ca aplicatie
http://www.btssm.com/ poate fi configurat sa citeasca toate informatiile pe care le poti loga si in romraider logger .... pe scurt adresele din definitiile romraider le poti defini si in btssm
dau cu copy paste un mic tutorial in engleza mai jos:
What you will need:
•Android Phone or Tablet (I am using an older LG G3 as a test, running android 5.0.1)
•Btssm app (
http://www.btssm.com/ )
•OTG cable and tactrix or btssm bluetooth dongle (I am using OTG usb cable and the Tactrix)
•(optional) Flex Convertor speed density harness with 5v input (discontinued??)
As Carberry is based off a JDM ECU with the ecu id of 3D04EA4605, it shares lots of the memory read definitions off that ECU. However, you will need to input custom definitions for specific Carberry stuff (like ethanol content)
In Field Chooser, you go to Add at the top right, this will allow you to add a custom field. Using Ethanol % as an example.
1.Name you will input is Ethanol (%) (or E (%) basically whatever you want to call it)
2. Addr (hex) (this is where you tell the program to start looking at on the ECU’s memory to find the value we are interested in, in hex value) which is: 021030
3. Length is how long (bytes) the information is so it knows what address to read up to) which is: 2
4. For formula, you are telling it how to interpret that value found starting in 021030 and ending 2 bytes later: x/655.36 (where x is the value found in the 2 bytes from 021030)
5. Decimal places are to display how many decimal places to display. 1 is like 10.0, where 2 would be 10.00. 1 is sufficient
6. If all you want is the text readout, you can zero everything else (gauge min, max, #) and hit save. It will still read and log perfectly. But if you want to have the option to have the gauge style readout, follow the optional steps.
Optional steps: For those wanting the gauge display
1. Gauge min set at 0 (this is the lowest value the gauge display will read)
2. Gauge max set at 85-90 (this is the highest value the gauge display will read)
3. Gauge # every set at 5 or 10 depending on how you want it to be broken down.
Again, this is optional, doesn't affect logging or the text output.
Now the best part, because we can add custom definitions, we can use the 5v input from the maf as an input for sensors if you are on speed density. Those of you that have TGV inputs you can also use those (if your TGVs are deleted) as a 5v input.
For example, Innovate Wideband MTX-L connected to the maf 5v input. The MTX-L has a linear 5v output so you can use it in the formula y=mx+b where y is the value we want (AFR), m is the slope, x is the voltage, and b is the intercept on the X,Y graph.
1.As above, go to add custom field.
2.Name will be WB (AFR) or WB AFR
3.Addr (hex) will be 00001D and length will be 1 (this is the address for maf sensor voltage)
4.Formula, so looking at our y=mx+b, we know x is voltage so we will have that as (x/50), innovate states that by default the MTX-L’s output at 0v is 7.35 AFR and 5V is 22.39AFR, we can calculate out m is 3.01 and b is 7.35. Thus what we need to put in the Formula is (3.01*(x/50))+7.35
5.I think you can fill in the rest from here
For non-linear output, BTSSM has optional lookup tables you can put in, but using a linear output means you can also edit your current romraider logger definition file to log from the 5v inputs as well.
For reference:
Right TGV Sensor voltage: Address is 021750 length is 2, and formula for voltage is x*0.0000762939453125
Left TGV Sensor voltage: Address is 021744 length is 2 and formula for voltage is x*0.0000762939453125
Depending on how much I like it, I will be installing an android tablet permanently (and post another how-to) to act as a logger and full time SSM display. Only thing missing is the ability to flash maps (it is possible to flash an ecu off an android phone, look at MHD app for BMW N54 engines)
Q&A:
1) Why BtSsm and not Torque?
a. This is because BtSsm was designed to use the SSM protocol designed by Subaru, and in conjunction with the tactrix or the btssm module it works in SSM continuous data push mode (which means very fast). Torque can use SSM with the very expensive OBDKey but it does not operate in continuous data push mode.
One of the sample logs I’m posting (not mine) has 19 fields to be logged, and read the samples 15-16 times per second. That is VERY FAST.
b. BtSsm allows custom fields if you know which memory sectors to read, Torque does not.
LE: ca paranteza, nici eu nu stiu sa aiba EJ-ul sensor OEM de temp ulei ....
