Finally a SM4 manual to download – Autronic MRM Forum

For a dumb ignition module with falling spark edge, with 4ms coil charge time, the SM4 ignition output will look like the following waveform: Set the line you want to graph to when graphing Press enter on selected item. Table properties Shows the table properties.

Variable camshaft control setup. Installing Autronic Software Step 1. At 76 degrees, boost is reduced by 20 KPA. Lower engine speeds means that the air will be effected by the water temperature in the manifold. Lets say that the basic boost pressure of our wastegate is 0. In the case of a turbo- or supercharged engine, pressurize the manifold pressure port of the fuel regulator top the maximum boost of the engine.

Launch control strategy – Manual transmission – SM4 – Autronic MRM Forum

When you are finished with your run, you can stop the logging process by pressing F8 again. Each injector in this list has been carefully mapped for the correct control strategy based on its electronic characteristics as battery voltages change. Once a suitable position has been located for the air temperature sensor a hole should be drilled and tapped to accept the sensor. The number of degrees BTDC the cylinder pulse trigger edge occurs.


No connection to -ve input pin allowed. Many late model engines already have provision for an exhaust gas oxygen sensor and the sensor provided should fit any standard exhaust mount. This is a good setup for an engine that has an active rpm range of up to about rpm, and with a rev limit at about rpm. Closed loop feedback idle speed control. Set to 0 to disable this function.


If to lean here, the engine will at first get way lean and hot when it gets back to the full power zone. Sometimes the static load condition is the worst case, and sometimes it is the dynamic, transientload case.

With the data log displayed move the curser bar use Left and Right arrow keys to any point in the data log where the ghost box on the fuel table autroic a RPM and Load axis.

Calibration range is 1. Can export to clipboard or printer. Tools and Material that you will need Installation of this SM4 system can be easily carried out sk4 professional mechanics and most experienced home mechanics if the following tools and components are available: Either over, or under the membrane.

Then stop the Autotune and copy this value to all sites in the fuel table other then your manua and start sites. Now you have a potentiometer that can be turned from 0 to percent. Maximum ignition timing allowed. The engine RPM below which over run shut down disabled. You can also weld an extra mount for tuning with an Autronic analyser. Over-run is deceleration with closed or very small throttle openings.

Use this setting to get a smooth boost line with minimum autrnic, then use the boost offset tables to correct the pressure and get a flat boost line. This is only shown to the 1st overlay file. We can also end up here when the throttle is temporarily lifted. The strategies for a built in wastegate are: Export to clipboard Sends page data to the clipboard.


Connect vehicle speed sensor and other inputs if used, like anti-lag, autrnic and more. This is shown as a yellow cell. Autronic systems have been successfully installed on many vehicles such as rally cars, off road vehicles, street cars, powerboats, offshore powerboats, and in other forms of racing.

A third type op pickup, the magnetic inductive is used in distributors as well as on crank trigger units. Even if the throttle is only half ,anual. The F4 key is the shortcut to this feature. If the injector you have in not in the list, consult you dealer for a recommendation of a similar injector to use. Turn off so that PC logging does not slow down when in tables. Connect O2 sensor if needed, f.

We leave the value at rpm since we got the boost pressure that we wanted at that engine speed. This appendix contains a lot of useful information about the different approaches to trigger design and is essential information to anyone installing the SM4. If table opened with same axis variables as logged data then an orange cursor shows the table position. Installation See wiring later in this manual.
