I'm not saying that explorer is better. but has features that should appear in AH4 (software downgrade to the first level in F / G series, programming cas4 / 4 + via obdII, write calibration F and G series, reading ISN (SK) DME83T1, DME84T1 (MDG1) B38C, B48C via OBDII, AIF / UIF modification in the E series. Then AH4 will be the most powerful tool
