Virtual Dyno

[bbarnhill]

Here is the release of the full version of the standalone HP/TQ graphing application that reads Evoscan logs, and doesnt require Excel or copy and pasting your data.

The interface is pretty self explanatory. You can drag your CSV files to the panel on the left, then enter the appropriate data in the box that appears and your graph should appear. There are several graph options and those can be accessed from the menu at the top. There are only a few cars in the data file as of the initial release but as soon as a few more people test it and get me data on other vehicles I will add more.

It's a free program...and one that is very cool and easy to use. Hopefully we can get a few more folks testing it out and reporting results!

[silvapain]

If you want to use this with a COBB AccessPORT datalog, these are the minimum fields to log:

1. time (always logged)
2. RPM
3. Accel. Pedal Pos. OR Throttle Position

Optionally, you can display AFR and boost by logging these values:

4. Actual AFR
5. Boost

...and then setting up the options table thus:

[bbarnhill]

Silvapain: if you have a log that has those columns in it send it to me so I can add those column names to the default list then you dont have to set those in the options window.

Send them to bradbarnhill at hotmail com

Thanks,

I didn't want to post this earlier without verifying, but I just checked it. You need to log Throttle Position, not Acc Pedal Position.

Brad, something that would be nice to have is a mechanism to average runs. I typically grab three data logs on a given tune to find trends. This would be especially helpful since we are subject to variances in the road. I would love to be able to select which runs to average - IE data logs 1,3,6 are one average, while 2,4,5 are a second average. But where we could select any number and position of data logs to average. Just an idea!!

[wolly6973]

Just played around with it some. Pretty easy!

240 hp and 260 ft lbs.

I hope that's not right!

[WorstEpEver]

Heres my logs. 3 runs total, same road, 3rd gear pull.

I never dynoed my car, but numbers seem to be right at what I should be expecting with my mods.

BTW, thanks Brad. Very cool program. The results look pretty consistent which should help me track changed made to my map. Nice also to see a visual representation of logs. Looking at excel sheets for a long time makes my eyes hurt =/

there's already a thread in this same section of the forum about your product though...

[AZSPEED3]

Been using it for a week now. So far have gotten repeated results. On a stage 1+sf 91 oct bt map
Have been getting around 240-250hp 280-285tq. not sure on how acurate. Really looking at it show
increase in hp/tq with each mod, before and after

Rich: the thread was created by someone else so I cant update the images when the new version comes out. Thats the sole purpose of the new thread.

AZSPEED3: holy crap ... its how a dyno was meant to be used ... lots of people dont know that Nice to see someone that does use it for more than peak numbers.

I was able to get the graph to work correctly even after deleting all columns in the .csv file except time, RPM, and accel. pedal pos. I did not have throttle position in the file.

Maybe it will work with either or?

I will post a log for you tonight Brad.

It doesn't matter which you log as long as I have the definition in the columnnames.xml file. I just use it to tell when you go WOT, to trim the rest of the garbage out of the file.

How bout integrating say from 3k-6k. That way we get area under the curve for comparison. Might be a cool feature too.




By the way if you're like me with a dashhawk you'll need to export into excel and then you'll need to divide time into how many cell lengths there are. And then make sure your colums are neat and tidy like below and then copy and paste into a text file.

Time RPM AFR TPS Boost
0.90 3293.75 12.16 100.00 19.14
1.05 3321.50 12.09 100.00 18.70
1.20 3387.50 12.11 100.00 17.69
1.35 3429.25 11.86 100.00 18.13
1.51 3509.50 11.85 100.00 17.98
1.66 3598.75 11.60 100.00 17.98
1.81 3674.75 11.58 100.00 18.13
1.96 3712.75 11.47 100.00 17.83
2.11 3820.75 11.49 100.00 18.13
2.26 3882.00 11.46 100.00 18.13
2.41 3945.25 11.46 100.00 18.13
2.56 4010.75 11.47 100.00 17.69
2.71 4069.50 11.49 100.00 17.40
2.86 4141.25 11.44 100.00 17.40
3.01 4225.25 11.36 100.00 17.25
3.16 4278.50 11.27 100.00 17.11
3.31 4352.75 11.41 100.00 16.82
3.46 4419.50 11.29 100.00 16.53

And you'll see it works just like the cobb guys.

