Engine Protection Systems

Operating a fleet constitutes large investments and high risk. Engine or Gearbox failure could be very costly, not to mention the “down time” of the vehicle.
With the vast knowledge of our research and development team, Auto Tecnic have developed specialised engine protection systems to monitor all critical elements which would result in engine or gearbox failure.
Our engine management systems have been designed to “shut down” (manufacturers specification) the engine and protect it before further damage can occur.
With the versatility of our systems they can be used on all types of vehicles. i.e. Cars, bakkies, trucks, earth moving equipment, generators, air-cooled engines etc.

Our engine management systems are perfect for ensuring that your engines last the longest lifespan that they can, allowing for less down time and more time on the road or operating by protecting them from failure.

List of critical elements which can be monitored and protected by the engine management systems:
• Engine Oil Pressure
• Turbo Oil Pressure
• Engine Temperature
• Coolant Level
• Gearbox Temperature
• Gearbox Oil Pressure
• Clutch Abuse
• Fan Belt
• Dirty Air Filters
• Water Trap
• Brake Pads

Notifications of all the above alarms can be sent to nominated persons either via SMS, E-mail or on the tracking platform.

Please note that we can integrate with most tracking systems. However, the tracking system needs to be compatible to integrate.

Designing the Engine Management And Protection Systems.

AutotTecnic designs and manufactures engine management / engine monitoring systems for spark ignition engines intended for use in competition vehicles. All our systems are easily mapped and are very competitively priced. The systems are designed to be fitted to almost any engine. Usually on a modern engine the existing crankshaft and other sensors can be reused. If this is not the case then we provide a full range of temperature sensors, crankshaft sensors and wheels, pressure sensors etc. A number of multi-national motor manufacturers use our systems for longevity testing of their engine components because of their transparent ease of use and their ability to stress an engine outside its normal operating envelope.

Today engine monitoring unit products are controlled by the vehicle's on-board computer system with increasingly complex designs and parameters. AutotTecnic offers a full range of engine and vehicle management components including Air Mass Meters, Ignition Coils, EGR Valves, Idle Air Valves, Knock Sensors, Lambda Sensors, Crank/Cam Sensors, Switches and Sensors, Throttle Potentiometers and MAP Sensors. We also provide remote engine monitoring.


At AutotTecnic we specialise in full engine monitoring unit installations. We carry out a whole range of engine management projects, from fully mappable ignition system set-ups to a fully programmable engine monitoring unit system on a turbo-charged engine, with a vast array of programmable outputs and inputs - including variable intake cam timing and closed-loop wideband air-fuel ratio for the engine temperature monitoring system.

All engine management projects are carried out in three basic stages:


This involves working out the current limitations of the vehicle and its associated systems. Does the fuel system supply enough fuel for the intended engine performance? Are there any engine limitations that we are likely to encounter as we extract more performance? Will the existing running gear be adequate for the levels of torque we are likely to obtain?


This includes wiring in the fully mappable ECU to your existing engine loom. All electrical joins are soldered and heat-shrunk, and the wiring is protected with OEM automotive-grade electrical conduit. We supply high quality wiring looms to both public and trade.


Rather than simply downloading a generic map, we create and fine-tune maps specifically for your engine, in your car. This normally includes both road and rolling road mapping - using our state of the art AutotTecnic chassis dynamometer. Your engine is also repeatedly tested at a wide range of temperatures in order to fine-tune the idle quality.

We keep a wide range of engine management components in stock, including fully programmable ECU's, wiring looms, sensors and ignition components. See our Products page. Our engine / engine management wiring looms are made in-house to cater for both individual and trade applications. We also prove remote engine monitoring.
