Where to get an ECM & Eprom

Hello,
I am looking for an ECM and an Eprom package (the blue cal-pack/chip) for a 1991 ZR-1. Any idea ?
Thx
Steve

Looking for both or just the cal-pak?

If u mean any LT-5 ECM, yes. As long as u use the correct year calibration.

I believe any year ZR-1 ecm will work as long as you have a crrect year eprom - cannot use an ECM out of a LT1 car.

I am looking for both, the ECM and the cal-pack.
As I understood from some replies any LT5 year ECM will do but the Cal-pack will need to be a 1991 ...

To be accurate, any calpak will work as long as the correct model year calibration is burned on it. The one exception for this is the 90 calpak which does not have the knock filter on board.

Not unless its a LT5 ECM. With the correct MY Prom for the LT5
