Precision Turbo and Engine BigStuff3 GEN3 Powertrain Controller Ignition Setup Tutorial - Manual (Page 19)

• Rotate the crankshaft back to 30 o
BTDC position and the voltmeter attached to the E3 and J2
terminals, the voltmeter should read 12 Volts (the Switched 12-Volt wire on the main harness
must be is connected and “live”).
• Very slowly, rotate the crankshaft clockwise towards TDC. As soon as the voltmeter reading
drops to zero Volts (or very close to zero Volts) stop rotating the crankshaft.
• Next, make sure the main wire harness crankshaft connector is attached to the stock LS1
crankshaft sensor and the main wire harness, Switched 12-Volt wire is connected and “live”.
• Attach the Voltmeter’s red lead to the main wire harness terminal J3 (Signal). Leave the
Voltmeter’s black lead inserted into the main wire harness header connector terminal J2 (Gnd).
These terminals are attached to wires routed back to the crankshaft sensor
. A jumper wire
must also be connected from pin J2 to the negative side of the battery. This test
procedure will not work without this ground strap.
•
Again, make sure the probes (sewing needles) inserted into the J3 and J2 terminals do not touch
each other. Doing so will damage the main wire harness!
The voltmeter should read 12 Volts.
• Very slowly, rotate the crankshaft clockwise. As soon as the voltmeter reading drops to zero
Volts (or very close to zero Volts) stop rotating the crankshaft.
• Take the crankshaft reading. If the crankshaft (balancer) TDC timing mark is after TDC
(ATDC) e.g. 10
o
, input 350
o
(360
o
- 10
o
= 350
o
) into the Crank Reference input box. If the
crankshaft timing mark is before TDC, add the value, e.g. 10
o
to 360
o
(360
o
+ 10
o
= 370
o
) into
the Crank Reference input box shown below.
Type 9- Ford Mod Motor - Coil-On-Plug (COP)
Quick Setup Guide
• Find TDC, cylinder number one (1), compression stroke. See
Find_TDC on page 20.
• Input 329 o
into the COP Crank Reference input box (not the crank Trigger Crank Reference
box). See Mod_Motor_Crank_Reference on page 19.
• In the Operating Configuration window, input 36 into the Pulse Wheels cell for Crankshaft
(pulses/rev). See Mod_Motor_Crank_Reference on page 19.
• Start the engine.
