Was just setting my trims today and realised that if you make a change that will afect the LTFT_Idle you can start the car and it will wait 30 seconds and then make an adjustment to the value then it waits 4 min to make the next adjustment. but if I turn the car off and on again then it does it again in 30 seconds so do that untill the adjustments are small or stop then go for a drive to set the LTFM_Cruise. A bit of time saved.
