simply press the front button to stop the alarm, or give it another press to increase the alarm temperature. The engine and transmission alarm temperatures can be set independently of each other.
  •  
  • The TM4 Twin Sensor Vehicle is very easy to fit
    TM4's can be fitted by any home handyman. The main unit fits under the dash (Compact size - 80 x 30 x 60 mm, plus mounting tabs). The 'Easy Fit' temperature sensors takes a few seconds to bolt to the engine and the transmission. The power just plugs into the cigarette lighter socket or it can be hard wired to your vehicle's electrical system. TM4 suits 12 or 24 volt systems.
    For pictures and more installation details go to http://enginewatchdog.com and see the TM4 Installation Page.
  •  
  • The TM4's sensor cannot cause coolant leaks or transmission leaks, or void the engine's warranty
    The TM4 Twin Sensor Vehicle is perfectly safe to fit because it does not require you to break into the cooling system or the transmission in any way.
