Hi,
I have a 2004 Nissan 350Z w/ VQ35 motor. I bought a brand new, also VQ35 motor with a wiring harness. What we weren't told is that the new motor is a REV UP motor so now the ECU is not compatible with the REV UP motor. Not even Nissan can tell me which ECU I need. The serial number on the motor I bought is VQ35901209. I did some investigation and it seems the Rev Up motor might be a 2006 motor and that I need an ECU MEC60 for a manual transmission. When I phoned Nissan they said that that is not the part number and they cannot help me with a price on it. I would like to try and find a second hand one if at all possible as I take it that the Nissan one will be very expensive. Please help.
