Disappointingly it would seem that Ron has changed the module for the L-Series & it now costs around £159 & is confusingly called the SYNERGY VP37 LSERIES TUNING MODULE, (whatever happened to the old £60 Tune-am TU1).
Although one of the links is for the Td4 the first section explains the L-Series. Sorry to bring you such bad news.
