Our harness upgrades the 1985 through 1989 TPI engines by running them on the 1990-92 Camaro or Firebird computer. Using the 1985-89 engine, the computer, prom, and knock sensor will have to be changed to 1990-92 components. This system uses a M. Sensor for fuel calibration instead of a mass air flow sensor. You benefit from an easier installation by not having to install the mass air flow sensor which is encased in a big, hard to route, air intake tube. All necessary computer controlled sensors are utilized as in the original vehicle. The transmission types available were 700R4, 4L60 and the manual transmissions behind the engine. You can also use the turbo 350 and 400 transmissions. The ECM requires a four thousand pulse per mile speed input. We have been in business over 30 years! EXCEPT on international orders.
