a few hints:

#you have to pull out the thin wire of the glow plug 3mm
#the wire has to light yellow-red (otherwise new setup with 0.1V higher glow voltage)
#enough pressure in the propan bottle?

maybe a new setup with rpmS 1000rpm less than now will help.

threre have been some changes made in the software, so it depends on what version you have?
since version 2.0 there are more parameters adjustable, but i do believe not the time of valve-opening (this is not the matter of no ignition)
