Hi folks, Download from here - http://www.audiobanshee.com/software/TeslaLogs.dmg This is Version 1, but really should be 0.8 or something. It should run on Tiger or newer, and on PowerPC or Intel. I'll try to quickly go through the strange stuff first, followed by a brief guide. [EDIT: This is now Version 2.25 - see the latest ReadMe for up to date descriptions] A) To view VehicleLogs, you must first use the OSX Finder to uncompress the .tar file and then drag the corresponding top directory onto the Tesla.app icon. Something about NSDocument does not like opening a directory instead of a file, especially without a package extension, so I'll have to fix this later. B) There is a Charge Log window and a Drive Log window for each Vehicle Log directory that is opened. It seemed too crowded to merge both, even though you obviously cannot charge and drive at the same time. 1) The Charge Log window ends up with the directory name, which is in the YearMoDaHrMn naming convention showing when the Roadster created the tar file. a) It shows battery charge level in green as a percentage, with a legend for 100% (full range), 85% (full standard), 70%, 60%, 50% (long term storage), 25%, 10% (warning level), and 0% marked. b) Charging voltage is shown in orange, with 240V, 220V, 208V, and 120V marked on the legend. c) Charging current is shown in red, with 70A, 60A, 48A, 40A, 32A, 16A, and 12A marked on the legend. d) Available charge current is shown as a light orange background behind the actual charging current. The logs only update this value once every 30 minutes, so the end and sometimes even the beginning times can be delayed, and gaps may be apparent even though the disconnect was only brief - I'm at the mercy of the information available in the log. This value shows the 'maximum' available, although sometimes you'll see actual current briefly go above this maximum. 2) The Drive Log is a bit too busy at the moment, what with the VehicleLogs having values that are updated for every second that the Roadster is on. It can be tough to scroll around through such fine detail, especially if your Roadster sits off for long periods of time. a) ESS Voltage is shown as a light orange background behind any time range when the car is on. There is a mark for 400V in the legend, which seems like the typical level, and you can see battery voltage dip whenever massive current is pulled. b) ESS Current (in red) is positive during regeneration and negative during normal driving. Regeneration seems to be limited to around 100A, which is marked on the legend, but performance can pull as much as 800A. There are markings for 0A, -200A, -400A, -600A, and -800A on the legend. c) I chose to scale the Speed data (in blue) such that the 160 mph speedometer maximum is at the top of the window. There is a marking for the maximum actual speed of 125 mph, along with 100 mph, 80 mph, 60 mph, 20 mph, and 0 mph. d) Torque is shown in purple, but there are no markers since I didn't want to crowd the legend with Newton-meters and/or Pound-feet. Future versions may make this clearer. e) Accelerator pedal position is shown in green, scaled to the height of the window. Flooring the pedal will graph at the top, while completely releasing will appear at the bottom. 3) Both windows allow zooming out with a mouse click, zooming in with a right mouse click, and fine control over zoom via the mouse scroll wheel or two-finger scrolling on a multi-touch trackpad. The height of the graph always scales to full window height, but the width allows zooming and shows the Month and Day along with tick marks for Hours and Minutes. There are some drawing errors when scrolling, but resizing the window will redraw the date legend correctly. There is obviously much room for improvement.
