Thanks everyone for all the responces and offers for help. I think I will try to tone this down a little. Make it a bit easier. How about taking the signal from the dist. with mechanical and/or vacume advance working, and proccessing that signal by adding delays. Safer and less complicated. What I am trying to do is smooth out the power from my motor. The car is a drag car with front engine, rear wheel drive. At well over 1hp and 1ft/lb torque per 10lbs weight, and street radial tires, accelerating from a dead stop is very difficult. I read that pro street stock racers use timing computers to help with traction, and guard their curves with their life. These computers are not cheap. I think they start at $700.00. So, perhaps using the original curve from the dist, and tailoring that before it goes to the ignition module would be a good compromise. John
