So long as I can find a way of using the Emerald ecu with the S2000 clocks, I'll probably go for the Emerald. Looking second hand first however, so if anyone has or knows someone who is selling the applicable ecu (K6 I believe), let me know!

there are a few people on here that have built using the s2000 ask what they use at least u will end up with a working combination

I've asked around and it seems that omex and emerald will be the easiest. The emerald is the cheaper ecu but can't make use of the stock dash (as far as i know). The omex can but the 710 is 8 or 900 quid.

dont think the emarald runs 2 simultanious maps so the switch over to v tec can get lumpy apparently! these engines need more fuel when v tec kicks in. what about launch/traction control etc?