[bbarnhill]

send me an export file unmodified from dashhawk and Ill try to make it work. If I can ... it has to be in CSV or TXT format. (Comma or tab-delimited)

Also you can limit it from 3000 - 6000 if you want with the slider bar at the bottom of each run in the left pane.

[SLOWHATCH]

JW if any of you guys with an AP have used the dynamometer option to figure HP and TQ levels? Wouldn't that be easier, or is this new method more accurate?

[AZSPEED3]

The ap dyno is very inaccurate. The virtal dyno is more accurate in helping compare before
And after on new mods. Give it a try, has worked great for me so far.

[bbarnhill]

Just curious but is the dynometer in the software on the computer for the Accessport or in the device? Just curious as I sent cobb a copy of my software back in the day to evaluate to buy it, and never heard from them. I want to make sure they arent robbing me.

The dynometer is in the accessport. You do a WOT pull in 3 or 4 gear and the ap gives
out a reading of hp/tq by the datalog. It does not show an actual dyno plot on the ap or ap manager software for the computer just numbers on the ap screen. Usual not that accurate for back to back WOT pulls.

[bbarnhill]

... they should have bought my software from me back in the day. I would have continued to develop it for them ... just sad ... they missed a HELL of a deal.

[WorstEpEver]

Couple more runs. Looks like tweaking my tune did me good =)

[silvapain]

Here's a COBB datalog with Actual AFR and Boost included Brad.

[bbarnhill]

I went ahead and added this to the definition file this morning ... Ill get it out with the next update asap. Give me a day or so.

[Caldazar]

Thanx for putting this out there Brad! Very cool!

now, can you put up a step by step for us d'oh heads? Just to make it easier for the first time?

[AZSPEED3]

It's pretty straight forward. Start up the virtual dyno and upload a datalog you have saved to your AP or whatever you datalog with. Then select the car and make. It will then plot out a dyno chart based on your datalog.

[Caldazar]

cool, thanx !

so there is no "setting it up" etc? I read up in the beginning of the thread that it had to be setup for our cars with only 3 things checked?

[AZSPEED3]

Nope, its all ready setup. I think what your talking about is what parameters need to be datalogged but I just use the set parameters that the AP does on it's datalogs and works great for me. You can email Brad for more info if needed, check his sig for email.
Hope that helps clarify.

You just have to make sure that your AP is set to log RPM and TPS. Then just export your logs and drag and drop them on virtual dyno ... easy.

Hey Brad...here's your program, being put to good use:

There is no "setting up" per say. You just have to make sure you log RPM and TPS in your data logger. Other than that ... there is no setting up. Also if you would like boost or AFR to show up just record those too.
Hope that helps.

I posted a comment in your thread. Nice graph

[Realgib3]

Soooo the only thing that we need to finish this off is timing. Being able to see timing advance along with the boost and afr would be a HUGE help for tuning

[bbarnhill]

Im working on a solution for this. Dont ruin all the surprises for future development.

[bbarnhill]

1.1.2 has been released ... enjoy

[Caldazar]

changelog for the new version?

[bbarnhill]

change log? Do you mean the release notes?

Its available at BradBarnhill.com ... click on Release Notes. If that is not what you are looking for please explain a little better and Ill try to help ya.

[Caldazar]

no thats it

thanx

[Burdoror]

Will Virtual Dyno support Auterra dash dyno in near future?

[bbarnhill]

do ya have several example logs with RPM, TPS, BOOST, and AFR recorded? Or atleast RPM and TPS? Ill PM you my email address so you can send them to me if you have a few. They need to be in CSV or TXT format.

Thanks.

[Burdoror]

HI. I'll prepare something

[dooderek]

this app is da shizzznit, also be sure to edit your runs to delete all the "decel" part of the log so it dont throw the numbers off
