    If you need to adjust and control the timing of your late-model GM, you need a Timing Twister! User friendly control plugs into the stock wiring harness and gives you the ability to adjust the engine's timing with the twist of a dial. The Timing Twister has four rotary dials that give you the ability to advance the timing curve, set up a step retard or even select a retard rate based on boost pressure. Control over the timing can help improve economy, improve performance and help tune the engine for other modifications. The Timing Twister does not modify ignition timing at idle, but becomes active above 1,800 rpm. Once above that rpm, the entire timing curve can be advanced up to 9 Degree in 1 Degree increments. There is another setting for a wire-activated step retard, primarily designed for use with nitrous oxide. Another great feature is for the forced induction crowd. When used with the optional MAP sensor, you can easily dial in a retard that is based on boost pressure. Twist in .1 Degree - 1.9 Degree of timing per pound of boost to retard the timing up to 30 Degree. If you ever need to bypass the modified timing settings, there's a dial to twist and the factory curve will be used. How easy is that! Go ahead, give your timing a twist!
