This dealership are very close to Nismo Japan, as they were the only Dealers for the R34 GTR in the UK etc. so i presume they just managed to get hold of it. They tried to "crack" it to then be able to remap standard Zeds but they haven't managed in the end afaik. So they then got rid of the part, which is what they sell as a Sports resetting package it went on ebay for about £360 IIRC, was tempted but decided against it in the end
