bjmauldin Posted March 18, 2012 Report Share Posted March 18, 2012 I recently had my oil pressure sender sender moved from the engine block to the firewall, changed from a VDO to a Honeywell with a 200 OLM resistor added, and did a Dynon firmware upgrade to the newest version. On the first flight after all of these changes done together, I noticed a wide difference between the 2 EGT read-outs on the Dynon 120 EMS. On engine start the Left EGT read 873 and the Right 345. Continuing during the hour flight the Left read as high as 1300 and the Right remained around 400. Now I don't know if it was a software issue or a probe issue. The mechanic had to do quite a bit of electrical pin changes to add the Honeywell, as well as the added resistor. Any ideas? Link to comment Share on other sites More sharing options...
