R32 Ecu Help Please

[liss]

HI We are in the last stages of getting our R32 lemon on the road

After 18 months and 2 mechanics and almost 10 grand later !!

The mechanic is struggling to get it tuned

It has a bigger turbo and a standard ECU

is this the problem ?

do I need to get an upgraded ECU?

This car has almost sent me broke

but its so close now we cant give up

Any advice would be appreciated

Our daughter got majorly ripped off when she bought the car

and we thought we would buy it from her to get her out of trouble

so we have no idea about skylines really.

Yes, look into Nistune. You can find cheaper second hand ECUs for sale (in the parts sales section).

Do you know what injectors and turbo it has?

[GeeDog]

You can add a Nistune daughterboard to your stock ECU, which makes it a tunable ECU http://www.nistune.com/equipment-products-type2.php. If your mechanic is trying to tune a stock ECU, find another mechanic.

Where do you live?

Hi

It has stock injectors

And I dont know what turbo but its twice the size as a stock one

Its the one that came with it

The mechanic isnt trying to tune the ECU

sorry I ment just running smooth

It went better with a new fuel pump

but he said its not getting enough octane ?

Does that mean I need a new ECU

or upgrade?

What does a daughter board do ?

This is a second hand ECU I have for It

the Auto electrician said the old one was burnt out

Thanks again

Check out the link provided to you by Geoff. A Nistune chip inside your current ecu will make that ecu tunable. Or if you want to spend another $2K you can get a Link or Haltech or other aftermarket ecu but the Nistune will work fine for much less dollars. Once you have a tunable ecu you can stick it on a dyno and it will show if you need bigger injectors, afm and better boost control...but the tuner should be able to tune within the capabilities of what you have now.

And where do you live? Find some local RB enthusiasts to come and have a look at your car and make (hopefully) helpfull suggestions!

You have a decision to make.

Both involve going to a different workshop that know what they are doing..

1 Return car to stock and drive it.

2 Spend a fair bit more money on a tuneable ecu[nistune], fuel pump, potentially injectors afm and clutch etc then dyno tuning and have a quicker car. Maybe. Depending on what turbo that is it might be a pig.

[Ben C34]

Also your breather and pcv setup is totally wrong. Which will cause you issues. Who did that? If it was the mechanic walk away now.

(The black hose on top of the cam covers going to the blue t piece then onto the inlet manifold)

Well picked, Ben.

Hi Wow

You guys are really helpful

Were not really after a faster car

just one that goes

Thanks Ben Ill check if its still like that on Monday

and I think the stock option is best for us

Could you tell me what else you see thats not stock?

We have no idea!

Most work was done at Barnes High Performance

Sunshine coast

He had it for 8 months

then gave up and sent it back

to our mechanic with an auto electrician he suggested to re wire the loom

Ill get some up to date photos on monday

maybe its different now ?

Thanks again

We are on the Sunny coast QLD

[Ben C34]

Going to stock is the most sensible, cheap and easiest option.

You already know the turbo is not stock.

Other non stock visible items are the turbo manifold (what the turbo bolts onto). The cheap ones tend to crack. They position the turbo very differently. This causes problems as you can't run the standard air box typically or the standard intake pipework. Cops will pick up on it quickly.

If you keep an eye on the forums, exhaust manifolds can be had for around 50.

The blue 90 degree bend and intercooler pipework also isn't standard. Not really a problem though depending on how good it is.

Happy to try and help if you need more info.

So today we decided just to bring her home

where we can try out some of your suggestions

Weve downloaded the workshop manual so we can

understand what we are doing somewhat

Heres the current state of the under bonnet

I took a video but its too big to go on and now she needs

more fuel so Ill do a shorter video of her running rough

What fuel should we be putting in 95 or 98 ?

I was mistaken when I said it had stock injectors

they are bigger too ! cant remember what size though

Thanks again

OOPs photos disappeared

[scotty nm35]

Atmo BOV won't be helping things, it needs to be plumbed back into the intake, but your intake is all silicone...

[Ben C34]

As a quick fix blocking off the bov would be helpful. Well need to be sorted properly though.

I'm busy at the moment, will look harder soon.v9deo will help

[liss]

The BOV is blocked up

I was told it was ok to be blocked

just wont get the noise ?

Is that right or will it be causing other problems ?

Would appreciate it Ben

Thanks

Let me know if you need to see specific parts of engine

I didnt really know what to take pics of

[Ben C34]

Having the bov blocked is better than having it venting to atmosphere, but still not as good as having it plumbed back correctly. It can cause issues of running very rich when changing gears, and will actually be louder with it blocked (and make you sound like a wanker, trust me)

The bolt blocking the blue hose on the front of the engine is poor, you can get little caps to do it properly.

The breather system really needs to be sorted, but to do that properly means a new inlet pipe.

So its either keep the turbo on that manifold and get a new inlet made, and potentially have the manifold cracking, or get a stock manifold and pipework, fixing bov and breather and cracking manifold in one go.

[Ben C34]

Also on the throttle body the silicon joiner only has one clamp on it. There should be 2. No way will it work like that once there's some boost in there.

[Ben C34]

You don't need to buy a clamp like what's on there, a normal hose clamp is perfectly fine.

Can you take a photo of the turbo from the back, and try to get a couple of the manifold.

And bigger injectors on a stock ecu is never going to work properly, unless you spend the money on a nistune.

Hi Ben

Heres a pic of the manifold and the back of the turbo

The fabrication was all done professionally

and the welding looks really good
