TL;DR Proteus Manual

Goals and Non-Goals

Goals

• Run my LS-swapped Volvo 240 with factory harness and equipment
• Run a sequential ignition, quad-VVT v12 engine (twelve injectors, twelve ignition, five hall sensors, four VVT actuators, dual throttles)
• Easily manufactured sealed enclosure (all connectors mount in-plane)
• Extensible for knock sensing properly implemented onboard knock sensing!

Non-goals

• Internal logging (doesn't make sense with 12 mbit/s USB, and a sealed enclosure) Version 0.4 has an SD card!
• Direct injection
• Cheap
