Daxon 8x only 4x

hi
i have a nec2500, and despite trying every firmware, these discs only write at 4x using generic strategy, which is horrible.
i wondered if anybody could customise a firmware for me to include this.
thanks for any help.

Don’t think anyone is working on 2500 or 2510’s f/w anymore now that the 3500 is out.
