Hi all,

cant find from searching,

will a Nistuned ecu from a manual R34gtt adapt into a C34 RS4-S stag?

appart from obviously needing to be retuned is there anything different which would stop this from working?

would i need to separate the board or could i swap over the ecu itself?

thanks for any help.

glyn.

You should be ok as all the maps and settings you can see are the same however the issue of traction control and what Nistune does with it might cause some background issues.

The board can have the correct base image loaded onto it by Nistune or some of the dealers with desoldering gear but that will cost around $50-75 depending on how they are feeling.

i know its a different product but a link g4 sells for an R34gtt and they plug straight into a C34 RS4-S (they market this fact aswell)

so i reckon a nistune in this instance might work.

however these are marketed for the series 2 rb25det NEO engine wont work with pre neo engine

Talking to my tuner about this months ago. Nistune will work in a s1 if you convert to manual. You can use the neo ecu on a s1 & s2 rb25.

I haven't been game to try the auto r34 ecu in my auto s1. I read some threads from years ago where the car would start and drive but would eventually die

It will work BUT if you use the wrong base image you are never sure what the factory ecu is doing behind the scenes. So in the case of running an R34 GT-t image you will throw a trouble code due to the lack of traction control. You can switch the notification off but it may be doing something in the background.

My RS4S was a pain in the arse on throttle recovery. It took me a long time figure (it went past 2 tuners as well) to notice that the base image was an auto image. I had the board re-imaged and I wish this had been done 2 years earlier...if it had been done right in the first place it would have made the car nicer to drive day to day in traffic.

well im looking at a bord from a MANUAL R34 GTT NEO into a MANUAL SII Stgagea rs4s NEO

the compatibility should be fine but i dont know if theire is other things on the ecu cuch as the 4wd which may get disturbed.

Again

4WD is not an issue AFAIK, more a case of whether the ECU is correcting the commanded values to protect itself.

The commanded values within Nistune for an R34 GT-t/RS4/RS4S look identical but some tables are not visible within Nistune so it isn't always easy to know if the output from the ecu isn't altered.

Keep in mind Nistune is a work in progress.

It will be fine if you load up the right base image on the board whichever ECU.

It will probably be 99% fine as is...but it might give you a few niggling issues that $50 re-image will fix. Ask the guys at Nistune they are generally very helpful.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
