ok thinking about changing my ecu so ive done some snooping on my rs260 and what i found was that on my ecu theres a garantee plaque on it from mines (number 5063) and also a sticker with the barcode from Hitachi ltd with a nismo sticker below that. Does that meen its a nismo ecu and mines are the tuners.. My camera doesnt like me today so ill get photos up when i can..

Also on another note checked my turbos and they have garrett stamped on the side my question is are the stock turbos garrett or are they after market..

I know they are noob questions but any help would be great...

Get a Power FC, I will slap you if you put anything but that on a 260RS. Haha

:(

I mean don't get me wrong, I have a GReddy EManage Ultimate on my 400hp JZZ20 Soarer, and they are really good. But for an RB26, it will pay to spend a tiny bit of extra coin and get a Power FC tuned for it, PLUS 99%, if not 100% of dyno tuners out there will know exactly how to tune a Power FC on an RB26. You can pick up brand new ones for about $1000 delivered, brand new, from Japan.

Here's the link: Perfect Run Japan - Power FC (Clicky Clicky!)

And this is the part number you will need: 414BN029

As for your Garrett Turbos, yes, they are stock items. Garrett make the turbos for the RB26. GT2530 if I remember correctly. My 1JZ turbos were made by Garrett but they had Toyota CT12A cast onto the compressor housing, but I think the steel label on them said Garrett.

I use a PFC in my rb26-powered car, and to be honest, I'm not very impressed. Do yourself a favour and get a Haltech Platinum computer: I'll be switching from PFC to Haltech shortly: much better tune available with the Haltech...

Really? Last I checked the tuner has a bigger input than the ECU.

(not knocking Haltech Platinum as they are a great bit of kit)

So long as you get a tunable ecu the most important factor is the tuner. Find the best tuner in town and discuss your ecu choice with him (or her) before you buy and install it. The tuner in Sydney whose fame has spread to Auckland is Yavuz at Unigroup Engineering.

Best bang for buck is Nistune but if you want better I would choose the Link (or ViPec). Support and new developments are better for them than for Pfc. The main advantage of the PFC is that there are a lot of tuners around who can use them (how well is another matter!).

Agreed, the tuner should be the biggest factor in the equation (assuming that the computer suits the car in the first place).

My car is going in to Unigroup next week for a PowerFC retune and clutch change, and Yavuz is an incredibly down-to-earth guy who won't bullsh!t to you about what your car needs. He's got the backing of quite a few people here in Sydney, and justifiably so!

yes indeed: I have had the car tuned twice: first by SAS, then by Matt Spry (420AWHP), and I STILL have the annoying "power FC syndrome": the car misses at around 2500-3000rpm when under light to medium throttle... I'm a huge fan of the haltech. That said, I have seen excellent results with the Nistune computer as well.

End of the day, I'll be turfing the PFC: I'll miss the hand controller moulded into the console, but I'm more interested in having a car that runs perfectly (or as near as possible with an aftermarket ecu)...

EDIT: I should probably also mention that I'm leaning towards switching to MAP sensor rather than afm, so the Haltech is ideal...

Ahh, the ol' RB26 PFC misfire.

I believe it is an earthing issue but it can be a pain to run down.

The Nistune is the best bet today for a streetable car.

(I had a slight miss on one car around 2500-3000rpm due to the relative difference in the mapped AFR vs closed loop.....the step was too big to provide a smooth transition, leaning out that section of the map ironed it out totally)

      Left & Right Window Regulators for 2013 Skyline V36 Coupe

      Both windows operate normally while the engine is running but start to sag as soon as I switch off.  Does anyone know of reasonably priced replacements or other brands that will fit?

      Actually PowerFC is probably the easiest to get basic data from, it comes with a hand controller and display so you don't need to remember to pack a laptop every time you drive. It also has a PC based viewing/logging option if required. Nissan used consult on these because back in the mid 80s, ODB was just a glint in a standard's body's eyes.  They switched to OBD shape around 2000 (my 2001 Cima had OBD shaped but not OBD compliant port) With the standard ECU there is a cable and software available to give basic data too, I think it is called Nissan Data Scan or s

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      Given by the sheer number of questions about offset, absolutely not. If you had the information formatted this way: Space from R34 GTT hub to outer arch = 100mm Space from R34 GTT inner hub to nearest suspension arm = 90mm. (making this up) Buying a wheel that was advertised as Enkei RPZ5 Diameter 18in Width 9 Distance to arch = 84mm Distance to suspension arm = 76mm 100% of people would know instantly if it fits. They would absolutely also know instantly how close it fits too, and no questions would need to be asked. You would know you would have 16mm from the guard and 14mm from the suspension arm.

      Ah ok, for example for the apexi ecu I heard that it's pretty limited with the information it can give you. Also not sure why Nissan used the consult port over the obd2, what the idea there was.

      Diagnosing with and without is mostly the same. You need to know, as Duncan asked, and what conditions. Car hot, cold, idling, driving, if while driving what rpms, is when you're varying, or is it when held constant.   From there it's understanding what can be causing it. Starting with pretending all of the sensors are correct. Which means if it's going rich, why would it be thinking more air is going in than it is, and under what conditions. So things like if only when under boost, it could be be a loose intake piping joint. It's just understanding the system, and understanding when/how the problem occurs, and then if it's only occuring in specific scenarios, what can be causing it.   ECU specifically, if it's aftermarket, it'll have software you can use, for the Skylines on factory ECU, there is Nissan Consult you can use. Most ECUs have a way to get data from them.
