I've been contacted to sort out a Turbo Regal/Grand National (It appears to be a GN conversion), and so far everything points to an ECM problem. He's already bought two that are not the correct ECM, and so I'd like to find at least one if not two 1227148 ECMs. I know these wre used in Turbo Regal/Grand National and a couple other SFI Buick V6 applications, FWD if I'm not mistaken.

Let me know what you have.
