	Thanks for every comment.
		Yes,S4 is very sensitive to climate,it love cold.
	Thailand is a few latitude above equator.
		Yesterday,after I take out the Motronic box and see
	whether those high-hp. chips are still there,yes they are.
	And I replace Motronic box in place (It's really difficult.!!
	,I alomost can't connect the big connector back to the box)
	.Today I drive it to dealer. I wonder ,everything is perfect
	again,it's accelerate well. However I still let the mechanic 
	to drive it,he siad it's OK.	Mechanic said may be contacts
	on Motronic box is dirty (like in batterry terminal) ,when I
	disconnect it and reconnect it,it like cleaning all the pins.
		He said I have to take it out again (Geez...I'm sick
	of repeat all the procedures..1!) and use contact cleaner to 
	spray all pins.
		On Monday I'll clock 0-62 again ,hope this time it's
	around 7.x
