Infinity Quick Start Guide
The button labeled Large edits the CamSyncAdjustment TrigOffset [degBTDC] channel in
1.0 deg steps. The range is 0 to 719 degrees. The button labeled Small edits the TrigOffset
[degBTDC] channel in 0.1 deg steps.
The TrigOffset [degBTDC] is adjustable by Resolution. The Resolution setting has a range
of 0.25 deg to 2.0 degrees in 0.25 degree increments. This “stepping” function allows the
user to make TrigOffset [degBTDC] adjustments with the Small button up to the range limit.
Advanced Setup
Pickup sensor delay
The More and Less buttons increase/decrease the SpkDelayComp [us] value in
increments/decrements of 5.
Min value = 0, Max value = 500
Two separate procedures are required depending on the Infinity application: Plug and Play or
Universal Application.
Plug and Play
a. In the Ignition Sync wizard, select the checkbox “Lock ignition timing at” and set the “degrees
BTDC” (10.0 deg BTDC is the default).
b. Start the engine and use a timing light to verify that the crankshaft timing matches the locked
ignition timing set point (10.0 deg BTDC if using the default setting).
c. If there is a deviation between the locked set point and the actual timing observed with the
timing light, use the Sync Adjustment arrows to match the wizard-displayed value with the
actual value. As the Sync Adjustment arrows are advanced or retarded, the timing observed
on the crankshaft will change, while the “Lock ignition timing at 10.0 degrees BTDC” will
remain constant.
Universal Application
a. In the Ignition Sync wizard, select the checkbox “Lock ignition timing at” and set the “degrees
BTDC” (10.0 deg BTDC is the default).
b. Do NOT attempt to start the engine . Disable (unplug) the fuel injectors and/or fuel pump.
c. While cranking the engine, use a timing light to verify that the crankshaft timing matches the
locked ignition timing set point (10.0 deg BTDC if using the default setting).
d. If there is a deviation between the locked set point and the actual timing observed with the
timing light, use the Sync Adjustment arrows to match the wizard-displayed value with the
actual value. As the Sync Adjustment arrows are advanced or retarded, the timing observed
on the crankshaft will change, while the “Lock ignition timing at 10.0 degrees BTDC” will
remain constant.
e. Reconnect the fuel injectors and fuel pump.
f.
Once the remaining Setup Wizards have been configured, repeat the Ignition Sync process
with the engine running to ensure that the crankshaft timing matches the locked ignition timing
set point.
