I am in the process of setting up my dyno - when I look at a run without any filters applied, I am seeing a lot of noise on the load cell data to the point that when I apply the filters I am shocked it can make any sense of the data. I have made some changes to the load cell mounting method and this has improved the data, however, I do not know what good looks like for unfiltered load cell data - please can somebody share a run with unfiltered data to help me understand if I actually have a problem or if this is typical? Thanks.
Hi, the noise varies quite a bit from one dyno to the next. Low inertia, direct connected, single cylinder typically gives a lot of noise while high inertia soft coupled are smooth.
Results should look good with filtering between 3 and 6. 3 is default, and probably 80% of the setups are ok at 3. Post your unfiltered graph and describe the dyno system and I can evaluate.
Hi Jostein, thanks for the reply - I can't see an option to post any images, do I need to reach a minimum number of posts before this option is available? Thanks.
This is an example of the unfiltered data, please let me know what you think. Thanks.
It is quite high but not out of the ordinary. What type of dyno and how much inertia is it? It is quite easy to filter out, maybe except around 3000 RPM.
