Right guys I have a Clayton water brake dyno running yourdyno setup
I’ve been using it inertia only am I right in think if I fit a load cell and connect it up to your dyno that it will still work with manual load instead of through the software and get an accurate reading ,
I intend to swap to an eddy brake when I have the time but for now wondered if this would work ok ? Any info much appreciated
Yes, sure. Configure it as a Brake dyno w/load cell, calibrate the load cell, and set the MOI (same number as when it is configured as Inertia). Then turn off the option "This dyno has an electronically controlled brake".
Then it is in manual mode, but all data recording is taking place.
Note that it is now a brake + inertia dyno.
Brilliant thanks

when I’ve fitted and calibrated it all I should get the same power readings no matter how much load I apply then shouldn’t I ?
say I do a run with no load on and the. Load it up it should give the same results ?
Yes. If you run with pure inertia, the MOI and the power of the engine sets the time the run takes between two RPMs. With a brake you can slow that run down, and the results shall be the same. You can also run from high to low RPMs if you want.
Note that the engine might behave slightly differently in slow and fast runs, in particularly turbo engines where the boost builds up. So a slower run will (correctly) give higher readings. There are other factors too that cause minor variations in actual power if you change the length of the run, so it will typically not be 100% the same, but it shall be very close!
