Hi Buly
Sounds like things are sounding good {:>).
Buly, I could be wrong, but I don't think you can copy map from B controller to A controller - only the otherway around.
I did not think so, but wanted to make sure.
If I understand you correctly, you are finding that your engine runs better on Controller B rather than A. I presume that Controller B is still in its default settings ( meaning you have not tried to change its fuel MAP as you probably have with controller A).
If that is correct, then all you should need to do is return controller A to its default condition which should be the same as controller B default and then controller A should provide what you want.
To do this, power to the EC2 and injectors must be OFF - BUT, the injector disable switches should BOTH be set to ON (You may need to pull a CB to remove power from your injectors with the injector switches in the ON position).
If either of your disable switches are turned off while doing this it grounds the cold start circuit - and if you reset the controller in this condition, it resets the MAP default to Tracy Crook's PERSONAL default MAP rather than the generic default of controller B.
This point is a news to me. I'll try it per your instructions
You set the switch to controller A and put the mode selector to mode "1" (one). You then push in the program button and hold it in while you turn power on to the EC2 controller. Release program button after 2-3 seconds and you should have mode A programmed to its default.
The reason you need to remove power from the injectors or otherwise make certain there is no 12V to the injectors (by means OTHER than using the injector disable switches) is there is a sneak circuit in the EC2 which can provide power to the EC2 through the power feed to the injectors - even though your EC2 power switch may be off. If that configuration exists, then you may think you are holding the program button before you apply power - but in reality power is already there and therefore, you will not be successful in causing the controller to go into the default MAP mode. Now if you only have one switch that removes power both to the EC2 AND the injectors (like say a MASTER switch) then that is the only switch you need to worry about.
That's what I usually do. Just turn the master ON (everything else off) while holding down the program button. But I'm not sure if there is a sneak power to the injectors? I'll check that.
Can't help with the EM2 as I don't have one.
1750F at full throttle is not unreasonable. EGT can vary from installation to installation depending on what type of EGT probes you use and how far they are positioned from the exhaust port. The closer generally the hotter, long probes which protrude further into the exhaust flow will also show hotter temps.
My probes are 2" away from the ports and protrude about 1" in to the middle of the exhaust pipes.
I run today my engine with the new muffler with good results. Got 6000 rpm static with 78" IVO Magnum 2 blade in fine pitch and the noise was very acceptable. My questions are:
The plane run much better on computer B. Can I copy B to A?
My EM2 always shows EGT for Rotor 2. I can not figure out how to monitor 1 & 2 so I can adjust the mixture to match. I know #2 is running leaner from looking at the exhaust ports last time I had the headers off. #2 is brown and #1 is black. Unless keep I #2 until #1 pops up?
I was seeing EGT's around 1750 at full power. Is that normal?
