What Ecu?

[dannyb]

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...

Even if it is a Mines' ECU, it means fk all as you can't do anything with it.

[Oddy man]

Ive a brand new Greddy emanage Ultimate (universal harness) floating around if you're interested.

Open to offers I guess, still in plastic/boxed

Ok so i cant tune the mines ecu?? or are they just to hard to play with?

Thanks but ive been thinking along the lines of a power fc with the h/c...

[lachlanw]

mines is untunable .

bar putting a nistune or something in it assuming its a standard ish ecu

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...

or slam a nistune in it

[bubba]

+1 for Nistune

Haltechs are great pieces of kit but not really suited to street cars.. I'm about to pull the e11v2 out of my wagon and replace it with a Nistune (mainly because it's auto and VCT isn't working properly)

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)

+1 for the Haltech Platinum

get one and youll never have to worry about your ecu again, throw another bazillion horsepower at it if you want

[KiwiRS4T]

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!).

[dannyb]

thanks for all your help guys i think im heading in the right direction ill speak to some tuners and pfc or haltech it is..

thanks again....

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...

[wolverine]

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)
