[QUOTE="C5Performance, post: 97466, member: 2938"] [b]What is multiple spark?[/b] An ignition that produces more than one spark to ignite the fuel mixture. [b]Why do I want it?[/b] It improves cold starts, stabilizes idle, increases power without adding more fuel, reduces oil contamination, and typically reduces emissions. [b]How does MSD multi spark? [/b] Lets take a quote directly from the MSD website: “MSD’s ignition boxes feature Multiple Sparks at lower RPMS, along with a stronger, hotter, higher voltage spark to completely ignite the mixture.” MSD produces a shower or short duration sparks to stabilize spark at low rpm but shuts off around 3,000 rpm. [b]How does PowerArc/C5 multi spark?[/b] Produces up to three full length sparks from idle to maximum rpm (red line). The advantages of multiple sparking at low rpm do not diminish at higher rpm and the PowerArc system continues to multi spark beyond mid range. [b]Can you explain more about the advantages and how it affects the fuel burn?[/b] Yes, in the next post. [/QUOTE]
