New serial / alpha12 releaseRequirements:
You must have been running alpha11 successfully before trying alpha12
Tunerstudio beta >= 1.074 is needed.
)Major changes since alpha 11
New serial protocol.
All transactions to/from the MS3 are sent in CRC checked packets. The aim here is to eliminate the uncertainty that was present in the existing serial system. This involved almost a complete re-write of the serial system. A full transaction is read into memory and then processed if the packet passes size and CRC checks. (Previously the serial was handled on-the-fly with no checking.) This has removed most of the interrupt-side serial code and it is now handled in the mainloop.
Testing by JSM/KC/PT so far seems to be positive, but wider field testing could easily reveal unexpected issues - be careful !Small changes:
Add option to only correct in EGO between a specific threshold.
Add CLT lower threshold, below which wastegate is held open.
Add option to turn on fan with AC button or not.
ini tweaks per PT
V3 board injector testmode 'all'
Firmware loader allows tune to be refreshed while preserving sensors and is more verbose about what it preserved.Known issues
The firmware loader isn't 100% perfect at detecting between old and new serial formats, more work required.
Megaview will not work yet.
SDcard serial utility programmes will not work yet.
JBperf IO-Extender time-set utility will likely not work. (untested)
Any other utilities, loggers or dashes that use old serial will not work.
