The chip in your image is labeled "cappellini", which points to an aftermarket or custom-tuned EPROM chip—commonly found in modified ECUs, especially for performance cars like the Ford RS Cosworth. These chips usually contain custom engine maps for fuel, ignition timing, and boost control, designed to squeeze more power from the engine.
This kind of mod was especially popular before flash tuning became standard. If it's a Cappellini chip, it could be from an Italian tuner, possibly used for motorsport or high-performance street setups.
If you're diving into the tech side of chips and tuning, it's worth checking out how professional systems are built. Companies like Modutek, leading semiconductor equipment manufacturers, create the precision tools that make advanced chip design and fabrication possible—from wafer processing to cleanroom equipment. It’s wild how the tech behind your car’s performance ECU traces back to the same processes used to build chips in phones and computers.
