Hi there! I need some help with any form of power sweep(Power sweep of Load Control). I have been tying to get a decent curve and numbers but dont seem to be able to get decent results. I am familiar with the PID concept and have read most of the online docs how this applies to the yourdyno software. As kP i have tried values from 0.10 until 1 with or without pI. Where pI variable from 0 until 1. 1 results in a stall though. so until 0.35 pI no stall's. With either the Power sweep or Load control it seems like the dyno is braking really late. my run's are from 1500 of 1750 until 4000 rpm. from what i can see in the logs its only breaking from about 2800 rpm which gives really strange curves(like art). I'll attach a set of run's to this post. The car i am running is one with some power and quite some torque. it seems that the "wait for x seconds" it not configured correctly. when i throttle the car at the "start run" rpm it does not seem to be breaking to hold the car at the "start run" rpm. i fly right through to around 3000 rpm. First runs just took shy of 2 seconds because of this. Maybe someone can help me set up this correctly? or how to approach this. Thanks in adcance! Kind regards. vincent-12-11-2019-001.csv

Im am watching the brake % while doing a run. Using the graph display type. I am seeing that the brake is doing somewhat of braking 5-10% an the start of the run and this increases to about 20-35% at the end of the run.

Regards!

Kind regards!

Also, make sure to download the Brake and gear ratio logging plugin. Then you can watch the Brake output of YourDyno. If the brake percentage increases quickly as you would expect, but the brake responds slowly, then something is wrong in the brake/power supply setup (outside of YourDyno).

Hi, what kind of brake do you have? If Eddy current, what kind of power supply?
