Virtual Dyno - Standalone Log Analyzer

[bbarnhill]

wow ... all good suggestions. Ill look into all these. Some are feasible and some not ... Ill surprise you guys if the gf gives me time to work on it.

^you should consider charging for this and start a fund for Coach purses and pedicure gift cards. I did my part already hitting the donate button a year ago or so but I am sure the time and energy you have invested on this great program would only be paid back if you started charging for it, rather than relying on sporadic donations.

[bbarnhill]

yeah the donations are kinda sporadic at best (I definitely am not getting rich, I havent made enough to buy anything really, Im saving for a really good bluetooth obd reader so I can work on a wireless logger). I think it would be hard for me to start charging for it now unless I stopped updates and just came out with a paid version which might trim out some of the newbs that I waste 90% of my time explaining what a dyno run is, and what TPS is and the like

maybe more encouragement from those that have donated will get others to donate. In all honesty I get about 25$ a month from donations. Kinda poor considering how much its used but oh well I released it for free. It just makes me think real hard about releasing my logger for free or building in logging to VD

Added the ability to toggle the HP and TQ lines and moved the show data points and toggle legend to a settings dropdown on that button bar on the graph. The toggle HP and TQ will not persist when the app is shutdown. It defaults to drawing them when the app starts up.

I have these in 1.2.0 Beta 2 but I havent released that yet ... but I will in a few minutes.

keep getting this error after selecting a profile then trying to upload a log into vd....

My opinion is, work on a paid version.

I just tried this yesterday, after all this time. Even with first-time jitters and errors I learned something I wanted to know. It was important enough and clear enough to cause me to make changes in my tune.

I plan on using this more, regularly in fact. Ever since DDD became cumbersome I've missed its input to my looking inside my tunes. Virtual Dyno promises that input and more.

Make a product polished enough and I will pay for it.

Can you send me your profile.xml? Click Help->Open Data Folder and it will take you right to it. bradbarnhill at hotmail

Its getting polished. I just have to add the custom car feature then its pretty much feature complete. Other than run averaging which is flare and isnt really going to add much to the program I dont know what else to add. My logger I was gonna merge in isnt fast enough ... I have a 200ms delay somewhere in the requesting of the pids.

[V8 GTFO Lesbic WGN]

^agree, how more polished can it get? Obviously the poster has not used the other alternative....

Thanks Brad for adding the TQ/HP toggle function, BTW the 1.20.0 is not live yet.

True, inexperience with this, but very impressed as is. My comment reflected what I thought the OP was saying. My offer to pay stands.

My one session amazed me, frankly. But I have yet to actualize a couple preferences relative to log manipulation. Many of my logs are made during a long ride, in which only scattered, short, events are useful in VD. Maneuvering to and bracketing those WOT events inside a longer log escaped me. For now, knowing I'll be using VD, I will start/stop logging for WOT events... which is how I always did it before. But I've found a lot of value in long logs, and intend to continue them, but with this tool it is no problem to modify things to include capturing WOT events individually again.

Very true 1.2.0 isnt live yet but its coming ... I dont plan on making it take as long as 1.1.9 did.

Just open the file with Excel and trim it down to the part you want to plot.

That is next. My abilities with Excel are less than most probably have, learned specifically for tuning. Each time I have to do something new I learn... this time I learned I should try that on a copy of a log. I lost the only good log of the day when I tried this... it replaced my log with unrecognizable gibberish.

Today I will attempt this again. Even with the "gibberish" VD was able to give me useful information. It promises to be an exciting tool.

Was anything changed on the latest version. Even on dyno jet settings it reads a Tad lower than airboy dyno. It was reading about 15% higher than airboy on same logs. It auto updated last week and now reads differently than before. Guess ill have to switch back to airboy cause the higher numbers make my balls feel bigger lol.

The smoothing numbers changed. Maybe you are still using a higher number and it's over-smoothing the plot? If you were on smoothing of 6, and then switch to smoothing of 4 on the new version, then you get the same plot with the same numbers as the old version.

But if you just want high numbers, change the correction factor to 2.0

[bbarnhill]

Change to a CF of 0 and get a wavy graph but a way higher number.

The calculations portion of the code hasnt changed since 1.0.1 and it has unit tests wrapped around it to make sure it doesnt change. If it changes it will fail the unit tests and let me know that its getting a result that is unexpected. I check it to the 15th decimal place for any variation. Ive got tests wrapped around the HP calculation, the TQ calc, the tire size calculator, the drag HP factor ... etc etc. So Ill know when something changes I had to do that when people were saying things were changing a few versions ago. I had to give myself the peace of mind to know they were not changing. The smoothing factor did change last version and xluben is almost correct. Take the number in the smoothing and multiple by 2 to get the old smoothing number. So the new 4 is the old 8. I corrected this to be more in line with what you see when using a DynoJet.

Ill be happy to answer any questions if anyone has any related to the calculations (other than just posting the calculation up here as thats the only thing I keep secret but its really not that secret as its just physics).

I thought it was 2x, but it doesn't appear to be that way. On 1.1.8 I used a smoothing of 6 and got 463WHP/468WTQ. On 1.1.9 if I use a smoothing of 4 I get the exact same HP and TQ values.

[V8 GTFO Lesbic WGN]

is 1.2 ready to go? can't wait for the toggle on/off HP/TQ option.

1.1.8's smoothing was actually X2. So 6 was really 12.

On 1.1.9, smoothing is X3, so 4 is actually 12.

I've been testing the 1.2 Beta for a while. It seems like it almost ready to go, but then again, I dont know what Brad wants to add/fix.

The toggle HP/TQ on/off option works perfectly. You'll like it.

Also, me and another tuner that use VD a lot, made a guide to help everyone use VD correctly.

I've come across that before. I like the beginning of that guide, but I don't think that checking the logs with smoothing set to 0 works well with RomRaider. It is good to make sure you don't have spikes over 1000WHP, but it's frequent to see them at 150% of the properly smoothed numbers, and they're still "good" logs, IMO. The check of smoothing of 1 vs smoothing of max (6) seems to work well. On my logs the difference is usually only 2-3% (10-20WHP) between smoothing of 1 and 6.

Yeah. That guide is more based on EvoScan logs, but still has some good tips/ideas.

[bbarnhill]

Smoothing 0 is never meant to graph for anything other than to diagnose and see large spikes. You will be able to see them in the raw unsmoothed format. I think that feature is worth while leaving in there.

Oh and I was wrong (even though I wrote it) that the smoothing is now x3 as Evo_Kid said. I was trying to answer forum posts and get ready for work

Smoothing 0 is an excellent tuning tool, IMHO. It has become an important aspect of VD for me, for diagnoseing my logs just as you say.

Thank you for an excellent program... that apparently gets updated automatically.
