Ok got a VS 5litre v8 running with a wolf 3d. Problem is when the input trigger is set to rising edge as per the manual the spark is about 40 deg further advanced on the crank then its set as, eg. the timing is set at 16 deg and timing light shows 50+ degs. When i set it to negetive trigger it gets closer but still about 10deg out.
The rotor button phasing is done as the manual says and double checked and the setting in the wolf for btdc is set at 60deg as the manual says. The spark also is not steady, it jumps a couple of deg up and down when the revs are steady. Help please!
