Often wondered how hard it would be for a tech minded person to simply copy a nismo or impul chip put it on a blank chip and do it that way much like copying an iso image of a movie or computer program.

It can, but that would put the stock ecu into limp mode, which would cause a knock on effect of loosing functionality. We needed a setup which retained all stock drivability without throwing any codes

Neither will any of the aftermarket ecu manufacturers, and the Emanage just isn't cutting it with so many of my customers wanting 300+kw. Looks like I need to do everything myself, so I am going to g

No-one will spend the time and money on development of a daughter board, but there is another simple option. Just get the Nismo flash off it's processor and dump it into a stock one. Theoretically the Consult 3 can do it, but I am yet to try.

Yeah fair enough.. was thinking tho if our problem is the oem ecu being kept happy, having something intercept the outgoing signal (to modify) and having a closed loop or oem signal returned would be the case in solving some of our problems (which I assumed a daughter board could be of benefit) literally something running the parameters of what the oem ecu should be seeing. Maps etc. (Almost like an safc or crome for honda? ) mind my ignorance

Bumping this thread as my M35 should be ready for tuning very soon.

Currently stock ECU with Emanage piggy backed making just over 240+kw on pump 98.

The car will soon, hopefully, still have the same mods / tune however the auto will be missing (manual yay!)

I assume error codes will appear due to no auto and i do wonder how drivable the car will be with said error codes if at all. If anything it will be an interesting day.

I'm still unsure what path to take to get the car tuned and running fine with the manual in place...

Thoughts?

I wondered how the blokes using Link units are travelling with their tuning.

Cheers

The going is slow with the Link at this stage, getting tuners off their arse can be difficult at the best of times. :P

The plugin loom is all finished and looks the goods, it was a lot more work than I thought though Beau.

Cheers for the info Scotty.

I'll let people know how i go starting the M35 once everything is bolted together. Hopefully the error codes wont prevent me driving it with the current set up.

Then I will have the luxury of more time to investigate a real tuning solution.

Has anyone looked at using an EMTRON? They're powerful and can control a heap of stuff, cams, quad DBW throttles and more. They obviously aren't cheap but are well priced for the performance etc they provide. It won't control the auto box but may be a good solution for the engine?

Also what makes the NISMO ECU better than the stock? I read before that you can ditch the fuel cut and rev cut, anything else?

No throttle delay/restriction.

Worth it; for that ALONE.

As in you wouldn't need the brake cut mod? Or something I've missed?

Brake cut mod is still useful, but the throttle response is much more aggressive and linear.

What you put in at the pedal; you receive instantly at the TB; not a version of it; some days/weeks later...

Ahhhh yea. Lots of DBW cars suffer similarly, you can normally get a little box that plugs in under the accelerator pedal and must alter the signal to ECU/TB. Helps heaps with that and has multiple settings as to how aggressive/sensitive you want it. I think it has an "economy" setting too that must do the opposite and make it less sensitive/aggressive.

The problem is; the controllers can't actually open the throttle from a standstill any faster than standard, so all you get is a weird, jerky oversensitive throttle when you're cruising, with a shiteload of lag off mark...

Considering the price of the ecu is twice what I bought my last stagea for, and you can't actually buy one due to some exclusivity complex they have, I decided to ignore that particular ecu brand. I needed around the clock factory support which even Haltech couldn't give me, infact I am still waiting for a call back from their support line.

Link gave us what we were looking for, a brand new Fury 6 cylinder specific ecu with direct wideband, cvt cam control and the ability to run our M35 electronic throttle in a cheaper package than the other leading brands. Unfortunately it's out of the budget of most Stagea owners, but for those pushing the boundaries with power it should be the best option available, and other than the MAP/IAT and flex sensors it will plug straight in with the patch loom. Finally a better ecu than the Fcon for standalone control.

Very impressive result for a first start and an untuned drive. Well done guys! Have you fully disconnected the standard ECU from Ricks car now?

No, the stock ecu must remain in place. Rick and I have set the Fury up to run in parallel with the stock ecu, which is still running the cams and throttle. Seems to work well with no errors at this stage. Still a long way to go before removing the stock ecu will be possible, most likely we would need to ditch the auto before going full standalone.

I'm quickly losing hope that my M35 will be drivable for the xmas break :(

More effort will be made to try and get it running with the 350z manual in place and just tricking the stock ECU that it's an auto box is in neutral...

I'll be there tomorrow afternoon so i will try and take some pictures as i didn't get a chance last weekend :)

I have a feeling once the chaos of xmas is over i'll be asking Scotty and Rick a tonne of questions :P

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
