Hi guys.

Seen some pretty nice manual conversion write ups but I fail to find appropriate information when it comes to plugging in a powerFC.

My ER34 as I've just found out after purchasing a powerfc in fact was an automatic conversion, causing problems with HICAS, aircon MIL etc.

Does anyone know how to convert it 100% for the powerfc to plug in as normal into a manual R34 or the changes required?

Cheers

The ER34 PowerFC is the same as the stock ecu, it just expects the normal sensors to work and be present

if there are sensors not working or out of range etc the engine check light will remain on

you can see what sensors are toast by looking at ETC, SENSOR SW CHECK on the hand controller

any sensor that is toast will be highlighted in a black background

Hi Paul

Thanks for the reply. Even my tuner is stumped by the HICAS, TCS and aircon. I presume the Tps (THR black background int he pfc) diverts or relies on a signal or output from the shift control unit? I have the service manual but when I read the wiring diagram I look like :) <-- this. So i really cant find if this control unit between the fusebox and the door edge is actually between the normal signals coming to and going out of the ECU

If anyones interested I can upload the wiring diagram to check it out.

It should be fairly simple, does the car run fine? with the PFC?

Hi URAS

yes mate the car drives perfectly no idle hunts, smooth acceleration (still the standard PFC map) even when you poke it a bit knock levels under 30, cold starts jsut as easy as warm. Mods are simple just a pod filter and 3" turbo back exhaust, only boosted to 10psi. The only things that I know of that DONT work is the TCS cannot be toggled on or off. its simply off. and the a/c compressor. the a/c console functions perfectly and is even rekognised as being turned on and off in the sw/sensor check on the PFC.

cheers

Hey guys,

I didn't want to start a new thread and hopefully this one was just lost and not an unknown resolution. Something else I've found is that a NEO AFC throttle sensor reads fine 0-100% and both the PFC and Impul ECU drive fine. just have these problems with the PFC.

cheers

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
