Ever wondered how big an ECU was...?

The file I have is just 1mb of binary. For a very complex machine, the file is kinda small I thought....

When you're not making pretty pictures, you can cram a LOT in to 1mb. Im actually surprised it is that big.

Looking forward to hearing of your success with Uprev :cheers:

A bit of a pictorial wrap up of the first round of the Nulon Nationals at SMSP. Held on a wet skid pan, it's a Motorsport event that pits 9 forum based car clubs against each other in club level Motor

And here is some in car footage of the day, showing the wheel work required for such tight courses! Sorry for my fat melon being all over the pics

Stagea's paint looks bloody good Alex. Nice to see some more pics from the Stagea meet. Scrolled down for more, only to be greeted with the red crusty that fouls up this thread

Well, today I dumped the ECU with the UPREV software and cable. 3 and a bit hours of waiting! Oh well. its done now. I have emailed it off to Abbey Motorsports in the UK. They are going to tell me if I can use the uprev software, which I am almost certain I can, and give me something able to be tuned and flashed!

Forgive my n00bishness but could something like this be used to dump a VQ25det Nismo ECU and then flash it onto a standard VQ25det ECU? Sharing the increasingly rare awesomeness with us all? I know our ECU is different but if we were just basically copying the settings from one ECU to another?

Well not exactly. The Japanese, places like G-Zone, can remap the VQ25DET ECU. Not a direct swap of the Nismo, but probably better because it's tailored a bit more.

Not entirely true that statement.

The Nismo is not an off the shelf ECU tune but it is tuned on each vehicle that the Nismo ECU is fitted. Removing most of the low RPM throttle restriction and improving response all the way through the rev range.

you thought wrong :P

thats why there are no part numbers for the ECU, they are unique to each car. however AFAIK they are done with the factory options so we mostly have those as other brands.

I bet no Nismo ECU is tuned for a car with a big fat intake???

As far as I can see, the problem with any of these pre-programmed ECUs is they can't be optimised for our cars which are all a bit different. In some way they have to be "best fit". If only some enterprising person over here would learn how to hack the damm thing & offer customised tuning. Otherwise we continue to tinker around the edges without getting right inside.

At the moment I don't think the volume is there for the time required to hack it. Can't see anyone putting in all the time and effort to tune maybe 20 cars in Australia that would want it done. This is comparing it against S13 and the likes where they would do more than that amount in a week.

Remember that some people tune for economy and performance, I suspect that a lot of people that buy an M35 for reliability and purpose would consider getting it tuned to improve economy too. There's more and more of these things kicking around Adelaide (and just about every one I see is modified), so I can't imagine how many are in the Eastern states!

The way I see it you guys have these options-

A) Go to the Russians. They might be crazy enough to pay for someone to do all the work (on the other side of the world they're probably sayin: Австралийцы достаточно безумен, чтобы сделать это )

B) Get G-Zone or who ever to licence their technology and some workshop in Aus buy the set up off them.

C) Deal with what you got, because I don't think anyone in Aus is going to crack it.

Edit

D) Motec. forgot about that.....

Thoughts?

I reckon someone will at some point.

I have a spare ECU that I can send out and had a place in mind down here (they create racing ECU's and are in Bayswater I think), but I can't remember their name to contact them :(

A good mate of mine is one of the 2 guys that are Nistune and I asked him a while ago about cracking it and it's not worth their time at the moment as the market is too small for the time needed compared to all the other models they have on the go.

Its not only the market, but Nistune haven't moved into anything with a CAN Bus electronics.

Spoke with him again. It's because the newer stuff is flash based so totally different to what they sell now, here and world wide. So it's an all new R & D for it. He said its something they will look at in the future but not any time soon.

They are very busy with the current Nistune gear. They have done an awesome job making tuning affordable for the cars that are currently supported. And keep in mind that this is a 2 man show.

So because a few of us m35 wankers need something it becomes out of their league? Your most welcome to crack if your all so capable!!!

And let's not rubbish a business for not yet looking into something we want in low volume. I was simply letting you guys know the outcome from me asking them about it

So stop the rubbish talk, we aren't children!

      V37 Alarm settings and what the buttons do.

      By HYBRID VL · Posted

      I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models?

      I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again

      Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!

      curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.

      Rear suspension upgrades

      By Dose Pipe Sutututu · Posted

      S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
