Lumi probe TECHNICALLY requires knkwing Cetane of fuel to correctly time engine.
Clamp method is for sure the simpler method and for what we do bang on.
Sand off paint as closr to injector #1 or 4. 1 is usually trucks 4 is usually vans. Attach clamp and ground clamp to line.
Route lead carefully and avoid belts pulleys etc.
Take a 5/16" drill bit...clean out MAG probe hole on timing tab...it is the taller of the two; short one is 0 deg and is not used for pulse method. Locate groove in harmonic and clean it out wjth O ring pick or something.
Take 3 or 4 business cards place them between harmonic balancer and timing tab...creating clearance so mag probe does not contact balancer. Insert probe till contacts cards route wires safe from harm and remove cards.
Connect leads to meter please insert carefully and square to bore...also remove carefully and square to bore...or meter may not function correctly.
Connect battery leads set offset to 20. Fire up truck run up to 2000 rpm read timing.
Easy peasy and @
