Yap, may ECU yung hi-ace jap ver. Mayron nga ata pressure check switch yung AC system. So pag mataas yung RPM eh tumataas din yung pressure sa AC system? Parang protection ba ito sa compressor? Naalala ko kasi noon may luma kaming toyota 3K yung engine kahit anong apak sa gas o kahit nakarecta eh hindi naman nawawala yung lamig ng AC siguro dahil wala siyan pressure switch?[/SIZE]
