Maybe if I were an avid NASCAR fan I would understand the reason for all the security issues surrounding the processor. Why should the software controlling engine performance be considered differently than the many mechanical tweaks used to outperform competitors? Engine performance ultimately hinges on the mechanical design anyway, so software changes can only go so far to improve performance until the track is littered with pistons.

Way to lead the way NASCAR! Quote: Carburetors were the usual fuel delivery method for most U.S. made gasoline-fueled engines up until the late 1980s, when fuel injection became the preferred method of automotive fuel delivery. In the U.S. market, the last carbureted cars were: * 1990 (General public) : Oldsmobile Custom Cruiser, Buick Estate Wagon * 1991 (Police) : Ford Crown Victoria Police Interceptor with the 5.8 L (351 cu in) engine. * 1991 (SUV) : Jeep Grand Wagoneer with the AMC 360 engine. * 1994 (Light truck) : Isuzu

Interesting. Technology of NASCAR has moved from car companies to OEM. Good one for both. Let us know who makes what injection chips on the cars.

What a great move on the part of NASCAR! I wonder what type of innovations we will see as a result of the switch to fuel injection? Nice partnership deal with Freescale as well, I am sure the marketing group is ecstatic. When will we get more details on the engine performance changes now with the new system? Looking forward to the new more realistic racing platforms.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
