2004 ECU updates..
Some info from TechnoSquare...
Tadashi has successfully "cracked into" the 2004 ecu program code. He is now attempting to get backward compatability with existing hardware to work with the new format, that Nissan has given to the 2k4 ecus... it seems like that the 04 ECUs are specifically made for the USA and is "one of a kind." No one else in the world runs this ECU. You may thank US emission laws.
Tadashi is still in Japan and hopefully when his health is better, he will come home..
X your fingers for the best, for both him and the new ECU development..

So... exactly what does this mean?? I know technosquare did reflashes, but like every other mod short of FI, it made like 5hp difference.
Does this mean they can make some decent power out of our ECU's now?? Im not really sure what the breakthrough is... someone clarify please!

They changed the 2004 ECU so it was no longer possible to break into--changed program code and the connectors...for emissions reasons apparently.
The reflash depends on what kind of mods you have. If you are running extremely lean (like I am, up to 14.5 a/f) then it is wise to do the reflash, if anything just to get your a/f back to normal. Doing the reflash with lots of high airflow mods should theoretically get you more hp than just doing reflash by itself...the ecu is tuned pretty decent, albeit a little lean, from the factory which is why you get minimal gains by itself.

It'll be inside a Safe with no combination.

Sharif,
Can't our eManage units handle the injector change?

good news Cheston
GQ - whats the producton date on your car? Mine is an 04 as well, and I have had a reflash since fall last year.....the newer encoding was only on later poduction 04's from what my sources have told me
