Just for "laughs" I connected to my '19 ZR-1 to data log the engine controls and was surprised on how little I can read of the data stream.
For example, the E99 apparently, will send no knock sensor data at all...no knock signals, no knock retard...in fact the only piece of data the E99 sends that is spark related at all is SAE spark advance.
Why can't ECM Scanner read at least as much data as I can get out of the E38 in my ZO6.
