ACTUATING N2O
nstall all your N2O hardware according to the manufacturer’s instructions. If you are
sing an A
CCEL
3-STAGE REV-LIMITER to trigger N2O, follow the Rev-limiter’s instructions.
using a third party’s actuator, follow that manufacturer’s instructions.
our new A
CCEL TIMING COMPUTER
as two RPM-Activated switches connected to two 2-pin connectors.
Use one of them to actuate N
2O.
or consistency use the connector
ith the B
ROWN and PINK wires.)
ssemble it by splicing the N2O
olenoid’s Red (+) wire
o the Pink wire, and its Black wire to the Brown wire.
he N
2O solenoid is actuated through one of five possible connections: one of the two
-pin connectors coming from the Timing Computer,
OR one of two 2-pin connectors
oming from an A
CCEL 3-STAGE
REV-LIMITER
,
OR a third party actuator.
Both 2-pin, female output connectors are switched to Ground inside
he Timing Computer, and both connectors supply enough power to
rive multiple solenoids. Two solenoids, wired
n parallel, is common but different solenoids
may have different energy requirements.
he
ACCEL TIMING COMPUTER can drive up to three HURST solenoids (Roll Control solenoid
alve – Part# H566 7550) wired, in parallel, to either of these two 2-pin outputs.
N
2O makes more oxygen available for combustion and the air/fuel mixture burns very fast.
s a result, the mixture should be richened and the ignition timing Retarded.
PROGRAMMING NITROUS ACTUATION
he connector with the Red & White and Black & Pink wires is programmed by the RPM
nd N2
O RETARD
buttons. These buttons and this connector do not effect N
2
O retard.
1. Decide at what
RPM you want N2
O to be activated.
2. Press RPM and N2
O RETARD
to display its current value.
3. Adjust the value with the

buttons.
4. Press SAVE to store the new value.
PROGRAMMING
NITROUS R
ETARD
(Through the Flat, 4-Pin Connector – See Pg 10)
o matter how N2O is triggered, the Timing Computer reads when it has been actuated
hrough its flat, 4-pin connector. The buttons and connectors do not affect N
2O actuation.
When the N
2O solenoid is actuated the entire value set for N2O Retard is immediately
ubtracted from the timing curve.
1. Decide exactly how much Retard you want.
2. Press the N2O RETARD button to display its current value.
3. Adjust with the

buttons.
4. Press SAVE to store your adjustments.
