Problem: Defi EGT sensor to psi3 data monitor
 

I try to connect a Defi EGT sensor in the VFD psi3 data monitor but does not appear they collaborate! knows somebody relatively...
The EGT sensor seems ok its brand new and I measured his electric resistance and it is ok. The monitor is the most likely to have the problem because it is turned on and i set that the EGT is fitted and i get not right figures...EGT temperature always jumping for 50 degrees to 150 and back again...while engine is working in many different rpm!

Please some help!!
