There are a few up and running. APS has tested their's on 05's and haven't had any problems. Same with GReddy.

And actually, it's just a myth, any 350Z's made around August 2004 and on have the same ECU, which uses wideband O2 sensors. Some are 2004, some are 2005. (the 2004's are often called 2004.5)

It should work fine though, the timing to retard and some other things will most likely be different than they are for 350Z's made before Aug. 2004.

Correct me if I'm wrong, but 2004.5 models went into production in April 2004 I believe. Anything manufactured in August 2004 should be a 2005.

I'm not talking about the ECU switch. I'm talking about model years. A car produced after July 2004 would not be part of the 2004 model year. It would be part of the 2005 model year

I dunno, i'm just talking about the versions of the ECU. What year they are considered doesn't matter to me, it's any 350Z made July 2004 or after.

I only brought it up cause you mentioned MYs in an earlier post and you know how confused people can get. I just wanted to clear any of that up before it started.

I think we agree: 350Zs made August 2004 or later (model year 2005) have the new ECU. All others Zs have the original ECU.

I have a late model 2004 and installed the APS TT. I was getting Bank 1 O2 senosor codes. Is the wideband sensors more sensitive than the earlier (pre-2004) models? I put test pipes on and now the codes are gone. Could some one clear this up? Peter from APS says nothing changed in terms of the ECU's.
