Hi,
When i try to run a power sweep, the brake goes to 100% when reaching the start rpm.
Then the engine rpm drops and the power run begins. The target rpm goes to 6000 rpm but i can't get higher than 3000 rpm on the engine.
In manual mode when you reach the target rpm the brake keeps on increasing till engine speeds drops.
What could be wrong?
Config file
There are a few things that can be wrong. One idea is that you have set both RPM1 and RPM2, but only use RPM1. Engine RPM is then Gear ratio * (RPM1 + RPM2) / 2. If this is the case, then as soon as you reach the start RPM, the brake controller sees that RPM1 is twice the target (since RPM2 is 0) so the brake goes to 100% and you will only reach half the max RPM.
If you use 2 RPM channels, but only have 1 brake RPM, then set RPM2 to Other RPM.
That's my best guess. If this is not the case, then send me the saved config file (backup options to file) and the csv file and I can take a look.
I have it configured like this
@loic yes, this does not work. It now thinks you have two load cells (two brakes). Each will have an individual PID controller. Configure RPM2 as Other RPM instead of Load cell 2 RPM.
Make sure you set the gear ratio again after this change.
Thank you for the fast reply, i will have a try with the different settings.
Problem is resolved with the new settings. Thank you for the fast reply!
