MS2/Extra pre-3.4 alpha 9 released

[jsmcortina]

To announce the release of "MS2/Extra Pre 3.4 alpha 9" this follows pre-3.4 alpha8

ETA on this 3.4.x code becoming release is 3-6 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-3.4 alpha 8
Bug fixes:
Allow loggers in passthrough (MSG_REQX)

Changed features:
Tweaks to CAN code.
Cam sensor / MAP sensor UI, tooltip and config error message tweaks.
Grey out and ignore cam input setting in "Single Wheel" mode.
Remove most of old MS2/BG EDIS interrupt code to eliminate divides. EDIS now implemented like MS3 and uses standard noise filter setttings. Tests ok on bench, but requires on-vehicle testing. *CAUTION*

Minor/internal:
Serial debug not compiled in by default.

As per alpha8, this firmware includes a big re-write of the CAN system which we believe gives far more reliable passthrough operation.
The EDIS re-write needs on engine validation. EDIS users MUST re-verify their timing with a strobe.

The zip can be downloaded from:
http://www.msextra.com/downloads/dev/ms ... 4/alpha-9/

Be sure to read the RELEASE-NOTES.txt and README.txt. Especially note that "Not Synced" has been renamed to "Not RPM synced".

The current TunerStudio (2.6.0 or later) is required.

tested and works as fine as alpha8, e.g. CAN Realtime Data Broadcasting to the Dash2Pro with 10Hz - nothing odd found so far.

Attached msq and some idling-revving log data: appreciate if find-advice on abnorm settings etc.

Thanks James!

Changed features:
Cam sensor / MAP sensor UI, tooltip and config error message tweaks.

James

Tooltip says to "Set the MAP sensor phase threshold on the General settings page"; the threshold setting option is on the [MAP Sample Settings] page.

Fixed for next release.

Remote digital inputs and outputs (CAN) don't work for me.

ADCs, passthrough, etc, all work fine.

I flashed the MS2 back to 3.3.2 and it worked again.

[jsmcortina]

Yep, something isn't working right there. I'll email you a test code shortly once I've fixed it.

James

[Reverant]

Replied.

[jsmcortina]

Did you get this working ok? Jean and I tested and all seemed ok after the fix.

James

[Reverant]

The 2nd s19 you sent me didn't work as well.

[jsmcortina]

Weird.

James

[Reverant]

Well I found my CAN analyzer so I'll be able to track it down shortly.

why can't I download this zip?
the page just got missing.

I edited the first page with a new URL.

Is it possible to have something similar to CAN broadcast but for the serial port instead? Have the option to pick a handful of offsets from outpc and send them to the port?

[jsmcortina]

If you did, there would be no way to stop it without using the boot jumper. So I don't think that's going to be possible.

James

[ol boy]

Sending a "Q" or "S" to stop that function wouldn't work? All the tuning softwares start by asking "what are you?" before asking for the pcoutput. The same thing could be done before loading new revision over serial.

[jsmcortina]

The serial is effectively half-duplex - it can't receive while it is sending.

James

What is your intended application for this? Are you building something or do you want to interface with an existing device that only has a serial port and can only receive data?

Jean

[ol boy]

Yes, I'm building something. Our hobby efi unit is about ready to fly and we are looking to data log the history of the engine and store a few basic parameters onto an uSD card. I'm working on the uSD logger to capture the full pcoutput but it contains large amounts of unused data space. Unfortunately the uSquirt module version we bought does not have the CAN hardware installed..

Unfortunately the uSquirt module version we bought does not have the CAN hardware installed..

Is that a modified board? I have never heard of a module without the CAN hardware. Even the pre-production units had it. I guess it's possible there were custom batches made with unpopulated CAN circuits but I fail to see why that would makes sense since the cost of the components is very low.
