We can download electronic control modules (ECMs) from cars and heavy trucks. Pictured is a Detroit Diesel ECM from a Peterbilt that was FedExed to us. Our turnaround time is usually less than one day. This one was received about 3pm, and was back in FedEx's hands by 5pm the same day. This was really important since this belongs to a one truck operation. We charge a fixed rate that includes the express, overnight shipping (which, in this case was $56). Our rate is less than 1/4 of what Mack charges to download Mack ECMs (they won't sell their equipment), and last time I sent one to them for a client, the turnaround was 6 weeks. We also have the equipment for Caterpillar, Mercedes, Cummins, and Volvo engines. The data recovered depends on the manufacturer, but Detroits can record about 2 minutes of data surrounding an event.
Here is a bench download of a passenger car airbag control module (the silver box). In most cars, this is where crash data is recorded. Here is a link to Bosch's site that lists the covered cars.
