Tuning Tips:
The tuner has 3 methods of tuning the VE map. Once it is dialed in, you do not
need to change it unless you change the engine airflow significantly.
•
The first is manually changing the cells. It is recommended when doing this
method to reference a mass airflow sensor in the system or an external airflow
measurement and VE calculation to match the measured VE value to the calculated
value from the VE map in the ECM.
•
The second is to install a mass airflow sensor and let the system calibrate the
majority of the VE map. The adaptive VE is a very powerful function that takes
work and time out of a calibration. You can actually see the map grow and dial
itself in. Although the engine will be running via the MAF sensor, map adaptation
will only occur during steady state operation. (see the Adaptive Tuning section for
more information.) You may keep the MAF on the engine continuously, or use it to
tune the VE and remove it (don't forget to deselect it in the setup wizard).
•
The third (and most common) method for the average tuner beyond using the
default map, is to generate a VE map using the VE estimator. (see VE estimator
page for operation info). With the estimator, you can enter some basic engine data
and come up with a VE map that is adequate for most applications and a very good
starting point. You may also modify the existing base map that comes with your
factory calibration. For most average users, the VE estimator can be used, and the
tuner can focus primarily on the AFR map and Spark map for base calibration and
the closed loop adaptation will "learn out" minor inconsistency.
When using any of the methods, complete the mapping by manually smoothing points
and blending in the corners (which are often difficult to operate at when calibrating.)
Avoid step changes or inconsistent values, as this will cause erratic running. Another tip
to optimize the idle is to flatten the map slightly in the area that the engine typically
idles in. This smoothes the idle by preventing major airflow changes as the engine moves
around the cells at idle. Use the MotoBall feature to see where the engine is operating in
the map.
