Vaughan Posted August 24, 2023 Report Share Posted August 24, 2023 Attach a copy of your tune and a PC log of how your E-Throttle is currently working Quote Link to comment Share on other sites More sharing options...
Spyrosgeo Posted August 25, 2023 Author Report Share Posted August 25, 2023 Take a look at my setup and pc log. As you can see when the e-throttle is on target at 1.6% suddendly drops at 0% and goes back to 1.6%. Also the e-throttle isn't stable under some conditions when it goes up to certain rpm. Here is the pc log: https://www.mediafire.com/file/2i3g44wbptbqagd/PC_Datalog_-_2023-08-25_9%3B10%3B34_pm.llgx/file Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 26, 2023 Report Share Posted August 26, 2023 I would say you have a hardware issue causing a stiction effect, possibly a damaged gear or some gummy deposit or similar. In the log around time 0:02 you can see the TP is on target with about -5% duty cycle on the motor, this is normal duty cycle. Over the next 4 seconds the duty cycle goes more and more negative as the ecu tries to get rid of the last tiny bit of error, but the throttle does not move. Then all of a sudden at 0:06 with the duty cycle at -45% the throttle snaps shut. After this the dutycycle goes back to -5% to hold the throttle at the correct position. It should not need 45% duty for a tiny movement, so something is causing it to "stick". Quote Link to comment Share on other sites More sharing options...
