TPI Vats Module

The Painless Wiring TPI VATS Module (part number 64023) is an electronic control unit designed to facilitate the integration of vehicle anti-theft systems with modern engine management platforms. It is particularly useful for vintage TPI (Tuned Port Injection) engine swaps and restorations, allowing compatibility between factory security systems and aftermarket wiring harnesses.

This compact module acts as a relay bridge between the vehicle's factory VATS security circuit and the TPI fuel injection system. It decodes the resistor-pellet security key signal and translates it into parameters the TPI ECU recognizes, helping to prevent no-start conditions that can occur during modified fuel-injected conversions.

Ideal for those converting carbureted or older fuel-injected engines to TPI systems, this module is compatible with classic Chevrolets, Camaros, and Firebirds equipped with VATS security. Its installation is straightforward, requiring minimal wiring modifications to the existing harness configuration.
