Turbo Lag

[shendaikary]

I have just reasently got an mn Triton glx-r auto
but i think it has a fault
it has the worst turbo lag i have ever experanced in years.
it is most noticable around town during rolling starts, i have found that if i lift off the power that the engine instantly goes to idle, as the trany disconects in auto mode, this causes a loss in boost so when i accelerate again there is a 3 second wait for the power to return.

i have been to the dealer were they pluged it into the machine and give it the all ok
but they have also told me that it is the only auto mn they have driven so have nothing to compair with
here is hoping that it is a fault with mine and not the series

has anybody else experanced anything like this with their MY10 triton

[gregned]

mine seems ok but yours may be the same as mine I don't drive it hard but the 3 secont wait for power doesn't seem right unless its from a stand still

[shendaikary]

im not driving it hard either
it plays up most notably when trying to negoatiat roundabouts
when moving along at about 15-25kph then apply mild-mid throtal to go
then after 2-3 seconds (aprox 2000rpm) it feels like a powerband on a 2 stroke bike kicks in
and to prevent rear ending the person in front you have to lift off and dab the brakes

just for the record im 42 and hate tailgaters with a pashion

[gregned]

I'll take a note of the behaviour today and get back anything else to check?

There is supposed to be a re-flash to fix this from what I've read here.
Ask your stealer if he has the re-flash. If he says "huh" then ask him to go find it.

[Homer]

just for the record im 42 and hate tailgaters with a pashion

Would pay to stay in the left lane then

[shendaikary]

the only other trouble i had was with the genuine canopy tail gate not latching proply but this has been recterfied the installer didnt adjust it properly in the first place

and thanks i will ask about the re-flash

[Homer]

Have a look here if you need info viewtopic.php?f=18&t=4169&p=64004#p64004

[gregned]

ok tried it today 15 to 25 kph then 1/4 to 1/3 throttle (normal for me) all ok go half throttle and yes 2 stroke syndrome

I've got a ML, but a mate bought the MN auto, and driving it, that was the first thing I noticed, how doughy it seemed. He wasn't happy about it either. He bought a chip for his and reckons it was the best thing that he could have done. It got rid of the lag.

[lazarus]

Where did he bought chip from and how much he paid for the thing and for installation please?

[shendaikary]

went to the dealer today to enquire about the hot fix and was told that the engine performs this regulary by its self and that doing it in the shop would have alsolutly zero affect

[lazarus]

so what are you going to do now?

you must have gotten the auto update version via satellite coms ....mine changes its own oil

Change dealers mate.

a change of dealears would be the best choice if there was another in this town otherwise it is 100k up the coast
does any one know if somewere like ultra tune can do this stuff

[Homer]

Sorry mate, not so funny now

I don't think anyone else can perform Hotfixes - bit like wty I think, but don't know for sure.

For sure Ultra tune etc can do servicing and everything for you, but I would assume the updates are in house Mits fixes?

For mine I would call Motorama Hillcrest (3802 6501) for some advice on what to do....the service manager (Russell) is also state service manager I believe, so he may be able to help with supplying info to your local stealer?

Come to think of it someone told me on the weekend he is relieving at another branch for a bit - still worth making contact.

[shendaikary]

was told that later this month the dealer is expecting a state/east coast bigwig to visit
the BW is susposed to be a guru on tritons and they have "promised" to raise my conserns
so in the meantime I will keep reminding them about it

will keep posted on further developments

[sjp]

my mL does it by just pressing on the pedal in the carport ,at about 2400 rpm every time, dont have to take it for adrive
checkup on thursday

The manual mentions the motor recalibrating from time to time and the sound of the motor changes a little when it happens, but it is more for emissions / controlling the smoke and not an actual reflash of the ECU.

i have been to the dealer were they pluged it into the machine and give it the all ok

Plugging it into the computer wouldn't detect a fault as it isn't a fault as such. Reflashing the ECU changes the factory settings / values that were orignally programmed into the unit to new revised values that would change performance... or at least that's how it works on the machines I install.

[shendaikary]

Sorry mate, not so funny now

dont worry didnt take offence
i think that the dealer just wishes i would go away

[patto]

Dont go away!! keep haselling him. And if the Big wig from the east coast is named Shannon tell him Patto says hi! and ask if he likes driving around in a ML that goes into Limp mode all the time. Im sure he will appreciate it.

[gregned]

I fitted the chip it performance module on Sunday And can now say the take off lag has gone its much safer at round abouts now especially the one on Fularton road where you need lightning acceleration to get anywhere (I'm sure the Adelaide guys will appreciate this)

[lazarus]

I just wanted to give it a try so I disconnected battery on my MN GLXR and connected it again and the bloody thing is noticeably quicker from the standstill, it reduced the lag quite a bit.

Don't know why and how, it just is.
Did anyone else had a crack at it like this?

Cheers

how long did you disconnect the battery for

[Homer]

They say to disconnect the negative and pump the brakes to clear the ECU quickly (this is what the boy racers do before staging at street drags) otherwise disconnect negative terminal overnight.

That is what I was saying about the ECU 'learning' bad (or slow) habits. The disconnect is supposed to be a sort of reset. Don't know how effective it is to help it 'learn' something it didn't already have - that is remove turbo lag?
