while having a look about for what to do next, found on the Zisco website that there is a harness extension for the EP91 and EP82, says it is needed for a Greddy emanage but also a Unichip piggy back ECU? I've got a link for the unichip website if anyone is interested, can anyone shed some light on them for me? I've never heard of them being used before?
