Abstract: An adjustable shock absorber system includes: a coil over shock absorber with a spring and a lockable adjustment ring; a protective cover assembly, optionally including top and bottom cover portions; a shock adjuster tool with a lever arm and a tool grip portion, including a band assembly, and a tool attachment assembly, including a connector member and a tool member; such that the tool grip portion detachably connects to the peripheral mounting surface of the lockable adjustment ring; whereby the shock adjuster tool can be used to adjust a preload of the coil-over shock absorber. Alternatively, an adjustable shock absorber system includes: a coil-over shock absorber with a spring and an adjustment ring; an adjustment ring assembly, which detachably interlocks with the adjustment ring; and a shock adjuster tool with a lever arm and a tool grip portion, which detachably connects with the adjustment ring assembly.

Abstract: A method of evaluating a contribution of a cylinder to an engine includes measuring a first revolutions per minute of the engine during an enabled state; determining a dwell period of the cylinder; applying a direct current voltage signal into a negative terminal of an ignition coil of the engine during the dwell period to disable the cylinder and create a disabled state; and measuring a second revolutions per minute of the engine during the disabled state. A system for evaluating a contribution of a cylinder to an engine includes a first measure module, a determine module, an apply module, and a second measure module. The first measure module measures a first revolutions per minute of the engine during an enabled state. The determine module determines a dwell period of the cylinder. The apply module applies a direct current voltage signal into a negative terminal of an ignition coil of the engine during the dwell period to disable the cylinder and create a disabled state.
