RedZero Posted August 19, 2020 Report Share Posted August 19, 2020 Hi guys ! I would really like so help over here. Since a while back my car has issues being on idle. It just keeps oscilating on engine RPM`s. without A/C on and even worse when A/C is on. when driving the car is running smooth with no problems at all. I already did some reseach here on the forum, had a topic with similar problems. tried the settings on the ECU provided on that topic, but it didnt seem to help. might even got a little worse, I already checked out the obvious places for a vacuum leak but didnt find any I made 2 logs, 1 without AC and 1 with AC. can you guys take a look and maybe help me out ? idle oscilating no AC.llg idle oscilating WITH AC.llg Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 19, 2020 Report Share Posted August 19, 2020 We need to see what your settings are to suggest what to adjust. Attach it just like your logs above. Quote Link to comment Share on other sites More sharing options...
RedZero Posted August 19, 2020 Author Report Share Posted August 19, 2020 oke, i think this should be the right file. This one was from earlier, before i tried the options of the other topic. Backup 19-8 idle.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 20, 2020 Report Share Posted August 20, 2020 Ok, mostly your E-throttle target and base position table were completely wrong. But I think the main ignition table and idle ignition table could be improved also to give much better torque control around idle. So in the attached file I have changed lots, it may not work well initially so dont fret if it still no good. Please load this map in and do another log, I may still need to make some tweaks. Oh please update to the latest firmware also before doing the log. There were a couple of improvements to idle control in 5.6.7.

RedZero Posted August 20, 2020 Author Report Share Posted August 20, 2020 Thanks Adam ! I will load it up, try it out and come back to you ! Quote Link to comment Share on other sites More sharing options...
RedZero Posted August 22, 2020 Author Report Share Posted August 22, 2020 Oke, I updated the firmware. Loaded the file. When i first started the car it had a bit of an issue idling. But when I touched the gas pedal it was gone and havent returned ever since ( but didnt start the car cold again). The car is idling normal now, only I forgot to test it with A/C on I will make a log for it next time. Thanks again Adam ! Quote Link to comment Share on other sites More sharing options...
RedZero Posted August 26, 2020 Author Report Share Posted August 26, 2020 Oke ! had some time to do some driving and logging. So in quick, - The car at cold start is still having some issue`s. - Warm idle is perfect. With and without A/C. - When driving with A/C on it looks like its being held back when light on the throttle. (i dont know if it is related). Car runs good, from 0, the car accelerates real smooth. so thank you Adam for that maybe you can take a look at the cold start ?

Adamw Posted August 27, 2020 Report Share Posted August 27, 2020 Mostly the idle ignition lockout was too low so wasnt kicking in when cold due to the higher target speed. Made some tweaks below, it should be closer. New idle V1.1.pclr Quote Link to comment Share on other sites More sharing options...
RedZero Posted August 28, 2020 Author Report Share Posted August 28, 2020 Adam Oke, loaded up the V1.1. Car runs almost good. After the start up the car died after a couple of seconds. After the restart it is fine. only a really light change of rpm. but amost not noticable. Idle v1.1 died at cold start.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 28, 2020 Report Share Posted August 28, 2020 The stall in that log is not caused by idle settings, I suspect the cold start enrichment or possibly a couple of cells in your fuel table arent quite right but with no lambda we cant really tell.
