installed a power fc into r34 gtr and wont start.... as per my post last week....

spent a week checking wiring etc......etc...

any one know or had experience with the immobilizer unit in r34 gtrs before..

even how to bypass or hot wire it....

another guy in the uk gtr forum had the same problemb as mine and it was the immobilizer...he ended up using an r33 gtr power fc in his r34 gtr but found out later that it can be bypassed or reset....

cheers...

G'day Mark,

You may have already checked this, but have to disabled the boost control module through the handset ??

The PFC's are defaulted with the boost control module 'on'. But if you don't actually have a PFC boost solenoid conected, it won't let you start the car.

Have a read on the handset manual and make sure the boost control module function is turned off.

Cheers

hmmm i fitted one in mine and it started first go...the only problem i had was the engine check light comes on.....mark if you plug in the commander does it light up and come on air?I dont know about that jay...i didnt disable it on mine and it worked...although i have the boost controller i didnt hook it up and it still ran

have got all the setting correct in the power fc. etc etc...

the engine light goes out with or without the hand controller in....

my car has a mines ecu which is out of an r33 gtr with the crank angle wires swapped inside the ecu.. it runs fine.....

it must bypass the immobilizer somehow being earlier model ecu...

but put the r34 power fc in and no start.... all settings correct......

wish i knew how it controls the computer.(immobilizer)....

cheers...

On my car the PowerFC would only fail to start if the boost controller setting was incorrectly set to On.

yes we all know that....

its not so simple with r34 gtr... every setting in power fc is correct for running...

Hmmm mark do you have the original key for your car?I am just wondering if someone has fitted the earlier ecu it wouldnt have the facility for the body control module(of which you already know!)But hooking up a standard type(or power FC intended for the R34 with the facilitys for imobiliser wiring ect..)the transponder or lack of transponder will picked up via the BCM and send the cut signal to the R34 ECU...if you got the key look on the end and see the red tab...pry it out with a stanley blade and check if the transponder is present...

I know i am not really answering your questions but hope this helps :(

if u turn your car on so the radio and warning lights come on, does your fuel pump prime for the same lenght of time as it did with the stock ecu in??

coz i had this same problem coz the fuel pump would only prime for around 1 second and the car wouldnt start and any setting changes i made on the hand controller would not save when the ignition was turned off.

I had to get a new positive feed form the battery to the loom and it solved all the problems.

Hi

I would like to fit a power fc on my R34 GTR uk spec, but on uk cars there is no immobilizer fitted and it wouldn't start with the R34 GTR power fc.

In uk most tuners use a R33 GTR power fc with a special harness, but if possible I would prefer to use the R34 power fc if possible

Thanks

    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
    • After @Kinkstaah debacle, I'd never want to try and get it right 😛
    • The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY
