Engine Maps Explained

by:

In my last post, I detailed how the relays in the ECU system allow the system to flip to a default engine map. This lets the team keep running, even when something fails, and it decreases the chances of the ECU doing something that blows up the engine. Here’s a short explanation of what exactly an ‘engine map’ is and what it does.

Phoenix: Relay Race?

by:

The race at Phoenix was the first non-restrictor-plate race. A number of drivers experienced engine-related problems, leading some media outlets to start blowing the “EFI problems” horns as loudly as possible. Mark Martin, the pole sitter, was an unfortunate casualties of a “flipped circuit breaker”. One of the most interesting exchanges to me was a series of tweets and a radio interview with Mark Martin’s Crew Chief Rodney Childers (@rchilders55) in which Childers repeatedly said it not “an EFI problem”, the radio commentators persisted in saying that it was.

The Math of Fuel Mileage

by:

I guess when you have people feeding you all the numbers you need through your earpiece, you think they’re easy to come by. That’s the only explanation I can figure out for the snarky comments by television commentators about crews not being “smart enough” to figure out how much gas to put in the car so that it doesn’t run out before the end of the race. There have been a lot of fuel mileage races the last few weeks. Pocono is traditionally also highly likely to be a fuel mileage race, so let’s clarify how easy (or hard) it is to not run out of fuel.
