Tune Disappointment :(

[Trozzle]

Kinda happy that my ECU comes blank lol....even though they could just dump a base map onto it and tune WOT, it's more incentive to do the job properly!

[rev210]

As people have said dyno's are a relative tuning tool. The peice of paper is fit to wipe your ass with if it has no translation to on road /track improvements.

Noticed you have standard cast iron dump pipes, they don't help.

The cams are set to what? Basically the intake 2 deg adv & exhaust 6 deg retard ? If not thats roughly where they need to be with standard cams.

14psi on standard turbo's with some kms on them is asking for it. I wouldn't do that. You can make decent power 220 -230rwkw with 10 -12 psi and the turbo's are less likely to go pop. If you are bothered by the power then buy bigger new turbos.

When and not if they do go pop you have a good chance of needing a motor rebuild , as many have discovered over time.

Again, better to chase something about the cars driving characteristics than a sheet of paper with a number on it.

Bit of interesting information for you mate

I'm running 280rwkw, factory GTR dumps no problems (16psi or so)

There are plenty of cars running 330rwkw through R33 dumps also (GT-SS turbo/Garrett -9s)

I do believe the car I've purchased - and picking up tomorrow hopefully - has stock R33 GTR dumps and makes a lazy 350rwkw on some hybrid turbos

I wouldn't necessarily class them as a major issue at all.

100% agree with borrowed time RE: turbos - 1bar IMO is too much. Be happy with 12psi, and let the motor live

Not sure what they are set too

I agree 14PSI is too much on these turbos and will be getting a boost controller soon

Im not chasing numbers on a piece of paper, i just knew that the car is capable of so much more and after driving the car foe awhile you can feel all he is done is push the torque lower and leave the top end with nothing, IMO he did a half assed job and im not happy with it and in the end thats what matters

Dumps will be changed once i get -9s next yr.

i would like to only run 12psi looks like i need that boost controller

How are you getting 14psi without a boost controller, cause if that is just off the spring (odd) a controller wont let you drop it .

You just have to pull the restrictor out on RB26's

Hmm.. no argument that you can shove power through them if you have extra to spare, admittedly my only experience is with power 'increases' in swapping them and looking at the turbo flange overlaps on the 5 or 6 pair I've swapped ,they all were pretty wonky casts, not to mention the tight bends the stockers have as a design feature/flaw.

If the few I had were anything to go by then you could assume that the factory casting process isn't really precise, so there might be better and worse casts out there?

I heard the R34 dumps weren't so bad...

Just a quick update,

Went back to the same tuner after being reassured that he would check it and see if there was anything wrong...after a day i get a phone call saying my power fc is screwed...so stock ecu back in

Dropped car off at a different workshop this morning to see if they can make any sense of it...get a phone call around lunch time saying the power fc is working perfectly and with a preliminary tune is making around the 250kW at all four wheels mark with more fine tuning to come and thats with boost wound back to 12PSI

Will report back with the end result

This has been a huge learning experiance for me and now have found the workshop ill be with forever

Thanks again for everyones input

[MrStabby]

Great news! Let us know who the tuner is when you get it back and have confirmed that you're happy with it.

[skylinecouple]

I've said it before and I'll say it again, learn the art of tuning your own car. Get a wideband for $350 from the States and go for it. Read, learn adjust then read some more and so on. You'll pick it up. Sure, get a good tuner to do the basics on setup but fine tune yourself. The results will amaze you. Power Fc wins in the home tuner sector but I am just looking at the Vipec or something similar with self tuning mode and better control over the whole process.

[Rolls]

Good call skylinecouple, I'm in the process of getting my tuned checked over by the manafacturers of nistune and learning how to do it in the process, only way to have complete confidence it has been done properly is to do it yourself, or be present during the entire tuning process and understand what they are doing.

[Randon_I_Am]

+1

That's the path I've gone down.

To the extent that i can change maps and tune my car from my sterio...

But I'm always there in the car while it's on the dyno and learning what the professional tuner is doing.

UPDATE

Picked up my GTR this afternoon and we ended up making 260Kw at all four on 14PSI, but with my new boost controller in we have it set on 12PSI with the option of 8,10 and 14PSI

All i can say is that it feels great and drives brilliantly the guys at Pulse racing have done a great job and their service and help they gave me through all of this was impeccable.

Now its time to just enjoy the car

hehe after reading throught this im glad to hear its all good now man. what a bunch of idiots whoever you took it to before though, hey?

..

"shit boss i dunno whats wrong with it"

"just say his ECU is f*cked he wont know"

"sweet, now can i get back to watching porn?"

hahaha thanks mate

yea felt like that!!!

ohwell live and learn i guess

Can I suggest that everyone avoids this workshop from now on? Pretty massive difference, it isn't like they made the same power and one was just slightly smoother and had better fuel economy, thats 60 bloody kw and 190 knock!

Incompetence comes to mind, can I suggest that nobody ever goes to this workshop for anything?

whups double post

Problem being, you can't name the workshop publicly

the wonders of private messaging.

[Trozzle]

Exactly it, but then you need people to ask you for the name etc.
