Will A Manual Nistune/power Fc Work On A R34/stagea S2 With Auto?

[eXquiSit]

as per title

i am curious as to whether a chipped manual nistune ecu out of a r34 will work on a r34/stagea with the tiptronic auto

is the transmission control module seperate to the ecu?

there is conflicting information online thats all

thanks!

Ask on http://forum.nistune.com/ They'd have to both be type 4 boards, so a neo engined (S2?) stag.... IIRC you can load some auto ECU images onto some previously manual ECUs, but get specifics from the Nistune forum. They'll probably want the part number from the ECU.

As above the obvious place to ask is Nistune.

But to answer your question yes nistune will work.

[Ben C34]

I have a nistune ecu and id725 injectors, z32, walbro pump for sale very soon. Along with a few other things. Very little use.

Came out of s2 rwd auto stagea so identical to r34, and reasonable sure would be fine in a awd stagea, could ask Matt at Nistune if interested.

[eXquiSit]

interested in the setup ben, flick me a msg when youre ready to sell

ok, so what about pfc?

does a pfc for rb25 neo (r34 stagea s2) work with autos?

rwd only

[Ben C34]

Pm sent.

A power of is a no go, and I am biased toward Nistune but it is the nicer option, especially as now there is the flex fuel option available with it.

[eXquiSit]

oh why is pfc a no go?

Here's something to think about. Manual R34 ECU does not have the auto transmission CU built in to it. I suspect that they do not have the auto comms circuitry built in either. And of course, even if they DO have the circuitry, the comms between ECU and TCU only occurs INSIDE the ECU's case.

What I'm saying there is, I wouldn't assume that a manual R34 ECU will talk to the Stagea's TCU. It might, but I wouldn't count on it. I wouldn't even count on an auto R34's ECU to talk to the Stagea's TCU.

Per advice given above, definitely ask Nistune peeps (Matt direct or the forums).

[Ben C34]

Nah. If yours is an s2 rwd stagea just buy mine!

[KiwiRS4T]

Buy Ben's

Manual ECU even with the right Nistune chip won't work.

Power FC won't work with auto.

The R34 Auto ECU actually has 22 extra pins on it compared to the manual one.

If the manual ECU literally doesn't have these pins going to sensors and solenoids that the auto ECU needs, then,um, I can't see it working?

UNLESS the difference really is just on the plug, and the R34 manual LOOM doesn't have wires coming out of the other end of the plug.

I don't know. Never seen a manual ECU/loom But there's definitely extra pins in the workshop manual!

Nah. Not the point. The Stagea's auto would still be controlled by the TCU, which is a whole separate box on the other side of the car. So the missing pins on the R34 ECU not being connected to the tranny shouldn't be a problem.

What would be a problem, as I posted before, is that the R34 ECU expects the comms channel between ECU and TCU to be internal to itself, and therefore I expect that it doesn't have the capacity to talk to an external TCU. Keep in mind that there is a serial comms bus that runs around these cars (the Consult bus) and this is what the various CUs communicate with each other on. The R34 ECU is definitely able to talk to the ABS and TCS controllers out on the vehicle bus, I just don't know if it CAN (get the pun?) talk to an external TCU. It might.......but then it might not.

Oop.. for some reason I didn't read the thread properly and thought OP was trying to get a manual nistune working on an Auto R34, not a stagea, which seems to have a similar setup to a R34 N/A (seperate TCM)

You could just get an external TCU entirely, but lol don't.

Just put a manual in.

If it's out of the question, wait until it is part of the question.

As before, NISTune would know, but I wouldn't beleive them until I got your own, original, factory intended ECU to be NISTuned' or you could confirm 100% that the ECU you had was from an Auto Stagea.

nistune it is

i got a auto rwd stagea and was looking at options
