AUTRONIC SMC PLUG AND PLAY 

The Autronic SMC Sequential Engine Management System is a compact engine management control for all engine performance upgrades. We love the SMC on any application, but the plug and play board for the subaru is an awesome option for any subaru fan looking to control big hp setups. 

Autronics user friendly Windows software allows us to select the degree of sophistication required for each application. This program, in combination with intelligence within the management system, allows us to select the finest calibration detail required to match the application, in absolute minimum of time.

This program provides the means of interrogating the engine management system enabling speedy diagnosis and calibration.

Usage.
These systems can cater for the requirements of virtually any spark ignition engine, including the following.
i. High output supercharged or turbocharged engines, with either multi point and/or center point injection.

Features.
1. a. Eight injector drivers for full sequential operation on engines up to eight cylinders. May be set for 'semi-sequential' operation on engines having more than 8 cylinders. e.g:- 12 cylinder engine using 6 groups of 2 two cylinders.
b. All injector types catered for (0.9 ohm to 16 ohm coil resistance). Specify unit fitted with optional high current injector drivers for 0.9 ohm or twin injector applications.

2. User choice of manifold absolute pressure or throttle position as engine load input. Internal absolute
pressure sensor for simplified installation 0 to 200 kpa (0 to 29.4 PSI) and 0 to 300 kpa (0 to 44.1 PSI) available from stock. 0 to 450 kpa (0 to 66.1 PSI) available on request.

3. Single coil distributor, twin coil distributor or muilticoil distributor-less ignition configurations are possible on most engines.

4. Fitted with environmentally sealed connector the standard unit is splash proof. Units are available with double environmental sealing for use in the most arduous of applications (e.g:- rally, off-road and marine).

5. Auxiliary output function that can be used for any of the following:
i. Closed loop (feedback), boost control for turbocharged engines with rpm and temperature dependent calibration characteristic.
ii. Closed loop (feedback) idle speed control.
iii. Control of engine cooling fan.
iv. Programmable on/off control for solenoid or relay driving that operates according to engine speed and load (eg:- can be used for gear shift control or light, over rev indicator, inlet camshaft timing selection or control of a supplementary electric fuel pump that augments mechanical fuel pump delivery at low engine rpm only).
v. Fuel used pulse output to electric or electro-mechanical counter with resolution of 0.1 liter (or use with trip computer).
vi. Or even more sophisticated control function such as servo control of auxiliary butterfly for turbocharged applications requiring precise throttle control and minimum turbo lag.

6. Exhaust oxygen sensor input for sensing air/fuel ratio. Connect either a Bosch narrow band O2 sensor or for more demanding applications a Bosch wide band O2 sensor and Autronic Analyzer. The low cost narrow band sensor requires no interface adapters or expensive air/fuel ratio meters, and offers moderate accuracy and tolerance to leaded fuels. This function can be used to monitor air/fuel ratio during engine tuning or can be used for feedback control of air/fuel ratio for applications requiring exhaust catalytic conversion (feature available on request).

7. Diagnostic/Error indicator of sensor or ECU fault conditions with memory for detection of intermittent fault conditions. An external light may also be connected for remote indication of abnormal operation.

8. Precise spark advance control strategy for both static and dynamic operating conditions.

9. Unique calibration strategy allows accurate control of fuel delivery under both acceleration and deceleration.

10. User selectable spark and fuel delivery strategy for abnormal engine operation conditions to minimize possibility of engine damage whilst still maintaining engine operation.. (eg:- over heated or over boosted).

11. Comprehensive limp-home functions with user selectable default settings that ensure engine operation can continue after sensor failure has occurred.

12. Full compensation of engine control parameters for engine operation at any altitude (fuel delivery, ignition timing and boost pressure).

13. Adaptive learning (with memory) to minimize the number of user setups required and to provide optimal control of air/fuel ratio, boost pressure and idle stability.

14. Rev limiter with soft characteristic that uses a combination of fuel delivery and spark control.

15. Fuel pump safety shutoff. Pump stops 3 to 4 seconds after the engine stops.

16. Unit is ultra light weight/compact yet has sufficient drive capacity for high power continuous duty applications. (one unit OK for all applications from motor cycle to large capacity twin turbo engines).

17. Optional interface unit to allow sequential operation without the need for separate crank/camshaft sensors or special multi-sensor distributor.
