Done a bit of idle tuning. As occasionally it could stall when slowing down to a junction.
There and many ECU parameters to do with idle. One bring through STIT variable, this is a tweak value of the IAC is the idle rpm didn't match the target.
Just needed to log the STIT value while running from cold to warm in the garage. Use these values to modify the desired air flow table.
After that done a few hot starts, all working perfect. Should have done this ages ago. Real test will be on the next drive.
