The injector driver is in the ECU, not the e manage. U can change the injection pulse via injector harness(ECL illumintate), but cannot change the current output of the coil driver like always said... U need a resistor pack. Why do you need to ask 100 times.
390cc/450cc/510cc from older gen Mitsu are all low impedance injectors. And GTI ecu is driving high impedance injectors. Thus, there's only 2 possibility if u insist on "emanage can control injector current" idea.
1) If you're lucky - The injector went gila and whatever Air flow correction u key in doesn't show any effect.
2) If you're unlucky - U fry your ECU. That's all.
A resistor pack is only RM50-RM80. If you know how to DIY, It's <RM20. Why do you want to risk you ECU just to safe the RM20-RM80.
Nuff said. Read the below if you have time.

Yeah, u mentioned the word "CURRENT SETTING". Thanks.
