Hey guys,

I'm just wondering who amongst all of you has had their car tuned by Advan Performace in Silverwater.

Reason I'm asking is after they tuned my car I have been experiencing high levels of engine knock, high as in the hundreds according to the Power FC hand controller, and my ignition timing is at 42 degrees which I have been told is extremely high. I have had the engine compression tested, result was 145 across all cylinders, car doesn't blow any smoke or make any strange noises. The drive home Advan the knock level did not exceed 22, then the following day I think it went up to 120 something, highest reading from the hand controller was 200 and something, I'm hoping it's a faulty knock sensor or something. Hasn't seemed to damage the engine at all.

So I'm just trying to find out if anyone else has had a problem with their tuning. I'm thinking of taking it to CRD to be retuned.

Any suggestions or input is appreciated

Thanks

With a power curve like that.

I would be taking it back and asking for a retune, or alternatively something might be wrong with the car, part not 100% or something.

The curve is all over the place. Not what a good tune should look like

I knew I should've taken it to SAS in the first place. One of the guys from SAS told me that Advan don't even have a proper tuner working for them, said they specialise in "bling" only.

Any idea what part might not be 100% to 'cause that sloppy power curve?

that is f**king horrible!

I street tuned my own car and the curve is 100% better then that crap - i hired a dyno the week after to get a couple of power readings and this was one of the runs.. totally different.

How much did the tune cost you ? I cant believe they let a car out like that.

the tune looks fine

the top higher power run is the "after" dyno plot

the lower one is the "before" dyno plot

if its knocking a bit more than 60 then you just need to spend a few minutes getting accustomed with knocking and how to correct it. the pfc faq (in my sig) will tell you in great detail how to work with knocking and debug it correctly.

read that and it will help you sort out the knocking

er, i wouldnt be doing any fixing yourself at all (regardless of how easy it is after reading the faq)

id be taking it back and telling them its knocking and make them fix it

Look at the power surge between 130 - 145 - that looks like something that would happen with rich and retard not with a full power Fc tune.

I would like to see the ignition map and fuel maps of this tune.. there must be a reason why its doing that.. if its not the tuners fault then there must be something wrong with something there.

before getting carried away with taking it somewhere else, or accc etc. just go back to advan and tell them your concerns... at least give them a chance to help you out. I'm sure if they did make a mistake, or possibly something changed on your car since the tune they will be happy to take a look and at least diagnose the problem (if there is one) for you.

^^^ I agree with that... if they screwed up go back to em and see what they have to say about... but 43 degrees of timing is faily high isn't it? standard is like 15 or something like that.. according to the sticker on the bonnet...

Some workshops are really good to there customers - i know if it was Turbotechnics in newcastle they would put the car back on the dyno and double check it and fix it if they can for free.

I hear lots of good storys about advan so i wouldnt be suprised if they do that for you too.

Hey mate,

I had my car tuned by SAS a month or so ago and they did a great job. Good blokes, especially Rodney real helpful, i would recomend them to anyone they are straight talkers...

i wouldnt be to concerned what the guys from one workshop said about another .

your chart looks ok , not great but ok and you said it drove home fine

i think something else is wrong , lots of timing advance will cause detonation and something is f**kign that uo

Yes, even if you approach the ACCC for help, they will always tell you to go back and seek a resolution with the service providors.

Lets not jump the gun with suggestions of involving the ACCC, thats ridiculous

its really not a big deal, 42deg isnt much of a concern

im up near 50deg on my tune and it rawks

if its just knocking in one or two spots

use the pfc faq to help work out where in the maps it is and

then goto advan and ask them to kindly sort it out

every tune knocks differenelty on the street with the owner dirving it compared to being on a dyno in a simulation. happens and just needs a quick touch up once its out of the simulator and in the real world

As Paul said, knock over 60 is something to be concerned about. 120-200 would sound like someone pouring a bucket of gravel under your bonnet.

If you heard abnormal sounds, it's probably knock and should be dealt with. If you didn't hear it, it's probably a bad sensor.

If it IS knock, it could be a caused by a bunch of things, some of which are not the tuner's fault, but most of which probably are. Try some fresh gas before you get too worried.

I wouldn't hesitate to fix it myself, but I like that sort of thing. If you paid someone to do a job, give 'em a crack at fixing it.

Good luck!

Dan

Cost me $3000 for the Power FC, Z32 air-flow meter and the tune which means I paid over $1000 for a dodgy tune. I'll get someone to check out the sensor.

I don't think I'll go back there, they seemed kind of hostile towards me.

I have a friend who highly recommends Powertune in Fairfield, and from what I have read on these forums, they're not so good, but my friend assures me they can do just as good a job as Unique Autosports.

Anyone on here had experiences with them?

Thanks for all the help.

