lol thats linked to my thread, if your going by my thread on my car saying it wont work on g's with out rewiring the whole car. then this thread is far from (very technical)

simply not the correct answer to why this wont work.

If you look at the FSM you will see the 03G "doggy door" i guess thats talking bout the trunk?? anyway i call them early 03 g sedans lol. That grey connector ecu does actually not control as much as the maxima version. So im not sure if your getting your information from my maxima thread.


Its possible its not too hard to do, i really need someone with one of these cars, that wants to do this, that is would buy a ecu, and be willing to try to program nats, if it worked great, if not nats would need to be disabled via osiris. For that person i would offer a free harness to make this possible.

 

The sad part is that it's correct. Although it does NOT handle all of the functions like that of the maxima's. I did check the FSM for the 03 and fsm for the 05 and the 05's handle more functions. So obviously something is up.


Before I spend more time and money on experimenting, I rather go with something that is proven which will cost me the same and will work. I rather go with Haltech.

I have the autosport harneess

 

^Of course the 05 is different. Everything is different on those.

You need to be comparing to an early 04.

 

Makes no difference

Ecu's between 2004's and 05's even 06's are the same.

 

^Are you sure?
The transmission control changed significantly both in functionality and physical design with the 04.5
Plus all the changes in 05/06, including the rev-up.
Yet the ECU is identical?

 

hm, i will def figure it out, just kinda hard without having the car lol

did you buy a 05 ecu??

the autosport harness? the black style one?


edit, cost the same as haltech? If i was to do this swap on a G depending on what lvl of osiris, or if nats coudl be programed with the new ecu, it could be a fraction of what a haltech cost


They are not the same. 2004 uses factory narrow band o2 sensors while 2004.5 and up uses factory widebands



now if your a A/t it might throw a lil curve into it. but if your 6spd, i think this swap is not that bad at all.

 

If you want to try to get it working, id be willing to help all i can man. If u wanna email/talk on phone just pm me.


Someone that has a early 03 g sedan is going to have to step up and try this swap. I'm willing to totally help all i can and even make the adapter harness free of charge for being the initial tester.

 

I have an a/t

The A/S harness is a one off custom for the early sedan. Richard only made one because of the complexity of it. I happen to be the owner of that only one.

The wideband issue is not really a problem because if you can install an additional O2 sensor and wire it to the ecu it would act as if it were in the 2005. But again, we have to begin adding costs.

 

Just so we can keep both threads accurate and up to date.

 

have any pics of the harness, and ecu?



are you looking for a used haltech or going to go new?

 

has anybody ever swapped just the harness and ECU to test?

 

You'd have to swap the console as well......

 

I'll take a picture of it when I get home.


With ECU's I'm picky. I rather buy it new.

 

what console is different?

 

oh ok cool

and new ecu??? sorry man thats a FAIL


ive purchased 4 ecu's all for <$100 each.



why would you not use a used ecu? no wonder you could spend about the same amount of money and get a haltech??? ecu from dealer is 500+ right??


edit went and priced new ecu just for fun 350z ecu, from Courtesy 675-789 ish.
