I also have an ELNEC PREPROM-02aLV which is the
mutt's nuts - I'd have
bought one of their entry-level universal programmers had Dataman not
snagged the UK distribution agreement and jacked the prices up. From
what I've heard (but have not confirmed - YMMV), you also have to use
the Dataman-branded version of Elnec's driver software, which lags
several version iterations behind and (last time I checked) didn't
receive the "beta" device-support or AlgOR updates.
AFAIK this is not true. Why don't you download the updated software from
elnec site and try? :oP
