Welcome tuners!

I get many questions about YourDyno and particular setups, and I am happy to answer all of you. Since there are some questions that similar and people can learn by reading old replies, I ask you post your question here, and I will answer here.

Looking forward to hearing from you! PS: You can still ask using mail to jostein@yourdyno.com if you perfer.

Cheers,
Jostein

I have been working with Brian Lowery on setting up a land sea water brake and a your dyno. Please let us know the recomended wheel to energize the gear tooth hall effect pick-up for the RPM input, would it be a missing tooth sprocket or a aluminum wheel with a metal insert ,or a magnet insert ?

Hi Larry,

The RPM sensor senses any ferrous (iron based) material. You do not need to use a magnet. For Brake dynos, a simple bolt or two will do, and I don't recommend anything more fancy. Stay with max 2 pulses per revolution. The electronics is just counting pulses and dividing by the number of pluses entered in "Options" to calculate the RPM. The bolts need to come within 2mm proximity of the sensor. 

For Inertia dynos you need a very accurate trigger wheel, but no need for brake dynos.

Cheers,
Jostein

Hi Jostein! Let me start off by saying THANK YOU for making an affordable DIY dyno program! I was wondering if the gauges display live data even if you are not logging. Also, is there a way to rename the aux3 channel for display purposes?

Thanks in advance --- Jim

Hi, 

Thanks for your nice words. Indeed this world needed a nice, affordable dyno system!

Yes, the gauges display data all the time, also when you are not logging. And all Aux channels are fully programmable. You can call it whatever you like and the units are also programmable. They are also displayed all the time. If you right-click on the gauge you can choose digital or analog gauges. 

Cheers,
Jostein

I noticed on my setup, I had a hall sensor made by honeywell already installed on one of the shafts. Will your dyno be able to read the output of a hall sensor if I send the signal to the controller? Otherwise I can weld on a small piece of metal for the VR sensor included in the kit. I will be using the brake, but in case, I would like to have the option to use the inertia as well in case the brake over heats which is why I was thinking the hall sensor might be useful to incorporate. 

Thank you, 

Andrew

Hi Andrew,

YourDyno uses the Honeywell 1GT101DC, so if you have this sensor then for sure it will work. Many sensors are compatible, make sure it is of pull down type if you want to use something else. YourDyno also comes with a shielded cable. In some noisy conditions an unshielded cable does not work.

If you have a trigger wheel already, then for sure use it. A brake dyno works very well with a trigger wheel.

Hi Jostein , I can finally post , I would like to place a order for my Heenan & Froude GB4 hydraulic water brake engine dynamometer to convert from old analog gauges to PC based. 

Cya

PSJostein i will call you at the moment I'm having issue with my landline gone from old cable to NBN and they havent sorted out the issue yet. But we have email each other. I just wanted to make a few posts.

Hi! thank you for accepting my application

 

I want to build a test bench with double rollers for the front axle and single roller for the rear axle !! you can manage this system with the interface !! I would like both inertial and braked!

other project

is it possible to manage 4 electric brakes? 2 per control channel to measure a 4x4 with electric brakes on the wheels?

 

thank you

Sorry for missing this post!

Yes, indeed you can control a 4WD hub dyno. You need 2 YourDyno boxes. It gives 4 independent PID controllers for the brakes, 4 load cells and 4 RPM sensors.

Hi, that is a 1000Nm unit I believe. But you need the full spec. I did a quick search, but did not find it. Anyone? If not, ask on DYI Dyno on Facebook

I seem to have problems with the forum, it's really hard to access my profile, for now I just find my last post and click on profile there, but shouldn't there be a button in the upper corner or something where I can reach my profile, messages, etc. directly?
