Description

The ACES FUEL INJECTION Killshot 2 Pro EFI System is a 4-barrel throttle body injection (TBI) system with an external ECU designed for classic small/big block engines. It supports up to 650 HP (naturally aspirated) or 550 HP (boosted). Key features include a low profile, built-in fuel pressure sensor, progressive linkage, a B60 Chip, and expanded VE and spark tables (31x31). It also offers boost control (via firmware update), fuel level input, and additional I/O wires. The system is self-learning for stock-to-mild builds and can be fine-tuned with advanced software. It is E85 compatible (with tuning) and supports wet nitrous control (non-progressive).
