Disconnected the AFM socket ==> It simply because Bill has shown it to me when he was in KL. You were there also lah... but keep tok kok around and never pay attention. Theory behind? ECU running in limp mode when one of the sensor's signal is absent (may be...)


Disconnected the ISCV ==> without any voltage applying to the ISCV, its opening is 50%. This is more than enough for the engine to idle.


I disconnected the ISCV because i don't want the ECU to interrupt the idling rpm when i measure the airflow of the individual throttle. Imagine if you let the ISCV connected and when half way tuning the throttle bypass screw, suddenly the ECU gatal go change the ISCV's duty cycle, then airflow also change.... die lor have to redo all again.
