MS3 pre-1.4 alpha 3 released

Post by jsmcortina »

To announce the release of "MS3 Pre 1.4 alpha 3" - this is a new stream of development codes.
ETA on this 1.4.x code becoming release is 6-12 months.

Who should use this code?
Experienced users wanting to test the new features.

Who should not use this code?
New or casual users - please use the current release code instead - see the Downloads page linked above.

Main changes since pre-1.4 alpha 2
Many of the bug fixes are the same as applied to 1.3.x
Bug fixes:
Fix MS3Pro HEI bypass polarity issue.
Roving idle only works if anti-lag on.
-Enable C.O.P. watchdog timeout
-Apply timeout to SSEM.
-Apply timeout to fire_n_check.
(The above three these changes were to fix/mitigate a lockup discovered in RB25 mode.
The code was getting stuck in fire_n_check waiting on the XGATE.)
Fix on/off idle output.

New / changed features:
Allow FP to be pulsed in I/O test mode.

Tooltip tweak.
Minor tweaks to usage of vvt_decoder variable.

The firmware zip is available from:

Hi,
Could it be implemented to get the CEL Blink-Code as CAN Message? Would be great for displaying Errors in the Dashboard. Why not thinking about a generic error code scheme (including CEL, Sync loss+reasons etc.)?
Thanks and regards, Thomas

It already is or can be.
Field cel_errorcode in the realtime data.

Any body having download of SD data with 1.4.2 or 1.4.3 ? Two different bikes and data takes at least 10 attempts to do a complete download. Freezes up on the time line bar. Switch back to 1.3 versions and it downloads fine.

Did it a couple of times. No issue here...
Thanks James for pointing me on CEL Error code. I think I have overseen it because I only looked in tunerstudio, not in the pdf. In TS it says (because of small typo) t.cel_err which made me not seeing it...

Investigating.
EDIT: I know what is causing this, working on a fix.

The files you sent me didn't work either. Also my water inj duty went away in data log too. Going back to a regular firmware for now. It is interesting that the NOS bike works with a 1.4.2 that tony sent me with the new rev limiter and it data logs. I seemed to have lost that zip file.

pre-1.4 alpha 2 should download from the SDcard ok. The change was to enable the COP watchdog in alpha3. I wasn't resetting the watchdog timer in the SDcard code, so it tripped and reset the processor. (You would see "Seconds" go back to zero.)

Before sending the files, I tested numerous times here and the behaviour changed from never working to always working.

I wonder if I sent the wrong files? I've been re-testing and the SDcard downloading is working fine. The code version in the title bar of TunerStudio should show as
"MS3 pre-1.4 alpha 4 20140821 14:06BST (c) JSM/KC ********"

James,
I do not recall the firmware updating to 1.4.4 It just said it was the incorrect ini or something like that and would jump back to 1.4.3

If you send me the other ones could you also include the data log for water inj duty in the same file ? for both ms3 and pro
Thanks, Jeff

I have been away racing on "pre-1.4 alpha 4" and took a 130 mile test drive back on "pre-1.3.3 beta 3". Both seemed fine, but when doing a final test on the SDcard download fix, I hit the same problem again when using 230400 baud, so I need to do more validation on my "fix" as it is clearly not resolved yet.

There should be a new alpha out in the next few days and the water duty datalog fix will be in there too.

Great news. My car has been down from a bent mainshaft in the tranny and it will be back in this weekend. I'm still on 1.4.1 and will be happy to upgrade to the next round of code
