Embodiment 1
[0032] Such as figure 1 As shown, the method for optimizing the performance parameters of the electronically controlled fuel engine by using an external ECU includes the following steps:
[0033] (1) Install and set up an external ECU between the sensor of the original car and the ECU of the original car;
[0034] The installation and setting steps of the external ECU in step (1) are as follows:
[0035] (11) The external ECU is connected between the sensor of the original car and the ECU of the original car through serial connection;
[0036] (12) Enter the parameter table MAP in the plug-in ECU;
[0037] (13) Enter the logical look-up function F() that matches the parameter table MAP in step (12) into the external ECU.
[0038] (2) Adjust and calculate the input signal of the original vehicle sensor through the external ECU;
[0039] The signal adjustment and calculation formula of the external ECU in step (2) is:
[0040] s' mn =F(s mn ,MAP(m,n,D)),
[0041] Among t...
