How come my motor seems to be harder to start or sometimes kick back?

The TC88 ignition, being a high performance oriented ignition, has a great need for proper voltage than the stock module. It is important that the battery be in good condition, full charged, and the cables be in good condition and the ground proper, clean and secure. Unlike EVO engines that use a Hall sensor that functions properly at zero RPM, Twincam engines use a Variable Reluctance crank sensor, which produces zero signal at zero RPM. The Dyna ignitions require a minimum of 60 RPM at each of the 30 pulses the crank sensor sees each engine revolution
