By shifting the slider towards the positive sing the gas extra injections time increases and the mixture becomes richer By not enabling the tick the extra injection is not considered as such and the gas control unit manages the impulse as a normal fuel injection ENRICHMENT IN ACCELERATION In some car models by accelerating suddenly the PETROL injection time shifts quite simulta neously from a medium low value to a high value e g 15 16 ms This during the use by GAS can cause malfunctions since the carburetion would be greatly enriched To avoid this problem use the slider Enrichment during acceleration as follows By shifting it towards the positive sing the control unit will follow the changes in the PETROL injection time always quicker By shifting it towards the negative sing this change will be more and more limited and filte red LEANING ON MAZDA On some MAZDA models during the petrol feeding during acceleration a switching occurs from a SEQUENTIAL type injection mode to a half group injection mode with opening by pairs of the petrol injectors This condition can be easily recognized observing during the acceleration the movement of the RED point on the map or the PETROL injection time During the switching from one injection mode to the other it is possible to observe that the injec tion time usually displayed acquires a value equal to about the half of the one previously carried out for exa
