Dick how are you reading the timing advance, do you have the Lightspeed display?

| Subject: | Need help with FloScan re-location from tunnel to engine compartment |
Can anyone point me to any installation pictures of FloScan
installations where the unit is mounted between the fuel controller and
the spider? Any links or pics appreciated.
Background:
I've decided to change the location of my fuel flow unit from the tunnel
to between the fuel controller and the spider. I've seen a few pictures
of other installations but I know I've seen some I can't find at the moment.
I've gotten quite comfortable with the tunnel installation. There's no
doubt that it's a bit inaccurate with the boost pump on but that's not
really a problem.
However, the folks at Airflow pointed out 2 other issues that I'm in
fact experiencing:
1) Fuel flow readings fluctuate a bit, as recorded by my GRT system.
It's only plus/minus .2GPH but it limits the accuracy of my nozzle
tuning efforts. I'm tuned up pretty good right now but I'd like to
improve it a bit more.
2) During full power climbs my fuel pressure drops a bit below where it
should and that causes me to turn on my boost pump for short periods of
time midway up during my climb outs. I can't recite the exact reasons
for that as described by Don Rivera at Airflow, but it's related to the
restriction of flow sensor and it's location between the tank and the
engine driven fuel pump. As I understand it, it's best to have as few
restrictions as possible upstream of the fuel pump. And having
inadequate fuel pressure during full power operations is undesirable.

Yes, the Lightspeed display module.

Doesn't answer your exact question but I mounted my floscan to the lower
engine mount crossbar. I used Adel clamps to attach a 2X2" aluminum
angle that the floscan mounts on so it's between the mechanical pump and
the fuel servo. The reason I did it that way is I've installed an iSTART
system that injects fuel into the air intake past the fuel servo. See
it in use here: http://istartair.com/. If I placed the floscan between
the servo and spider the fuel usage wouldn't be as accurate as I want.
You reminded me to take pictures which I'll do after Sun -n-Fun.
