Poseidon Posted July 20, 2021 Report Share Posted July 20, 2021 translate from german to english Have been running an xtreme for a few months. Voting completed and going well. From time to time I had to adjust the idle. I noticed that from time to time the throttle valve regulates a bit back and forth, whereby the idle jumps from 700-1100rpm but not always and rather only when the TP main is below 5%. It runs flawlessly in a cold state up to 80 degrees. Even when driving, the flap swings up and down by a few percent every now and then but not always. I have already changed the flap. In the pictures you can see that the motor regulates DC% back and forth. All other values do not change. Pedal is also constant. It could be that the ecu has a defect in the regulation Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2021 Report Share Posted July 20, 2021 If the target is flat but the TP is oscillating then it would suggest the PID settings need further optimisation. Can you attach a copy of the tune and the log file. Quote Link to comment Share on other sites More sharing options...

Adamw Posted July 21, 2021 Report Share Posted July 21, 2021 Can you change Aux 9 to 500Hz and try the PID values from the M52 settings in the help. See if it behaves any better. Quote Link to comment Share on other sites More sharing options...
Poseidon Posted July 21, 2021 Author Report Share Posted July 21, 2021 okay, thanks, I'll try and get in touch Quote Link to comment Share on other sites More sharing options...
Poseidon Posted July 21, 2021 Author Report Share Posted July 21, 2021 I tested it today during the warm-up. Seems to have fixed the problem. Report to me again when I have the first test drive behind me Quote Link to comment Share on other sites More sharing options...
Poseidon Posted August 18, 2021 Author Report Share Posted August 18, 2021 it is a lot better, but there are still fluctuations from time to time. I don't know at which value I should start to see a change Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 18, 2021 Report Share Posted August 18, 2021 Attach the tune and a log. Quote Link to comment Share on other sites More sharing options...
