Hi phill I did send you a message regarding your Clayton runing your dyno I am in leek staffs and would love to come and see your dyno working and thoughts on software etc do you use waterbrake 

I have exactly the same rollers and am looking to update but Carnt make my mind up weather to buy a your dyno kit our bite the bullet and sports divices kit 

any help be greatly appreciated cheers mave 

@phil177, just switch to imperial units and it will show mph and feet. 

@mave-race-engines, let me know if you have any questions on water brake support. We have done A LOT of water brake testing with YourDyno. There is even a special water brake mode, called load control. This mode is not using PID and is much better suited for water brakes than PID, in particular when you test engines with steep torque curve. 

I’ve tried changing it and makes no difference ? 
any ideas would be appreciated 

@phil177, I double checked it now and it works just fine. 

Remember to restart the program after switching units. You shall see the label "Speed (mph)" in the graph after the run, do you see that?

All sorted thanks for the help
