i'm not sure if it'll work because the current tuning they have are in different octane term than ours.

But i could be wrong as i never read anything from the 350z guys using the 350z USA ECU.

PS> I'm guessing you are talking about the ECU not the Dash Computer?

Wouldn't make any sense to use the ECU. I'd say the US dash comp in order to get screen etc in engrish.

I have a US ecu in my 2003 sedan, part of the conversion from 8 speed to 5 speed auto. Type 1

It runs well, good fuel efficiency no pinging. Have not checked on a dyno though.

Need to also think about pollution control differences, my engine light is always on due to not having fuel vapor control. Eventually will find someone to turn it off.

Being 2003 model, only had to get the security number from Nissan. May be bigger issues with later models.

Hope this helps.

hi guys. Has anyone gotten any further with this?

I own a 2003 v35 350GT. I'm a noob in ECU management and interfacing. And would like your opinon/ suggetions for the questions below.

1. Are the ECU's for the M35, V35 and 350Z similar?

2. Are these ECU's interchangeble after tuning?

3. My ECU/ OBD currently talks Consult (or so i have been told). If i could change the ECU, would the OBD connector then talk in the standard OBDII ? (I would love this, as i could then use my android tab with the Torque App)

Any advice is appreciated.

What's the point?

Are you trying to tune, or get a replacement ecu?

Even within models there are many multiples of ECU part numbers, there are awd models, auto, manuals, etc. I don't see a lot of compatibility happening. The computers are physically the same for the vq35 models, and any model of that can have the program ripped, and sent to Uprev to decode and provide a tuneable file.

hmmm...thanks for that info mate.

the only question i have left is, what's the best way to display live Engine data while driving? I was looking for something like Torque or similar on Android.

Any specifics will be great.

hi Scott,

mate are you sure that a standard OBD EML327 cheapy from ebay would work on my 2003 Skyline V35 350GT ???

any specifics i need to look out for on the Torque App? only asking, coz i have tried a fair few times on my Samsung tab 3 with a ELM OBD Bluetooth thingy. I doesn't read the protocols and keeps going round in circles.

No idea, all I know is the 3.5L was able to keep being produced after 04 due to it being OBD2 compliant, unlike the VQ25. I assumed the standard OBD2 readers would work.

If they don't you are stuck with the usual Greddy touch or HKS OB link units, both of which work on the 2.5det. I have an OB link here I am trying to sell actually. Check it out.. ;)

    • I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else
    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
