Diesel Engine Remapping Course

Lesson 1 • Engine Architecture and Components

Examines block, head, pistons, injectors, and valvetrain. Understanding component roles is essential before modifying any engine parameter.

Lesson 2 • Turbocharging and Air Management

Covers turbocharger operation, intercooling, and boost control. Boost management is a primary lever in diesel remapping.

Lesson 3 • Fuel Delivery and Injection Systems

Explains common-rail, unit injector, and pump-line-nozzle systems. Injection system type directly determines which ECU parameters are tunable.

Lesson 4 • Diesel Combustion Principles

Covers compression-ignition theory, air-fuel ratios, and combustion phases. Establishes the thermodynamic foundation needed for all subsequent tuning decisions.

Lesson 1 • ECU Software and Firmware Structure

Explains bootloaders, operating software, and calibration layers. Distinguishing firmware from calibration data prevents irreversible ECU damage.

Lesson 2 • ECU Communication Protocols

Introduces OBD, CAN bus, K-line, and proprietary protocols. Protocol knowledge determines which interface tools and methods apply to each ECU.

Lesson 3 • ECU Security and Protection Mechanisms

Covers immobilizer integration, seed-key algorithms, and read protection. Understanding security layers is required before attempting any ECU access.

Lesson 4 • ECU Hardware Overview

Examines microcontrollers, memory types, and communication interfaces inside an ECU. Hardware knowledge guides safe read and write procedures.

Lesson 1 • Data Logging and Parameter Monitoring

Teaches real-time logging of boost, fuelling, and temperature channels. Quality log data is the evidence base for every calibration decision.

Lesson 2 • Dynamometer Testing Fundamentals

Introduces chassis and engine dyno operation, load control, and result interpretation. Dyno testing provides controlled, repeatable performance measurement.

Lesson 3 • ECU Reading Methods and Interfaces

Explains OBD-port reading, bench reading, and direct chip access. Method selection depends on ECU type, security level, and available hardware.

Lesson 4 • OBD and Diagnostic Scanner Use

Covers scanner connection, fault code reading, and live data streaming. Diagnostic scanning is the first step before any calibration change.

Lesson 1 • Checksum Correction Procedures

Explains checksum algorithms and correction tools for common ECU families. Incorrect checksums cause ECU rejection of the modified file.

Lesson 2 • Writing and Flashing Modified Files

Covers full flash, partial flash, and recovery procedures for failed writes. Safe flashing technique prevents ECU corruption during calibration upload.

Lesson 3 • Remapping Software Interface Navigation

Covers workspace layout, file import, and view modes in tuning software. Efficient navigation reduces errors and speeds up the calibration workflow.

Lesson 4 • Map Identification and Comparison

Teaches auto-detection, manual map searching, and file comparison tools. Accurate map identification is prerequisite to any safe editing.

Lesson 1 • Boost Pressure and Turbo Control Maps

Covers boost target maps, wastegate duty, and VGT vane position maps. Boost calibration must be coordinated with fuelling to avoid over-fuelling.

Lesson 2 • Rail Pressure Control Maps

Examines rail pressure target maps and pressure regulation strategies. Rail pressure affects atomisation quality and injection duration accuracy.

Lesson 3 • Injection Quantity and Fuelling Maps

Covers main injection quantity maps, torque limiters, and smoke limiters. Fuelling maps are the primary determinant of power and torque output.

Lesson 4 • Injection Timing and Advance Maps

Explains start-of-injection timing, pilot timing, and advance correction maps. Timing directly affects combustion efficiency, noise, and emissions.

Lesson 1 • Stage 1 Remapping Methodology

Teaches conservative fuelling and boost increases within stock hardware limits. Stage 1 tunes maximise output without requiring hardware modifications.

Lesson 2 • Iterative Testing and Refinement

Covers test-log-adjust cycles, knock and smoke monitoring, and final sign-off. Iterative refinement ensures the calibration is safe and meets targets.

Lesson 3 • Stage 2 and Hardware-Supported Tuning

Covers calibration changes that accompany upgraded intercoolers, injectors, or turbos. Hardware upgrades shift the limits that calibration must respect.

Lesson 4 • Establishing a Baseline Calibration

Covers stock file analysis, baseline dyno runs, and target setting. A documented baseline is the reference point for all subsequent changes.

Lesson 1 • Selective Catalytic Reduction Systems

Explains SCR operation, urea dosing, and NOx conversion efficiency. SCR calibration affects emissions compliance and system fault generation.

Lesson 2 • Emissions Testing and Measurement

Covers exhaust gas analysers, opacity meters, and emissions test procedures. Measurement skills allow calibrators to quantify the emissions impact of changes.

Lesson 3 • EGR System Calibration and Emissions Impact

Examines EGR's role in NOx reduction and its trade-off with soot production. Calibrators must understand these trade-offs to make responsible tuning decisions.

Lesson 4 • Regulatory Awareness and Responsible Tuning

Addresses emissions regulations, type-approval concepts, and professional responsibility. Calibrators must understand the regulatory context in which they operate.

Lesson 1 • Multi-Injection Strategy Optimisation

Explains pilot, main, and post injection quantity and timing interaction. Optimising multi-injection strategies reduces noise, emissions, and fuel consumption.

Lesson 2 • Fault Code Analysis in Tuned Engines

Covers fault codes generated by calibration changes and distinguishes them from hardware faults. Accurate fault analysis prevents unnecessary component replacement.

Lesson 3 • Drivability Problem Diagnosis

Addresses hesitation, surge, smoke, and rough idle caused by calibration errors. Systematic drivability diagnosis links symptoms to specific map regions.

Lesson 4 • Platform-Specific Calibration Challenges

Addresses unique constraints of high-mileage, agricultural, and marine diesel platforms. Adapting strategies to platform context is the mark of an advanced calibrator.
