I am wondering why the C7 has a electronic speed governor set at 190 mph. Was it decided that 190 is just much safer than 195, or 200, or unrestricted? I think this is really strange to add this when the cars will only even hit 190 in perfect conditions without mods as 186 - 188 seems to be around the real world top speed.
Maybe the tires aren't good for 190+? This would be important information for people tracking at certain high speed tracks.
it could be due to the tires for sure. Manufacturers will always make sure the car is limited to a top speed that is less than whatever the stock tire is rated for. Whether or not tires are the limiting factor on the C7, or if it's something else, I'm not sure.
One can certainly argue though, that doing 190 on a dyno puts a hell of a lot more stress into the tire than on the road surface...so they certainly are good for 190. Various dynos place a tremendous amount of different stresses on the tire, based upon their design makeup. That went a lot into purchasing mine, and will be a factor in my next as well. If it's good for 190 on a dyno, I'd think it sure as HELL is good for 195 on the street...that or they took that tire way beyond it's design capability, well into the "safety margin" designed into it.
I think it should be 215 mph . If i was in charge of setting the max speed limit for the car . I'd make it 215 mph 190 is like driving 15mph in a 35 zone to me . lol
Having the rear tires tuning at 190+ miles an hour and the front tires not tuning at all might be causing some type of hard coded ECU rejection. Would not be surprise.

The car is definitely going to suspect there is a major issue with the wheel sensors. This is how VW detected "test mode" on their diesels.

That's why the ABS light is illuminated in the picture. The easiest way to allow the rears to spin without the front spinning is to disable traction control / pull the ABS fuse / unplug wheelspeed sensors
Just because there is a message displayed during a dyno test doesn't mean there is a speed limiter when the car is being driven on a track with all 4 wheels turning.
Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below:
285/35ZR19 99Y 186 mph, 300 km/h
285/35ZR19 (99Y) in excess of 186 mph, 300 km/h

They are (Y) rated, which is good for in excess of 186. Y rating is just good to 186 continuous.
With a (Y) rated tire, usually the manufacturer knows how much in excess of 186, but it is not easy to access that information

Why is the car restricted to 190 mph?
190 is like driving 15mph in a 35 zone to me . lol
