Hi All,
Just had my 75K service done and a Trans and Engine Oil flush. Have noticed a definite drop in performance, nothing tragic, but the pantsometer reckons I'm missing a quite a few KW across the range and a fair bit of agility.
I'm pretty bummed about this, because up until now , my baby has been so friggin awesome it still takes me by surprise sometimes (I find myself inside other peoples boots a lot when I try to overtake). One of my most recent cars was an XR6 Turbo which had nothing on this IMO.
I'm hoping it's just something they've done to wipe ECU mappings and it just needs to be driven for a while in the homicidal manner to which it had become accustomed, and it will relearn/come good , but I'm really nervous that they have changed something (Oil types, ECU flash.. I dunno?) and I'll never work out what it is again :eeek:
I suppose I'm only worried because frankly I've always found this car literally just too good to be true (which can often mean something is amiss/waiting to explode) and now I'm afraid they've "fixed" something
Anybody else have this experience?
Cheers,
Gold

Why are you so upset about his claim? It's not hard to beat an average Joe at the casual traffic light grand prix. Launch is the key, so by watching the other set of lights go red, stalling up to 1,500rpm and stomping it to the ground on green you can get a whole car length in front by 15km/h.

You need to let the car realise that you want to flog it. My car is in grandma mode all the time and it seems really slow and awful if I suddenly decide to give it some throttle. I believe it comes from the reluctance to shift down (flat boot at 45kmh will not drop down from fourth gear even in to second in D mode.) When I really get into it though and give it about 45 minutes worth of tiptronic madness up a mountain, then perform the same 45kmh foot drop, I suddenly find myself in second gear and accelerating rapidly instead of just sitting at 2,000rpm wasting a lot of power / fuel / fun through the torque converter.

In short; let the car relearn your driving style and you should be back to normal.

Cam could be right and it's just that the Invecs needs to relearn your driving style. But I'm thinking that wouldn't make any difference in tippy mode, so in tippy mode how does it compare to how it went before the service?

I course I have a manual & I do all my own servicing so I've never noticed any loss of performance after a service, if anything it goes better!

Mate not having a dig at you, just a few outrageous claims that have been on here in cheek!

But specifically I would be changing the 02, plugs and fuel filter as a start before anything. I also have found magna's to fun a bit richer after a reset while learning.

Heh, no worries, don't mind me, I'm just time poor, hence the extended forum vacation.
By changing 02 I assume you mean the Air filter?(is K&N,and does need cleaning). Thing is I had no trouble with the consumables before the service,so why now?
Run richer while learning.... that's interesting ,I could check that with the OBD log,might do
Cheers

Find out what oil they put in your engine. If the viscosity is too high it might be messing with the mivec unit on the front of your cam gears. I have heard this could be a theoretical problem on late model mivec systems.

Mine went through a funny period too a while back. It dropped economy and performance. I looked everywhere but couldn't find anything. I did all the normal stuff including cleaning MAF. Eventually it seemed to come back again. Funny thing that.

You didn't get the timing belt changed did you? (not a standard 75k item though)

Maybe they adjusted the handbrake cable during the service and it's dragging a bit?

If it's a series one they may have done an ecu flash..(.seem to recall there was an update the dealers did.)

Girls.......

I have read only but a few of the posts containing the usual verbal diarrhea that seems to to be the base of every 380 thread made of late so here goes

Yes the 380 is a great car
Yes, this is 380 section of the forum

NO YOU DONT NEED TO GET ONTO THE BLOODY 380 BAND WAGON everytime someone brings something up about one of these cars

In short, if you are not answering the question from the OP, piss off and move on, if you are, then thanks for assisting

THE NEXT THREAD WHICH GOES ON ABOUT HOW GOOD THESE CARS ARE will result in bannings WITHOUT the infraction system being used, is this clear as mud???????

So in summary, if you can not assist the OP then GTFO

If you do not like the 380, no need to state this in the 380 section, just dont buy one, if you feel the need to defend the car, do so via PM, E-Mail or Fistycuffs, just keep it off these forums.....

edit: Where is my post, well I have cleaned up the trash in this thread yet again....

So some info has been lost. To summarise;
- it is likely the ECU has been reset, so
- the transmission has lost it's saved mappings,
- other learned info such as timing advance / retard has also been lost,
- ECU may have been reflashed with new firmware if your car was an early model,
- oil may have been replaced with a higher viscosity than before, or
- the handbrake may have been adjusted incorrectly.

Where is OP anyway? :oopssign:

G'day... still here......but kinda have to agree with Madmagma, the whole "which car is better" argument bores me almost immediately, and had nothing to do with my topic , so I was staying out of it (tried to head it off, but failed).

