well it arrived today,a nice bit of kit,well made and packed,and easy to install,the motor is not in the car yet, as im busy with other things,but will give a full report asap......the ignition curves cover everything frm standard 500/126 (the first 0-3 choices) right thro another 12 curves(4-f) to play with,i cant wait to see how much advance etc i can dial in....
oh and dwell is micro proccesor controlled,and spark balence is better than 0.5 crankshaft degrees
