Blown ECM

hey guys..!!

i drive a chevy aveo 1.4.
im running an FFE and a filter.

off late my car started stalling everytime i put on the ac or redlined it..
got everything checked and scanned a zillion times nothing showed..
finally i got an ecm from another aveo and the car was fine..!

ok few questions..
can the aveo/optra ecm be repaired?
can the aveo 1.4 run on an aveo 1.6 ecm?..all the internals are the same.from what ive got from an international forum the 1.6 is a stroked 1.4.

ok guys Help!!!
i need to do it asap…as in today itself!!
