The most active BtSsm thread with best information is over at LegacyGT.com, and for 2015+ WRX details seems like most info can be found only on various FB groups.

1. Latest status is 2015+ WRX ECU logging is fully* functional, TCU allows for single field monitoring (CVTF Temp by default since its the only useful param anyway)

* given the limitations of what Subaru pushes to the CAN bus via SSM on these newer cars (effectively all Hitachi based Subarus, most 2014+ models across the range).

Subaru is phasing out SSM and switching to E-OBDII (Mode 0x22 and 0x23) for many/ most of the most useful params. Because of this in ECU mode you can log most but not all params available via COBB AP or Ecuteks logging solutions.

2. See Bellipoten's videos on Youtube, build thread here, FB group, etc. Effectively most useful params fom IAM/DAM, FLKC, intake/exhaust VVTs, OCVs, OSVs, AFRs or Lambda readings, Fuel Learn/Correct #1/#3 params, RPM, Load, MAF Vs and g/sec, Boost, CL/OL flag, Fuel Targets, Intake Temp, Coolant Temp, Fuel Temp, Battery Vs, Front AF Sensor and Rear O2 sensor Vs, Ohms, various duty cycles.

Cant monitor/log Engine Oil Temp, FKC, Boost Targets, Boost Error, AF Error (self calc via Excel), Manifold Temp, EGT (estimate). Cant pull LVs (Learned Value snapshots).

3. For a Hitachi based car like a 2015+ WRX, best option is to go wired (Tactrix OPv2, USB OTG adapter, Android tablet/phone). Otherwise the only real option is an OBDLink LX or MX with beta firmware which add support for SSM over CAN.

Logging speeds in wired mode are faster than COBB AP, fast enough for e-tuning (>40-60Hz for ECU logging depending on how many fields you log, >100Hz for TCU logging).

BtSsm is an excellent tool, but does require some upfront learning. Good luck and enjoy it if you opt to purchase the app, its worth every dollar and were it not for Subarus data acquisition and engine/transmission management decisions and contracts, it would be just as exhaustive on the newer Subarus as it is on 2004/5s to 2014s (where its far superior to COBB or Ecutek logging solutions, better than FreeSSM and RR, ECUEdit loggers too).

Indeed. Quote from last year posted above with emphasis... good luck bro.

I used to use a OBDLink LX (or MX...)...PM if you want to buy it (does not have the beta firmware, tho).

has anyone figured out how to get this to work with a 14-18 FXT yet? does it just need an ecu that's been tuned or something?

Thanks man, I had the LX before buying the SX but like the idea of it direct wired. Maybe I'll as my buddy with my LX to let me borrow it and test the BtSSm app and see if i prefer it over the obdlink app itself.

Appreciate the find. Guess i can try to return this vagcom cable...

Vag com kline will NOT work for newer SSM over CAN only Subarus.

aka 2015+ WRX, current/last gen FXT, 2015+ Legacy/ Outback, Ascent, etc.

OBDLinkLX, MX, maybe their new wired SX too. Or Tactrix OPv2 + Btssm and youre set.

Unrecognized ECUID/CALID?
Just create a 'BASIC' alias and monitor and log away basically just as fast and as much as on an AP.... without an AP... with or without a tune, regardless of if its locked, COBB, Ecutek, Epifan, etc.

No tune needed, in fact its a great way to log and monitor the stock tune on any Hitachi ECU/TCU Subaru.

What revision and firmware on the tactrix? If its older than Rev H, or hasnt been plugged into a PC running EcuFlash recently, download the latest EcuFlash, run it, connect up your Tactrix and save the app log, it will show the firmware ans hopefully that it updated it.

You need this (now old) 2016 firmware for proper Hitachi ECU/TCU suppprt and handshakes.

Without it, even a Rev H device might have an old firmware and will not play nice with your FXT ans BtSsm app.

From Tactrix site...

-Added SH boot mode support for SH725XX processors.
(User Boot MAT is still not supported yet pending read support for this area)

-support for 2015 WRX with Hitachi ECU

-support for OEM reflashing of BRZ

Also, while using BtSsm under Settings and ECU interfaces, Im assuming you set the last option: 'OP2.0, usb+otg, CAN
(2007+ patch required)'

No ROM patching required for the 2014/15+, only Denso based cars which want to monitor/log over CAN.

It's rev. E, does that mean it won't work?

if this matters

I think the firmware is OK, but regarding Rev E hardware working or not - ping the Tactrix bros.
They'll know right away I think.

Bellipotens and I have Rev H devices (fairly old purchases actually)
so that's all I'm familiar with.

BtSsm dev can also send you a USB packet sniffing program to help troubleshoot.
It will make it fairly easy for him to tell if the app is able to communicate with your CAN bus at all.

Thanks for your help. I'll have to ask those guys.

I bought my tactrix around 2012 I think for my 2011 wrx.

Just got an OPv2 in and bought the app. Really liking the ability to log/monitor without having to flash. Next steps will be to add the fields that weren't included in the BASIC configuration.

