Educated Guess At The Final Tune Results

[XKLABA]

You should be running BCPR7ES, not -11 which are 1.1mm but without it are 0.8mm, you want 0.7 or 0.8mm gap

I use Denso Iridium Racing plugs in a 24 heat range which is 8 in NGK

If you get those coils you have to set the dwell correctly or they won't work as they should. Which means you need the password for the ecu.

not sure the bloke here could handle the computer / ECU work ?

Once he touches it my warranty is gone, that is if they will give me the password, I think it will turn into a shit fight

[Hadouken]

Save yourself the headache and go get a set of feeler gauges and check your plugs. It is hands down the easiest thing to do to pull spark plugs out. As long as you don't hulk them back in you will be sweet

Tried something a little different to see what happens before I go to my mechanic on Monday.

Wound it up slowly in 2nd, when it was between 6000 and 7000rpm it just went flat, sometimes after the flat spot, you could go past 7k and it would pick up again. Did this a few times with similar results, it did not happen at the exact revs but near enough.

In neutral at about 5500rpm it would would make a quiet, blop blop blop sound, rev it up and it would die a little between 6k and 7k a few tinny pop pop pops, and then rev freely to limiter @ 8500rpm

Did I mention I hate farken cars

[Hadouken]

Sounds tune related and not spark blowing out.

Don't know if your mechanic will be able to help with that.

Just to be clear, by winding it up slowly you mean driving off boost correct?

[Nismo 3.2ish]

No, I mean slowly driving up to those revs with boost instead of hitting it hard.

When I was hitting it , it would back fire a little and splutter , when I did it slowly to the same revs it just went flat, like it died ?

The neutral thing was strange as I took it to @ 5500 and held it there and got that other result, could not feel that when driving too/at those revs

A couple of times in neutral it revved to the limiter but not freely, it would hesitate a little as it built the revs up

I was just trying to get as much info as I could to give to whoever I can get to fix it, There is a bloke n Port Macquarie I might call on Monday after I see what, if anything my bloke here can do

f**k that makes me mad pete...

CRD ... Worst customer service ever

They have one job, tune the car properly and advise on parts to make it reliable

... Sorry that's 2 jobs

Hi Joey, pretty frustrating and the distance does not help as I have to fly both ways, over $700 each time I leave the car there, adds up after a while

Does this problem sound like the coils or the tune.

He wants me to change the plugs again and I think he already knows they will fark up again, well that is if they are stuffed up now. Guess it will give him an idea what could be wrong, but it seems pointless as it has happened twice, after the first tune and after the touch up last week ?

If the plugs are sooting up quickly I would think it is a tune problem, too rich. If this is the case is there a " better plug " to try, I do not want to have the plugs changed knowing they will go tits up without trying a different plug or something.

They have asked me to drop the car off again and leave it there longer so they can go over it and find the water and tune/spark/whatever problem, so I guess it is back to the shop , there goes another $700 and hope for the best

I will get the starter motor fix ASAP, if you were a mechanic and had just finished an expensive build and started the car and had this noise like it was still engaged once the motor had started, what would you do????? Me I would fix it!

[JH32]

if the car's going back to CRD for an extended period to fix the tune issue, perhaps it's not a bad idea to get them to do the starter while it's there, even if it does cost you more. Saves the hassles of stuffing around with the local bloke, then you can tell CRD that you don't want the car back until it's purring.

Sound to me like they are milking you mate

Get it to someone else to run it up that can tell you exactly what is going on

Next time your there ask to see their mechanics licence lol

that helps mate, two great minds think alike, $1600 for a 98 tune was a good place to start , well $9k over quotes wasn't a bad start ,haha

Any thoughts on using a certain plug ??

I am having a problem thinking about going back to them, I thought I was done and dusted

[XKLABA]

Get one out and tell us what it is, even use feeler gauge to get gap

Should be a BCPR7ES with a 0.8/0.7mm gap

It sound to me like the spark is getting drowned which is why you are getting black smoke out the exhaust, if you can see it in the rear veiw mirror then there is alot of it meaning there is way to much fuel

[Ben C34]

A plug change won't fix it.

I'd like to think that they won't charge you for the tune fix up.

Surely Australian consumer law gives some protection, their service should be fit for the purpose .

Seeing as you've spent a tone of money there they really should sort it out asap.

You could have bought a brand new safer performance car for the money sunk into this one, so it should be sweet with no issues.

More like a shit load of soot , not smoke as such.

I am crook atm , I will take it to a mechanic so I have a professional opinion, it should be interesting to hear what they say.

But I will have them check the plugs and if they are stuffed or not the ones you recommend I will have them follow you instructions , thanks

Yeah Ben, 20/20 hindsight is great and I wish I had it. Being suborn can be expensive, but I usually end up with what I want

I will see how this all pans out and what I want to do about it, but before I could do anything I would have to give them a chance to fix it. They asked me to bring the car back in and give them some time to check it out and fix the problem

The other option is to go to a different shop and get them to sort it out, not sure about the locked ECU or if they can just scrap the old tune and just do a newbie ?

[XKLABA]

I am very doubtful a cahnge of plugs will fix your issues, just what to know what they out in there as that is realisticly what you should have

My best guess is it is tuned to rich

[Nismo 3.2ish]

No doubt it is rich and from my experience and what you have said they tune rich all the time. This is why they want me to change the plugs

The plug change will give me an indication where the issue is.

[Hadouken]

Too rich is bad and stupid. Gives us the indication they don't know what they are doing.

[Nismo 3.2ish]

That makes 2 of us, I am stuffed if I know what I am doing anymore.

Why do they tune rich, is there some short time advantage until the plugs foul up ?
