89 Iroc 5.7 TPI ECM interchangable w/ 89 Vette 5.7 TPI? - Third Generation F-Body Message Boards

Will an 89 Iroc 5.7 TPI ECM fit an 89 Corvette 5.7 TPI? Reason I am asking is because my dad is having problems with his Vette. We think it may be the ECM and I have an extra one from my 89 IROC. Any help would be greatly appreciated.

The '86-'89 Y and F body cars used the same ECM. Note that the MEMCAL will be different between them. See the sticky's above if not sure what the MEMCAL is.