Anyone know if there is a thread for this app regarding adding additional custom parameters from romraider.

Im Looking for a database of all the definitions input to add and each individual will supply their ecu ID I believe.

Ex: adding in Boost Error, Final Fueling Base, etc

NASIOC isnt the place. The biggest and most complete threads re BtSsm can be found where all the action happened - over at LegacyGT

https://legacygt.com/forums/showthread.php/btssm-bluetooth-adapter-app-v-1-closed-229709.html

https://legacygt.com/forums/showthread.php/btssm-bluetooth-adapter-app-v-2-267811.html

Adding custom fields is easy, you just have to know what you're doing. Some trial and error, etc.

1. Grab the latest RR logger def XML and/or the memory addresses for your ECU/TCU IDs from their definition threads.

2. Locate the enhanced and engineering params (1/2/4byte) you're interested in, unit conversion you want, etc.

3. Define the custom field in BtSsm (use examples from the btssm.com guide or scattered across the hundreds of LegacyGT thread pages)

4. Enable the field/s for monitoring or logging and see if the values it returns while the engine is running fluctuate within reasonable min/max brackets.

BtSsm does not yet support multi-PID referential fields, like Boost error or AF Error. For those just setup and log all constituents and calc thrm yourself in new columns in Excel.

I have a question about the accuracy of IAM (Same is DAM) in BTSSM.

I have the latest version of BTSSM and OBDLink LX using CAN to connect to my Stock 2016 WRX, using the BASIC Profile. I noticed that IAM does show up for me, and doesn't require any tweaking to get it to show.

My concern is that my IAM values in BTSSM indicate a pretty big problem, so I am not sure if my car really has a problem, or if BTSSM isn't displaying IAM correctly since I am using the BASIC profile. When it started monitoring it, it read .688, but during my 45 min drive home, it dropped to .500, and stayed there. The value would intermittently fluctuate up and down, but settled at .500. I didn't notice any drive-ability issues though. I also tried resetting my ECU by pulling the battery cable for 30 min. After that IAM showed 6.88 again, and actually raised to .750 then .860, but eventually incrementally fell down to .500. It seems to always drop when the AC is on, but I never notice any driveability issues.

Since it fluctuates, I am assuming it is reading some data, but with how it drops without driveability issues, and the fact that it didn't go to 1.00 after the ECU reset, I wounder if it isn't providing accurate data.

Should I be concerned, or just write it off as BTSSM not reading the data correctly?

I believe your IAM readings are correct. And the fluctuations do not indicate a big problem.

Contrary to popular (ugh) belief - a 'rock solid' IAM/DAM pegged @ 1 does not constitute a great running car or perfect t00n (its a gross oversimplification to assume this is the case).

And sadly, a IAM/DAM fluctuation, especially on the newer (2014+) Hitachi ECU based Subarus also does not constitute an immediate issue or major problem, bad gas, bad t00n, bad anything. In part it is what it is, and functioning as intended (at least in stock trim)... the D in DAM stands for Dynamic and that gives a little hint as to what it should be doing.

It would be great if someone who has access to ATR could pull up a Stage0 t00n base and KCA timing tables, blend them to arrive at a total timing surface and then vary the resultant total timing to give people a sense of what a IAM/DAM at 0 vs 0.25 vs 0.5 vs .688 vs say 1.0 results in.

I would not be surprised if the total timing in the DD RPM/Load ranges isn't affected all that much. Perhaps even under higher loads, the diff is just a few degrees.

Without this knowledge on either the stock t00ns or any OTS or pro-tunes - the impact of IAM/DAM fluctuating (everything else held constant) can't really be quantified.

It may be a fair bit of pulled timing or very little to none at all.

this is good stuff. been hoping to find a way to log on my phone.

I have an openport 2.0, Oneplus 6T phone. Just need the app and a mini usb to usbc cable.

for the guy saying it wont log past 22psi. I had that issue in romraider, needed to select the "direct" option. maybe just an address change in btssm app. I run 30psi so know your pain

Are they simply just illustrating how to add new fields for carberry features like flex fuel?

Does it mean that the ECU ID that carberry runs off is already fully supported?
thanks for this. I run carberry, also using maf input for innovate lc2, tgv for fuel and oil pressures. Going to start playing with this.

to get past the 22psi max, i think i can update the PID with this info?

<ecuparam id="E21" name="Manifold Relative Sea Level Pressure (Direct)*" desc="">
<ecu id="3D04EA4605">
<address length="2">0x200EA</address>
</ecu>
<conversions>
<conversion units="psi relative sea level" expr="(x-760)*0.01933677" format="0.00" />
</conversions>
</ecuparam>

Has anyone figured out how to get this working in a 14-18 Forester XT yet. I know there was some research I needed to do to get it working but I've been too lazy.

Also how come no of these obd2 apps can show tire pressure or reset tpms? I feel like a lot of people would pay good money for that. There must be a way since it the tpms is reset through the obd2 port.
