VY SS Engine Lag... Myths...? or Truth...?

[corypelican]

Ok, I bought a 2004 VYII SS Ute recently that has done mainly highway k's all of its life.
'Apparently' this causes the computer to create a lag in the engine,
meaning that upon take-off and between gear changes it can take 1-2 seconds to get instant/full power...

Has anyone heard of this?

I was told, the solution can be as simple as unplugging the battery for 4 hours to reset the computer and then "drive it like you stole it" so that the computer sets itself for that style of driving...

Has anyone heard of that?

Look forward to hearing from people!

You can only do this if you have a can of compressed air

[singlecampshrod]

piston filters are probbaly the answer

Clean the flux capasitor problem solved.

mmm he might be fresh out of plutonium anyway.....

[WLDLS1]

its the lithaneium crystals. they dont mix with the melecular structure anymore once you highway drive them. these need to be replaced.

[RICECOOKER]

doesnt kryptonite reverse it?

[swanee]

Have you checked the jupiter rings lately? might need replacing aswell

[RICECOOKER]

dont forget to check the battery power on the continuem transfunctioner that usually takes power form the engine

[WLDLS1]

krtyptonite causes a plutonium reaction and forces the structure into a extra sensis herdy gerdy. thats not good.

[RICECOOKER]

dam now we are all fcuked

We could give you advice all day long but in reality this is a forum...just give this guy a call on 9555-555...he'll know what to do :)

[WLDLS1]

if a herdy gerdy is caused then taking off any battery leads is bad bad news.
then we will be well and truely f*cked up.

Real answer is a set of diff gears + Mafless tune.....then...and only then will it drive like you stole it :)

Shouldn't a simple disconnected battery wipe any habits the PCM has learnt

[corypelican]

F**K ME!
This thread has been so helpful!

I logged on this morning thinking I might have some knowledgeable answers to my questions... I was wrong...

Keep the problem solvers coming, there might be something worth trying amongst them... :goodjob:

[Firebug]

Welcome to LS1 mate, where genuine noobs will struggle to contribute with an older car. Most questions have been covered before so you'll be swarmed by the search button nazis, or you come up with something new and end up with a thread like this. A stupid question is the question that isn't asked IMO...

Having said that, I haven't heard of what you are talking about in the original post. But I'm no expert, but I'm sure there are plenty of them here... :rolleyes:

[macca33]

Hahaha - I reckon the banter is very refreshing!

Anyway, do a few searches for 'torque reduction,' 'sluggish performance' and the like.

In the end, as Markone2 stated, a tune, some diff gears and other mods, information on all of this can be found throughout the technical threads, will make a world of difference.

cheers

[TheRealMadMax]

You could start by reseting the PCM (Computer). It is a simple process of warming her up, removing a fuse, replacing and then letting it relearn idle, followed by various opinions on 'drive it like you stole it'.

Search "Reseting PCM"

You will find heaps of info.

Also, give the girl a service, new filters, oil, plugs maybe, etc.

If no luck with the above, a tune should be able to fix your drama.

[WOMBIE]

To the OP for a very minimal outlay why not go a mail order tune from "Oztrack" and see if that solves the 'lag' issue between gears and take off.Go to the sponsored section of the forum and click the banner,have a read up and then email the man.....couldn't hurt :)

[corypelican]

Hope this does the trick!

[feistl]

Hey mate,

There is some truth behind this... many cars ECUs tend to "learn" the way you drive. So if your always going slow etc, they change early. If you drive really fast, they tend to change gears later....

Drive it hard for a few days, and the ECU will adapt. Disconnecting the batteries will reset the ECU as well... just make sure you've got the radio pin :)

[Vulture]

Just arrived!

Oh dear. Was there something wrong with the leads on it? Sad to say, I don't think you'll achieve much with the above. As Markone2 has said, get a mafless tune and it'll be sorted. Doubtful it needs any new bits and pieces like leads etc!

[SirNemesis]

- MSD leads


First mistake...

:rofl::rofl::rofl:

[thumpa]

if anything, go hurricane leads...being a sparky these leads are a direct short from end to end, no resistance what so ever where as stock leads have got a resistance reading in them

i used hurricane leads for 18months and got a new set just for sh!ts and giggles -- checked the old set and was still perfect

mate my advice...its a car u got -- u dont know its history -- plugs, leads, oil, filter and a PCM reset first day you get it, before you think about flux capacitors (they only break the piggy bank anyways)

Mate to be honest you answered your own question in your heading.

ITS ALL A MYTH.

[NuffNuff]

A ballist kit on the velocitator will make a generous improvement, be sure not to install it on the deceleratrix or you won't be going anywhere.

[SS Enforcer]

As someone suggested before just do a pcm reset and run your car on 98 fuel, 98 fuel will be the cheapest performance mod you can do for you car. A new air filter, leads and service wont do it any harm either.

The computer in your car will have stored the long term fuel trims and this over time may cause some loss of performance in some instances therefore resetting your pcm you will remedy that issue.

Then read this forum for about a month before you spend another dollar on your car and learn about what you really have and what mods will be of a benifit to you.

