• Base timing curve optimized specifically for the Miata. Hundreds of hours on the dyno were needed to dissect and then re-map the perfect timing curve. The timing curve is three-dimensional. It looks at RPM, Boost, and Timing. It only retards timing where necessary and timing is advanced wherever possible.
  
  
• Only the highest quality industrial and automotive grade componentry is used.
  
  
• All circuitry is encapsulated to provide superior protection against moisture, vibration and shock.
  
  
• Circuitry has built in safeguards against incorrect installation, improper jump starting and sudden electrical failure.
  
  
• Adjustable timing curve Ð allows up to 2 degrees of retard per pound of boost. Adjustment is incredibly accurate using our in cockpit adjuster. The knob has detents, which allow you to accurately make changes or return to exactly where you started. Each click of the knob is one tenth of a degree of retard.
  
  
• Unit is pre-calibrated to provide excellent cold starting capabilities.
  
  
• 2 year unlimited mileage warranty.
