There's a new custom job called "RPM,MAF,etc.." that uses different job to get actual values from ecu than other custom jobs.I suspect this could have better resolution over values that ecu gives us. Would be interesting to know...

Thanks.

OK, I took some time today to test this. Traffic, cops and time kept from doing anything aggressive. Here's a screen shot showing time steps and the values from that custom job.

I wasn't able to find this value today in the time I had available... if someone who has the ability to create the Custom Jobs (last time I tried with my Win 8 machine it kept crashing) could put the exhaust pressure sensor values in with the boost values (set point, actual, temp, etc.) along with RPM and post a txt file so I could use it ... that'd be much appreciated.

I realize the above sounds like straight forward questions, but it depends upon what you are really looking for. Actual data from a sensor will be in electrical units. Some sensors are calibrated by the DDE. Generally speaking they will be related to AFR and emissions, as they can be 'double checked'. There is no obvious way to calibrate the manifold exhaust pressure sensor. That's why it would be checked for plausibility. I'm still figuring out the puzzle pieces and am looking at this from a different viewpoint - I want to know what the DDE is using for looking up ECU maps (and believe I may have figured that out). Even the same sensor can have different parameters associated with it depending upon the map being used.

Understand what you are looking for. Just can't answer right now and won't be able to until I can do testing on the car. But, an ass kicking winter and out of town travel is keeping me on the side lines. If you would be willing to do experiments, I'm willing to set them up in TestO. What I am suggesting is building TestO 'gauge sets' of like parameters, manipulating sensor output and logging the responses. Anyone interested?

So, you can use a custom job, but cannot create a custom job? Am I understanding that right?

Yes. I've been able to take your and pheno's "custom job" files and insert them into TestO and use them ... just can't create my own on the Windows 8 platform I'm using.

I'm willing to help. I've got some family obligations and then some business travel coming up, so I'm not sure how fast I'll be in responding. But I'll work it in as time allows.

Hmm, that really seems odd because I create them in a txt editor, outside of TestO. Can't understand why Windows 8 would have anything to do with it.
I think I should create a procedural tutorial to share with the group. Give me a day or 2.

quick note about custom jobs. I've changed the format in the latest version (13th Feb). It's in XML now. testo/config/customjobs.xml.

Reason is it gives much more flexibility for me as a developer in terms of saving/creating/editing jobs.DWR: hope you did not get too far with your tutorial.. I could even make it possible to save custom jobs to internet so they're available to anyone.. the latest version has already some functions to edit custom jobs but only edit for now (can I buy free time somewhere?)

Debug->Custom jobs: will read customjobs.xml and populate jobs into drop down boxes on the left. Select line and press 'del' key and it will remove the parameter. To add a parameter,press 'table' and from the window choose a parameter by double-clicking on it and it gets added into custom job. Now you can run the from 'start job'. Ok, very basic stuff but it's a start..

TDIwyse, the latest version should also contain crash dumper so you should find some .dmp files after testo has crashed on win8.1 which I can decode and find the callstack. Really looking forward to get this bug fixed on win8.1

I just completed it. But really like where you are going. THis is going to be a very useful tool. Cannot say thanks enough.

For those still on the old version, below is a short and sweet tutorial.

In some cases, a measured value is compared to a 'modeled' value to determine plausibility.

I have to retract my version of the 'ASMod' acronym. It appears to stand for 'Adaptive Spline Modelling of Observation Data'. My interpretation of it's uses seems to be confirmed.

Thanks. Will be interested in more of your findings when you post them.

Below is a chart showing the raw millivolt reading of the pre-turbines, exhaust manifold pressure sensor (lower trace) along with 5 other converted parameters. Slight differences between filtered and unfiltered responses, but overall quite close. The legend shows the 'job names' for each data set.

For those of you who are interested in turbine drive pressure, this manifold pressure minus the pressure before the DPF (Exh_pPFltUs) will get you there. Don't want to spoil any surprises but, Pheno is working on doing calculations within Testo, thereby creating custom parameters - anyone want to see a turbine drive pressure gauge and logging?!! Oh yeah.

Thanks, it looks like about 150-200ms per job with 5 data points. Not bad - to me it looks as fast with other job type (MESSWERTBLOCK_LESEN).

Testing .. and it looks promising. Feature list of the math library is quite extensive: http://muparser.beltoforion.de/mup_features.html

Here's some actual code adding several own, new results.

For example: MIKAS_RESULT's formula is: STATUS_INT_WERT*7

STATUS_INT_WERT is a ediabas job result.

    eval.addExpression(j, "MIKAS_RESULT","STATUS_INT_WERT*7");
    eval.addExpression(j, "MIKAS_RESULT2","sin(STATUS_INT_WERT)*5");
    eval.addExpression(j, "MIKAS_RESULT3","log(STATUS_INT_WERT)");
    eval.addExpression(j, "MIKAS_RESULT4","STATUS_INT_WERT");

produces:



It takes additonal ~0.5ms per job to add these custom expressions on my 4 year old 4-core laptop. I think that's feasible :-)

[TDIwyse]

This is all really neat. Thanks.

So is the Exh_pPFltUs on our US cars the "differential pressure" sensor? Curious as to how the DDE would get the absolute pressure before the dpf from the "differential pressure" (think the European version has a different pressure sensor setup than we do).

Did you log the STAT_AsMod_pTrbnUs_WERT to see how it compares to these other drive pressure jobs?

Looks like latest TestO (13th February) is working with Win8.1 64bit.

Good catch, the parameter I put in parenthesis is a big fat zero for our cars. Sorry about that. There is another parameter for the pressure before the DPF that does have varying response - but don't ask me where it comes from or whether it is valid. I haven't a clue.
Once I found parameters that closely followed the mV sensor signal, I moved on to other things. Until I get a better understanding of the AsMods, I'll be staying away from them, for datalogging.
Really trying to devise a method to use unused sensor inputs to measure things we cannot currently measure, via the DDE. Things like temperature before the turbos, pressure after the turbo, etc.

I like the new version

This was run with 30 labels on a N47T - sampling times vary, but fast enough.

Lol

[TDIwyse]

OK, I had a little time and got the new version downloaded and installed. It's hooking up to the car correctly, so that's good. Haven't yet tried to create my own custom jobs on Win 8 with the new program. Did do some brief looking for the drive pressure jobs, but didn't see them ... DWR, where did you find them?
