Tom,

I will likely call in the next couple of days. I al= ready see your web site prices are a bit lower than ordering from Dyn= on anything else is gravy. Thanks for the offer= .

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

I still hope to get the EM2 issue licked.....it ha= s got me frustrated at the moment but could still be a problem on the Skyv= iew .

Thanks again for the offer.

I have posted in the pa= st with problems regarding my EM2 giving me wildly inconsistent reading with my EGT's = . The reading flash to randomly increasing numbers= up to readings of 9000 degrees. I replaced the EGT sensors and all wires/thermal couplers to the EGT to no avail. The= consensus has been "noise" especially since the EGT = are so low voltage.&n= bsp; I have now run the wirers along the outside to the plane away from al= l other wires and still no joy.

NOW, I am having strang= e readings with the coolant temperature. I have not changed any= thing, no movement of wires etc...well, at first, I have now replaced the= sender with no change. What seems to be happening is that when the= engine is not running, the coolant temperature seems about right (which= is pretty close to the oil temp....my oil temps dropped quite a bit&= nbsp;after finally getting my oil pressure up with a new front cover O-ring). = HOWEVER, when I start up the engine the coolant temperature reading shoot= s up anywhere from 50 to 100 degrees higher than before I start and/o= r 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 havi= ng an issue with the coolant pressure reading flashing to "N" intermitting= ly (I am guessing similiar= to the NOP&nb= sp;on the tach). I too have checked the= wires. Nothing has been changed, the coolant temp and pressure just= started happening...the EGT has always been a problem. Again, I have now replaced= all the sening units and wires.

Ok, while the EGT<= A> may= be somewhat secondary in use, the coolant temperature is not. I hav= e tried various wires. Moved wires and replaced all sensors and re-d= id D-sub pins.

Thoughts?

I am about two minutes= away from ordering the Dynon engine monitor( which I intend to buy eventu= ally anyway), however, I am not thrilled at the idea of throwin= g money at what may be a simple fix...and may still have problems with eve= n with the new unit.

Thanks.
