Early 2003 ECU
Since the early 2003 sedans have a few differences, one of them is the ECU. They used the older style Nissan ECU compared to what every other G35 has. Does anybody know if ECU's are interchangeable between vehicles?
Could I take one from a later 2003 or 2004 model and install it without problems?

early 03 ecu ftl - trust me I had one hahaha
I hated it, to mess with the 03 ecu you have to pull the whole ecu out, where the newer ones you could just go direclty into the obdII and mess with it from there. To answer your question I don't know, but I believe you could, because when I had a defected ECU, we test-put other ecu's into my car and it started up, didn't run just right just yet but it worked Of course I ordered a new one cause the other ecu's that were in stock didnt work just right, so I dont know

Yes, but all those tuners are idiots IMO because Technosquare cracked the 03 ECU in a little over a year. It is very possible to flash these ECUs, it's the tuners that see no market for it.

According to UpRev, uploading to the ecu for the early ecus doesn't always take. If something goes wrong, the ecu cannot be reset via the flash software. It has to be done at UpRev.
I'm working on this though. It's not clear if the flash can be done though their traditional Osris software (cable/disc) or if it has to be done by an authorized dealer.
I have the Osris disc/software. I'm supposed to use it to get the ecu version(though the Cipher OBDII stuff) and go from there with UpRev. Just no time yet.

I realize they are VIN locked. What I was really hoping for was similar wire harnesses for a direct swap. Then I'd have the dealer do a VIN switch to the new one.
Sounds like its not gonna work.
Technosquare ECU upgrade....does that change the shift points in the transmission?
Cobb AP tuner will most likely never come out. They have 1 programmer working on like 6-7 projects before they get to the Early 2003/2004s.
