Autronic Smc V1.92 Autotune Ecu *reduced Price!* on 2040-parts.com

Works great.  Pulled from race car in 2010 and stored.  Communicated with laptop and pulled down old tune (4G64 DOHC Turbo @ 1bar) last week.  MAP sensor (internal) replaced in 2005.

Comes with

• Autronic SMC ecu V1.92 chip (standard case)
• Original Manual from Ray Hall Technology ( Software and Manual available online: http://www.mrm-racing.se/index.php?pageid=SMCe )
• Used un-terminated harness wires various lengths.  Easy to replace wires individually.
• Autronic Air Temperature Sensor
• Long Serial cable with 1/8" headphone jack

Serial Number: L5492T2A4/2 

T2 = 3.4 bar map sensor (4.4 bar absolute)
A2 = Low current (high res) injector drivers... (see below)

SMC serial number 5387 or higher has a new injector driver that can use a jumper to select high current or low current drivers. There are three jumpers close to drivers to make them Low current, add the jumper to make them Low current, for high current remove the jumpers.  NOTE: No dwell board (you need cdi or ignitors... see manual).

The Autronic SMC is a sequential 3D ECU.  Compatible PC or Laptop serial port. Have tested the software on a Windows 8 laptop with with USB to serial adapter.

Dimensions:

L = 150mm (6 inches)
W = 120mm (4 3/4 inches)
H = 35mm (1 3/8 inches)

Features:

• Sequential operation for 2 to 8 cylinder engines and non sequential operation for 10+ cylinders
• Eight injector outputs
• Four ignition outputs
• 3D fuel and ignition maps
• User defined up to 32 RPM and 16 Load sites = 512 sites
• Anti-lag
• Flat Shift (ver 1.19)
• Data Logging
• Software selectable trigger angle
• Support for multi-tooth or missing teeth triggers
• Auxiliary outputs other than fuel pump control
• 8 cyl engine = 1 (1 PWM output)
• 6 cyl engine = 3 (1 PWM + 2 On/Off)
• 4 cyl engine = 5 (1 PWM + 4 On/Off)
• Auxiliary outputs can be defined for boost control, nitrous oxide, camshaft timing, AC, fan control, idle valve etc.

Single coil distributor, twin coil distributor or muilticoil distributor-less ignition configurations are possible on most engines
Exhaust oxygen sensor input for sensing air/fuel ratio

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

• Precise spark advance control strategy for both static and dynamic operating conditions
• Unique calibration strategy allows accurate control of fuel delivery under both acceleration and deceleration
• 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)
• Comprehensive limp-home functions with user selectable default settings that ensure engine operation can continue after sensor failure has occurred
• Full compensation of engine control parameters for engine operation at any altitude (fuel delivery, ignition timing and boost pressure)
• 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
• Rev limiter with soft characteristic that uses a combination of fuel delivery and spark control
• Fuel pump safety shutoff. Pump stops 3 to 4 seconds after the engine stops
• nit 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)
• Optional interface unit to allow sequential operation without the need for separate crank/camshaft sensors or special multi-sensor distributor
• Optional Water Proof case for marine or harsh environments

A user friendly Windows software allows the user to select the degree of sophistication required for each application. This program, in combination with intelligence within the management system, allows the user 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.

These systems can cater for the requirements of virtually any spark ignition engine, including the following:

• High output supercharged or turbocharged engines, with either multi point and/or center point injection
• Rotary (Wankel) and two stroke engines
• Engines having uneven firing sequences such as 2 and 4 cylinder "V" configuration motor cycle engines and V6 motor vehicle engines

IMPORTANT:- Please note that this product is intended for high performance motor sport applications and compliance with statutory regulations when used on public roads cannot be guaranteed.

Auxiliary Output Function can be used for the following:

• Closed loop (feedback), boost control for turbocharged engines with rpm and temperature dependent calibration characteristic
• Closed loop (feedback) idle speed control
• Control of engine cooling fan
• 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)
• Fuel used pulse output to electric or electro-mechanical counter with resolution of 0.1 liter (or use with trip computer)
• Even more sophisticated control function such as servo control of auxiliary butterfly for turbocharged applications requiring precise throttle control and minimum turbo lag

Inputs:

• Ignition input Hall effect, (Also available for direct connection to magnetic reluctor type pick-ups)
• No. 1 cylinder reference. (Also available for direct connection to magnetic reluctor type pickups)
• Barometric pressure 3.4 bar (included)
• Manifold pressure
• Throttle position (TPS Sensor not included)
• Intake air temperature (included)
• Engine coolant temperature (not included)
• Exhaust oxygen (Sensor sold separately)
• Idle mixture trim. (Internal to ECU and screwdriver adjustable from outside)

Outputs:

• Open collector ignition output to any of the following:
• Single coil high energy ignitions: Bosch 7 pin, Mitsubishi 3 pin
• Autronic Capacitor Discharge Ignition (CDI)
• MSD 6A etc.
• Auxiliary Outputs:
• Fuel pump/injector fuel shut off safety relay
• Multifunction on/off or pulse width modulation output for either:
• Engine cooling fan relay
• Idle speed actuator. (Variable duty cycle single pole type, eg:- Bosch)
• Turbocharger wastegate control valve. (SEM, most OEM types or Autronic low or high capacity)
• Turbocharger auxiliary butterfly control motor
• General purpose duty cycle output with user define characteristic
• Fuel used pulse output. (for trip computer function)

Wire in standalone systems such as the Autronic's require considerable knowledge to install and properly tune. Support forums: http://www.mrm-racing.se/
