I want to change the ECU from Fadec 2002-D2 to a new Fadec 06
Can somebody give me the parameters i have to set up the Fadec?

You will need to get the SIMJET FACTORY paramters from SIMJET - Denmark.

They have developed a FACTORY download. Your best bet is to purchase your 605 ECU from them loaded with the proper program or send them yours for a download.

Hi Ocler,

Have you gotten what you needed ?

Here are the basic settings for a 2300 / 3000 with Gaspar 303 or 604 or 605 ECU

Idle Speed 31,000
Max Rpm 120,000 (2300) - 122,000(3000)

Thank you for your helpful starter. My new ECU and ancilliaries have arrived today. You very kindly offered more. I enclose a table taken from another engine approximately the same size and power and into which I have placed your figures. Please inspect and correct if you would. The figures I have put in are no more than my estimate.

Hi, Vampire.
Thank's for your info.
No i have that i need to program the ecu

HenryRG

Update- Proof of the Pudding is in the Eating/Running

My figures were estimates on the ECUs I have used in the past. My new ECU (V6.06?) won't allow you into the parameters. However I put in my best estimates of the parameters allowed in question form and have arrived at a fairly smooth and fairly fast start, using the Gaspar recommendation of the 6 volt speed 400 starter motor. All components went in as if it were a Swiss watch..

I have to say I think 900C top temp is excessive and have set mine down at 800C. Running flat out 122.700rpm (note slight initial overshoot) the temp is no more than 678 and she barely crosses 550C to get to running position. Idle seems to be at about 470/480C.
I get instant light-up with the start speed reduced to 4000rpm falling to 2000 rpm ( On none of my starts did it fail to light first time, but simply went straight on up to 15000rpm). I found the gas is cut at rpm rather than temp (per the old ECUs) and I raised this from an initial 15000rpm to 20000, as there was a definite pause at 15000rpm when the gas cut off. I brought the full starter power down to 20000 and this speeded up the start dramatically..

The main running parameters seem very good. There is very slight touch of orange/blue flame from the exhaust on full acceleration, testing at night under artificial light. I dare say in daylight this would be invisible. However I think I shall raise the acceleration delay from 025 to 030. The engine seems very stable when you cut the throttle from full to idle.

In short - I am very pleased with my upgrade.

Thanks are due Gaspar for his good advice on installation and to Vampire for his advice on the programing.

Top Limit RPM

My new conversion is now set to 123,000rpm. My, no doubt more recent Simjet 3000 with Digitech Electronics, is set to 125,000rpm. I presume the Orbit controlled Simjet 3000s were set to the lower figure and the recommendation is that this figure should be transferred into the the new ECU. My question is "Is there a good reason for this?" Would the engine come to any harm raising the the upper limit to 125,000rpm. That probably means 125,700 in practice on take off for about a minute after which the ECU should drop back to 124,700rpm for the remained of the flight. Knowing how the stresses are probably related to the square of the RPM, I suspect I woulde be wise to leave it as it is.

However I am curious. Any advice would be welcome.

Kallem

The Simjet website is saying that the AES 3000 max rpm is 125,000. I have one bought from Digitech under the name Ulysses and on that the max is set to 123,000. I am also curious that could it be run with the 125,000 rpm setting. My turbine is couple years old and if I remember correctly it should be this 2007 version or something like that.

By the way, what new features you get with the new Fadec compared to the old one? I also have this older version (v3.9 if I remeber correctly).

HenryRG

Kallem

On version 6.06, the menu system is quite different. A lot of the parameters, which used to be hidden are now accessable.

You now have the RADIO with its own menu to enable TX adjust ( as before) but also it reports any frame holds or radio malfunctions.

You have a separate START menu with the main parametres. Glo power, starter power at start and rpm for full power, pump power, ignition rpm settings (high and low) are now overt.
The gas valve percentage is controllable. I cut mine to 50% to keep the temp below 500C before it is switched off (I use neat propane and a quick release valve from a large 5Kg supply). The gas is switched off at an rpm level rather than temperature. This tends to make for a faster boot up.

You have a menu for RUN, with the usual acceleration, stability and deceleration.

You have a menu for INFO - giving runtime, cycles and last flight/run time.

You also have the plug for the pitot detector to give you airspeed. While I have got one, I have yet to try it out. You have to make you own pitot, but there are two pipe connection sockets for rigid tube.

The labeling is clearer. I have to say I like the new style very much, with its aluminum case. I have used my Merlin 90 with it all summer and found it totally reliable. I would not like to go back.

HI HenryRG,

Yes, some SimJet 3000's are set to 125,000 max rpms. It is recomended to keep your orginial RPM setting as supplied at time of purchase / manufacture.

Max RPM's are adjusted to compensate for Manufacturing tolerance variations. Thus, if youhave a 3000 w/ a 122,000 Max RPM, you have a strong / tight 3000.

While it would not be an issue to raise the Max Rpms to 125,000, as the rotating assemblies can handle this, the obvious results will be reduced Bearing life which is directly related and dependent on the amount of time spent at these higher RPM's and the condition of the current state of Balance of your Rotating assy.

Best Regards,

HenryRG

Hi Kerry

Thank you for your good advice.

Part of my problem with the Orbit ECU was there was no feedback. All you had were colored lights. I bought it second hand and the manual gave no clue as to actual idle or full throttle speeds. I just did not feel in charge or confident that the fail safe would operate as intended. However the engine itself felt smooth and nicely balanced, when spun with my fingers. So I took a chance on it. I have had a good experience with my Ulysses 140/Simlet 3000 in a Boomerang XL, so it was not a complete shot in the dark.

I now intend to fly it. (I have yet to build the model so it may be a few weeks time). The 80" span model I have in mind is designed for a P120. I am sure that being a touch lighter and rather more powerful my "new" Simjet will do very well without increasing its limit. I now have the "feel" that for an early Simjet 3000 - 125,000rpm is permisable, not really advisable and in the right model probably not necessary.

Best Regards

Henry

Hi Henry,

I agree and I'm sure you will be pleased w/ the 3000 in the XL as is as we have many customers who have this setup with our 2300 (26#) and are pleased.

hi there

how do you alter the parameters on the gsu unit

does it have to be by pc or can you do it through he gsu

many thanks chris

i have just purchased a fadec from xicoy
and i own a ulysees 140 / simjet 3000 and the gas out put on the ecu has stopped working and i need to programe the new one

you have a datacable?
i might still have the setting for the ulysses for the new ecu

Hi Sandor,
do I have the datecable, would you have the setting of the Trudo 130 for the new Fadec?
Thanks in advance
