no problem man, i actually LMAO on that

 

hey hamish, i download the one from this thread that SIC posted on page ten since i couldn't get yours cuz of the invalid link. I'll try it out today and see what happens

 

so if i plug in the right xml to the datasettings file then i should be able to open up my past logs and they should show something right?

It's NOT doing it though? what the hell am i doing wrong?!

 

Your old logs won't work since they didn't have the right XML. You have to go and take new logs with the new XML so that evoscan stores the right parameters.

 

Hi Tephra,

Could you help me in figuring out the address for the IAT #2 sensor which sits in the intake manifold (not in the air intake) for USDM 52680018? This would be very helpful in figuring out air temps based on boost. Thanks!

INTAKE AIR TEMPERATURE SENSOR 2
Intake air temperature sensor 2 is installed in the intake manifold. Intake air temperature sensor 2 detects intake air temperature in the intake manifold through thermistor's resistance change and outputs the voltage according to intake air temperature in the intake manifold to ECM. ECM uses this output voltage to compensate fuel injection control. Sensor properties are as shown in the figure.

I couldn't find anything in the FSM for MUT or PID for IAT2, but I did find this in the On-Board Diagnostics table:

Parameter: 68
Description: Intake Air Temperature
Common Example of General Scan Tool Display: IAT: xxx°C (xxx°F) IAT2: xxx°C (xxx°F)

So it looks like OBD should have the capability of returning both IAT and IAT2?

 

How are you guys getting nice graphs? I'm just getting a XML file...no graph....I know I'm missing something stupid and small, LOL.

 

you should be getting a CSV file and then importing it into Excel or some other program and creating a graph of the data.

 

Whats the easiest and best way to make a graph? I see you now have to manually create it...

 

you can view the graphs through evoscan, there is an option on the tabs

 

So if you don't have EvoScan you can't make nice graphs like shown?

 

you can make them in excel i am sure.

 

IAT = MUT11 - 40 this will give you the celsius temp
take that figure and multiply by 1.8 and add 32 to get the farenheit temp.

So in Evoscan it should be this for USDM 5268 series:

<DataListItem DataLog="N" Color="" Display="Mode23 IAT" LogReference="Mode23IAT" RequestID="23808659" Eval="(x*1.8)-40" Unit="Deg F" MetricEval="x-40" MetricUnit="Deg C" ResponseBytes="1" GaugeMin="0" GaugeMax="255" ChartMin="0" ChartMax="255" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

Also engine coolant temp is MUT10 which should be 808863f on the USDM 5268 series, use the same calculation as above.

 

Is there any logging software which can log the knock, EGT and boost on X ? because evoscan 2.6 beta11 can't

 

Thanks SiC! Is this IAT (intake temperature at the MAF sensor) or IAT2 (intake manifold temperature)? I'll test it later tonight or tomorrow

Also, I'm trying to figure out how to get the MUT number for each parameter. Is this supposed to come from the service manual? For example, in the MUTIII table, it lists intake air temperature as item number 5. It does not list IAT2 in the MUT table, but does list both IAT and IAT2 in the OBD table as parameter 68. Sorry, I'm confused...

EDIT: I just found a post by mrfred where he lists these different addresses for IAT and IAT2 (which he labeled MAT = manifold air temperature):
coolant temp scaled: 0x80863E
IAT scaled: 0x808658
MAT scaled(?): 0x80865E

This IAT is the Manifold temp and my MUT is correct, I crossed them against temps taken by OBD2 loggers.

I used old Evo 9 MUT tables to get some address but they are not always correct on the X. The IAT & ECT both were different MUTs on the 9 vs X.
