39 Point by point calibration instruction Correct Map Point by point calibration instruction Correct Map - FEEDBACK System SECOND PHASE OF MAPPING - Again with the engine in neutral gear, accelerate brusquely. If the engine speed (RPM) does not increase uniformly, select cells as shown in the figure. Press ENTER/RETURN; in the Modify Map Values window, use the Percentage option to modify the values by making small corrections, positive if the mixture is lean and negative if the mixture is rich. FEEDBACK MAPPING (for automobiles for which there exists no specific OBD emulator; e.g., Citroen and Peugeot) - Emulation with the FEEDBACK system is performed as outlined below. - Once system installation is completed (with the automobile in the gasoline operation mode), the next step is to acquire about 40 points distributed over the entire map. To acquire a point, simply position the dot on the cell; as soon as the lambda probe begins to oscillate between red and green, press SPACE to acquire the value. Once point acquisition is completed, click Download Road-Acquired Map. In the gasoline fuel mode, proceed at a steady speed to various points on the map and check that the gasoline correction value (on the lower right of the display) remains within a maximum value range of +/- 00. If so, the map is good; contrariwise, any chosen point may be precisely corrected, taking the gasoline correction value as the point value. Example: if at a given point on the map we see a gasoline correction value of 350, use the mouse to light the correction window and enter a value of -35%. When gasoline mapping is completed, it is possible to go on to GAS mapping by setting Lambda emulation on the FEEDBACK screen. Pag Pag

This value affects driving quality (smoothness) (We recommend not changing the preset value, at least initially). Enter the CUT-OFF stop delay time, in seconds. This value affects driving quality (smoothness) and idling stability (We recommend selecting values in the 0.04 to 0.48 range). If the engine stalls upon return to idle speed, use only lean mixture or no CUT-OFF. SECOND PHASE OF MAPPING - Again with the engine idling, modify the cells adjacent to the red reference point in such a manner as to obtain more similar values. This modification will result in greater engine stability at idling speed. In this phase, work in such a manner as to bring the correction close to zero, with a temperature of about For example: maintain a time interval of between 0.4 and 0.8 between one line of the map and the next. Between one RPM line and the next in the interval between 500 and 500 RPM, up to a MAP value of.08, maintain a time interval between 0. and 0.. Pag Pag
