MS3 Datalog Retrieval Speed, Up to 4X Faster
New firmware feature in MS3 1.3.x and upwards for uploading datalogs from the internal SD card to your laptop. This is applicable to all MS3 type ECUs running 1.3.x or newer firmware. All DIYAutoTune assembled MS3 type ECUs ship with 1.3.2 as of the time of this message.
There is now a setting under Communications->Megasquirt Baud Rate screen called "SDcard Readback Baud Rate". This can be set to increase the communications speed when pulling back logs from the card.
The default baud rate is 115200. These faster speeds can now be enabled:
Max speed varies based on outside factors, generally the type and quality of comms cables and any USB adapters used. All users should be able to select 230400, which will upload datalogs twice as fast as before. Try all settings and use the fastest speed that will work. 460800 should work for anyone using a direct USB connection and will deliver 4x faster datalog retrieval speeds than before.
Interested to hear success stories.
