With a PowerLogger you can show wideband and boost on the Scanmaster.
PowerLogger update rate is 16 frames / second. ALDL update rate is 1 frame every 1.5 seconds. There is the "fast data stream" that I developed for the chips, its update rate is 2 frames/sec for O2 and knock retard, the rest of the data is slow.
You can log either way to an Android device, without a PowerLogger the stream only contains ALDL information which is limited and slow. With a PowerLogger, you get all the ECM information, the 5 analog inputs, lots of speed, etc.
