Autronics sm4 software

This is the biggest selling model and is suitable for most applications. The basic Autronic SMC kit includes harness, air temp sensor, internal map sensor, fuel pump relay, PC data cable, calibration and data logging software, and page manual.

The internal map sensor is available in 4. Available with high current low impedance or low current high impedance injector drivers. Harness has a connector which plugs into the Ecu, and has a socket for fuel pump relay, and socket for data cable connection to a IBM compatible PC or Laptop.

How well can they be tuned for good economy? Posted March 12, edited. Does The autronic map fuel with seperate maps for each given RPM vs manifold vac, like the microtech matrix mode?

They don't have closed loop idle, simply because N I B Posted March 12, CruiseLiner Posted March 12, A lot of people who run an Autronics ECU also have larger cams, let alone all the V8 boys who run even bigger cams.

First, the SMC has eight individual ignition outputs, none of which provide any dwell.

The software allows many different ways to set all this up, but basically for a six cylinder engine there are three alternatives. This one ignition output could also trigger an external CDI unit. Obviously a distributor cap and rotor button will be required to fire six plugs.

Now suppose your ignition fires 15 degrees BTDC in cylinder 1. Cylinder 6 also fires, but the inlet valve will be shut, and that cylinder will be at the end of the exhaust stroke with only exhaust gas in cylinder six.

Waste spark is great for stock emission engines with standard cams. Even boosted engines. The Commodore supercharged 3. But if you fitted some decent cams to it, expect trouble. For competition it probably doesn't matter much. But for a road car, if you plan on running fairly weak mixtures for economy a longer plug burn time is likely to give less mis firing at very light throttle.

My choice would be coils and igniters for a road car, either one, three, or six. It all depends on the application. So six would cost about the same as a CDI. With traction control, it is ideal for circuit racing.

The Autronic SM2 includes harness, air and water temp sensor, internal map sensor, fuel pump relay, PC data cable, calibration and data logging software, page manual. Harness is flying lead type and has a connector which plugs into the Ecu, and socket for fuel pump relay.

Subaru WRX , and The original motherboard and connector are removed from the ECU case, and the Autronic motherboard and connector, clips or screws into the case. View More Photo Galleries.

Currently has loom attached that was on my MR2. Car ran a side feed intake manifold with edelbrock TB. Autronic IAT sensor was used and supplied, so is a bosch water temp sensor standard sensor they normally run with the autronic, will accept any water temp sensor though. Starter relay etc is encorporated into the loom, as per standard. Is designed to run the CAS sensor from dizzy plug attached. Temp sensor for the gauge cluster, electronic speedo sensor etc are wired through the loom to the body loom connectors.

This wiring and connectors for such are still intact on the loom, however it would be very simple to just wire a single ignition output to a single coil setup. Injectors were run through a weatherproof deutsch connector.
