Profiler Tips
The Davis Technologies Profiler is a powerful tool, not a miracle
worker. As with many products, it still requires input from the user
to work from. Here are some tips that might help get you going
quicker and faster sooner.
Base your initial Profile on some of your best passes. Import
several logger driveshaft data runs and let the Profiler
average them to create your first profile as a starting point.
Be realistic with your base timing numbers. The Profiler can
add timing as well as retard it. Keep the timing numbers
realistic, especially with nitrous cars, to keep the intake on
and pistons in one piece. (upper & lower timing limits)
Use the
Zones
to build different parameters into different
areas of the run. From 2-3 seconds into a run, you may not
need the timing corrections that you use early in the run.
You will find in most cases the
Smart Drop
™
is your friend.
Once your upper timing correction range (Red) reaches 76%,
the Smart Drop
™
function becomes active if it was enabled
in a Zone. Depending upon what level it is set at, it will drop
a random cylinder(s) and never the same one twice. With a
nitrous engine a setting of
1
is recommended which has
proven very effective. The higher the setting the more
cylinders it will drop.
Insure
NO
grips are below zero! If the Profiler sees a grip
below zero, the Profile will not upload from your PC to the
Profiler. If you keep getting error messages or file upload
issues, go back and check your Profile near the zero time
point. Zoom in the view on the first few Grips to check.
The width of your correction ranges will affect how
aggressive the corrections will happen. The wider the
correction range, the less aggressive it will be and the
