So I've been talking to G-Zone through a couple of intermediaries in Japan about doing a flash for an NM35 ECU.

They can remove the throttle restriction and the speed cut, which is half way there. They're also going to provide a remap, however that depends on what is in the car.

For example, before they can do it they want to know if I've changed the air filter, front pipe, centre pipe, rear exhaust and a bigger intercooler. They also want to know what diameter the exhaust pipe is.

I should be getting the rest of the info soon. How many people would be interested in getting this done?

EDIT: Looks like cost will be around $500 plus shipping! (Well, 44000 yen) But apparently there is a big difference between 80 and 90mm exhausts, and I'm not sure what implication this has for tuning?

No idea why they think exhaust size difference btw 80 and 90 mm would matter. Sounds weird. Anyway I'm in. I have plenum spacer, dump pipe and full exhaust and upgraded intercooler. I would like throttle restriction removal, boost to 1.1 bar, speed cut doesn't bother me I'm not taking the car to a track and would like much improved fuel economy.

Well it sounds like they're prepared to do custom maps, so I'm sure you can get whatever you want. But it sounds like they want to get it just right, might even make getting an emanage redundant for me for a while :thumbsup:

I'm not going to get an e manage ever so I just want one decent tune with everything I want and I'm done. This is my family car so it's going to stay nice and easy to drive and with a bit more power and I'm happy.

I just want the throttle restriction and speed cut removed...of course this is dependant on whether this UPREV crap can do a remap for us or not.

Maybe up the red line to 7250...but I think the Emanage can do that already.

So GZONE is going to do a custom map for each car? Hope they don't get it mixed up...:whistling:

Ok so Mr Amino (the bloke from G-Zone) says removing the speed limiter is included, but removal of the throttle restriction is 15000-20000 yen. He also recommends having an external throttle installed?

Does anyone know what he'd mean by an external throttle? I'm dealing with a Japanese intermediary who doesn't understand cars, so I'm guessing its not necessarily exact...

So worst case scenario is 44000 yen for the flash and 20000 yen for the throttle restriction, so $720. Sounds like a win?

He might be referring to one of those throttle controllers that don't do much :P

I have seen a heel of a lot of M35's with them attached (sites and auctions mainly).

Don't really know what else he would mean, unless he means an aftermarket TB like a Mine's or Impul unit.

64,000Y + shipping + supply of ECU? hmmm, I think I'll try HKS first.

Would definitely be good to remove the restriction though :)

G-zone are good to deal with (comparatively) and take into account all the mods you tell them, but it is still an educated guess and you will need a piggyback of some kind to take full advantage of your mods.

Oh, and word of advice, don't ask them the same/similar question twice :blush::laugh:

EDIT: Having said that, if I hadn't already bought my Fcon harness, I would definitely be interested.

When you put it like that, I guess its around the same price as an emanage and harness, but with the emanage you can't remove the throttle restriction or speed cut, and you still have to pay for the tune.

Will the HKS eliminate either of these? My drama is no local tuner, but guess I could go for a road trip. Plus isn't the HKS really expensive? Like G-Zone + Emanage + Harness expensive?

im sort of interested. but shit how long do we go without an ECU.?

Well if there was a spare one theoretically we could all take turns sending it in one by one whilst we are driving around with the spare...LOL

But like Cam said...a estimated remap is never going to be as good as a real tune.

Richxz - If you are purely after economy and bit more power I really think you should just get an Emanage installed and tuned. It'll be marginally more expensive then the GZONE but economy wise should be alot better...

Gzone remap + shipping = ~$800

Emanage + harness = $600

Basic tune ~$250

Where are you getting emanage and harness for $600? Cheapest I've seen is $600 for the emanage (new), plus the harness for $100-150.

And doesn't that still leave the throttle restriction and speed cut? Or is no one worried about either?

True

Hopefully.

Price depends on where you buy one, but the harness was around the $400 mark (but IS plug in - no wire cutting) and F-con's used to go pretty cheap over here due to a) lack of tuners b) price of tune... but ever since I started looking, all the cheap Fcon Pro-V's have disappeared :( but figure around 1-1.3k plus tune I guess.

I will be trying out the Fcon iS as well as it is more a piggyback than a plug in standalone but can apparently control the variable timing... although we heard the same about the Vmanage! >_<

There is a chance that either unit may remove the restriction although there is only one way to find out!

I may yet end up with an Fcon iS and a G-Zone :rofl2:

If you can get this off the ground, I'd definitely be interested.

Maybe the owners of the spare ECU's would be interested in doing a rolling loan, with a rental fee thrown in, so no-one has to be without a car during the wait?

Rather than everyone buying an ECU then selling it, abit of money on the side to cover your inconvenience?:whistling:

Given the number of interested parties, you'd probably make more out of renting it out than selling it. Plus a warm fuzzy feeling inside from helping the Stagea community?

Just a thought.

Scott couldn't get it working with the variable valve timing?

I'm leaning towards going the G-Zone way unless I can find something that tells me that either the Emanage or the Fcon will remove the restrictions. If they can I won't need to. If they can't I'll upgrade later and piggy back them on.

I got mine from Ebay BNIB for $500 shipped + harness for $100. I could be out by $50 but it wasn't that much more.

Well Richxz made it sound like he values economy above all else. Getting rid of the throttle restriction isn't going to help that...

And speed cut....well unless you're tracking/dragging the car, are you really going to use that? :whistling:

Yeah well I'm after a bit of everything. If I valued economy above all else I'd lift my foot ;)

As for the speed cut, I guess it doesn't matter, I just object to having a limit. I'm weird like that.

Look into the eManage then, I believe that HKS have sold out of the Fcon VQ25det harness's and they are now a discontinued item. There is one on Yahoo though.

I don't think you'll be upset with the Gzone :thumbsup:

I always see that listing on YJ....are they having that much trouble selling a single harness?!?!?

    • You have found the problem. The wire from the switch to the HB is shorted to earth. Now you have to physically find it and replace it. It won't be the switch, although following the steps above (and yes, where you ask, that is the light switch on the RHS of the binnacle) will rule it out for sure. Or not, if perhaps the switch has melted. But there's no route to earth inside the switch, so I can't see how it would.
    • I did read your post, a few times actually.    Done. Followed this step. [Negative probe should be on the cars chassis. Positive on the wire.]   Did this partially.. now that im reading this over, i only unplugged the LED lights. [Start as said above by unplugging everything (unplug the lights, and switches.] When you are talking about the switch, you're talking about the knob thing on the right side in the drivers seat right? If so, i need to take that apart?  [Now at the switch, there is a wire from the fuse, to the switch, so out your positive on that terminal. It should read open circuit. If it reads something, especially a stupid low value, the short is somewhere between the fuse and the switch.] At this point are you referring to the connector by the headlights?  [If that's fine, now put the positive probe on the wire that goes to the headlight (at the switch plug). If it reads stupid low, the fault is from the switch, to the headlight.] Did this. I can confirm that the LED lights aren't the issue [Another quick test, is take the whole LED light setup from the left, and plug it into the right side, does it still blow the fuse? If you put the right hand side led light setup on the left hand side wiring, does the left hand side wiring now blow?  If the blowing fuse swaps from right to left doing this, your LED lights are the issue.]
    • Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?
    • After 23 years of owning a Skyline, finally had the latch go.  Followed this guide,  works like a dream again. Great Guide 👍
    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄
