Hey my mechanic says he knows a bloke who can tune GTRs and Stageas without any piggy back.

He's cracked the factory ECU's and can access everything.

I haven't met him yet but it's pretty exciting, maybe won't have to drop 1K on a daughter board and install.

I wouldn't mind knowing how much more you can get out of the VQ25DET with factory afm, turbo and injectors.

Not interested in E85, considering going for the Hypergear G1.

Will post updates as I get along.

I bet he is talking about c34 stageas. As mentioning gtr and m35 in one sentence would make no sense as the ecus are not even slightly similar.

But great news if he has, but until i see it i am very very skeptical

No, he started on the R35 and has also done M35.

Played around on the circuit boards and analysed how they work.

Curious to know what software he uses.

Next question is pm35 or nm35. PM can be hacked using uprev software.

Not trying to shut down what has been said. But we have heard this so many times before and nothing ever comes of it.

The issue with the nm35 is that the ecu is nothing like any other nissan ecu.

Hopefully he is right though and another tuning option might be available.

Where is your mechanic located?

If he's telling the truth, he's about to get quite busy.

Is it Toshi? He mentioned basic reprogramming a few years back if there was enough interest.

I have heard of many attempts to hack the stock ecu, but I am yet to see anyone locally unlock it, I can't even get a decent uncorrupted copy of the stock rom, with that theoretically a hex programmer could work out the maps and perhaps adjust certain aspects of the tune. I'm just not holding my breath for a decent solution any time soon, even if he has managed to communicate with the processor.

My bet would be "a guy" is Toshi.

We were discussing him bringing over the software from Japan that would allow rewriting of the stock ECU in much the same way as UpRev can for the PM35's.

Cost was far too prohibitive at the time though. so perhaps there is another option that has been presented... or he has the software now due to requests from some deep-pocketed R35 owners?

Even though I don't own the 2.5t, I would still very much like to see a remap option become available and the results of a "real" tune.

So much history, so much Stagea love :wub:

If you need a stock ECU, let me know as I have one in bubble wrap here.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      So now doing the change and first time dealing with rb so little nervous giving engine power and potential for screwing it up When you align all marks and then remove crank bolt, timing move little I assume you can put the bolt back in once you have removed the pully to get timing to where you want?   here is pic of my both intake and exchust cam aligned, depending on angle you look they seem to be either aligned or a half tooth or so out. Any thoughts? Should you angle your face and look at each mark that way as if looking straight rather than from above as it can be misleading   <a href="https://ibb.co/ZpnhcvbF"><img src="https://i.ibb.co/HfWrGR9b/IMG-4447.jpg" alt="IMG-4447" border="0"></a> <a href="https://ibb.co/4wm2wn4q"><img src="https://i.ibb.co/JWBqWwr1/IMG-4445.jpg" alt="IMG-4445" border="0"></a>   https://ibb.co/ZpnhcvbF https://ibb.co/4wm2wn4q

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Unpeeling the Orange

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Ok so no 4cyl clutch... Yeah it is a factory manual. So if iam correct i need clutch and flywheel too? I can use something that suits something like R32 GTST?   EDIT: https://www.ebay.com/itm/224291042776 Is this ok?   EDIT2: i maybe forget to mention this(dk how important it is) but the trans will be behind RB25DET NEO(iam doing swap) It will be there for a little while. Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.
