EGT and CHT bugs

[Mitja-san]

I happened to have the following problems at the first start of the engine Lycoming O-375 using EFIS SV-D1000 and SV-D700:
1. Cylinder numbering under the readings of EGT is changing spontaneously, e.g. 2-2-3-4, then 2-3-4-4 etc., instead of 1-2-3-4.
2. When the radio is transmitting, the readings of EGT and CHT are changing erratically.
Could you please instruct me what can be done to fix these problems.
I would appreciate your prompt reply.

Matja-san:

We did receive your email to Technical Support, and we did reply, but our email replies fail - our email provider says "550 Addresses failed".

Regarding Problem #1, thank you for the photos - that was enough to understand the problem. The cylinder numbers on your EMS display are changing dynamically because you have set your EMS display into LEAN mode. This behavior is explained in the SkyView Pilot's User Guide, beginning on Page 5-3.

To change back to normally ordered cylinder display, push ENGINE > LEAN.

Regarding Problem #2, we can repair your SV-EMS-220 module to eliminate this problem. To arrange the Return Material Authorization (RMA), it would be best if we can communicate via email (perhaps from a different email address?) - support (at) dynonavionics (dot) com.
