EGTs for a 912 ULS, What is typical?

I typically see 1300-1350 with my early SN RV-12.  A friend's RV-12 runs about 100F higher.

Photo attached is typical cruise...

This has always confused me as well. The  manual says 1470 is normal . Neither of my engines ever run at 1470. normal is average cruise is around 1200. SOme mechanics say cooler is better others say hotter is better. Rotax manual says 1470.

what is the correct answer and why does rotax recommend 1470 if mechanics disagree? Shouldnt we lean these engines to 1470 average?

 No one mentions there are warmer cylinders and cooler ones. I go by the hottest one?

Fred:

Thanks for response. 

Two questions:

1.) Which document does Rotax specify the 1470 F value for EGT? I see where Van’s calls it out. But, not Rotax. 
2.) I don’t understand your comment about adjusting mixture. The 912 ULS doesn’t have a mixture control.  So, how would one do this?

Thanks.

In reviewing the Rotax  documentation for the 912 ULS EGT limits, the only specification that I can find is a maximum limit of 1616 F (880 C).  Nothing that specifies a different limit for take-off and cruise and nothing that specifies a maximum difference between the two readings.

Is this the understanding that others have?

Thanks
