Scott Norine predator711 is bringing a like-new 04 F7 EFI stocker
to tune tomorrow 8:00 AM, if he can get Bill DiFranco looneytune up
that early (Scott’s staying at Bill’s house tonight). We have a good
pile of new stuff to try, we’ll be on webcam.
In PM, Sean Ray is bringing in his dad Rex’ new Fusion600. We’ll have
baseline numbers Thurs PM or Fri AM. Again we’ll be on the webcam so
you should be able to see/ hear the numbers we come up with. We’re
planning to leave the Fusion on the dyno for a few days while we try to
find some early relase aftermarket stuff. Also Sean will be installing
the latest Windyne software which will allow us to use wide band O2
sensor to measure A/F ratio on EFI sleds. Sleds like EFI Fusion 900
require a plumbers nightmare of hoses/ connectors to measure fuel
flow–fuel goes from sled fuel pump to dyno flowmeter A then back to
the rail, then bypassed fuel has to be plumbed back to the dyno’s fuel
flowmeter B, then back to the sled fuel tank. the dyno computer
computes Fuel A – Fuel B to give net flow lb/hr. The new system will
allow us to use O2 sensor to get A/F ratio, then with our Superflow
Airflowmeter fitted, we get accurate CFM, then computer uses the known
pounds of air/hr per hour at each step to figure lb/hr of fuel and BSFC
without requiring us to get gasoline on our hands.
We have that same new software on the Cycledyn eddy current roller dyno and it workds dandily.
Those of you who registered complaints about seeing Tim Bender in the
dynocams last Sunday AM setting up an engine on our motor plate with
Sean Ray, then cameras going blank, that is the option of the dyno
tuner whether cameras are on or off.
