Indian application) to maintain desired idle speed. (set SA idle =0 at SA idle Tab

at 90 deg C, then recovery the Injflow to the original setting).

• Convert the voltage to MAP: Formula depend on the MAP sensor’s specification.

MAP=Voltage*18.875+10.341

将MAP传感器的输出电压转换为MAP读数。计算公式取决于MAP传感器的规格。( MAP=Voltage*18.875+10.341)Minimum MAP value in 1 cycle is MAP at IVC( intake valve close)

一个循环中MAP的最小值出现在进气门关闭时。

Convert the MAP data range from 15~85 to 30~100.

5. VE Table Calibration(Chassis dyno or Engine dyno. Chassis dyno

is close to realities)

point and adjust VE table value so that the exhaust A/F is 14.6.

在开始VE标定之前将空燃比设定为14.6。在每个节点上调节VE值使测量得到的空燃比为14.6。

A/F to maintain the exhaust gas temperature less than 875degC and record the

exhaust A/F

maybe use 15.3.
