What Happened? Did your vehicle go faster? slower? What did the engine sound like? Did the nitrous system work?
Refer to the timing charts, and examine spark plugs for signs of detonation.
a.
If power increased or vehicle mph increased and your spark plugs show no signs of overheating or detonation, you
could try to increase ignition timing 1° to 2°.
b.
If power increased or vehicle mph increased and spark plugs begin to show slight signs of detonation - STOP! Do
not advance timing further. You may choose to reduce timing 2° at this point for an extra margin of safety. At this
point, you need to look at the “Troubleshooting” section for assistance. Pay close attention to the fuel supply with
your nitrous system.
c.
If power decreases or vehicle mph decreases, check for burned spark plug or engine damage, and reduce ignition
timing 2°. Please refer to the “Troubleshooting” section of this manual for help in determining any system trouble
you may feel that you are having.
