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.

I have a corporate account with Nissan/Infiniti. I can get just about anything cheaper. But going with ECU's it's best to go with a virgin system (with warranty)

Not that it will not work. Just the amount of energy that it takes to make it happen I rather go full standalone. It'll give me more control over the engine than the OEM Ecu can. In the event I decide to go boost, I'd be able to program the system to work boost by gear, etc...

Anything can work with the right amount of money thrown at it correctly. But is it cost effective?

I can see where your coming from and for you a haltech is most def what you need to do. But i'm trying to make this possible for everyone as i dont even have a G.

Yes i do believe its cost effective on thats if you get the parts cheap enough. I'm not sure how good a corporate discount is but it would have to be a lot to make this cost effective over just getting used parts.

Depending on how you want to tune, basic reflash, full on tuner version. This swap can be done fairly cheap. Also once you have the black connector ecu you can run whatever system you want. A really soild system is a reflash on the stock ecu for speed, dtc disable, etc, then a haltech. Also that way the haltech retains its stock harness, if it was ever sold or something.


On a side note are these early G's the ones without HID's??? Its amazing how infiniti done that, while my 02 maxima has factory hids.

I am in for any solutions.... I thought I was safe because I had no doggy doors and HIDs but noooope i have the untuneable.

Other alternatives other than a reflash? Are any decent standalones affordable? I am hoping to get tuned for full exhaust + Plenum spacer + CAI.

Planning to get cams and polished heads and all that stuff at some point....

Options are Available, right now not many have done anything tho.

Currently working on, the ecu swap. Slow Progress

Easy way out, PNP Haltech just a little costly but a solid tuning device. Im also working on this. ()


Soon there will be more information on this.

So by simply swapping Wiring harness with a 2004 (5AT) and also the ECU from the same we should be able to maintain function of most things - but NATS is the issue correct?

^^ There's nothing easy about it, and I don't even think it's even been done. There are just too many other things that would have to swap as well... BCM and entire engine harness for example. Why waste so much time for something that might not even work, when its far, far less expensive to just trade up to the year/model you need.

Working on testing all of this out ASAP, currently making a adapter harness, no need to swap the entire engine harness.


Will know exactly whats going on soon!


Main things:

NATS

MIL light

Auto Trans




There will be a new thread once some testing is done.

good to hear

all 2003 with the early ECU are 5AT so they will all be the same

Why is the MIL function off?

MIL functions differently.
On the 03.0 there's a wire straight from the ECU, on the newer ones it's a signal that goes over the CAN bus, the dash picks up on that signal/message, and illuminates the MIL.
Worst case scenario, you would have to program an ELM 327 to constantly scan for a MIL on the OBDII diag port, and send power to the MIL wire on the 03 dash.
Although there's a small possibility that the 03.0 dash/gauge cluster might just light the MIL from either the input wire OR the CAN bus, that would be really nice, but that's just complete speculation at the moment.

Sub'd. Just bought a cobb ap from a member here thinking that it will work, unfortunately, I now have a $400 paper weight

I have an early 04 (manufactured 07/03) and a manual transmission. I am really interested in further progression of this concept. I don't have the $$$ to buy a full standalone (haltech, aem, etc) so for now I'm left tuneless. I wanted to get osiris, but if the cobb ap won't work, osiris probably won't as well.

Im 99% sure this ecu issue is ONLY for Autos.


so you should visually check which ecu you have,, if its the black connector ecu osiris should work for you.

^+1. All the MT's have the newer ECU (Osiris compatible) as per the Factory Service Manual.
