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) |

Where is your pick up reading from? If you are reading from the factory dizzy did you lock out the factory advance mechanism? Since the computer controls the timing there is no need for the dizzy to do anything but rotate. Lock the advance plate out and it should be good.
