Bought Used LS400 ECM (1994)--- Do i need it programmed/flashed?
i think i read that OBD1 ECMS don't need programming or to be flashed, is this the case? or would it be plug and play? thanks

My advice: after you plug it in, turn the key to battery and let the power cycle through it and let the ecm do its system checks. After it calibrates (about 30-60 seconds) then crank it up.

Sure. I say plug it up and play cause you never really know with used ecm. Also check the alarm module like dicer said.
