@admin “the setup ended prematurely due to an error” … or something similar.

 

the only option is to exit the setup, then Yourdyno can be started as before. Last time I lost all settings…

Hi 

I like the focus on the enertia calculation👍

May i ask if there is a function to implent the loss from brake fan/static losses on the way?

@thdyno, yes this is planned. First though comes live graphs in the main window so you can have the gauges and the graphs update at the same time. This is next up.

@matteozanusso, send the exact error message to me at jostein@yourdyno.com if it happens again. Exit YourDyno before upgrading.

Can you explain this a bit more? I want to understand what this means to know if it's something I will have to watch out for once my dyno is up and running.

Hi.

The issue is that the losses in a eddy current brake fan isnt linear. It increases quite alot when the brake is at higher rpm

Its no problem when the losses is measured during coast down. In that way the increasing loss is captured and calculated in the engine hp graph.

If you want to measure the wheel hp it will give you problems because the loss isnt linear. In that way the reading will be quite different depending on brake rpm

Hope its understandable 

im not an expert 🙂

That makes sense. Thank you. For me currently that won't be an issue, since there is a water brake fitted, however I am keeping my eye out for an Eddy current retarder to maybe swap in. If I do, I'll keep this effect in mind.

Just started using the latest from .129, I see that it picks my system language for column description under the main screen and it doesn't change even choosing another language from the option.

@dev, on the total correction formula. 

The confusion is on the power correction factor. The reason is that the correction is seen from the engine i.e. you lose x %, so Wheel power = Engine power * (1 - x%). To calculate the Engine power the correction factor becomes Engine power = wheel power * 1 / (1 - x%).

Tuners,

A very minor bug fix, in that the OBD2 RPM had dropped out of the Engine RPM source in Gear Ratio setup. Fixed here: 

YourDynoInstaller_3.2.137

Cheers,

@breastfed, I have not seen that problem. Maybe a reboot does the trick? Or try to uninstall the previous version first.

@six_shooter, 137 is the latest, I fixed the auto-update that showed 138 is the latest.
