So, if I understand you correctly, I could change over from the D581 t= o the D585 coils without requiring any upgrade to the EC-2?=A0

Don't forget to do the coil disable test to check for failed coils = prior to every flight.

I have a set of the D5= 85 coils but have only evaluated them on the bench for compatibility with t= he EC2/3=A0 (they are).

I do know that the previous version of the t= ruck coils (D581) are not as reliable as the D580 (Corvette) coils.
