'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

Would you pay $17 a month to give your older Ford connectivity?

When it was first introduced in 2007, there was nothing like the original Ford Sync system, since it allowed car owners to connect and use a portable device better than anything that came before it. And because it was a brought-in/tethered and software-based system, Sync leveraged a device's connectivity and was easily updated. It took competitors awhile to catch up: Toyota Entune wasn't available until 2011, and Chevy MyLink didn't roll out until 2012. But now Ford is the one playing catchup since it stuck with the brought-in strategy while most other automakers were quicker to add connectivity via an embedded cellular modem. Ford initially installed 2G/3G modems in its small fleet of electric and plug-in electric vehicles starting in 2012 so that owners could keep tabs on charging. Embedded connectivity came to Lincoln in 2014, and Ford began adding onboard 4G LTE via Sync Connect to select cars starting with the Escape in 2015. To get more cars connected more quickly, last week the automaker rolled out its FordPass SmartLink solution that plugs into the OBD port of 2010 to 2017 model year vehicles. This lets owners retroactively get onboard Wi-Fi, set up a "geo-fence" to keep tabs on a car's location, receive vehicle health reports and allows remote engine starting and door locking/unlocking using a smartphone app, among other features. But to connect older Ford vehicles will cost owners $16.99 a month for two years, not including installation. Ford throws in 1 GB of data or a 30-day trial, whichever comes first, after which owners have to add the vehicle to their Verizon shared data plan, which supplies connectivity for SmartLink, or establish a new account. (Disclosure: Autoblog is owned by Verizon.) By comparison, GM's 4G LTE data plans start at $10 a month for 200 MB and goes up to $30 for 3 GB, and owners can also add a car to an AT&T shared-data plan. But OnStar doesn't have a separate monthly subscription for the embedded modem or an installation charge, and standard features via the RemoteLink Mobile App are free for the first five years of ownership. FCA's Uconnect Access service also uses an embedded modem to provide similar telematics features for $20 per month following a free one-year trial, while a la carte in-car Wi-Fi is offered for $10 per day, $20 per week or $35 per month.

GM tells owners not to use SUV wipers due to fire risk

General Motors is recalling 31,685 examples of the 2016 Buick Enclave, Chevrolet Traverse, and GMC Acadia because a short circuit in the windshield wiper motor can potentially lead to a fire. Due to the danger, the company is asking owners not to use the wipers until the problem is fixed, according to The Detroit Free Press citing the Associated Press. A manufacturing defect in the wiper motor cover means that the electrical terminals can come into contact and cause a short. The part could "melt, smoke, or catch fire," according to a statement from GM. The company will get them fixed immediately, and dealers will replace the cover. If there's bad weather at the time the owner specifies to get the recall work completed, the automaker will come pick up the crossovers. Depending on parts availability, the automaker will supply a rental car for customers, as well. The issue was discovered at the factory. According to the company's statement, only 6,405 actually made it to customers, and they were notified immediately by overnight letter. The rest were in dealer stock. The affected crossovers carry build dates between August 18, 2015 and September 24, 2015. Of those, there are 29,295 in the US and 1,073 in Canada. GM Statement: General Motors has told the National Highway Traffic Safety Administration that it will recall approximately 29,295 2016 model year Chevrolet Traverse, Buick Enclave and GMC Acadia SUVs in the U.S. because the front windshield wiper motor may overheat when in use because of a manufacturing defect. In some cases, the front windshield wiper motor cover may melt, smoke or catch fire. The approximately 6,405 customers who have taken delivery of these vehicles were notified by overnight letter and are urged to contact a GM dealer as soon as possible to arrange a service appointment. These customers should not use the front windshield wipers until they have been repaired. If weather conditions prevent driving the vehicle without using the windshield wipers, GM will arrange to pick up the vehicle for servicing. If repair parts are unavailable, GM will provide a rental car at no cost until parts become available. The total population, including Canada, Mexico and exports, is approximately 31,685. About 25,280 of these vehicles are in dealer stock and will not be sold until repairs are made.
