controller will lookup a calibrated value in the table/s and multiply the fueling by that
amount and decreasing until there is no meaningful difference between the Raw and
Filtered values. So if the Raw sensor value has changed a great deal in a short period,
the delta (or difference) will be large, which will require a greater amount of transient
fueling in that cell of the table to maintain the desired AFR for that period than a small
delta would.
You may use either table, or a combination of both. (Many users rely primarily on Delta
TPS). To tune either table, set the first column to 1.00 and calibrate your base maps in
steady state condition. Then, for the columns to the right of the first one, watch or log
the delta for each RPM range as you perform throttle changes form various speeds and
loads. Set the multiplier in the corresponding table cell so that the O2 value doesn't go
leaner than your desired value and provides maximum acceleration and no tendency for
knock. A value of 1.10 equals 10% more fuel, 1.25 equals 25% more, etc. When properly
calibrated - the map will generally have the following characteristics: the values will be
small in the left
columns of the table, and increasing to the right under the larger delta
columns. Also when looking at the table horizontally, the values in the speed rows will
decrease with higher speeds.
Do not go richer than needed, or misfire and poor performance will occur.
Advanced Accel/Decel Functions:
Pressing the "Advanced" button on the Accel/Decel Fuel Settings screen will bring up the
following additional functions:
In certain cases, you may need to adjust the Delta MAP and Delta TPS filters. Adjusting
this is
only recommended for very experienced tuners. The filter constants will
affect the magnitude of the delta between Raw and Filtered signals and rarely needs to
be changed from the default values. If you need to adjust the advanced parameters, do
so with small changes! Changing the filters will require recalibration of the Transient
map/s.
The system will also cut fueling completely under hard deceleration. The decel fuel cut
will be active until the engine nears the desired speed and load. "Decel Fuel Cut active"
light will come on. Fueling will automatically be re-enabled by the system. Engines in
different applications may need different levels of decel fuel cut, and
others may not
tolerate cutting the fuel at all . To accommodate the different fuel cut tolerances, the
threshold for decel fuel cut can be set by the user for the application. The decel fuel cut
must be entered as a negative number. To disable the decel fuel cut, set the threshold to
minus 100. Do not set the threshold closer to zero than -10% or fuel may be cut too
quickly and for too long - causing erratic running and engine stalling on deceleration.
*Note: if many maps are open at once, or your PC is not fast enough - the decel fuel
active indicator may not light; even though it may be active for a brief period. The PC
may also not respond fast enough to show quick changes in the cell position highlight.
Note: The ECU calculation speed and transient operation is
not affected by this. Close
any unrelated maps while tuning the fuel cut threshold and transient maps to minimize
the effect.
Engines may also need different transient fueling depending upon the temperature of the
engine. A cold engine will need more transient fuel for acceleration than the same engine
needs once it is hot. The Advanced screen contains a table for multiplying Transient
Fueling level based upon Engine Coolant Temperature (ECT). This table is called the ECT
Trans Fuel Mult table. do not enter values lower than 1.00.
Make sure that the values
in the cells near your normal hot operating temperature are set to 1.00: any
