Short Method from LS1 forum
Fast idle relearn [Archive] - Australian LS1 and Holden Forums
Short method after reset:
turn on the reds, don't start.
push the gas pedal down 3-5 times.
turn off reds
start car
-----------------------
My car is a stock standard 04 CV8 and I have tried the short method and it worked fine for me.
My car was idling high, around 1000/1100 rpm then after doing the relearn it has gone down to 800 (on the cluster not measuring with any plug in stuff).
Still goes a bit high when i first put the clutch in but, up say 50 to 150 rpm but aparently thats normal.
