Steven:   I've followed Megasquirt for quite a while and it looks 
impressive.   I also know that setting up the operating parameters of an ECM 
is not very easy.  Have you done one and how long does it take to set one up 
where it makes a good running engine?  Can a beginner program one?    Thanks
Jim
