(Max Performance 93 Octane – Performance 91 Octane – Street 87
Octane). Please select the correct Power Program for the grade of gasoline you
are using. Selecting the wrong Program can cause severe engine damage. (If you
select default option, the processor will use the stock OEM settings for your
options).
7. Traction Control: If you vehicle has a Traction Control option, you can select
On to keep using your manual Off/ON button on your dash to disable the system ,
or Select Off to disable the traction control at all times.
8. Spark Timing: (Gasoline Only) Advance or Retard you ignition timing to
enhance acceleration and Horse Power. At 3 separate parameters, 0-2000 RPM,
2000-4000 RPM, 4000-8000 RPM, You can Retard or Advance the timing -14 up to
+4 degrees.
• If you are using a power adder like Nitrous Oxide, Turbo Charger or Super
Charger, than you would need to retard the timing to avoid detonation. (Refer to
power adder supplier instructions as to how much timing to pull out). If
your engine is naturally aspirated, than you can add timing, (2 Degrees at a time)
to see if the horsepower picks up. Remember that not all engines like extra
timing.
(Be careful when advancing your ignition timing, if you hear engine knock
or detonation, pull vehicle over immediately and retard the timing back to
OEM specs to avoid engine damage).
9. WOT Air/Fuel: Lean out or richen the Wide Open Throttle air/fuel Ratio -
6% to +14% to get optimum horsepower from your engine. (We recommend
the use, of an Air/Fuel Meter, like the Accel/DFI 77062 when tuning
you’re A/F ratio to avoid engine damage).
