Engine Main

Engine Type

This entry designates the engine type. There are 2 type of engine which the Emtron ECU’s can control :

4 Stroke - This the most common engine type. An engine cycle lasts two engine revolutions.

2 Stroke - Less common engine type. An Engine cycle lasts one engine revolution.

Engine Size

The engine capacity in total cc. It is critical that this settings is accurate.

The capacity entered here is used for various ECU calculations in creating the engine model.

Tuning Tip

Any increases to the accuracy of the information entered into the configuration of the ECU, will serves to reduce the level of calibration error.

The importance of this cannot be overstated if the project is to be torque modeled. What this means is you should spend the extra time to ensure all entries are facts. Example: If the engine capacity is said to be a 6.2litres, but the actual capacity is 6162cc, it is important that the correct actual capacity is entered. Any error minimization in the configuration stage will serve to minimize the included calibration error in the tuning stage after. This is true for all configuration entries an not isolated to engine capacity. In short, if you put the effort into the configuration, your job will be easier when it comes to tuning.

Compression Ratio

This value is the static compression ratio of the engine. ie: Swept volume over clearance volume.

NOTE: This input effects the Torque Model as well as the Fuel Model: Expansion Ratio calculation.
