Hi there,
In most (if not all) JDM Canbus (08+) ROMs, closed loop takes a while to activate. The AF Sensor stays "off", resistance is "255", so the ECU doesn't trigger the Sensor heating at all before some time.
This topic also explains the behavior:
viewtopic.php?f=15&t=17400I believe there must be a decay table of some kind, thus forcing Open Loop operating when the ECT is low.
Did anyone ever find those tables? I'd like to apply the same behavior on some other non-JDM roms, which would help with the warm-up routine.
Best regards
