I took my Camary in for some work and they told me that the computer needed an upgrade. Is this true or are they just trying to get more money?

There is a Technical Service Bulletin for ECU reflash. As far as I can tell, they do that so they don't have to remove the ECU every time they need to work on the vehicle.

Flash reprogramming allows the ECU software to be updated for changes in vehicle calibrations without removing the ECU from the vehicle. Flash calibration updates for specific vehicle models/ECUs will be released as field fix procedures described in individual service bulletins. This bulletin details the ECU flash reprogramming process and the applications within the Technical Information System (TIS) and the Toyota Diagnostic Tester used for reprogramming.[/quote:7648fcda87]
If you never had any problem with the vehicle, I don't see spending $100 for the re-flash.
