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.

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.


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.

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.

Hope this helps
