IT is piggy back ecu, it has 16X16 mapping = 256map.
or it call sub-computer in which the airflow sensor signal or the pressure
sensor signal can be mapping to fine tuning the car each map to in order to to increase/decrease fuel for each engine revolution.
Even in light tuning such as an air cleaner/muffler replacement, a shift in air/fuel ratio occurs in greater or lesser degrees. This is due to the difference between the airflow detected by the airflow sensor and the actual airflow caused by a change in the airflow that passes through the airflow sensor.
The e-manage can correct this difference to set the original air/fuel ratio and increase the power. It also has various functions such as a VTEC control function and a function to prevent engine stall.
Furthermore, it can be used as a meter to check vehicle conditions with various monitoring functions. But need to buy the Greddy Profec E-01 to check vehicle conditions.
it is something like afc neo also but have more map than the afc neo.
AFC neo 16X2 map
E-manage 16X16 map
F con is which have 16X24map
remember the more the mapping in the aftermarket ecu the more precise u can tune your car.
But if your car are under 400HP not recommended standalone is not worth the investment.
RM950 for blue e-manage with out harness
Rm2100+- for ultimate e-manage with out harness
so clear yet, hope u understand.
Happy modding dude!!
