99 ECM Replacement Options?

[DonS47]

My 1999 Avalon ECM needs to be replaced. The local Toyota dealer, with help from Toyota Tech Support determined my P0505 code (Idle Air Control Valve) was due to a bad ECM. (I'd already replaced the IACV.) A new ECM is $1000 plus $500 for installation and programming. I've seen used ECMs on E-Bay for $100. My car is California compliant. If I buy a used 1999 California-compliant Avalon ECM, should I be able to just swap it out? If not, can a Toyota Dealer reprogram it for me?

yes, you should be able to just swap in an ecu from an identical car

the reprogramming stuff quoted from the dealership is BS

FYI, ECU covered by 8 yr/80K mile warranty.
