ITT: We discuss Virtual Dyno settings
6 Attachment(s)
So I'm trying to get virtual dyno going. And to get good baseline settings I'm using actual dyno runs to compare to the logs.
The issue is, they aren't even close to accurate. Dyno printout https://www.miataturbo.net/attachmen...ine=1452624689 Virtual Dyno, weights adjusted to get as close as I can to the right numbers. https://www.miataturbo.net/attachmen...ine=1452624689 What gives? (Logs attached) |
What inputs does the virtual DYNO use for its calculations?
|
Megasquirt log

Did you expect it to be accurate? AFAIK Virtual Dyno should only be used to compare against Virtual Dyno. AKA consistency rather than accuracy.
|
I expected it to be closer than this, at least the way its used around here.
|
I've compared it to NUMEROUS actual dynojets and it's always really really close. like 2-4hp close
and the curves are also really close. like almost identical. you can check many other forums and see that there's threads like this and all of them match up. so you're doing something wrong |
do you have a 6sp in the car?
why are both car weights you're using so completely off the wall? don't you have a 3.9 torsen? |

4.1 at time of dyno weights are to try and get it to even be close. without weird weights its at like 280hp STAHP NINJA EDITING |
Why is your car weight set to 1300 lbs?

so they were that at time of dyno and not that now?
welp..... |
Logs are from the dyno runs.
|
Yikes.
|
that's weird. I'm too busy and lazy to troubleshoot, will check back when I'z bored
*edit: BUT WAIT |
you can't use the logs from the dyno brah
|
logs are attached to the first post for your pleasure.
|
motherfucker, thats probably why.
plz delete thread out of embarassment. |
cause the VD software calculates drag/resistance, which you don't have on a dyno
|
it calculates frontal area against wind and some other sort of mumbo jumbo
