NASCAR has issues with electronic fuel injection

efi

NASCAR’s switch to electronic fuel injection (EFI) this season seems to have fallen afoul of the law of unintended consequences. It appears there are some glitches in the system that were not uncovered in preseason testing. Uncovered so far are breakers that trip when drivers turn off the engine to save fuel, causing the engine not to re-fire.
This cost Tony Stewart lots of points at Phoenix. There are also reports of reduced fuel mileage when the system decides to run richer than intended. Jimmy Spencer suggested that NASCAR should have phased the system in, much as they did with the Car of Tomorrow, running only 10 or so races with the system the first year. It’s a bit late for that now, but he has a good point. On a related topic, Brad Keselowski’s use of his Iphone to tweet during the Daytona red flag has some folks concerned that the phone could also be used to alter the EFI control unit. There’s an app for that?

Jimmie Johnson’s No. 48 team has appealed the penalties levied at Daytona for illegal C pillars on their car. It seems that the car fit the NASCAR templates, but the pillars had been modified between template points. As I recall, there was a similar situation at Infineon with both the 48 and 24 teams a few years back, resulting in fines, point deductions, and suspensions. I doubt that NASCAR will allow the appeal, which is scheduled for 6 a.m. on March 13.
