I have been posting on this thread on why my EKO 25 had a hard time keeping up when it's cold. It dawned on me that I can't remember what settings were when I got it so I start playing with thsettings. Problem is I don't know what is best or even what is default. What do you all program your settings to. This might be part of the problem. I read someone on this thread using 5 for Hesterises (SP) I had it on 3 and goes to 10. This may be part of my problem I have now idea what they even mean . Thanks. ihookem.
