Static timed at 10°, no mechanical advace, the ECU controls spark (the ECU does not add advance from 0 rpm to 500 rpm)
Car starts up fine, once I get the revs to 2500 I get spark scatter...we cut a hole in the dizzy cap and confirmed this In the picture, the rotor turns clockwise. White marks are open windows for the trigger, red mark is the trigger....black marks on the body of the dizzy are the locations of the leads for the sparkplugs. I changed the location of the LED (red mark) and it did not seem to help at all...... Attached image(s) |

the car idles and runs just beautiful right up to 2500, basicly anything over 2500 and the HT lead is too far from the rotor...when too far, the spark cannot jump the distance.
I'll be sending the picture to Link in the morning and then calling them, I have the feeling it has something to to do with the trigger windows (white marks) relative to the end of the rotor electrode. I think if I close the existing "windows" and create 4 new ones X-degrees, then I'll be okay. |
