I was given a PCM by a friend who had no use for it, figured I'd check here to see if it's any use in LS land.

Numbers on the PCM are:

Serv. No. 12209614 YCWZ
*86YCWZM12249GJ7K* 12579925
HDW. NO. 12202600

A quick google search shows that it's a PCM for an '03 Malibu. Can it be re-flashed into anything useful?

 

no, Just a Malibu, it is missing lots of stuff inside to make it work on anything else. ebay maybe 30 bucks.. My core cost is 4.
