Good job! Did you find a good repeatability of the tests? In my setup repeatability now it isn't good, between two tests I see 0.6hp of difference. To...

I think that noise is not caused by oil hoses. Sometimes the torque jump between 0.01 and 0.03Nm that is a good result, but usually, with power supply...

Ok, but is necessary ground yourdyno box? If is necessary, yourdyno box must be connect by wire at mains earth? Because I still have noise on load ce...

Ok but I have still noise on load cell and thermocouple. Load cell after calibration goes always up and down between - 0.30 and - 0.10Nm.

I see that also in your setup when you grounded the box the noise increases, Is correct ? What kind of capacitor do you have installed?

I have also see that if a grounded the box, the noise on the load cell is higher. With grounded box is about 0.3/.4nm, without grounded 0.05/0.15nm. I...

Ok I connected V- from fan and stepper motor power supplies with yourdyno box. I see that after grounded all togheter i must reset load cell zero. Its...

The ground of stepper driver is the dc- wire correct? So its the V- of all other power supplies correct? Sorry but Im not very strong with electronic ...

Hi, how did you do to ground the blu box?

Now after some experiment, with the help of Jostein I solved my problem, was a brake setup issue.

I have ask to Jostein if he can implement this function (to keep the temperature at preset value by check fan velocity or fan activation) on yourdyno ...

How do you control the fan?

Very nice setup! At the moment what kind of hydraulic valve are you using?What pid setup are you using?

I killer vibration with engine plate with antischock, the works good. Post here the photo of your dyno. IMG_20181008_185717.jpg

Hi, I have start yesteeday the test with my dyno with manual brake control. I use 70cc gear pump, and ndv 3/4 flow valve. I suggest you to use bigger ...
