You didn't mention what the EC2 EGTs were reading but they should read 0 or 32 if jumpered correctly. They should blink only if out of limits (32 is not out of default limits) but check what the High & low limits are and set them above (high limit) & below (low limit) whatever the EGTs are reading and they should stop blinking.

Speaking of EGT's. I am using my Dynon Skyview to read my EGT's and not the EM2.=A0

With the EGT sensors not connected the EGT readout blinks. I asked you if there was a way to stop the blinkin= g and you suggested connecting the sensors to each other which I did, both = the red wire to red and yellow to yellow on the separate sensors as well as= the red to yellow on the individual sensors. None of this stopped the blinking.=A0

Do you have any other suggestions as the blinking is a bit distracting?

Thanks.=A0
