oetoet Posted May 2, 2023 Report Share Posted May 2, 2023 hi guys, question, while driving with this car to setup a base map, the revs rise about 200rpm every time you press the clutch to shift. all harmless, as they come down eventually, just annoying. can anybody spot the culprit? file and log attached. tt anouk.pclx PC Datalog - 2023-05-2 5;49;02 pm.llgx PC Datalog - 2023-05-2 5;49;02 pm.llgx tt anouk.pclx Quote Link to comment Share on other sites More sharing options...
koracing Posted May 2, 2023 Report Share Posted May 2, 2023 I would zero your dashpot offset (currently set to 1%). When it's idling at the correct RPM it's only at 2.5% throttle at the end and the dashpot is adding 1% making it hang high. Your AC active is adding .5% - is that actually required to keep it idling properly when the ac is engaged? What happens if you put idle control in closed loop?

koracing Posted May 2, 2023 Report Share Posted May 2, 2023 The dashpot is still too high, but it looks like the e-throttle isn't following your commanded position very quickly - you likely need more integral value on the E-throttle PID.

Okay, will try tomorrow, its 22:25 here. Thanks for your reply and time! Quote Link to comment Share on other sites More sharing options...
oetoet Posted May 3, 2023 Author Report Share Posted May 3, 2023 dashpot set to 0 and raised the integral value. issue is resolved! no more rev hang while inbetween gears. thanks! Quote Link to comment Share on other sites More sharing options...
