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

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

Find_TDC on page 20.

• Roll the engine back to 50

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

Rotor_Phasing and Reluctor_Repositioning 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

Setting_The_Crank_Reference on page 25.

• 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

Dash_Window on page 29.

• Follow the additional step below to setup the cam sync.

The cam sync signal (every 360

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

Reluctor_Repositioning
