    So to summarize, you were wrong. Glad I could help clarify. Shane, it's your turn!

    Thanks Croc. Emerald makes a harness specifically for a Duratec in a Caterham:

    I'm making my own chassis harness and will probably use this Emerald engine harness if I go with their ECU (which I probably will).

    Letís be honest on this forum. Men are never wrong. The results of their failures are usually pretty spectacular though! :-p

    My R400 has an AEM EMS-4 in it. I just bought the car so I'm still learning about it, but it seems like a decent unit. I can try to answer any questions you might have.

    In Southern California, Bisi at Bisimoto Engineering has hands-on experience tuning Duratec Caterhams with MBE ECUs as well as some other brands of ECUs the names of which I cannot recall, although Bisi had help from Magnus at the time, and Magnus has since moved away from So Cal. Steve at SBD or Simon at Meteor Motorsport are good reference sources of MBE info. At one time, SBD could supply harnesses for a variety of MBE applications, and probably still can.

    For those doing power upgrades to their existing Caterham Sevens with MBE controllers, the easiest path is an aftermarket MBE 9A4, which is pin-compatible with the "locked" factory MBE's.

    For those wishing to upgrade *exactly* along the Caterham specification curve (e.g. R300->R400->R500), we might have a very cost-effective solution for you. PM/email for details.

    When I upgraded to a 1.8K series I decided to use an Emerald. The base map allowed me to run the engine without op much hassle and the self learning loop worked like a treat. Ten years later I dropped by with Emerald themselves to have the car properly mapped after a rebuild. The only place they had to change more then a few % was low down around 2500rpm ... you donít spend enough time there with different throttle positions for the car to learn.
