The HYPERTECH 85 Corvette 350 TPI Auto Computer Chip is a direct bolt-in engine control module replacement designed specifically for 1985 Corvette models equipped with the 350 cubic inch TPI (Tuned Port Injection) engine and automatic transmission. This chip is ideal for Corvette enthusiasts and restoration professionals looking to optimize their vehicle's performance.
This OEM-grade chip recalibrates the factory ECU parameters to improve drivability across the RPM range while respecting the stock transmission's torque limits. It modifies fuel delivery curves and spark advance tables to better accommodate modern fuel blends, aiming to enhance overall engine performance without requiring complex wiring modifications or secondary tuning equipment.
C4 Corvette owners performing fuel system diagnostics, stock restoration, or mild performance upgrades will benefit from this plug-and-play chip. Installation is straightforward, requiring basic mechanical knowledge to disconnect the negative battery terminal, swap the chip, and retest fuel pressure and idle stability.
