R34Gtt Nistune -> Rs4S

[GH05T]

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.

Best bet email nistune. I would say yes it will work. But it's your money and time

[GH05T]

dude is selling one second hand, might email them anyway see what they recon

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.

best option would be to de-solder it from the 34 ecu and have it installed into yours

hmmm... I'm in the exact same boat too.
Looking forward to your findings Glyn, that's if I try it out before you do.

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

Mine is SII manual anyway

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.

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.

aaah, thanks

[pipster11]

34 gtt and s2 stage a both use the type 4 board so the board will fit but as said it's probably better off putting it in the stagea ecu for all the subtle things

[wolverine]

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.
