FiTech 38351 Details

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 drivability 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. New dual Wide-Band 02 sensors are 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
