Detailed Curriculum

Key Training Modules

ECU Pinouts & Connections

Learn to locate correct boot/OBD2 pinouts and safely connect Denso & Keihin ECUs to programmers using CAN-Bus, K-Line, and GPT lines on benches.

ECU Flashing & EEPROM

Master safe reading, writing, and backup procedures for Flash and EEPROM memory chips using specialized tools like KTAG, KESS, or PCMTuner.

Map Editing & Tuning

Identify and modify critical engine maps (fuel injection, ignition timing, and boost limits) inside binary dumps using professional hex editors.

Immobilizer Bypass (Immo-Off)

Understand anti-theft loops, locate security security bytes inside EEPROM files, and perform Immobilizer bypass (Immo-off) for engine swaps.

DTC Removal & Fault Off

Identify specific diagnostic trouble codes (DTCs) in binary hex dumps and learn how to permanently disable them (DTC Off) for custom setups.

Bench Simulation & Testing

Wire up ECUs on test benches and simulate vehicle engine signals to verify that software flashing and map modifications are 100% stable.
