Power Fc In A 25t Rs Four "s"

[wolverine]

Sorry for assuming you hadn't read the whole post.

If you read down further from the first post Andy gives a reason for doing it the first way but it is completely up to you.

Ah now I read it again it'll save me frying the ecu. Cheers

Auto sparky had the car today but suggests that there isn't a pin in the socket for pin 51. Anyone able to help with what pin to use in the socket?

Got the car back today and engine light is now out. Auto sparky fitted a terminal to pin 51 and followed wiring diagram for diode and resistor placement. Cheers. Car is a 1997 S1 RS4 auto converted to manual using a power fc for a r34 gt-t for future reference.

Yep, mine is pretty much exactly the same: 1997 S1 RS-Four V converted to manual by the previous owner, then I had the R34 GTt PowerFC with "secret squirrel tweak" done.

Did you have to do anything to get your ac to work? I think mine is ecu related but can't find a pin out for my factory loom

[GoldZilla]

Ah yeah, I do remember having issues with that, now that you mention it. The conversion was done a long time ago, so I can't remember (and don't actually remember being told) what was done to fix it.

I think when I had it done it was mid-summertime too, hence my requirement for working air-con.

Also, I see Duncan has replied in the PowerFC thread - his car and mine were both done at the same place.

Does anyone have the info on supplying tps signal to the attessa ecu to make the 4wd to work with the power fc? Mine has never worked since I've had the car. Have the pin 51 mod done and bled the 4wd system, pump primes and I'm not getting any lights in the dash.

I'm assuming it's the tps signal anyway

Heres some relevant info. You'll have to check whether the power fc outputs the voltage to the attesa.

If not then you may need to employ some electronics skills, ie, you could make a splitter for the TPS so it supplies voltage to both the power fc and attesa, however you would need a buffer circuit to ensure that there isnt a voltage drop caused by connecting the sensor to multiple devices.

Cheers. That's a good bit of info and helpful suggestion

Ok, so I have correct tps at attesa ecu. What's next? I can get the pump to run for approx 5 or so seconds with the bleed plug in the kick panel disconnected. However, it doesn't prime when ign is switched on. Could it be a faulty accumulator?

Great thread, just so that I'm in the the clear. I will be removing the NA engine and dropping a RB25NEO AWD from a Stagea into a R34GT-4.
I'm going to throw out he GT4 ecu and use a GTT ecu. To be able to retain the Attessa. I should split the TPS signal into two. One goes to the ECU and one goes to the ATTESSA.
I will be running a Link ECU is it any different to a Power FC in terms of the trick mentioned above?

Did you guys have to purchase a new wiring harness to be able to do this?

[KiwiRS4T]

Pretty sure the Link goes into the GTT case - you may need an auxiliary loom for the IAT sensor and maybe the Map sensor

Yes it's a plug in ECU. I was worried if it is possible to do the same as covered here for the PFC. I have a map sensor and IAT ready. They connect on an XS loom.

Hi guys, massive thread dig but need your advice. I have the power fc with the secret squirrel trick and want to confirm that the thrm should be reading 3.7v? Pic is of what mine is reading.
