Didn't one of the brothers pass away :-( Very sad...

OP, get your VIN number, and call up Uprev. They will tell you if it's covered. I know some non-doggy door cars still had the old ECU.

 

unplugged....

 

So i just got off the phone with Uprev and he (forgot name) told me that sedans built after October of 02 were the newer ecus and that the easiest way to tell is if your ECU plug is squared or rounded on the edges and that the rounded edge ecus were the newer ones that they support... hope this brings some more light to us early sedan guys

 

Well it looks like your edges are rounded! You seem to be in luck!

 

Very interesting indeed! You sir, have "lucked out" !!!
That is the newer ECU.
The information I gave you earlier actually came straight from the G35 Factory Service Manual, right from Nissan.
It names some exceptions to the rule on the "pre-329287" thing, but your vin/serial was NOT in the list of exceptions!
I'll see if I can get a pic.

Anyway, congrats!

 

I guess one obvious question I missed ......... Do you have a 6MT?

 

yeah mines a 6mt ... guess that woulda helped to know... thanks for all the info and taking the extra time to me out

 

^ Well that explains it.

Yeeeeaaah, ALL the manuals are the newer computer.
I guess I should have asked that in the first place

 

lol well thats good news

 

yeah, all 6MT don't fall into the "early 2003" category

 

From the pics

Gray connector = Type suck

Black connector = Type tunable.

 

basically

 

I was wondering if you’d be able to tell me if my ECU is tuneable or not? I’ve been trying to find out for so long

 

Its very simple. Look at the picture and compare it to the ECU that's in your car
