Holley Self Learning Efi Computer

Much like how our phones have more computing power than the first manned space flight had onboard, comparing today’s fuel injection computers to the ones from 20 years ago is kinda funny as well. This computer is from a Holley self-learning HP EFI TBI system. It is half the size of the other computers, has vibration-reducing feet, and no heat sinks. This shot from the end shows how it is fully potted, and under that blue cap is a mini USB programming plug. The arrow shows the tiny little vent. While I wouldn’t hesitate to dunk this computer, I’d mount it with the vent pointing down. If repeated dunkings are in the future, you might want to mount it inside a Tupperware food container.
