Small micro interruption on 912iS engine (2)

Interchanged injectors of cyl 1 with cyl 3

Had the problem again about 2 min after TO, resettable. Then for a while small power interruptions without the red light on lane B. I changed the Injectors back and dit another Testflight. See datareading on screenshot:

 I will go and change Injector 5 on cylinder 1, i ordered a new injector.

Update from 24 January 2022
 Replaced today injector 5 with new one. Still the same problem. Two minutes after take off lane B light came on, see picture. Reading normal batt voltage on plug for injector 5, looking for bad contact, all good.

Verify that you swapped BOTH injectors on Cyl #1 with Cyl #3.

Your 3rd  photo is completely understandable.
Lane A is reporting "No Data Received From Opposite Lane" Because the Lane "B" power Switch is Turned OFF.

You have an intermittent but consistent Injector #5 Problem.
Try reseating Fuse F23 in the Fusebox.
Unlikely, but have you tried reseating the Connectors on the Fusebox?

Replaced injector 5 (Cyl 1) with new one. Testflight: still the same problem. 
Installed "old" injector 5 in place of injector 1 (Cyl 1), then Testflight again: same problem. ????

Changed all 8 spark plugs again, made testflight today: All good now, so far!??
