Okay listing items one at a time:
Anyway have a MINES ecu for R33 GTR - ecu plugs in as normal but being a MINES unit is better than standard. Think the correct term for the ECU is the VX rom??? Seal is still intacked so no one has messed with the internals. Map on ECU is said to support 400 BHP but a quick search of site will tell you all about unit.
Offers but basically I just won't what I paid for it.
