^+1, that would be fantastic.

If you don't want to host it, PM me and I'll throw it up on a host.

Not much to update at the moment. I'm waiting on a harness adapter to test.

^yes, an adaptor for the ecu. That would install in about 10 mins. New wiring harness would be hours upon endless hours.

Is SurraTT the one making the adapter?

Has anyone tried to talk to Matt Brown about the hex dumps and the best way to make heads or tails of them? In case you guys don't know who he is, he's the man behind NIStune and is practically a genius in my book. If you're unaware of NIStune, its basically a Godsend for the earlier Nissan cars like the Z31 & Z32 300ZX, VE30DE, SR20, KA24, RB25, RB20, RB30, VH45, TB42, etc. I know there aren't currently any offerings for any VQ35 cars with NIStune, but he may be able to help in deciphering the maps.

^Yes, SurraTT is doing it.

Sounds like someone needs to contact Matt Brown about some rom dumps.
SurraTT had a couple, but they were stupid encrypted ones from the Osiris

Trying to get this test harness done soon as possible. Ive got a TON of other car stuff going on right now!


Once the harness is made ill make a new thread on here to keep track of whats going on and how well it works with the early gauge and such.

It's exactly why it didnt work....

I believe he crossed the mass air flow and a ground... the car would start over but not start.

I have EVERY single possible pin out inside the box.... just havent had a chance to send it out to Richard.

ohh me.


More details on what you done?


Possible NATS does work with the older G and newer ecu?

Did you check engine light come on when the ign was turned on? (usually is on for few sec)

I didn't do much to be honest, I just spent hours on the computer that the tech's use at Infiniti to find out all the pin-outs and ecu diagrams. I have an emanage blue and I wanted to be able to hook this up to the ecu patch harness so that I can at the very least just control fuel but when I noticed that I was experimenting with a 1,000.00 ecu I quit the minute I saw the engine didn't start and then I had to reset the ecu to get it to crank.

I honestly gave up on that idea quickly.

but here is a picture of the harness.