Someboday had to tell him...... :)

How do you reset the PCM?

The reason I feel stupid, is cause all the threads I have read about doing this are full of people asking the same question I just asked.
And the typical answer being, "Search this Forum"

My step dad fell for this when we first got the VY SS in 03.
He swore black and blue that it was true
Funnily enough, there was no mention of it with our previous VT
Must be a holden technician's inside joke

[redvxr8clubby]

I personally don't think using say 98 octane in a VY SS with factory tune will do anything. I believe they are tuned for 91 and that's it. HSV may recommend 95 or higher octane (95 is recomendation for my VX Clubby, so that's what I use). If on the other hand you get a tune, go by what the tuner recommends, if it is tuned for 98 at least you should get benefit from it.

Well your wrong the ls1 and it's derivatives have 2 timing tables in it in standard trim. They have an upper and a lower one and will happily run on the upper timing table when using 98 ron fuel. Running on std 91 fuel it will revert to the lower table a lot of the time.

Download a trial version of Efilive and have a look at the std holden tunes at www.Holdencrazy.com and you will see what I mean.

cheers

[Mad4Monaros]

Easiest way to fix your lag problem is to remove the drivers seat. You will notice a small bottle of "Instant horsepower" underneath it. Remove the bottle and replace it. It seems like your current one has run out.

Problem solved. :jester:

That is true to a point but a bit exaggerated. PCM resets are a waste of time IMO as it only takes the PCM about 10min of mixed driving to revert back to the way the fuel trims were anyway. As for the adaptive spark. Fill with 98 and give it some shit. It doesn't take all that long to recover if you work the engine a bit. But that is dependant on how low you got it in the first place. If you do piss farting around driving it will take a long time and if you were to only drive like that, then yes a Reset will get it back up instantly.

I agree with you Macca just run 98 in it and give it some stick for a while but the question gets asked and a pcm reset is pretty simply done. I still stand by my statement regarding 98 fuel being the cheapest and best value for money performance mod for your car if it's available.

cheers

what ever you do DONT PULL THE RED 10 AMP FUSE IN THE FUSE BOX UNDER THE BONNET. if you do this the bonnet will stay up causing more lag and drag.

[RICECOOKER]

what ever you do DONT PULL THE RED 10 AMP FUSE IN THE FUSE BOX UNDER THE BONNET. if you do this the bonnet will stay up causing more lag and drag.

if that happens be sure to fold it back and pull the yellow 5 amp fuse, this will help to make it see through within about 5 minutes, but if you pull the blue 15 amp it may speed it up a bit

[WLDLS1]

if that happens be sure to fold it back and pull the yellow 5 amp fuse, this will help to make it see through within about 5 minutes, but if you pull the blue 15 amp it may speed it up a bit

now you will confuse him. there are 3 x 15 amp fuses. does he pull the top one first then then bottom one then the middle or the bottom then the top then the middle or the middle then the top then the bottom or dont do the bottom one just the top one followed by the yellow then the red. that might work. problem is if you do them wrong you will get more lag.

you can bypass the whole situation by adding an extra piston gasket to each piston then topping up the throttle body oil with an extra 300ml of 85w 140

yeah but you then have the problem of thickness of gasket. to thin = lag.
to thick = lag. i didnt think of the throttle body oil. that could help you know.
synthetic or mineral.?

[RICECOOKER]

mineral of coarse as for the gaskets they have to be precisly 7.879mm any other and you get MAJOR LAG

[WLDLS1]

hmm. major lag. i think general lag would be better. at least it will roll ok once your foot is into it. would still lag though. this is a tuff one thats for sure.

[corypelican]

Ok, I have now changed the plugs and leads.
New air and oil filters and reset the PCM.
Still has lag...

I think the next step is to have a chat with power torque about getting some headers and a maffless.

Thanks for all your input though.

[Angelo_XLR8]

hmm interesting, one thing that i belive nobody has suggested is to check that you are pressing the correct pedal, if you are launching with the brake you will experience some pretty serious lag

also, i belive turining your key to ACC will help as it triggers a special Acceleration Mode

[VXSS346]

You'll always have some 'lag' in these cars, its Holden's progressive :vpo: throttle.

A tune/exhaust/intake will dramatically reduce it, but it will always be there to some extent.

I'd say a throttle body change might fix it, but not sure.

Cheers :)

[WLDLS1]

from all the info you have given i would say start looking towards the vortec motion of the turbulator. located near the throttle body. as said before if the lithainium crystles dont mix with the melecular structure inside the turbulator then lag will occur. the turbulator is radio active and requires all crystles to align for continues lag free performance. always wear protective gloves when handling the turbulator. static from your body will cause mayhem with the crystles thus losing the vortec motion need to get rid of lag. always remove the red 10 amp fuse before you remove the turbulator but do the fuse sequence first or the crystles will turn to water. we dont want that coz then we will never get rid of the lag. changing plugs and leads without aligning the crystles in the turbulator only enhances the lag effect. it causes the crystles to grow into blobbs leaving no room for mixing. mixing is vital in this procedure.
hope this helps.:)
