kalau mau mentahan apk app invertor jangan lupa sawer dulu ya :D, masukan email pada note saweria https://saweria.co/vprojectmakers

note:
untuk pemasangan relay kejalur coil:
*LEPAS KABEL SIGNAL COIL (NEGATIF COIL, BIASANYA ADA WARNA HIJAU PADA SKUN COIL)
*COM RELAY KE KABEL SIGNAL COIL YG DILEPAS
*NC RELAY KE PIN SIGNAL / NEGATIF PADA COIL (BIASANYA ADA WARNA HIJAU PADA SKUN COIL)
