Autronic
Autronic is a fuel-injection company located in Victoria, Australia. Richard Aubert, a former partner and one of the original founders of MoTeC, started the company on his own in 1987. Since then, the company has remained fairly small, but has been producing some of the finest fuel-injection systems in the world.
Autronic is an Australian company well known for their extremely high-quality engine management systems. They currently have two versions: the SMC, shown here, and the SM2. Autronic systems are known for their user friendliness as well as their extreme reliability. Their Auto-Tune software allows users to set parameters for the ECU, which then self-calibrates the engine with no other input from the tuner.
When the company’s sales began to grow too large for one man to handle, Richard enlisted the help of Ray Hall Turbocharging in Cairns, Australia, to handle worldwide product distribution.
From there, Ray set up distributors for Autronic in dozens of countries all over the world. The reputation for quality and reliability grew quickly and word began to spread that there was a new contender in the high-performance fuel-injection market. One country that was still relatively untapped was the United States. To gain market share here, Ray Hall teamed up with Steve Nichols from Aussie Imports, LLC in Lexington, Kentucky. Steve Nichols took charge of the distribution for Autronic products in the USA, and quickly began building a large base of dealers all over the country to sell and support these units.
Autronic systems are all supplied with a user’s manual, wire harness, and the necessary sensors. The user needs to connect the harness to the sensors on their particular application.
Currently, Autronic produces several versions of their ECU. The first is the SMC, which is a compact and sporty version packed with features like fully sequential fuel injection, ignition timing control, boost control, on board data-logging, and a host of other features we will talk about later. Next comes the SM2 model, which is geared mainly at the racing segment with its multiple stages of boost control, two stage rev limiters, anti-lag boost functions, traction control, and flat-shift options. Both of these models are extremely flexible and can be configured to operate nearly any internal combustion engine from 1 to 16 cylinders in both two-stroke and four-stroke configurations. They even work for rotary engines!
The Autronic systems are only designed to recognize RPM and camshaft position signals from Hall-effect-type sensors. Luckily, most OEM applications use this type of sensor.
Autronic also produces several plug-and-play units that are designed to directly replace the factory computer with no wiring and fit inside the factory ECU case. These models support the Mitsubishi Evo family, the Subaru Impreza WRX line, and most of the early second-generation DSM series of automobiles (Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser). These units are designed to handle all of the functions the factory ECU controlled, plus give the user full programmability over the fuel, ignition, boost, idle, AC functions, and more. The units also have anti-lag functionality, two-step rev limiters, and flat shift on board. Flat-shift is an option that cuts the ignition system during gear changes, which gives the driver the ability to shift faster and keep the gas pedal flat on the floor.
Autronic produces several plug-and-play versions of their ECU for engine such as the Subaru WRX shown here, and also for Mitsubishi EVO sports cars as well. These systems use the factory harness and all OEM sensors.
When you order an ECU from Autronic, the kit includes:
• ECU
• Harness (open ended with no terminations at sensor end)
• Data Cable
• Interface Software
• Water Temp Sensor
• Air Temp Sensor (Autronic specific)
• Fuel Pump Relay
The current Autronic systems are only designed to recognize RPM and camshaft position signals from Hall-effect type sensors. Luckily, most OEM applications use this type of sensor. For vehicles that use older VRT or magnetic sensors, you will need to fabricate new mounts and replace them with the Hall-effect sensors available through Autronic.
The current Autronic ECUs can control as many as four ignition outputs at once, however, they’re not equipped with dwell timing to fire ignition coils directly. The output wires must be connected to either an ignitor, such as the units available from Bosch, or to a CDI unit such as MSD, M&W Ignitions, or the awesome Autronic 500R CDI.
The Autronic 500R CDI can provide enough curretn to meet just about any spark requirement that exists!
The Autronic 500R CDI, or capacitive discharge ignition unit, is by far the most powerful ignition system anywhere in the world. Not only does it have superior firepower to keep the spark plugs lit under any circumstance, but it is the only unit available anywhere that uses twin dump capacitors. Although other units, such as those from MSD and M&W, will get the job done, they simply cannot keep up with the 500R’s ability to fire at full energy even at extremely high RPM. This ability is the result of its having double the capacitor storage of the other units. Also, since the 500R was designed specifically for Autronic ECUs, you are virtually guaranteed to have trouble-free operation and compatibility.
Other options that the Autronic systems can be ordered with include:
• IAC Solenoids
• Wideband Oxygen Sensors
• Boost Control Valves
• Air/fuel Monitors
Autronic also manufactures their own Telemetry systems, which allow the user to communicate in real time via radio modems to the ECU even when the vehicle is as much as two miles away! This allows the tuner to monitor, display, and adjust the maps in the computer while the car is off racing around a track somewhere. You can also control the data-logging functions and use all of the benefits in the software package at any time!
With the Autronic Telemetry system, users can see all of the same data used in the calibration software, as shown here. You can view, change, and data-log information in real time from distances up to two miles away! This can come in handy if you want to tune the engine while someone else drives it (or vice-versa).
