    This video shows a step-by-step process of disabling the EGR system on a Renault Megane II using the Titanium program. It shows how to open the original firmware, find and deactivate the EGR parameter, save the modified file (_EGR_OFF) and then write it to the car's ECU, which helps to increase the reliability of the engine.

  • Chip Tuning VW Touran 1.9 105hp: Disabling EGR/DPF with WinOLS/Titanium4:35

    This video demonstrates the step-by-step process of chip tuning Volkswagen Touran 1.9 105 hp, covering opening the original firmware, modifying parameters such as disabling EGR or DPF, saving the modified file and writing it to the engine control unit, followed by checking the car's performance.

  • Chip Tuning Audi EDC16CP34: Disabling EGR/DPF and Increasing Power4:45

    This video presents a step-by-step guide to chip tuning the Audi EDC16CP34 ECU. It covers the entire process: opening the original firmware, finding and changing parameters (e.g. disabling EGR/DPF, adjusting fuel maps), saving the modified version and writing the new firmware to the car's control unit, ending with a performance test.

  • Chip Tuning Mercedes ML 280CDI (EDC16CP31): Disabling EGR/DPF and ECU Firmware4:51

    This video demonstrates the step-by-step process of chip tuning Mercedes ML 280CDI (EDC16CP31). It shows how to open the original firmware, change the parameters, for example, disable EGR or DPF, and adjust the fuel maps and limits. Next comes saving the modified file, writing it to the engine control unit using programs such as KESS or KTAG, and a final check of the car's performance.

  • How to Flash Opel Astra Z13DTH: Increasing Power and EGR OFF (WinOLS/Titanium)5:02

    This video presents a step-by-step guide to chip tuning an Opel Astra with a Z13DTH engine. It covers opening the original firmware, disabling the EGR system and adjusting the Stage 1 parameters to increase power and engine response. Then it demonstrates saving the modified firmware and writing it to the car's ECU, followed by checking its functionality and test driving.

  • BMW 320d Stage 1: Modification of Firmware with WinOLS and KESS/KTAG9:06

    This video is a step-by-step guide to chip tuning a BMW 320d on Stage 1. It shows how to prepare and modify the original firmware (increase fuel delivery, boost, torque limits) using programs like WinOLS or Titanium, then save and write the new firmware to the ECU via KESS, KTAG or MPPS, finishing the process with a test drive and checking the car's functionality.

  • Mercedes CRD3 Stage 1: Modification of Firmware with WinOLS and KESS/KTAG10:36

    This video presents a step-by-step guide on chip tuning a Mercedes with a CRD3 ECU on Stage 1. It covers preparing and modifying the original firmware (increasing fuel supply, boost, torque limits) using programs like WinOLS, then saving and writing the new firmware to the ECU via KESS, KTAG or similar tools, finishing the process with a test drive and checking the car's functionality.

  • Test

Requirements

  • Basic knowledge of internal combustion engines is helpful but not required
  • Windows PC or laptop
  • WinOLS or ECM Titanium software (demo or licensed)
  • ECU reading/writing tools (KESS, KTAG, or equivalent recommended)
  • No prior tuning experience is necessary — beginners are welcome

Description

Chip tuning is one of the most effective ways to optimize and repair modern vehicles. In this course, you will learn how to modify ECU firmware using WinOLS, ECM Titanium, and professional tools like KESS and KTAG. Whether you are a beginner or a professional, this training will guide you through real-world examples of ECU tuning and calibration.

We begin with the most practical topics — EGR and DPF OFF. These systems often cause problems when the valve gets stuck or the filter becomes clogged. You will learn how to safely disable them in ECU firmware, avoiding errors and ensuring reliable engine operation.

Next, we move to Stage 1 tuning, where you will increase engine power and torque while keeping reliability in mind. We will analyze and edit maps such as torque limitation, boost control, injection duration, SOI, and smoke limitation, giving you a clear understanding of how each calibration impacts performance and fuel consumption.

What makes this course unique is the practical approach with real car projects. We will tune ECU files from Renault Megane, VW Touran, Audi EDC16, Mercedes ML EDC16, Opel Astra Z13DTH, BMW 320d, and Mercedes CRD3. You will see exactly how to read, modify, and write ECU firmware step by step.

By the end of this course, you will have the knowledge and skills to confidently perform EGR/DPF OFF operations and Stage 1 tuning on different cars, opening the door to professional ECU remapping services or personal tuning projects.

This course contains the use of artificial intelligence.

Who this course is for:

  • This course is designed for auto electricians, ECU tuners, mechanics, and car enthusiasts who want to learn practical chip tuning and ECU modification. Beginners will gain step-by-step guidance on how to disable EGR and DPF systems, as well as perform Stage 1 power tuning on real vehicles.
  • It is also highly beneficial for workshop owners who want to add chip tuning services to their business, or for technicians looking to improve their skills in WinOLS and ECM Titanium. Advanced learners will find value in the practical case studies on Bosch EDC16 and CRD3 control units, as well as hands-on demonstrations with KESS and KTAG tools.
  • By the end of the course, students will be able to confidently edit ECU maps, optimize engine performance, and apply reliable tuning solutions across a wide range of cars.
