Tooth Offset
The tooth offset is the number of teeth from the Home signal to the tooth that is chosen to be
the trigger tooth. The trigger tooth should be chosen so that the trigger angle is in the correct
range as described above.
Setting Tooth Offset
The first thing required is to obtain a good RPM signal, which can be checked by viewing on
the engine data in the Haltech software. With no fuel injectors connected or with the fuel
injectors disabled through the Haltech software you should get a steady 120-180 rpm signal
on cranking. Then set the “Timing Lock” to “On” the “Lock timing angle” to 10 deg and the
“Trigger Angle” to approx 70 deg. Increase the tooth offset until the timing on the engine is as
close as possible to 10 deg with a timing light (The aim is to get as close as possible, even
though you may not be able to get it exact). Now alter the Trigger Angle to line up the
engines timing with the 10deg reference mark on the engine. At this point set the “Timing
Lock” to “Off”, re-connect the injectors or enable the injectors through the software and start
the engine.
