MS3 pre-1.3 alpha3 released
This is a development code with a few experimental features. It follows pre-1.3 alpha2. A quick test run on my car appeared ok.
Main changes since pre-1.3 alpha2
New stuff:
Alt control. More code for lamp output. More code for on/off mode.
Pre-relay output for staging flaps.
High power time enrichment.
Specific shift light incl. gear based
Calculate Flex adjustment before starting too. Only calc flex on each pulse.
Long Term Trim feature
Oil pressure monitoring.
Bug fixes:
Fix int/uint comparison on log_trig_tps
MAP sample false error
Anti-lag correct input polarity on Nitrous-in pin.
Alternator TPS WOT wasn't signed.
Fix Subaru seq error.
ASE ini curve fix.
Minor:
ini ranges for on/off outputs
pwmidle_dp_decay_factor defaults to zero
Add fuel-pressure and alternator control fields to datalog.
ini tweaks for idle
gen_pwm default Y axes /10 to match scaling.
Remove "IAC cold position" feature. (Nobody understood it.)
Updated loaders to 3.26
Not fixed:
piledriver CLidle glitch (investigating)
elaw long starting (new)
Intermittent occasional very slow serial comms (need more data points.)
For discussion of specific new features or the above mentioned problems, please post in those topics.
NOTE! Tunerstudio 2.1.40+ is required. (http://www.efianalytics.com/TunerStudio/alpha)
Be aware that datalogging is broken in 2.2.03 (or thereabouts) so 2.2.06 is advised.
EDIT: Known bugs
Long-term-trim presently has a serious bug that can crash the MS3. This will be fixed. Do not attempt to use this feature in alpha3.
The zip is available to download at:

Re: MS3 pre-1.3 alpha3 released
Loaded and so far Alt function is flawless, logs will be in the Alternator post later. Only thing is I cant verify that the alt lamp works , if we could get it to light key on in the future that would be great.

Long term fuel trims has potential to be a big game changer. Now for some real world testing.

Re: MS3 pre-1.3 alpha3 released
The option of long term fuel trims needs to be grayed out if you have dual fuel tables turned on.
We need a CEL triggered by the average LTFT > say 10% or <-10% The OEMs do this to catch falling fuel pressure and that sort of thing.

James, the code is ok for sequential in subaru 6/7.
Thanks

Re: MS3 pre-1.3 alpha3 released
Strategy for oil press low? cut spark? or rpm limits?
Re: MS3 pre-1.3 alpha3 released
Yes the OEMs do have codes for long term fuel trim issues. The threshold is typically 20% to 30%. Long term trims can can be pretty handy for indicating vacuum leaks. Long term trim codes are second only to Evap codes as being a common cause for a CELwhittlebeast wrote:The option of long term fuel trims needs to be grayed out if you have dual fuel tables turned on.

Re: MS3 pre-1.3 alpha3 released
I had issues updating.
The install seemed to go fine all the way through installing the new .INI into TunerStudio.
After TunerStudio connected I had a ton of warnings, and then I had an error "can't compare data with controller" and it disconnected.
I tried to go back to a previous version but couldn't do that because I got "garbled response" messages.
Re-installed the latest version and the download again went perfectly, but same error in TS.

Re: MS3 pre-1.3 alpha3 released
safe to assume your running the latest TS beta ?

No, I had followed the link above and installed the alpha. I installed the beta per your advice and now it synched and started.Kemp3 wrote:safe to assume your running the latest TS beta ?
How does the latest TS 2.2.06 equate to 2.1.40+?? I'm confused by the version naming, perhaps.

Re: MS3 pre-1.3 alpha3 released
2.2.x is more recent than 2.1.y so if you need to use something at least as recent as 2.1.40 (which is what the 2.1.40+ means) then using 2.2.06 will be ok.hoveringuy wrote:How does the latest TS 2.2.06 equate to 2.1.40+?? I'm confused by the version naming, perhaps.

Re: MS3 pre-1.3 alpha3 released
The high power/time feature will be very wecome by the aircooled and esp. boosted crowd if it's doing what I'm thinking.
IIRC, for X seconds you can run the optimal performance(or emissions) "dyno" AFR, after that time it enables extra enrichment for plug cooling.
This is so you can run "normal" plugs and not melt them under extended WOT pulls.
(or rather, not have to run dead cold plugs all the time)
GM (at least) uses this strategy on their blown Caddys etc.
Looking forwards to playing with it.
(any way to tweak the timing along with the fuel when it switches?)
I have a ~decent PWM warmup setup as of today, will try before+after upgrade to A3.
(testing intermittent warmup issues requires... patience, 2-3 shots at it per day unless it's really cold out)

Re: MS3 pre-1.3 alpha3 released
I had also similar problem with TS 2.2.04 and alpha2 code. It disconnects very often and can't connect again until restarting TS. Sometimes it disconnects and reconnects again but it was almost impossible to work with it. Then I upgraded this morning to TS 2.2.06 and it was OK.hoveringuy wrote:I had issues updating.

Re: MS3 pre-1.3 alpha3 released
I had 2.2.04 which met the requirement for 2.1.40+, but nothing worked until I got the latest TS beta code. It also doesn't explain why I couldn't flash back to an older version (does it?)racingmini_mtl wrote:2.2.x is more recent than 2.1.y so if you need to use something at least as recent as 2.1.40 (which is what the 2.1.40+ means) then using 2.2.06 will be ok.hoveringuy wrote:How does the latest TS 2.2.06 equate to 2.1.40+??

Besides that, drove the car this morning and everything was fine. Looking-forward to playing with the long term trim!
Great job!

Re: MS3 pre-1.3 alpha3 released
I didn't know that 2.2.04 was broken, I have not used that version. The first post does say "2.2.06 is advised."hoveringuy wrote:I had 2.2.04 which met the requirement for 2.1.40+, but nothing worked until I got the latest TS beta code.

TS doesn't include a firmware loader (yet?) so it will have no effect on that issue, please provide more details and we might be able to help. You did use the newest loader to try and reflash the old code - right?

Re: MS3 pre-1.3 alpha3 released
I can confirm that the flex fuel sensor is now read before starting as well. However, flex does not appear to influence crank pw, making it very hard to start the engine. Can flex be made to adjust cranking pw as well?
If necessary, I can attach some logs as well, but it really only shows that crank pw is unaffected with and without flex enabled.

Re: MS3 pre-1.3 alpha3 released
Note that VEAL in TS seems currently unaware of the time/load based enrichment feature, and will happily "fix" your VE table for you if it's on.

Re: MS3 pre-1.3 alpha3 released
Possible bugs LEDs 14and 15 stay on all the time and 16 does not work. All are being used as default D14 is ignition and should blink when engine is running. It stays on all the time. D15 warm up enrichment stays on all the time. D16 accel enrichment does not turn on during times of accel enrichment. This was noticed with this release and the one before this. Also serious connection issues with the Bluetooth. If engine stalls or is turned off after initial connection TS will not reconnect. Sometimes it takes two or three times before this happens. Also have tried restarting TS still can not reconnect, rebooting the computer still can not reconnect. Eventually looked at the Bluetooth adapter when this happened and noticed the blue LED that blinks when not connected was on. TS not running LED stayed on Turn off computer LED stayed on. This happens all the time no matter where I am at. Once this starts only way I can get it to reconnect is to turn off the switch and turn it back on or unplug the Bluetooth adapter and plug it back in. I am using the Bluetooth adapter that is sold by EFI Analytics.
