Good Day...
I have Yourdyno v5 and am installing on a Superflow 883 AWD chassis dyno. It has 2 Eddy's, 2 load cells and one RPM setup on rear axle, front and rear axles are linked.
I have a 25 year obsession of owning dynos for my small shop/hobby. From a large very cool custom Mustang dyno purchased in 2000 to a Land and Sea water break dyno that I owned for 15 years to my current Superflow. I am very confident in everything EXCEPT electronics wiring, so please bear with me on some of my questions re this topic....this may seem basic to you EE's but to the rest of us it can be confusing....
Install is going well I just have a few questions for the group.
1) My yourdyno software does not connect to the your dyno box. My computer sees it correctly in device manager but struggling to get connection. should this be automatic or do I need to initiate?
2) RPM sensor...Superflow uses a 2 wire sensor with wiring diagram labelling those wires as A/MAG and ground..how should I connect those 2 to box?
3) load cells..... I have two 5000# load cells Futek LSB400 with wiring diagram showing 4 wires SIG+, SIG-, EX+ EX- how should I connect these wires?
update:
I can now connect successfully!...an update to the software and a firmware upgrade and all is good.
number 2 above...anybody? do you want more info? this is seriously holding me up.
number 3 above....I found in the docs how to connect my load cell and I followed directions but it does not work correctly....I am getting a connection and data is being sent to yourdyno but the info is incorrect and resting it is showing it is raw loadcell data as 28,000 and 85% of max.....
let me know if more info is needed....these are the last 2 pieces to finish and i am complete.....
Hi @godspeed-dyno,
Glad you got it connected. YourDyno Standard v5 needs software version 3.3.x, as you figured out!
The load cell can be connected directly. Ex+ = 5V, EX- = 0V, SIG+ = Signal+, SIG- = Signal-. With no load on the load cell it should read about 0% +/- a couple of %. If not, something is wrong. It shall certainly not read 85% of max, that means either a mis-wiring or a bad load cell.
You cannot use the Superflow RPM sensor on the YourDyno Standard. This is a VR sensor, which does not generate a digital signal that the instrument needs.
There are two options:
1) Change to the YourDyno RPM sensor, or a similar hall effect sensor
2) Use a VR to Digital converter board. For example https://protunerz.com/products/axm-120-vr-converter-to-hall or https://shop.vemstuning.com/products/vr-to-hall-converter
