G8 Issues

Lee,

In 3 words - PRODUCT LIABILITY LAWYERS. For quite a few years GM has speed-limited their cars to match the speed rating of the tires installed on the car.

I'll bet before too long someone will have a software hack for the PCM to disable the speed limiter.

There won't be a "software" hack. You need the tool that can program the PCM. Grand AMs have been this way since '99, and to override the limiter you need a specific tool. One that I know is an HP Tuner.

I understand the tire correlation. My SSEi has "H" rated tires which warrant the 130 mph governing. However, no tire speed rating tops out at 135 mph.

Must be something else.....like the lawyers.

Or the insurance companies.

Then why don't they put on higher speed rated tires. A vette isn't governed. Anyone buying these types of cars wants maximum speed, they aint buying to have the speed limited. Liability is the drivers responsibility not the manufacturers.
