Adamw Posted August 22, 2016 Report Share Posted August 22, 2016 Hi Tony,Most settings look ok to me. You might have to post a log so we can see what's going on. Your TPS lockout is set to 1% so make sure TPS at idle is 0%. Quote Link to comment Share on other sites More sharing options...
Scott Posted August 23, 2016 Report Share Posted August 23, 2016 Hi Tony,Your neutral/park step is really large, this possibly changed during he importation process and could be causing the problem.Scott. Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted August 23, 2016 Author Report Share Posted August 23, 2016 (edited) Hi Scott,I just swapped back to the G4 exteme and the car idled perfectly the changed back to the thunder G4 + and it wouldn't adjust.When you say the neutral/park step are you saying in the gear position sensor on the sequential?I turned the gear control option off and no difference.Given that I am using the same wiring harness on both ECU's, plugs A & B maybe there maybe some difference in the wiring between the two ECU's Edited August 23, 2016 by Anthony Parle Quote Link to comment Share on other sites More sharing options...
Scott Posted August 23, 2016 Report Share Posted August 23, 2016 Hi Tony,Here is an image showing the park/neutral step, this is set to 25.5%, so if the status is active it will be massively affecting the duty cycle applied to the solenoid.If you can post a PCLog of the problem occurring then we can see what is happening.Scott.

Anthony Parle Posted August 23, 2016 Author Report Share Posted August 23, 2016 Haven't had much experience with the log function do I have to set it up to display certain things or just Log and it will save everything. Attached is a log I saved today, not sure if it will help. Tony Log 2016-08-23 11;31;16 am Idle issue.llg Quote Link to comment Share on other sites More sharing options...
Scott Posted August 23, 2016 Report Share Posted August 23, 2016 Hi Tony,You recorded that log file well.I can see by looking in it that the Idle Status says 'RPM Lockout'. This is because the engine speed is more than 500 rpm above your target. It means the idle control is not trying to control the idle. In the log your idle position is between 70 and 71%, yet the base position table is asking for approximately 44%. I would say the ECU is adding the 25.5% from your Park/Neutral step as your Park/Neutral Status is off, so the ECU assumes you are in gear. You don't have a park/neutral switch to the ECU, so I recommend setting the Park/Neutral idle step to 0.0. This will then lower the idle position significantly and hopefully allow the closed loop control to achieve the idle target.Scott.
