 Subject: LARRY,Fuel sync Question
IP: Logged
Message:
I am trying to set my fuel sync to +3 and I don't have a fancy meter to do it with. If I center the rotor with the #1 line on the distributor, what number should line up on the crank's degree wheel?
How many degrees will equal +3 for fuel sync?
Thanks for your help.

3 degrees on the cam is 6 on the crank. You can set a degree wheel up on the distributor and mark it out easily but if u align the edge of the rotor with the mark its usually close to +3. Make sure u dont set it at -3.

They are all set the same
crank at TDC 0
rotor tab center over cyl line on pickup plat
is 0
with a degree wheel 3 degree's befor TDC center
rotor tab over cyl line +3
The way I do it I use no degree wheel TDC crank
looking from front of truck back edge of tab
with cyl line +3
you can do it either way
at 0 the injectors fire at TDC
at +3 they fire 3 degree's before TDC
With the hotter cam I am running and a 112 center
line over the 114 stock cam I am fireing mine at
+6
using this method and than checking with the snap
on MT2500 I always get within 1 degree of what I
am shooting for
If you go behond +8 it will trip a code

Okay, so after I turn the crank over and line up 3 deg BTDC, the center of the distributor rotor should be in line with the distributor housing's "line" for cylinder #1?
That's +3 for fuel sync?
So then fuel sync +3 = 3 deg. BTDC?

P.s. Thanks to all that have posted your replies to my question.

you got it
the stock cam the intake valve opens 8 degree's
before top dead center and when this opens the
exhaust valve is also still open the scavaging
effect actualy when the exhaust is pulsing helps
pull the fuel charge into the cyl
The V6 all being a little diff run the best
between +3 and +6 the factory dealers are not
alowed to set the sync behond 0 for some reason
and your missing a lot of the scaviging effect
along with throttle response performance and gas
mileage at 0
What a bunch of knuckle heads hey
