Tom,

I will likely call in the next couple of days. I alrea= dy see your web site prices are a bit lower than ordering from Dynon anything else is gravy. Thanks for the offer.&nbs= p;

Do you have the sensors too? I saw the network cables etc, but mis= sed the sensors.

I still hope to get the EM2 issue licked.....it has g= ot me frustrated at the moment but could still be a problem on the Skyview<= a>.

Thanks again for the offer.

Chris Barber

I have posted in the pas= t with problems regarding my EM2 giving me wildly inconsistent= reading with my EGT's . The reading flash to randomly inc= reasing numbers up to readings of 9000 degrees.

I have now run the wirers along the outs= ide to the plane away from all other wires and still no joy.

NOW, I am having strange= readings with the coolant temperature. I have not changed anyth= ing, no movement of wires etc...well, at first, I have now replaced the sen= der with no change. What seems to be happening is that when the engine is not running, the coolant temperature seems abou= t right (which is pretty close to the oil temp....my oil temps dropped = ;quite a bit after finally getting my oil pressure up with a new front cover O-ring). HOWEVER, when I start up the engine the co= olant temperature reading shoots up anywhere from 50 to 100 degrees higher = than before I start and/or immediately after I shut down (thus not enough time to cool). It is also about the same amount higher = than the oil reading. I have removed the wire from the bundled= harness to minimize interference .

I am suddenly also havin= g an issue with the coolant pressure reading flashing to "N" inte= rmittingly (I am guessing similiar to the NOP on the tach). I too have checked the wires. = Nothing has been changed, the coolant temp and pressure just started happen= ing...the EGT has always been a problem. Again, I have now replaced all the sening units and wires.

Ok, while the EGT may b= e somewhat secondary in use, the coolant temperature is not. I have t= ried various wires. Moved wires and replaced all sensors and re-did D-sub pins.

Thoughts?

I am about two minutes a= way from ordering the Dynon engine monitor( which I intend to buy eventual= ly anyway), however, I am not thrilled at the idea of throwing money at what may be a simple fix...and may still have problem= s with even with the new unit.

Thanks.
