As the topic says guys, I drive an auto r34 gt-t and I am about to order the TD06 - 20g turbo for my car.

Though I am having doubts whether the turbo will be running at its full potential since i wont be able to get a power fc to tune my car to adapt to the new changes since i was told by several that power fcs are not available for the auto r34 gt-t. So my options for stand alone ECUS are pretty bleak and I can only turn to piggy backs.

Anybody out there who can give me advice on what computer i can get for my car so i can tune my car to adapt to all my mods?

Also my stock ECU wont let me boost more than 14psi. When i get the turbo i would like to run about 15psi but i dont know how to over-ride this.

So whats available for me guys?

I will appreciate any valuable advice.

Good luck.

Will be watching with interest. 666DAN uses a Greddy emanage without the ignition harness. I've heard of a couple of others doing the same. I wonder what boost he's running...

I know of another with an uprated turbo and emanage was only running 12 psi though. Got about 230 rwkw's from memory.

BassJunky seems to be going sick on his car since he got it so I wouldn't be surpised to see him posting something soon :)

Apart from that the standard ECU appears to be tunable. Powerplay are working on it as we speak. They have done a couple of R34 GTR's and will be doing a test mule 34 before you can get them to do yours though. That's if you can beat me out of the way first.

Have you done all the rest too?

ps I've heard that r34 injectors flow less than r33 ones so they will need to upgraded if you can find a way to push 15 psi through it. Dunno about fuel pump but don't be surprised.

Hi Abo Bob,

So all these people that you refer to drive an automatic skyline right?

So you also drive an auto r34 gt-t? If thats your car on the avtar its a very nice car.

Can you tell me what your plans are?

It would be nice to have a mentor as I dont know much about cars you see.

I just know what im going to get as i have friends who know some what about modifying cars as they have walke dtheir talk, but I would feel much more reassured to have someone who also drives an auto r34 gt-t having the same plans as i do.

Im really interested in what you said about powerplay working on the stock ecu of the r34.

Have you any idea when they will accomplish the job?

I dont have much mods at all but i iwll list them and what i plan to get very soon:

Present: Full exhaust, Apexi High flow flat panel filter, blitz dd bov (RICE), Blitz LM FMIC, Bleed valve winded up to 13psi. Also have a apexi pod filter on the side but dont know whether im going to put it on or not.

*Note: the thing i have noticed about when using a bleed valve to boost up my psi and having it at 13psi is that when it over boosts me up at about 2nd gear my car cuts out and i lose power (the ecu wont let the car boost more than 14psi), so i am going to set it at about 10psi to be safe so it wont over boost thus cutting my power out because when im doing about 100km and then it over boosts it cuts me down to 70 - 80 km.

And this is the reason why I need some after market ECU to let me over ride this function.

Anyway back to my plans.

Future: Trust TD06 - 20g turbo kit with manifold , external wastegate etc

Bigger injectors (Dont know what im after yet though but i think i will need them)

Bigger fuel pump

Possibly cams

Apexi AVC-R BC

Oil cooler

AFM ECU (HELP NEEDED HERE!!!)

So what have you dont to your car Abo?

Whats your plans?

Please update me on powerplay

And any other news you get about afm ECUs for the r34 gt-t automatic.

Cheers

Working on something else at the moment but will definitely keep you informed. I'm going overseas next week and need new tyres asap so my mod money will be a little while coming.

I am yet to get a FMIC but following is my plan:

FMIC

Springs/shocks maybe Nismo S-Tune coilovers

fuel pump

malpassi regulator

ecu remap or piggy back that i'm working on now.

1 way diff

injectors probably 550cc nismo

turbo was thinking 2535 but am now reconsidering.

I've done already:

nismo panel filter (I don't think pods are necessary)

CES split dump/front pipe

fujitsubo cat back.

AVC-R

18" rims but they don't count haha.

R33/R34 stock ECUs are tunable but require a daughterboard and emulator (which is what I'm gathering PowerPlay would be doing)

Theres a lot of stuff for sale on GRID.co.jp to do this

Basically the stock boost cut can be changed in the standard ECU as well as making ignition, fuel maps etc tunable.

An example in some software I'm writiing applies to Skylines, 300ZX, Silvias etc

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
