If they were to develop a COS for that PCM, it would just cost them $$$$ with a ROI of $0 on that PCM (retaining a customer base aside).
When you can buy a junkyard 99-02 512kb LS1B PCM for $50, it gives you inherently better table resolution AND EFILive has multiple COSs for that PCM that have been running stably for years, it makes even less sense. It's great that HPT offers an out of box solution, but I dont expect EFILive to do so considering that PCM is 18+ years old now and the business justification isn't there plus they have a solution that works with a simple PCM swap.
