TuneBoy Tune Editor

Return to Features

The default mode for TuneBoy Tune Editor only shows two tables, these are the fuel trim table and ignition trim table. This is done so that the first time user can get up to speed without being overwhelmed by all the things that can be changed.

The following is a list of some of the tables the TuneBoy Tune Editor program can change.

Fuel Map

The main fuel map is made up of a grid divided into 16 throttle points and 24 RPM points. With TuneBoy Tune Editor you can change any part of this map, this allows very fine control over the fuel system and allows any changes to be catered for.

The Aprilia tunes have a map for each cylinder as the demands of the front and rear cylinders are very different.

The fuel map can also be shown as a 3D Graph to make it easier to see areas that need work.

Ignition Map

The ignition map is made up of a grid divided into 16 load points and 16 RPM points. The values in the map are degree's before top dead centre where the spark plugs are ignited.

Fuel Trim Map

The Fuel Trim Map provides a way to adjust the Fuel Map by a percentage, the Fuel Trim Map has a location corresponding to each location in the Fuel Map, the percentage adjustment for each trim map location is applied to the Fuel Map when you download the map to the bike. This is a similar method of adjustment as the PCIII.

Ignition Trim Map

The Ignition Trim Map provides a way to offset the Ignition Map by a number of degree's, the Ignition Trim Map has a location corresponding to each location in the Ignition Map, the degree's adjustment for each trim map location is applied to the Ignition Map when you download the map to the bike.

A/F Map

The Air Fuel Target maps (A/F 1 and A/F 2) are used by the ECU to calculate the ratio to mix the air and fuel at, this provides us with a way to adjust the bikes mapping without needing a dyno.

3D Graphing

The TuneEdit program can display the data in table format or as a 3D surface graph.
