@mikecarr4, I wonder if the save issue can be a permission thing. Is your user admin on the PC? I have tried to reproduce it unsuccessfully. 

Also, the torque arm length doesnt seem to save occasionally in version 75. I have gone back to 59 and all saved now. This is probably not something people change very often.

See video.

Have been getting this occasional error message through with the latest version has anyone else had this?

@admin

Thanks for looking into this, I will do my best to test this today with the changes you've suggested.

Hello, yes that will work. 

Hello. Latest firmware will work with old software 3.2.59 ?

Regards

Guys,

There was a bug in the latest firmware 1.24 which would make RPM1 hang up in some special situations, as was reported here (thanks!). 

Please upgrade to Software version 3.2.76, then click Upgrade firmware. 

Happy tuning!

@admin, I have created a good log file now.

Attached .jpeg here and I am sending the raw on e-mail.

Guys, I have kept it running now for hours, I am not able to reproduce it. Can you send a raw log file with the issue to jostein@yourdyno.com please? Record when both hubs/rollers are spinning or at least when RPM1 is spinning. @aslot it would be good if you could capture the moment it stops reading RPM1. 

@aslot  Hello,For what its worth I too am having issues with my RPM1 disappearing after a short time. I have only one RPM input, a GT101 sensor (engine dyno). I too have to do more testing but I do have a good RPM signal at the Your Dyno plug when operating correctly and also after the tacho stops. I had no RPM issues prior to this. I too updated to the latest version before this happened. All other gauges keep working without fault when the RPM stops. It does appear to be a software or box issue.

I have now done some more testing.

At first start(system and PC-boot) I have RPM1 reading, after around 30s with spinning hubs the reading stops and only shows 0rpm.

If I switch the RPM1 and RPM2 connectors at the box I still only have RPM2 reading.

If I disconnect and connect the USB to the box I get RPM1 reading for around 30s again same as at first start.

I have tried to change all the filter settings but nothing works.

@admin, Roller1 RPM gauge shows 0RPM all the time, Roller2 RPM gauge shows the correct RPM. The total RPM(Engine RPM gauge) shows around half the real engine RPM.

The sensors are working and the gear ratio is correct, if I switch back to 3.2.59 I have RPM reading on RPM1 and RPM2 gauge and the correct Engine RPM.

@aslot, I have tested this again now on v3.2.75, and it works correctly with all combinations I tested. So maybe I misunderstand you? 

When you say to get RPM1 to work, what do you mean exactly? If you enable the Roller1 RPM gauge, what does it show?

@aslot, check Advanced Gear ratio setup. You may accidentally have turned on the Primary driven wheels option. This option is used when you have a 4WD roller setup and want only one set of wheels to calculate the engine RPM (i.e. for cars that are primarily front of rear drive, 4WD "light")

The primary driven wheels option is off.

And yes, the Brake and Gear ratio plugin makes all Roller/Hub RPMs available to both log and show as gauges. You may need to download the newest version.
