Magden
Another OBD II–capable datalogger is the M.1 Performance Computer from Magden Technologies [(949) 599-0301; www.magden.us]. This system can read data from a factory or aftermarket ECU and add up to 11 analog and four digital imputs and download all of it to a personal computer over USB. You can view the data in-car with Magden’s touch-screen or another compatible video screen. Besides all the performance logging, the M.1’s display graphics can even be customized to match a car’s interior.
