Certainly! If you’re looking to program the Continental SIM2K-241 engine control unit (ECU) in your 2011 Hyundai Elantra, here’s what you need to know:
Unlocking the ECU in Bootloader Mode:
Before programming, you’ll need to unlock the ECU in Bootloader mode. This step allows you to perform connections in OBD Full and Bench modes without reopening the ECU each time1.
Once unlocked, you can proceed with the programming process.