    • Yep, yeah would need to do the flywheel although the 6 bolt NA clutch can handle a 20de if just wants to replace the stocker.
    • No it's fine. Heat sleeve is a thing. With oil running through it it is unlikely. Engine off heat soak can be a thing though. There is no way that you have a leak through the hose. That has pressure behind it and any small hole will turn into a large one in very short order. It is so much more likely to be leaking from the connection.
    • Really? That's piss weak. I didn't know they hobbled the shitboxen that badly. OK. So probs need to buy a flywheel too. But that's not too bad.
    • Hi all. I already posted some newbie-ish questions here and there but this will be my first "big" post. Last summer I went and fulfilled a kind of childhood wish, because I just thought I needed this experience in my life no matter what. The car I bought is a mildly modded 1995 BCNR33 Vspec. It was repainted to a metallic orange color all around and it had all windows reseated. Not so well done black respray in the trunk and a metallic black in the engine bay. From outside it looks very nice except for a minor paint error on the roof and the rear spats needing new adhesive tape. The inside is pretty clean and no broken plastics, missing or faded buttons. Even the adjustable mirrors and trunk antenna work like a charm. Despite a moderately long list of issues I don't (yet) regret buying this car. Most mechanical problems are just due to age, like worn rubbers here and there. The underside sadly has lots of corrosion, especially to the back. It looks like it either has been driven in the winter for a while or it lived near the saltwater in Japan, the rust is nothing terrible but it'll require to be looked after. Mostly panel gaps and all the mounted components underneath are a bit crusty, but I don't think anywhere has progressed so badly that there's going to be holes. Front right jacking rail is crushed and needs some care so it doesn't develop into a rust crater at some point. Worst part is definitely the strut towers. I thought they looked fine but after taking off the strut bar I noticed that it actually started bulging up on the passenger side. Probably would have passed on the car or negotiated down by some thousand Euros more if I had noticed this before buying, but here we are. Trunk area also has signs that there was a water leak to the interior once but nothing too crazy, I guess lots of Skylines had this at some point. As for the list of (known) issues, I'll try to make this compact. I hope the coloring is self explanatory. Mechanical: -Various busted or soon-to-be busted rubber bushings and ball joints. Will replace ball joints with OEM or better and bushings with polyurethane where possible. -Shaking steering wheel at above 80kph -downshift from 5th to 4th is a bit crunchy unless I rev-match, might just try to renew the shifter assembly, but it's not a priority issue -tailshaft centre bearing could use a replacement, is it worth going 1-piece tailshaft as it doesn't look too fresh all around? Chassis: -underbody corrosion on many spots and in hollow spaces, needs to be treated -corrosion on many bolts, hoses, lines, suspension components, subframes, will be treated when replacing of the bushings is needed as time goes on -strut tower top panels and some of the surrounding panels are rusty, so needs fixing. Will look into doing this with a buddy in the winter, otherwise bite the bullet and pay a professional -driver side door is misaligned to the body and needs to go a slight bit more inwards -both door windows are misaligned and have an airgap where the window meets the door at the B pillar -The Aerocatch latches for the bonnet have locks but no keys, need new keys. -driver side door window is kind of gritty and could use a polish -damaged jacking rails and front frame rails, from people lifting the car the wrong way, might have this fixed by a bodyshop Electrical: -Nismo tachometer is just bouncing and displaying nonsense, supposedly worked fine when the stock ECU was still in the car -An old Greddy boost controller sits on the dash which will be removed as it servers no purpose anymore. -a led segment rpm gauge is on the steering column, will probably also be (re-)moved once the Nismo tacho is working correctly -there was an attempt to make the sound system better by the previous owner but it was just inducing noise all the time, ripped out the amp and filters in the back, no music for now -trunk antenna goes up as long as the radio is on regardless of the mode, I want it to only rise if I choose Radio specifically or per switch -3rd brake light is a bit dimmer than the taillights but everything was converted to LEDs so mabye now it just seems dimmer? -reverse light flickers, have to test if that behavior changes when I fiddle with the gear stick. Hope I can get around changing the switch. -Left side taillight, blinker section has minor water intake and is humid after washing. Other side has a hole in it, probably for that exact reason. I'll probably reseal them entirely and plug the holes. Engine: -minor coolant drips on one or the other hose -rear turbo leaks oil onto the exhaust making the car essentially undriveable due to fire hazard -Oil filter relocation kit has an oil drip at the Dash lines, will probably make a new connection there and tighten real good and pray -throttle body assembly is slightly stuck for the first throttle pedal input after sitting for a while I'm always open to suggestions and advice from more experienced people, I'm sure half of this list is easily dealt with and just requires some time and effort to sort out properly. Once I have some proper pictures of the car I will post some in this thread, I just have to remember to take some more once I get the chance to. Will post updates when I have news on anything, I want to try to keep this thread as kind of a logbook as well. Ultimately my goal for this car is to just enjoy it. An engine rebuild is probably going to happen sometime as well, because it is old after all. It will never be fully new again, I am just not that rich. But I want it to look good, work well and not rot away while I drive it. I'm probably gonna spend a lot of money on this journey, hopefully not an unreasonable amount.
    • Hi all. So one of my major issues at the moment is my rear turbo leaking oil on the exhaust (and the general area). I presumed it was the rock hard super old drain hose, which it was not. So now I am in the midst of removing the rear turbo to get access to the banjo bolt that goes into the turbo oil feed. As one of the previous owners accidentally? tore off the OEM oil feed hardline that reaches behind the turbo, they ran braided lines directly to the turbo, presumably PTFE. Now, regardless if the line has rubber or teflon inside, is it just generally a bad idea to do this? I imagine these lines get quite hot being between the engine, turbo core and exhaust manifold. I suppose it's not too far fetched to think the line may even have melted. I'd love to hear your opinions on this as as the replacement OEM hardline piece is 130 per unit. And cutting open the currently mounted line to see inside will mean I just have to get a replacement either way. So far I am hoping maybe the bolt just loosened or (god forbid) they forgot one of the crush washers.