Unfortunately I've been away from the forums for quite a while and forgot what an insane congflaguration such casual throw away remarks can illicit :doh:, rest assured I won't make any comparisons again.

Meanwhile... back at the ranch..... I may have found the source of my minor performance loss. Now... This is just my observations, totally unsubstantiated by any measuring device other than my trusty and infallible pantsometer! but when they serviced my car, I found my custom airbox ducting on the floor of the car. When I asked what happened , they said it was loose in the airbox (can't understand this , as I can't even remove the glue from either surface with force, but I find it hard to believe they ripped them off, so....). These two ducts point the airflow from the lower (mod) and upper (galant) Air intakes directly at my K&N, and prevent cross flow turbulence between the two airstreams.

I didn't think it would make a huge difference, so I left them off until last night, when I was cleaning the K&N and thought I might as well glue them back in anyway (added a custom heat sheild between the trans/engine and the intake system as well for good measure). I took it for a test drive, and straight away noticed the difference after it blew a WRX off at the lights ... <oops> :eek2:.. WAIT! , WAIT! I MEAN.... It went really well again!, there was no WRX, it was a Semi trailer, or it could even have been a kid in a billy cart ......I'm not sure :shifty:
Point is , it seems to make a difference.
Just an informational post, anybody interested can see the details off the ducting in my old post on "Blow by Blow intake mod", take it or leave it :thumbsup:

Might still look into some of the suggestions here anyway re: handbrake and oil
Cheers guys, sorry to have been so inflammatory

Panadol is good for 'inflamation'. Good info cheers. Got any pics?

Actually Ibuprofen would be more effective as an anti-inflammatory than paracetemol ; have now taken the precaution of adding this to all future posts as a preventative measure:

Ah yes. It all comes back to me now. Almost 12 months ago. Cheeers.
I was fiddling around with the intake today and I still cant figure why the cutout opening supplying air to the intake is so small. Searching for my dremel bit to open it up. If you checkout a Falcon setup the airflow opening almost mirrors the intake.

The Falcons actually have a scoop behind the grill which forces the air up into the the intake. I thought about trying something similar for the 380 but eventually lost interest in the idea. I also enlarged that hole in front of the intake so it stops just short of the clips holding it down. I figured it couldnt hurt getting more air in there and although it made me feel good, I would be lying if I said I could notice a difference.

Pfftt! Not at all - woke the place up lol

Great to know your performance mods are so effective - you actually thought something was wrong - no better test!

Having a look at your ducts again and thinking about the bottom duct. I haven't done anything with the bottom reasonator. Might be time to heat some plastic...

..... directly at my K&N, ......



You forgot to tell us you've got a KN filter.

Forget everything else.

Ditch it, put in a stock filter, clean the MAF sensor, disconnect the battery, reconnect.

Then continue trouble free motoring.

Yawn.

The fact that many, many users on here use the K&N and report better throttle pickup (even though torque & peak power stay unchanged) suggests that they don't care what you think about this, no matter how many times you continually post the same thing.

+ 1 for a yawn however.....this thread is about offering advice to a member who has lost power after a service. So, he had a K&N before the service and was happy with the performance. He gets the service where they have changed certain things but retained the K&N & now the car has lost power. Please explain how ditching a part which hasnt been touched will help solve the problem????

Yawn.

Instead of continually trolling, why don't you stay on topic and maybe post what you think his problem is?

Instead of just simply insulting members maybe contribute something factual.

I'm not insulting you. I'm simply saying what a lot of other users have re-iterated over and over again - we are sick of hearing about your opinions on this one issue.
If you want a definition of trolling, try someone who takes every opportunity, on every thread where the K&N is mentioned, to criticise it.

Anyways, glad you got it sorted rjgoldsmith. Do you know why they were accessing the airbox in the first place if you have a K&N installed? Do you have the K&N sticker on the airbox that effectively says "leave me alone"?

WTF is wrong with the people on this forum, you all claim to be adults but are nothing more than spoilt little f*cking kids

I will say this one more time, IF YOU CAN NOT STAY ON TOPIC AN NOT BICKER dont bother posting as I WILL PERM BAN THE NEXT SERIES OF PEOPLE who do this crap, i am for one sick and tired of cleaning this crap up. Play nice or **** off......I dont know how much more clear I can put this.

Blackstar, the guy had his issue fixed, while I agree with you about K&N filters, well on Magna's anyway, there was no need to comment

Flyboy, your comments were not needed or wanted. There is a report post feature, you now, that little safety triangle down the bottom of each post, next time use that or STFU

I think this is simple really, perhaps I will get my 5yr old to write this so you kids can understand
