 +===== Ultima - Nosecone Ignition =====
 +
 +The Ultima Ignition Unit (53-644) is very similar to the Dynatek 2000i product (although the programmed curves appear to be different). It is a self-contained ignition module meaning the timing sensors are built onto the same timing plate, located in the '​nosecone'​. The timing rotor cup passes thru the sensors on the back of the timing plate to trigger the ignition module.
 +
 +The Ultima unit triggers the coil primary circuit - either as a dual-fire system (one trigger) or a single-fire system (two trigger signals). It also has an output for a tachometer and also has an input for using a VOES to alter the spark timing during idle & cruising.
 +
 +The install instructions are here: Ultima 53-644 [[http://​www.ultimaproducts.com/​53-644_Ignition.pdf|Installation Instructions (2012 version)]]\\
