Virtual dyno

^^ thank you soo much should be great !

Question. When we use this what are the pids we need and if we have extras in it would it throw numbers off?

[underSRTarmor]

With a 2800 lbs car and me at 220. Using slicks it netted me 444 hp on a 4th gear pull stopping at 6000 rpm.

Accurate? I don't know. I don't care about hp.

RPM, MPH are all you need (and engine run time for accuracy). The engine run time should alleviate the extra PIDs throwing off the numbers problem.

One thing for guys doing logs to try now. Take a log with the engine run time PID along with all the other PIDs you normally use. Check what VD gives you, then remove the engine run time column from the CSV file and try again to see by how much the numbers are off.

According to your trap speed it's at least in the ballpark.

Looks a little high, But probably not to far off

Will be doing 2 different pulls tommorow one 22psi and a 25psi will post results tommorow. Should be more accurate since I got the right pids to log this time.

What's the difference in that and putting #'s from a Mustang and/or Dynojet? Absolutely nothing. I was doing this 4-5 years ago when I had my Evo (welcome to 2008 folks). There's already a huge # difference when comparing Mustang vs Dynojet, so that right there already tells you that there is no "set in stone" power numbers. Your hp/tq #'s are constantly changing with the weather and elevation, but I'm sure you already knew that, so in reality claiming any hp/tq is pointless. They are only reference #'s to yourself while in the process of tuning your car, to see the improvements you are making. I haven't gotten a chance to change my sig yet, but as you can see my VD #s are on there from my Evo. That car was remotely tuned because I didn't have the funds or the access to a dyno, so VD is all we had. It's a good tool to use. Once people stop worrying about whose horsepower is bigger...yeah right, that'll never happen, lol. It's their sig, so why should you care what it says?

[SRT4Delta46]

Did a 14psi pull today will post results soon

[underSRTarmor]

VD = lazy and cheap go to dyno or better yet track that hoe

I think ill post my v dyno numbers in my sig.

[SRT4Delta46]

^^do it lol. I'm going to dyno this spring to compare numbers that's the only reason I'm doing it to see the comparisons!!

[SRT4Delta46]

^^^ I don't have a track near me closest one is 150miles and for a mustang dyno closest is 100 miles away which I will be going to in spring.

[RMIKE88]

i tried it before it was way off lol i probably did something wrong tho

[Barn hill]

Im not very confident nor do I care very much for Mustang dyno accuracy. Those dynos just vary way too much to even try to get extremely accurate. Now the Dynojet numbers are close. Unless someone has a freak dyno that reads high or really low its pretty darn close.

LOL....SRS? Dynojets are the most reliable dynos in comparing #s from one station to another. They aren't manipulative, and so long as you arent in high elevation, they are accurate (dyno uncorrected in that instance). Mustang dynos? Take it to a trusted dyno shop, or ask for WCF to be OFF if you want real world numbers.

Yes it's been around for a while, and it was as controversial then as it is now.

Virtual dyno...exactly that. VIRTUAL. I can change my weight 100lb and itll change it 30hp. Wheel spin affects the #. Wavy roads affect the #. Slight downhill roads affect #s. Slight uphill roads affect #s. Not accounting for passengers, or random stuff in the car...affects #s.
My point? It is far more manipulative, and easier to do so, than an actual dyno, so credibility is iffy.

This!
I think its a great resource for using it for changes in tune and adding further mods.
I think the numbers that it came up with on stock turbo on pump and e85 are definitely in the ballpark for my given setup and trap speed. They definitely aren't numbers worth bragging about haha.
But if anything its free and it has its benefits.
