R34 Gtr Tuning Help

[aleaspeed]

Hi,

Have the following ugrades:

-K&N Induction

-3 1/2" catback Exhaust

-Apexi PFC D Jetro

-GT2871R Turbos

-Turbosmart Boost Controller (set to 1.2 bar)

The power is not as good as I hoped it to be. Any advice?

Have just purchased a Nismo fuel pump and 600cc Injectors hoping that'll make a difference.

Also need help tuning the PFC since am running it on the base map. 

HELP!

You're going to need:

- Exhaust Gas temp gauge

- Wideband O2

- Datalogit

- Dyno time..

or pay Unigroup to tune it for around $500~$1000

Base map and upping the boost = trouble

You were doing full power runs on the stock map? oh dear...

But ye - as above, you need those items to kick off. Datalogit isn't essential, but very handy.

What tuning experience do you have?

Thanks for the tip.. Trouble is living in Africa proves to be abit of a hassle when it comes to ordering aftermarket parts. Many ppl don't ship here.

As for tuning experience, I have a tuning shop here and have produced fairly good results with evos & stis.

Had a Supra RZ just before I got the GTR and that was a breeze to extract big power out of. The GTR seems to need alot more to make serious power.

Yeah a better designed cylinder head and an extra half litre capacity will do that.

Have you done any head work?

Also, why 600cc injectors with 2871 turbos? That combo should be good for over 700hp so 600cc injectors aren't going to do it justice.

How much power did you make at 1.2 bar?

I suggest for safety, pull like 3~5 degrees of timing off rows P15 -> P20 before you blow something running that much boost.

Guilt-Toy confirm what equipment I'll require for the distance tune and what you charge for it?

Was thinking of purchasing the wideband O2 sensor kit from Innovate motorsport and the pfc datalogit.

Suggestions anyone?

Dan.. I guess ur right about the Supra.

Haven't gotten any head work done yet. The thought of dismantling that head worries me abit.

As for the 600cc injectors, was looking for drop-in replacements by Nismo and that's the best I could get. The others were sard and tomei but needed modifications or new fuel rails which I didn't want to venture into at this time. Placed an order with greenline 2 weeks ago and still awaiting goodies to arrive.

What kind of power should I expect with the setup I plan to run? Was hoping for something in the region of 600.

The absence of dynos in this city make it difficult to makeout exact horsepower. But the fact that I manage to keep ahead of the Evos & Stis, I assume I should be in the region of 400

I hope you are talking 400kw? Standard turbos can do 400hp almost. That setup will see you to 600hp at the wheels but make sure your tune and fuel system are both up to scratch as these two items will let you down if you're not careful. 600cc injectors are a tiny bit small for the turbos so monitor your afrs closely and make sure you don't push it past their capability.

Make sure the wideband device you purchase is a good one, and has 0-5v afr output so we can connect it to Datalogit.

the price is about $350 usd to tune this car. if you fly me to your country I can bring everything with me. the datalogit and the wideband sensor needed to tune your car. I am in Georgia in Eastern Europe so it will not cost too much to fly you there. Maybe you can find other cars that need tuning as well and we can work something out.

I normally charge $300 - $500 usd for a tune. Remote or not.
