FiTech 38350 Ultimate SBC TPI Standalone EFI System
There were thousands of small-block Chevy engines fueled by the OEM Tuned Port Injection (TPI) systems back the mid ‘80s to early ‘90s. These were popular engine swaps years ago, but the electronics and tuning capabilities left a lot to be desired.
To help bring your GM TPI system up to date, FiTech now offers a Retro-Fit EFI system. The kit is based on their proven, self-learning EFI technology and will improve the performance and driveability of your TPI equipped small-block and give you more custom settings for your application and even the lock-up of the 700-R4 or 200-4R converter.
An efficient yet compact ECU is easy to mount and connects through a new wiring harness that is terminated with factory style connectors for the TPS, IAC, CTS, Knock Sensors, injectors and distributor. A new Wide-Band 02 sensor is supplied to constantly monitor the air/fuel mixture plus the harness plugs into the factory distributor, injectors and sensors then can easily be calibrated to your specifications through the color touchscreen handheld controller
- The computer is compact for discrete mounting in various locations
- OEM-style terminated wiring harness connectors for plug-and-play connection of Throttle Position (TPS), Intake Air (IAC), Coolant Temperature (CTS), knock sensor, injectors, and distributor
- Setup and monitor air/fuel parameters through the color touchscreen hand-held controller
- 3-Bar Manifold Absolute Pressure (MAP) sensor supports up to 25 psi of boost - No mass airflow (MAF) required
