ok im having a bit of a problem with my megasquirt, again
i hooked up spark. after switching the wires around, and not having it start and flipping out, i switched them again, and it worked. but, my idle is not good. the rpms go from 700-800 rpm on a even 1 second interval. also, my pulse widths are on an even interval from 3.1-3.5, its 3.1 when the rpms are going down, and 3.5 when the rpms are going up. my a/f are going from 14.1-15.2 also on an even interval being 14.1 when the pulse width is 3.1 and 15.2 when the pulse width is 3.5. ive tried different spark angles at idle from 9-15, and none of them change the condition. any help would be great, please
