LoGear Fuel: : The WOT AirFuel ratio in first and second gears can be varied using Parameter 15 Default value is 8. Each increment higher will richen the AirFuel mixture by 2%, each increment lower will enlean the mixture by 2%.

ShiftLight: The Check Engine Light (CEL) can be programmed to light up above a set RPM. This can be used as a reminder when to shift while racing. Program Parameter8 as follows. (Param8 * 100)+ 4800 = setpoint. Programming Parameter 8 to zero (default) disables the shiftlight feature.

DFCO Delay: Vehicles equipped with lightweight or high-stall torque converters have insufficient engine braking at low RPMs for DFCO (Decel Fuel Cut Off) to work properly at low speeds. The result is RPM ‘dips’ while coasting. By enabling DFCO Delay, the fuel cutoff is only enabled at higher speeds, or when running in Drive instead of Overdrive, improving driveability

Fan Race Mode: In normal mode, the engine cooling fan is programmed to turn on at 175 degrees, and off at 170 degrees. When Fan Race Mode is enabled, the cooling fan turns on at 165 degrees, and off at 150. This essentially leaves the fan turned on all the time after initial warm-up.

Cruise TCC: Cruise TCC threshold can be programmed to lock at 45, 50, 55, or 60 mph. Depending on torque converter selection or vehicle configuration, higher lockup speeds can be more pleasant to drive.

DFCO Delay = 8, Fan Race Mode = 4, TCC: 45=0, 50=1, 55=2, 60=3 (choose) Add numbers and program into Parameter 9

Low Gear WOT Spark. Spark advance in first and second gears at WOT can be programmed to be higher than in 3rd and 4th. Default setting for Parameter 10 is 8which is 2 degrees additional advance. This parameter is adjustable from zero additional degrees advance, to 4 degrees additional.

System BLM correction: Parameter 11 can be adjusted to correct for base lean or rich conditions cause by out-of-spec injectors, incorrect fuel pressure, or other anomaly that affects the Block Learns. For example, if a new set of injectors are installed and they happen to run 10% lean, all the chip BLMs will high by about 12 counts. Parameter 11 will correct 4 BLM counts for each increment. To lower the system BLM counts by 12, raise parameter 11 by 3. Raising the value of parameter 11 richens the system, causeing the BLM’s to relearn to a lower value.
