We are pleased to announce MS3 pre1.1 alpha18
The largest user visible change is that the SDcard interaction now available in TunerStudio. The firmware already had these features, but they weren't easily usable. Over the last month of so Phil has been adding them to TS and I've been working with him cleaning up some firmware issues that were exposed.
Also included are our revised firmware loaders for Windows and Linux. (The old ones are included too in case of problem.)Main changes since alpha17SDcard / real-time clock:
Lots of SDcard/serial work, mostly not very user visible.
Use new SDcard/RTC menus in ini.
Set-clock command forwarded to Extender if enabled.
Maintain pseudo-time if no real RTCC enabled.Ignition/wheel decoder:
Twin trigger, fix some breakage, add spkcut.
Subaru 6/7 tooth no. fix from MS2/Extra
Re-write Optispark decoder. Stim tests ok.
Re-write RB25 decoder and adjust offset. Stim tests ok.
Re-write Nissan 16-12-8-4 and rename to SR20. Stim tests ok, but phasing unknown.Idle control:
Fix a few CL idle bugs.
Forward port gslender's "sliding window" for RPM input to CL idle.
Add dashpot that closes in at a variable speed inversely proportional to -rpmdot
Add RPM-delta based idle advance ability when using CL idle
Fix some AC idleup bugs.
Change the name of "crank to run taper" to "crank to run delay"New AE:
New AE set the engine bits properly.
Add CLT % for new AE
Fix MAPdot accel in new accel algorithm. The "dots" were off by a factor of 10
Closed loop idle timing assistance is now named Idle RPM Timing correctionOther:
New averaging MAP sampling.
Add MAP logger, similar to tooth loggers. (Not yet supported in TS.)
Traction control - VSS1/VSS2 checks threshold and add TPS/MAP minimum settingsInternal/bugfix:
Internal streamlining of outpc readback code (~1ms -> ~500us)
Range check 'k' command to prevent illegal read.
(Also workaround gcc sign extension bug.)
Config error checks on dual-fuel / staging.
Added printf() equivalent and implement log buffer via 'D' serial command.
Increase default cranking rpm setting to 700.
As usual, be sure to use the latest beta TunerStudio. 1.21
