Re: Engine Died at High Speed
The one piece we are missing is whether a tuner had been in there. My owner's manual calls for Z-rated tires (149 mph) so at 144 the speed limiter should not have kicked in with the factory program. OTOH if that was read from the speedo, who knows what the computer thought the speed was. Have not seen a disassembly but in my GM computers there is a fuel cut off speed and a turn back on about 5 mph lower.
Also there is " The traction control indicator turned on and the color was orange (not yellow). All other warning lights came on while the car was in-gear." but no CEL or codes ? That sure sounds like the computer crashed and reset when started.
ps Have been at or over that speed many times (used to race Corvettes). Am more concerned about tach, oil, and temp than speedo.
