Is there an updated gps engine we can fit in the 302ddv to keep these
units going as an fai logger?

Since FAI issues approvals for each individual model of logger, does this

modification mean that the logger is no longer an approved model and
hence no longer valid for badges, records, etc?

I genuinely don't know if this would be the case: can somebody who is up
to speed with GNSS approvals comment?

You are right. When approval is first given, each manufacturer agrees to
certain conditions, which are listed in the Specification Document. Amongst
these is:
/*
Notification of any intended change to hardware, firmware or software must
be made by the manufacturer or applicant to the Chairman of GFAC so that a
decision can be made on any further testing which may be required. This
includes changes of any sort, large or small.
*/

GFAC may decide that further testing is required, or may just revise the
approval document to reflect the change. I do not speak for GFAC.

However, there may be a further difficulty. The firmware may need to be
changed so that the correct GPS engine type apprears in the IGC file. I am
not sure that the source files for the firmware are accessable any longer.
