Section 6: Introduction to the Keypad The keypad included with the system is the only way to see and alter the settings. There are three pairs of keys: The SELECT keys move through the main menu. When turning on the car, the ECU always wakes up in the RPM screen. This is considered the beginning of the main menu. Use the up and down keys to scroll through the menu choices. When it gets to the end of the main menu (where it says “EDIT Z0 XX”), it will stop. Once the desired screen has been found, changes are made to the setting by using the AD- JUST keys. Some screens don’t have any adjustable parameters in them, they are read only. The ADJUST keys are used to access additional information in some of these screens, for instance in the RPM screen, pressing the ADJUST down key accesses the current manifold pressure (MAP). The EDIT menu is a submenu of less often used parameters. It is accessed by holding the SELECT up key until it stops. At this point, the screen will display “EDIT Z0 XX”. You move through this menu by using the EDIT up and down keys. To make changes, use the ADJUST keys, just like in the main menu. Storing: When ever a change is made in the ECU it must be stored or the change will be lost when the car is turned off. There are two ways to store information. Storing will only occur at idle. First is in the STORE screen. In this screen press both ADJUST keys until the screen fills with asterisks, then release the ADJUST keys. The second way to store is in the EDIT Z menu. In any screen in the EDIT Z menu press both EDIT keys and the screen will fill with asterisks signaling that the new information is being saved. In both cases, the keys to initiate the save function can be released as soon as the asterisks appear. 14
Section 7: Setting Up the ECU for Your Car 1) Load Default values: The ECU contains 2 sets of default values to help speed along the tuning process. Turn the car “on” but do not start the engine. Scroll to the screen that displays RELOAD TABLE 1. Table 1 is for supercharged cars and Table 2 is for turbocharged cars. Press the adjust down key to switch to Table 2 for turbocharged cars. 2) Press the select up key once to go to the RELOAD screen. Here, press and hold both adjust keys until the screen fills with asterisks, then release the adjust keys. This loads the default settings into the ECU. 3) Check MAP SENSOR operation: In the RPM screen press the adjust down key on the keypad to display the MAP sensor reading. At sea level the MAP reading should be about 100kPa. Higher elevations will read lower values. The MAP sensor has an accuracy window of +/-5kPa. Refer to the table below for the atmospheric pressure at different elevations. Elevation (ftX1000) 0 1 2 3 4 5 6 7 8 9 Pressure (kPa) 100 97 94 91 87 84 80 77 74 71 4) Set ONSET: Go to the ONSET screen and set it to 100kPa using the adjust keys. This sets the piggyback to start making is fuel and timing changes at 0 on the boost gauge. Below ONSET the car operates completely on the stock ECU and fuel injectors. 5) Set the boost target: Go to the BOOST screen and set it to 100kPa. This will limit the boost to the value set by the mechanical wastegate controller on the turbo or the external waste gate. This will be about 6psi on an FM2 turbo kit. Setting the ECU up to raise the boost pressure will be covered in the next section. 6) Store these changes. 7) Start the car and check for fuel leaks around the junction of the auxiliary fuel injectors with the fuel rail. 8) Check the vacuum signal: Go to ONSET screen and check the number in parentheses. This measurement is the vacuum in the intake manifold at idle. The reading should be steady between 25kPa and 35kPa. If you do not have a reliable map signal, nothing in the ECU will work correctly. Note: The fuel numbers loaded into memory have been developed on our Dynojet chassis dynamometer with a wide band O2 sensor. These are more accurate than what can be obtained from the air/fuel meter supplied with the kit, using the stock O2 sensor in the car. These values have proven to work well for boost values up to 12psi. Therefore, we do not recommend changing them unless tuning is being performed with a wide band O2 sensor. 9) Test Drive: Go for a drive with the top and windows up. The boost will be set by the mechanical wastegate actuator on the turbo to around 6psi. Drive gently at first to make sure 15
