This block will allow the tuner to choose different options to set up timing for this engine. Each of these methods will be discussed in detail under the tuning chapter further in the manual. You can see the Tuning section for detailed description on the tuning side.

Graph MAP
This is for standard engines with a good vacuum signal and allow for easy tuning in the street.

Graph MAP+TPS
This method is used for engines with a poor vacuum signal at low RPM’s and it still allows for easy tuning in the street. The ECU will use the TPS signal to calculate a MAP signal at low RPM’s when there is no or little vacuum. It is used for engines where the vacuum signal is correct and above 1500RPM’s. The graphs are the same as above with the addition of the following settings:

When the RPM’s are below the RPM fuel cut off, then TPS idle is activated. The Vacuum Fuel Cut off setting then becomes the minimum manifold pressure value to start off from.

The TPS gain value will use the TPS signal to calculate a projected vacuum signal on the graph. When the actual vacuum is below the calculated vacuum then the ECU will use the lowest vacuum signal of the 2. Once RPM’s is above the RPM fuel cut off, then TPS idle is de-activated.

Matrix MAP

This is for standard engines with a good vacuum signal and allows for easy dyno tuning. Here the MAP sensor versus RPM is used and the blocks are set in 0.1 milliseconds resolution.

Matrix TPS

This is for normal aspirated engines with poor vacuum signal or throttle bodies and allows for easy dyno tuning. Note: It is recommended to add the altitude sensor to compensate for altitude pressure changes. TPS versus RPM does not compensate for pressure changes. Here the TPS sensor versus RPM is used and the blocks are set in 0.1 milliseconds resolution.

Graph MAP + Matrix TPS

The Matrix is the same as TPS Matrix above. This is for turbo racing engines with a good or poor vacuum signal and allows for easy dyno tuning. Note: It is recommended to add the altitude sensor to compensate for altitude pressure changes in the TPS matrix. Here the normal aspirated tuning is done on the matrix and the boost tuning is done on one Fuel Load graph. It will become visible in this mode. Here the TPS sensor versus RPM is used on the matrix and the blocks are set in 0.1 milliseconds resolution. Then Map sensor is used to modify fuel under boost. Notice how there is no fuel if there is no boost. This fuel is calculated as % boost compensation.
