AWD vs FWD ECU's.

I'm about to put an ECU from an AWD California emissioned 91 Talon Turbo 5-Speed into my FWD non-California emissioned 91 Talon Turbo 5-Speed car. Does anyone at all see a problem with putting an AWD California emissioned ECU into a FWD non-California emissioned car? I'd appreciate it if somebody could alert me to any pitfalls.

Thanks
Jon
