What Ecu?


Recommended Posts

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.

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

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

Open to offers I guess, still in plastic/boxed

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

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...

+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)

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!).

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....

Really, Micah?

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)

    • 8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!
    • Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!  
    • So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
    • Yeah, so try to post images with extensions that the internet can handle, not HEIC files which only arstyphones can handle.
