Im trying to decide which ECU to go with for a 2.0 Duratec HE in a Sylva J15 and currently looking at Omex or Emerald.

Has anyone got any recommendations for rolling roads/tuners in the Hampshire area with expertise in either of these ECUs?

Try JKM for Emerald, I use them for my MS unit, (although he doesn't like doing them, ), but he is the local agent for Emerald, and recomended by Dave Walker. JKM Motor Services Ltd, Bold Close, Portsmouth, PO3 5RD. Tel: 02392639933.
