Virtual Dyno - Standalone Software
Finally tried the latest release... .the color scheme now is a lot easier to use and makes my argument about same line type not that important. I did notice that torque numbers seem really low. I tuned a 35r yesterday that was around mid 400s at 27 psi, but torque was around 275. That has to be an error. Curious as to maybe me doing something wrong ?

Ok good deal. May be able to auto figure the values form the runs but maybe not ... should be interesting to get data from ya to prove either way. Its nice to have people willing to provide data. Im all about adding anything I can to it. I may have the ability in the future to log live straight from the OP2 cable if I can figure that out. If anyone knows the communication information, Id be curious how to setup a port to communicate with the thing. Id LOVE to get a test bench setup at home too but that may be just dreaming. Here is one for providing data. 
I may also in a future release adjust the TPS trimming to figure the first WOT section to be the run so if the person shifts gears the run ends, may make this an option. It causes weird loopbacks because it expects one gear throughout the run, and there is no way to detect the gear unless maybe if MPH is recorded.
Not going to get into that right now. I am going to also with v5 support every Evo that I could find information on. Hopefully going to put that information in the XML file tonight or tomorrow. Exciting things coming in V5. We will see if everyone likes it. I still have to let it go to beta after the profiles are done so its a few days out yet. Just be patient as it will be worth the wait, I suspect.

did you get my email with the dsm link files?

I just went over the temp and baro numbers for the logs from the 24th. These are the results ...
EDIT :: I'll add that the resolution on the temp log may be a limiting factor ... it seems to jump in near 2ºF increments. Probably not a big deal for quick comparisons, but worth note.
Code:
Run one: Baro Actual 99.07 Logged Start 3000 5000 7000 99.47 98.98 96.53 96.04 Temp Actual 77.2º Logged Start 3000 5000 7000 82.4º 80.6º 77º 77º Run two: Baro Actual 99.07 Logged Start 3000 5000 7000 99.47 98.98 97.02 96.04 Temp Actual 77.2º Logged Start 3000 5000 7000 82.4º 80.6º 77º 77º Run three (4th): Baro Actual 99.07 Logged Start 3000 5000 7000 98.98 XX 97.02 XX Temp Actual 77.0º Logged Start 3000 5000 7000 78.8º XX 75.2º XX

Out of curiosity, what intake are you running and what boost were you running/turbo?
I'm just curious, because that pressure drop is somewhere in between what I have seen on my own car from the stock box to the ebay bolt on open air filter.

K&N filter and adapter (not the Typhoon), MPFab intake box, stock intake pipe. 28.5 psi tapering to around 21 psi on E85 and stock IX turbo.

mate temp and baro will change depending on mods on the car and the ambiant temp. i have seen differences of 5+ *C pull to pull from ambiant temp.
similarly cars not running maf's will not have the baro value. if u do have baro at vacume/idle the baro pressure is closest to ambiant..... actually i would assume it would be different due to the air flow. so baro pressure when the car starts is most probably closest to real baro.

You have a good point about an SD setup. Baro would not be there and AIT temps will be at the manifold, so will not be anywhere near ambient.
However, if you go back to my original post about this, you'll see that my suggestion was to have the option to use the logged value or input them manually, preferably with the default being to pull from the log. This way SD (or anyone with the preference) guys can still input the data manually as it is now, and if you have a MAF and want to use the logged data by default it saves a few steps in the process. If you don't want to use the logged data, just don't log it and the values would default to 0 or whatever I guess ...

ok, i must have missed that part. also i think even at 7000rpm the difference could be different due to heat soak, and pod filter arangement. i recon try it with a pod filter without any heatshield and it will be different to temp with the stock airbox.
but good option for many cars as it will save manually entering values.

TWO long days of coding finished. I wasted part of the day today trying to parallelize the code so it would be faster on multicore machines. I ran some tests afterwards and it just wasnt faster. So I ripped all that code out but I learned how to parallelize my code now. I am reworking the column name files so its structured a little different. This shouldnt delay me getting it to beta tomorrow sometime.
Look out betas ... its coming to ya soon. People this is another massive upgrade so be aware that working with the betas is going to take a few days to make sure things are running smoothly. Thanks for your patience.

If you want some data, search for a review of the ebay filter by me maybe 3 years ago or so. I have baro, temp, and air density data in there and discuss which was better overall.
Here you go, saved you a little time.
