I just programmed a new PIC-version, 40 degrees BTDC and a straight line of 24 degrees BTDC.
Within the range of 2000 till 10,000 rpm the timing will be at 10,000 rpm 12 degrees.
For a normal 2 stroke Homelite this is a very good table with good values.
BUT, thats not wat I have programmed and thats the problem.
It look good on paper, but into the field it's not good.
First I was thinking it was the magneticfeeld, at high speed the feeld moves and will be smaller.
Now I use a optosensor with a window of 5 degrees, very small, zo there is no 20 or more degrees magnetic window like the hallsensor have.
It's no problem to use this software, but you have to program only straight lines and use twostroke engines
