Thanks for the suggestions guys.
The problem has gone away (for now). Car is starting quickly on the first crank attempt warm or cold, and is generally being awesome as usual.
The only thing i've done is adjust the RPM lag factor (it's at 70) and literally drive the car.
I have condensers and a ...
