I'm ready to install a RPM wire from eletronic ignition PMAG to a DYNON EMS D120. According to PMAG manual there is a single wire from PMAG connector to be connected for RPM signal. Could you tell me if these signal is compatible to DYNON EMS D 120 RPM signal imput? Thanks in advance. JC. :-/

Thanks. Always learning. I really appreciate that. Ok. I´ll try to measure the milivolts with the engine running. Have any idea about the reason my EMS D-120 stop indicating EGT´s (all four) at 597~603ºF?

Hi there! I´ve measured milivolts with a multimeter at 89ºF indicated in all CHT´s and EGT´s EMS D-120 display. The values are 0,02 mV. It is a 200mV bottom of scale multimeter. The milivolts values are the same for all EGT´s. The table DynonSupport sent to me tells 1,7mV. I don´t have another...

Thanks. I´ll check it with boiling water and a multimeter. Another question, please, if the probes are Ok, what items should I have to check? JC - Aracaju - Brasil. RV-9A, PU-IJC, 143h. ::)

Just to give more info about the equipment: EMS-120, version 4.0. The EMS D-120 showed the EGT readings problem even before the upgrade the problem. I can measure the EGT millivolts. What will be an expected value for ambient temperature? JC-Aracaju-Brasil

Ok. I understood there is no problem with resistance. OK. I´ve cleaned all of contacts and measure again the resistivity. Now is 3-4 Ohms. It means no bad connection. Again the four EGT readings increase to 593-604ºF and stop at this level. What more items I have to check? Thanks in advance, JC...

Thanks Mark. Dynon support wrote there is no ground issues come in play on CHT and EGT. I understand there will be an increase in millivolts as the temp increase. If there is a bad connection there will be a millivolt decrease due to the resistivity. What I´d like to know is the Dynon EGT probe...

Hy there. Still have problems in EGT readings. It started 1 month ago, after 2 weeks no flying time. I´ve started the engine and the EGT readings went up to 593~603ºF and maintain. Yesterday I measured the resistance in EGT probes. The values looks like bigger than I´ve expected. Around 150...

The connector behind the EMS-120 is a 25 pin, for CHT and EGT. I´ll check it tomorrow, since here in Brasil is 19:43 h. May be one side is a little bit loose and a misreading could occur . Thanks. Any other suggestions?

CHT, temps, , rpm, fuel flow, all of them works perfectly, except for EGT´s. The four of them stop by 593 to 603 ºF. There is no maintenance job. The plane didn´t fly for 2 weeks. It started easily and I notice the EGT problem. The CHT´s ( four) sta around 310-353ºF. You know, living in...

Since my last flight I´ve no correct readings in all of EGT probes. With cold engine, readings is 95º F, local air temp, same on CHT. Starting the engine, the readings go up to 603 and stop there. All the connections looks pretty new. My RV-9A, has 80h the in hobbs. First flight in June, 24th...

Hy there: I´m an RV-9A owner from Brasil, with EMS-D-120 and VANS :) float type level tank probes. From 55 liters to 70 liters (full tank) there is no variation in float sensor movement. So I don´t have fuel correct indications. Is any solution already done for this?

Thanks Werner: Yes I confirm I have a serial to converter from Dynon betwen Garmin GTX-320 and Dynon EFIS D100 and cables are routed like the manual says. We tried all formats 1,2,3 and 4. There is no reply with altitude. Now I´ve installed an American King altitude encoder, but I steel need...

The altitude encoder is from Dynon. We tried format 1 and there is no altitude info in control tower. Only mode A info. Is there another point to check? Thanks in advance. JC - Aracaju - Brasil

Hi there: My RV-9A has an EFIS D100 and a EMS D120. Withe them a GARMIN GTX 320A, Betwen then an altitude encoder. The tower control doesn´t receive my altitude info. We checked the wires and ground contact. Nothing looks like wrong. The setup configuration is in FORMAT 4, the same signal for a...

:( Hi there: I´m from Brazil, and installing a pretty new RV-9A panel with an D-100 and EMS-D120. When finishing the phisical instalattion and turnned it on, there was message not recognizing the EDC-10A. The EDC´s serial number is 005072, and model is 100323. I´ve already removed the...

Hy there: I´ve bought a garmin GTX-320A xponder, and I don´t know if it is gray code signal or the same at GARMIN GTX-327. I´d like to know it in order to decide about the altitude converter module. Could you help me? Thanks in advance, JC - Aracaju - Brasil

Hy there! We connected the EMS and EFIS together in a bench, just to test them before install both on our RV-9A panel. Everything looks like ok, except we didn´t have the sensors installed. We connected the blue wire (pin 34) from EMS to blue wire pin 5 from EFIS, and the green pin 35 from EMS...

Tach Time I´d like to know the advantange to read "Tach Time". Is it used to figure out the future fuel comsumption? Or, is it used to guide maintenance? May be the best value to guide preventive maintanence is Hobbs meter time. Isn´t it? JC - Aracaju - Brasil

Is there GPS link feature already available in EFIS D100A? How could I learn the wiring tips?
