Electronic ignition upgrade

Me? its not a weird curve at all. Its a normal curve with a Chrysler. When the top of the slot is shortened, the top of the curve is sliced off. People think "all in" hitting the stop of the slot at 2000 or 2400 is OK. Well its 'OK' but its not good. The Chrysler built DC/MP distributors got that right. Timing at idle was lower priority for them, and that's where they should be adjusted if the engine needs. Shorten the bottom of the slots does what we actually want to do - slicing off the bottom of the curve. Its very similar to what was done with timing for CAP, but in reverse.
