LSA Supercharged 1972 Monte Carlo Hits The Dyno! Will It Survive?

Watch on YouTube

What happens here

After the unexpected reverse engagement, the dyno operator accesses the car's computer via his laptop to adjust the transmission tuning. He explains that he needs to modify the transmission's shift parameters to ensure it properly holds the selected gear and does not unexpectedly jump into reverse during manual gear changes. This process involves reviewing and altering specific values within the transmission control unit (TCU) calibration.

Goal: Resolve the unexpected gear shift issue.

Tools and materials

  • Laptop — Accessing and modifying vehicle tuning parameters
  • Tuning Software HP Tuners — Specific software for vehicle calibration (e.g., HP Tuners)
  • Vehicle Chevrolet — The car whose transmission is being tuned
