Anyone interested in working with OPENECU group to develop G35 compatible version?

I know we have alot of programmers and engineers in here. Anyone care to form a group to work with OPENECU to create infiniti version?
I think its very much do-able if you get enough interest..

1. Study current ECU.
2. Use OPENECU.org (ECUFLASH) and develop an interface for INIFINI.

I think it would be interesting... I've been using ECUFLASH for EVO and SUBY for many years and have had a good results.... This will benefit all G35 owners and possiblility of making tremendous impact on self tuning arena...

What do you think?

Dan.

lol dude our ecu are faaaaaaar more advanced than anything that will be in a evo or suby. its one thing to make it work. another to actually gain power. and another thing to make it last and not blow up.

Care to elaborate what is far more advanced in INFINITI ecu than EVO or SUBY? Yes, you can blow up an engine if you have a garbage tune. I know we all know that.

You commented that COBB ST2 yield only a little but PROTUNE yield more.. Yes, customized tune yields better majority of times... Do you think that COBB software had a problem???

"The OpenPort 2.0 J2534 DLL primarily follows the specifications of J2534-1" --
I guess this is good... Infiniti tech website shows that their software is based on J2534-1... ()

I will test if OpenPort 2.0 can be used....
If someone is rich, please invest in "/ this guy. Assuming you have a connection with Infiniti, you at least be able to use their software...

I will help you to develop a software for infiniti... ; )

Go ahead and try it but all my understanding has been that all top companies such as Techno, Cobb and BD all had problems with accessing and editing the G's ecu and had many posts on this problem, so that probably why he said that infiniti's ECU's are more complicated, but give it a shot you could turn out to be better than all those companies

I could help in developing software/interface to our G's.

I thought the ECU was already opened? GTM is for sure using OSIRIS and flashing the stock ECU as part of their TT kit.

I tested with Tactrix (Openport2.0) cable and was able to connect to the ECU. I had 2.6 beta for EVOSCAN software and It made connection to ECU. Next step is to write up simple program using J2534-1 API.....

It's quite a bit of work reverse engineering it as far as I know.. A friend of mine at UpRev mentioned they've been reverse engineering with multiple developers for a few years to get where they are at. Granted they've made something much fancier than the original firmware, and for many flavors of nissans.

I bet it would be fun though, personally it would be easier to just pay for the uprev license for around 300 to have the fruits of their labors, I think the cable is another 200 or so if you want to do the flashing yourself.

I agree, UpRev is definitely the way to go with the Nissan/Infiniti stable. It works all the time, no fuss, no errors. My 07 sedan just got UpRev'd last week. Runs beautifully!!

So, a little more info from this thread: http://panoramic-3d.ru/forums/tuner-d...technical.html

I opened the file in a hex editor and there were probably thousands of lines of code, so without prior knowledge of where anything is in that code, a lot of trial and error would be needed...

It looks to me like a bunch of the "tables" that the ECU uses might be stored pretty early on, there's some interesting patterns around the 37XX offset area where there's runs of values that contentiously get larger, but not by a fixed amount, and things like that.

I think it would help if we had a program that would let you graph the raw data given a certain offset range/#rows/#cols/bits-per-byte/etc... in a 3d type chart.
Just seems like being able to get a more visual look at the data might make it easier to find some of the tables

Judging by the other ECU's, most of the power modifications are actually done in the later part of the ROM image (like 0x60000 area). I may be able to narrow down the areas I think it would be at by looking at some other ECU's. Most of these ECU's use the same or similar CPU's, they just use their own brand-specific encryption I guess.

Anyone know what software/hardware is involved in dumping the ECU? My cousin is thinking about getting an osiris tune, and if I could get the hardware/software, I'd love to do a before/after dump of his car, as well as a dump of a factory 04 G35 Sedan AT that I have.

Getting all those files to compare would probably make things a lot easier.

Might be hard to get ahold of the required hardware/software if you're not an Osirus tuner though.

Another way to do it is explained pretty well in this link:



I know for our cars there's a cable called the blaZt for OBDII which we can use to hook up to the OBDII port. Then you might be able to use ECUFlash, ECUexplorer, or some other program to dump the image.

They say in their FAQ that the NSDII software won't flash anything to the ECU, but IDK if it will do a rom dump or not. Couldn't find that info anywhere on their site, so I sent them an email.

NDS II goes through the OBD-II port.

I have a newer ECU in hopes that I'll be able to go from the older "Maxima style" grey connector ecu to the newer black connector ecu.

I took apart the ECU to get ANY information that might possibly help out:



The info off the ECU is as follows:
It's from a 04 G35Sedan with AT
Outside label on the ECU reads:
Nissan
Hitachi, Ltc. Tokyo Japan

WA
MEC31-980 B1 3141

There's a QR code printed on the label that contains this information:
WAMEC31-980B10000WA341423710 AC0100155 (thank's QRDriod )
If you notice, the bold part is the "ECU number" that you can lookup on infiniti-techinfo.com except this particular one isn't in there for some reason

Inside the ECU, printed on the circuit board is:
31-980 in gold letters,
ge223471-a in white letters.

The chips, from left to right, top to bottom are labeled:

Motorola
mc38186dh
1
kkcz0246


l9302 - ad
b995c0312


l9302 - ad
b995c0312


789101a
a03(a1)
0310k323

The big one in the middle:


64f7055f40
rl 0306
bb02800


Then the last one:

l9762 - bc
b99140303




Hope this does some good
