A function that is inverted will be on even if the wire is not connected at all and when grounded off. Define your own calibration for IAC valve. This is a general purpose input so can be linearized to any scale. Boost modifier Boost modification.

The example shows that if the intake temperature rise above 65 degrees, the Boost setpoint will start to be lowered. Used for different boost maps on different gears, Traction control and displaying selected gears in the log. It does not have the ability to read the manifold pressure for correcting the fuel. Stoichiometric air fuel ratio. The standard Manifold absolute pressure sensor is continuous rated to kPa 29 PSI absolute and intermittently to kPa 64 PSI absolute, and is available from stock.

If incorrect do the same as above. It is also important to prevent the modules overheating by mounting it away from hot components such as exhaust manifolds and turbochargers. See manual under Software basic setup. When running the wiring for outputs, run any power and ground wiring to the locations where they will be connected, but do not connect power or ground the connections yet. This calibration table allows engine coolant temperature and engine “load” dependent control of additional fuel delivery.


CDI input and sequence 1, 2, 3, 4 and the output sequence the engine firing order.

Table properties Shows the table properties. This calibration function is only engine coolant temperature dependent and it uses the same engine coolant temperature calibration sites as chosen for the warm up enrichment calibration table above.

Ignition timing during initial RPM when starting. Enter for more pre-defined sensors. This is an advanced calibration.

The period of time before enrichment recommences after throttle is again depressed. How many sites used by table Maximum sites How many are possible Also shows if any axis is common to other tables. The Base Ignition Timing table should use load sites for pressure mapped engines.

Do not change values until base fuel table is fully mapped. The pressure that affects the wastegate actuator. 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.

Set the autdonic rate at which the ignition timing is allowed to retard. Soldering a crimped terminations can cause the wire at the crimp to become weak.

Makes it easy to import into a spread sheet program. Overrun ignition timing can have modifiers under “M2, Ignition trims”. It is important that these settings are selected properly, so be sure to consult your dealer for proper settings based on your manyal configuration.


The “IAC Actuator cal” will appear in the main menu. Operates any time TPS excides this value.

Autronica SM4 Manual

Locate a suitable position on the engine which will allow the hole and thread to be machined, and which gives access to the coolant stream. May be set for ‘semi-sequential’ operation on engines that have more than 8 cylinders e. Timing modes Timing range Resolution Accuracy. All are suitable for autroniv measurement or as switch inputs.

Crank/cam wiring question, SM4 – Autronic MRM Forum

The software will then show a pop-up box and maual you if you would like the ECU to fix the cells in the base fuel table that correspond to the highlighted cell in the mixture table.

Depending on where the air temperature sensor is position can effect the actual charge temperature of the engine. Forums Articles Autronic Webshop. For most engines this is the same as the number of cylinders.

Finally a SM4 manual to download – Autronic MRM Forum

The boost control has been tuned so the turbo will at most give a boost pressure around the wanted Boost setpoint, and well within the Over boost margin that otherwise would cause autronif boost cut to avoid damaging the engine.

Always wire them in firing order. Make large increases in table value. IAC-proportion range Idle air control proportion range.
