hello.
I am setting RB26 with G4X.
From the engine start when it is cold (20 °) to the end of warming up (80 °), there is no problem.
After warming up, warm up the IAT to 60 ° and stop the engine.
At the end of warming up, it is around A / F14.5: 1.
It has been stopped for about 10 minutes from there, and when it is restarted again, the fuel becomes extremely thin when the restart (post-start enrichment) is completed.
It will be A / F17.0 to 18.0: 1.
If it is idling for about 5 minutes, it will return to about 14.5: 1.
