According to records filed in the case, Achtemeier conspired with mechanics in garages and operators of truck fleets to disable the anti-pollution software installed on diesel trucks.

Coconspirators who wanted to disable their trucks’ pollution control hardware system—a process commonly known as “deleting”—sought Achtemeier’s help to trick the truck’s software into believing the emissions control systems were still functional, a process known as “tuning.”

Monitoring software on a deleted truck will detect that the pollution control hardware is not functioning and will prevent the truck from running. Achtemeier disabled the monitoring software on his client’s trucks by connecting to laptops he had provided to various coconspirators. Some of the coconspirators would pass the laptop on to others seeking to have the anti-pollution software disabled on their trucks. Once the laptop was hooked up to the truck’s onboard computer, Achtemeier could access it from his computer and tune the software designed to slow the truck if the pollution control device was missing or malfunctioning. Achtemeier could “tune” trucks remotely, which enabled him to maximize his environmental impact and personal profit.

The antipollution on a diesel engine (at least a big one) essentially reroutes the exhaust back through the engine and reburns it again. Before the antipollution devices were in place it wasn't uncommon for big diesels to get 500,000 miles before they needed to be replaced. Now with the antipollution devices they're getting somewhere in the neighborhood of 100k before they start having problems of significance.

Those engines and their maintenance are expensive as hell. It saves a whole lot more than the $4,500 having that done. It saves them hundreds of thousands of dollars over the long haul.
