Ok, i'll try these tips (check connectors and cheap fuseholders)

I also seem to remember this issue (or a similar one) here in the forum, but i cannot find it in the history.

No, it is Jabiru 3300. The thing is that while stopped and low RPM, the values are ok. At cruise, goes from + to - cycling.

Hi all. My Dynon EMS 120 shows Amps fluctuation at high RPM (actually an RPM different than stand-by). From positive readings to negative randomly. Before switching on the engine, it works (checked with a fluke amp meter). After switching on the engine, while warming up the engine, also...

Hi all, Finally, the problem was FOR SURE a bad CHT temp probe installation. Although the ring diameter is the correct one, there is no space to put it correctly, and there were gases coming out wich means bad temp reading. We installed the probe near the spark, in a bolt. The measure is not...

I also doubt to get a response from jabiru; i already wrote in the past for another issue and nothing. The bolt used is the one wich is directly over the exhaust valve, at left or right of the spark (is a little bit hidden inside the fins). I saw this recommendation here...

We are using 12mm terminals. The problem has been solved (we hope). We changed all the CHT probes to a bolt plug, instead of the spark (the bolt wich id over the exhhaust). Now, the temps are extremely different. We have contacted Jabiru just to know how accurate is the new place. We dont...

What do you mean with that? what plugs are you talking about? (sorry, my technical english is not very good). And by the way, i also don't understand this sentence: The detergent trick is a good idea. Ill try it next time just to see. Regards,

Update: It is clear to me that the connector cause a mistake in the reading. We have recently tested the CHT probes (through the connector) with boiling water and comparing with an accurate thermometer. With readings from 30 to 120 degrees, the difference was not significant (usually 2-3...

To use a dedicated set of cables is another possibility if the already installation matches wrong temperatures using a boiling water sample. Ill try first this, before purchasing another set. I am using the plug sensor under the spark; what do you mean with "tricky to get a good seal"? Tight...

The junction at the firewall is a 12 pin connector wich allows you to have an independent installation in both sides; it is not a thermocouple junction. But, the reading looks to be higher. Im going to test the reading removing one probe from the spark and introducing it into boiling water...

Will this Carb air temp sensor be correct in a Jabiru 3300 and Dynon EMS D120? Carburetor Air Temperature, 1/4-28 UNF, -50 to 150 F (Aircraft Spruce PN 10-01846) Regards!

And by the way, after 2-3min climbing almost ALL of the cylinders goes to RED zone, so the problem appears to be in all of them.

Hi all, We have recently mounted an EMS-D120 with a Jabiru 3300A. The problem is the following: CHT readings at ambient temp are normal; also EGT; all of them matching aproximately the same. Applying power, the CHT increases (wich is normal), but it goes to RED zone in 2 or three cylinders...

So you mean, the 12v transducer output of the jabiru only connected to the auxiliary tach, and the alternator wire connected to Dynon RPM left, using a 30k resistor (if necessary). Right? What if i connect the transducer output directly to the two sensors... Just wondering...

Celsius please!

Hi all, i have founded in old topics a file with recommended thresholds for Jabiru3000 (solid valve). I am now installing a Jabiru 3300A (Hydraulic Valve). Some thresholds are easy to find in the motor manual, bur others aren't. Also, i am a little bit confused with the meaning of the TOP and...

Hi all! i am currently installing a D120 with a Jabiru 3300A. The tachometer connection between the transducer and the D120 works perfectly, but now i want to have a secondary external tachometer. How do i connect the second one? Parallel connection? directly to the two wires of the transducer...
