Today I will teach you how to chip your MK3 Volkswagen. This process involves removing and installing the ECM of the car, as well as replacing the “chip”. This is also known as tuning the vehicle. We are going to be performing this VW DIY on my MK3 GTI with the VR6 engine. Not only does this ECM tune provide about 10HP increase, it deletes several emissions components.
Join me today as we learn:
- Tools needed for chipping a MK3
- Removing a MK3 ECM
- Disassembling a MK3 ECM
- Removing and installing the ECM chip
