Virtual Dyno

**bbarnhill** · #1: 07-07-2011, 03:02 PM

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.

Feel free to let me know what you think and suggestions on improvements. I know I am opening myself up to a lot of criticism but thats the only way to make this app better.

Thanks to all of you that have helped support this application through development and to all of those who have waited patiently for it. {thumbup}

Many thanks to some who have contributed over and over to its development:
Mellon Racing
Boosted Tuning

Also if you would like to donate to the project feel free. I dont require payment as I rely on donations to keep the project alive. If you are a tuner please consider who keeps you in business and who develops software to support you. Donate a little per tune to your open source community that supports you so well.

Excellent job! I appreciate the work you do to make log plotting possible, aside from airboy. Since this is a legacy forum, is there a way you can add the 5EAT in with the rest of them. I know since the TC delayed lockup causes weird numbers...we still use the program for pre/post tunes and modifications....

5speed automatic Sportshift
1st 3.540
2nd 2.264
3rd 1.471
4th 1.0
5th 0.834
final reduction 3.083

that's for the 2008 USDM LGT 5EAT

Here you go:

Very cool, thanks!!

Just added that vehicle ... should be out in a few minutes. Just start your app up and it should update itself.

**bmx045** · #5: 07-10-2011, 06:01 PM

Thanks! just to let you know, when I opened virtualdyno up it checked for definitions and all but it did not add the car. I uninstalled and reinstalled the software and now it's there.

**bbarnhill** · #6: 07-10-2011, 06:07 PM

Weird ... updating of the car definitions works on all the machines Ive tested it on (moms XP machine, my win 7 desktop and laptop, the wifes win 7 laptop, dads windows vista machine ... and other betas). Again ... weird ... maybe it had a hiccup connecting to the server or something to download it ... *shrug*.

**bmx045** · #7: 07-10-2011, 06:11 PM

Potentially, I was waiting for it to say 1 new definition available, or something. I closed and reopened the prog a couple times and it still didn't catch. Who knows. No if I could only find my logs.

**bbarnhill** · #8: 07-10-2011, 07:53 PM

I may add something that shows in the program for a little longer when columns were updated. ( I cant tell how many columns were update just because of the way it is setup, but I can tell that a new version of the file was downloaded.

Thanks for the fun!

We need an 2005-2009 GT Auto option! For this graph I used the '08-09 auto GT option although I have an '05. Not sure how much I like this graph LOL.

**bmx045** · #**11:** 07-12-2011, 08:03 AM

Blongo, that's how AT curves look. You read the highest point after the torque converter has locked up- even then, a real dyno will read different peak numbers after tc lockup. Only use this for before/after mods and stages. I also noticed you didn't put an occupant weight number in, so your total weight is more than 3330 (which will incr your hp/tq #'s). Also correct for temperature.

I just used this (being an 07) i went with the 08+ selection. Not sure if it is correct, but I liked it! lol Keeps my dreams alive for now.

YourConfused, sorry to shoot your dreams down but I doubt we have anywhere close to 500lbft. of torque. A new graph with updated data -

Pretty neat. Here is the Virtual Dyno using the data log from the real dyno.

I like the simulated dyno better than the real one

Wow! you must have a spec B!
