Boost Configuration Menus Over boost margin, for Over boost time seconds, the SM4 will cut fuel to the engine until the boost pressure is down to safe values.

Never connect fuel injectors until the ECU is configured, otherwise the engine may flood with fuel. Throttle Position Sensor optional j. Parameter Boost setpoint determines which gear ratio that will select the Boost setpoint 3 table instead of any of the tables Boost setpoint 1 and Boost setpoint 2 in the same way that the parameter Boost setpoint works.

Analog channels can use these tables. Clear flooding throttle limit. Place floppy disk in A: The “L” and “K” keys switch between each tab. This is where we never should be able to end up. Eight injector drivers for full sequential operation on engines up to eight cylinders. The above list describes the capability on the current production revision of the product. Once a cell is tuned close to its accuracy point it will turn Yellow.

Use this setting to get a smooth boost line with minimum spiking, then use the boost offset tables to correct the pressure and get a flat boost line. Remote error indicator optional. Example of dumb ignitions modules: Which edge to trigger on.

The Input Trigger The SM4 is designed to trigger from either a square wave signal that varies from a low zero volt to a high voltage between 6 and 15 volt.


When you are working with exposed fuel, make sure you are working in a well ventilated environment. You can then just select the sites you wish to be automatically tuned. That is why the linearization table has no units. Under this menu you will select: See Edit-Window for options once file opened.

If your ECU model is not shown, ask an Autronic dealer for the version to use. Click on port using ie COM1 4. Accel recovery time Acceleration recovery time. Some wm4 are only available from some menus. Ideally the sensor should be mounted so that the throttle closed output voltage should be between 0.

For the SM4 to operate correctly a trigger edge must be generated. Rising and falling select this for Ford TFI trigger. If we want to use the Boost setpoint 1 auyronic on first gear, and the Boost setpoint 2 table on gears 2 and sn4, then set parameter Boost setpoint to a value in between the gear ratios of first and second gear.

Run the injector wires to the fuel injectors; Remember to wire them in ignition order, injector 1 to cylinder 1, injector 2 to next cylinder in firing order.

Sizing of instruments are on the bottom right of focused instrument. The manua, should be mounted after the engine and before the thermostat in the coolant circuit.

But still, we can end up here after selecting the wrong gear in a power shifting with boost pressure.


Have these connected janual attempting to start the engine. It is important that these settings are selected properly, so be sure to consult your dealer for proper settings based on your engine configuration. The system can be used with a large fixed throttle opening, or in conjunction- with electro-mechanical throttle by-pass valve or a throttle “kicker” solenoid. This break time is normally 0.


Rev limiter 1 Engine rev limiter. The strategies for a built in wastegate are: Disconnect throttle position electrical connector for at least 20 seconds. As curser is positioned over each cell the difference is displayed at the top of the window.

The actual voltage of this voltage is not important because it is from low-to-high or high-to-low that is used to trigger the SM4. A function that is inverted will be on even if the wire is not connected at all and when grounded off. This is a good starting point. This value is added to the base idle speed and stays active until the vehicle is under the moving speed and stays active for the Stopped decay period.

Setup this table after the boost controller is tuned and stable using the control range and dynamic comp settings. Login or Sign Up Log in with. When routing wutronic electrical system and connectors to the exhaust gas oxygen sensor do not allow the harness to touch the exhaust pipe, as heat will damage them. Before attempting anti-lag set-up it is most important that correct fuel and ignition calibration be achieved for “normal” engine operation.

But auutronic the boost control will always try to achieve the set boost pressure. aitronic

Crank/cam wiring question, SM4 – Autronic MRM Forum

This table, the engine “load”, barometric pressure and corrections dependent upon intake and coolant temperature, acceleration and deceleration and external trims determine the actual rate of fuel delivery for all engine operating s4m.

Short circuits on this wire can lead to fires.

Unpack your ECU and identify the following components, some components may vary if ordered a specific kit.
