setting apexi for cosmo 850cc injectors

[jon103a]

hi, wondering if anyone can help,i have had a rebuild and part of it was fitting a cosmo primary rail with cosmo 850cc top feed injectors, the apexi was already set up for 850cc primarys but they were fd injectors and tuned by pip @ wgt. i belive you have to set the apexi for the injector lag times so they fire at the correct time and was wondering if anyone had the required settings or new were i can find them. many thanks jon.
