Legacy ECU Flash prior to 1998 Model Year
Enhanced DRB III Emulator supports ECU Flash for non-CAN Chrysler Group vehicles for 1998 and newer model years. ECU Flash on 1997 and prior model years requires a physical DRB III device. If a user attempts to download a 1997 model year or prior ECU flash file for use with Enhanced DRB III Emulator with TechTOOLs, TechTOOLs will give an error stating: DRB III Emulator does not support model years prior to 1998.
ECU Flash on 1997 and prior model years requires a physical DRB III device. If you do not have a physical DRB III device, you can rent one from Controller Technologies Corporation. Please see their website for additional details: https://www.controllertech.com/products/drb-iii-rental
