Message: <blockquote data-quote="PowerArc" data-source="post: 96029" data-attributes="member: 3041">Don't confuse Firmware with the Ignition timing map (curves).Firmware is not frequently updated and was last updated 1 year ago to improve kick starting and reducing kick back when kick starting.The timing maps (curves) have been solid for a much longer time than that but can be modified if required.4 timing maps are supplied with graduated maps, you can further adjust a timing curve across the board by moving the set point of timing.Advance the TDC set point, I would not make corrections of more than 5° with this method.Program any of your existing ignitions to fit modifications you make to your engine. Raised compression, blower, cam changes, fuel octane changes, side car all would require changes some just selecting the curve appropriate and some the addition switches or sensors set to change the maps required.  i. e. engine temperature, VOES, MAP, Boost sensors, or simple relays as in a dump of NOS to retard the timing.Most can be achieved with out reprogramming and using the existing timing maps. But again it can be done if required and can't with what you have stock.</blockquote>
