you will need an ecu that matches the engine. there may be others that will work, but only the model ecu that is suppose to go with the engine is tuned for that model engine

the engine is 2000 so if i got one would i have to recode it for my car? for my immobilizer n what not?

[quikflip27]

whats your definition of recode? what year is your car? if youre talking about the immobilizer on your alarm, dont worry about all that stuff, its all under your dash, wired into the inside harness, not the engine.
