Type 5 - All-in-One, Crank and Cam Sync Distributor
Currently MSD makes two all-in-one cam and crank (signal) distributors (see below).
MSD all-in-one Ford
distributor Part Number 2382
Camshaft
pickup
Crank
Pickup
MSD all-in-one Chevy
distributor Part Number 2345
The All-In-One IPU distributor has both a cam and crank sensor built into a single unit.
Quick Setup Guide
• Find TDC, cylinder number one (1), compression stroke. See
• Roll the engine back to 50
o
BTDC number 1 compression.
• Install the distributor. Make sure it is fully seated.
• Line a reluctor up with the pole piece inside the distributor.
• Tighten down the distributor.
• Roll the engine back to the position BTDC (cylinder 1) equal to the max power timing.
• Phase the rotor and/or reluctor. See
and
on page 23.
• Connect the
red
BigStuff3 wire to the
violet
/black distributor wire. Connect other Distributor
wire to BigStuff3 black wire.
• Connect the BigStuff3 points wire (white) to the MSD ignition box points input.
• In the BigComm Software (Operating Configuration), set the crank reference setting to 50. See
• Verify the BigStuff3 “Dash” timing advance value to the timing at the crank. Change the crank
reference value (up or down) until the “Dash” value and the crank value are the same. See
on page 29.
• Follow the additional step below to setup the cam sync.
The cam sync signal (every 360
o
of cam rotation) allows the user to take advantage of cylinder “fuel-
phasing” (controlling the point, BTDC, when the fuel is injected into the cylinder) and individual
cylinder “timing control”. With both of the All-In-One IPU distributors (PNs 2345 & 2382) you will
need to change the reluctors to get good rotor phase for most applications. See
on page 23.
