I started to wire the layout around 15 years ago and was always very diligent in following the prescribed methods.
What is interesting is the impact Rev L has on PS3 engines. The entire layout (4 loops, 4 channels) is now seeing near perfect signals with PS3. This was previously only seen with PS2. This also explains some of the temperamental behavior I would experience with PS3.
This is an important lesson that bears repeating, as I learned it here🙂
