Re: ECU Replacement

If you buy a reman or new ECM it will need to be "flashed" with the programming needed for your VIN#.I would imagine you want the year of your chassis/VIN and not the engine year.
(94-up Cavalier/Sunfire ECMs have no PROM chips,the programming is stored in FLASH memory.This way the same ECM can be used for different applications,they just change the programming.Also,any recalls or updated programming can be done with no ECM removal,just a plug in reprogramming operation.)
