Does The VX-Commodore Have a " Self-Learning " Computer.??

[Lethal_1]

Hi there ...

Recently ... I just had my VX serviced ... 130,000K actually ... It also got Engine Mounts replaced too.!!

Anyway ... When my Mechanic replaced the Engine Mounts ... He had to " Dis-Connect " the Battery.!!
I was told that my VX has a partial " Learning Computer " ... In this case, the " Throttle " is part of this learning.!!
Because he disconnected the battery for 4 hours ... I have now lost my learning computer settings, & now the car " Feels " gutless now.??

Of course it's not ... It just feels like it ... But I can " Definately " FEEL the difference.!! - It's definately not the same as B4, before he replaced the engine mounts.??

* How do I get this power back " Faster " ... Without having to make it learn all over again.?? - It's done 2000K since the service.!! - Only ever used Premium-ULP.!! - Any Idea's.??

firstly i am suprised ur running premium ULP. How much u paying per L, close to 2 bucks?

Secondly i think the learning computer has to do with the throttle/ gear box. The faster u drive the faster it will try to change plus holds lower gears for longer to allow more power but at a cost of economy. I am guessing to get better performance in the first 10 mins of driving drive harder so it programs ur driving habits and setups the car for ur driving style.

other then that i got no idea.

By the year 2029 all early model commodores will become self aware, and the panic to shut them down, they will launch a massive counterstrike!

Seriously, check that all the little hoses under the throttle are plugged in. The link between moving an engine and unplugging the battery is not what you are suggesting here. I would say something else has been bumped or dislodged.

Also can you measure the performance by driving it and watching the speedo? does it do a reasonable time, close to what the normal time from zero to 100 is? Because if this is true maybe it is just that the engine does not vibrate and gives the illusion of being sluggish, when it is just going about its business alot more smoothly and quietly perhaps?

Also running premium ( according to the ads ) is cleaner air for us to breath less sulpher.

2000km after the service it should be back the way it was...

Normally within a days driving my car used to feel more aggresive than just after a reset.

I think feg might me on the ball about less engine vibration... same as when people remove their resonator and then say the car is faster... Not really... just more noise to it SOUNDS faster..

Good luck

Thanks " Hot-Rod & Feg " ...

Yeah, I know ... And I am normal, the prices @ the moment R FrEaKiNg me out too.! - ( I'm paying around the $1.45 P/L ) (QLD)
But I do agree that replacing the Engine Mounts, He (or his apprentice) may have bumped something else on the way.??

Just a quick background ; (It's an Auto, has SS-Cold-Air-Induction, 2.5" Extractors all the way thru, K&N Filter, ECU-Upgrade & the 'Power' button is always on 'Power')
* I used 2 B able 2 floor it, & have the power straight up.! - NOW, it's smooth etc, but has surges @ 5000-5500rpm ... Gradually it's surging in other rev ranges too ...

Anyway ... I've been flooring it all the time ... Just to speed up the " Learning Computer " ... So how long does it take to " CatchUp ".?? - Please don't tell me it's gonna B 10,000K's.??

And " Feg " ... Thank Goodness For That.!!!! - ( They'll all be " Self Aware " by 2029 ) - Cheer's.!!
Looks like I will have to check everything myself like U have mentioned.?? - Coz I have never had to B4.!!
I'll have to pull over on the side of the Freeway, & get my Girlfriend to time my 0 - 100klms times, & post here later.!!
I have noticed since the Engine Mounts being replaced, it has been running alot smoother, so I guess it " Feels " sluggish, but it's not.!!
I'm running SHELL V-Power @ the moment (with the 4c p/l discount, yeah I know, it's a Con), and I thought running Premium, I'd get better performance.??

Cheer's " Jesterarts " ...
Maybe it is just the vibration, or lack of now, that makes it " Feel " like it's sluggish.??
I'll give it another 1,000K's & bail my Mechanic up for the Surges I get here-and-there.?? - Thanks Guys.!!

I only ever seem to get 60 - 65 litres in mine, I could go further but don't like going to empty.

If you are going to spend the extra on premium try bp ultimate. A lot of people here recommend it, including me.

The main thing you are trying to do with premium is to try to stop the engine knock. this is mainly in forced induction engines. when the engine sensors detect knock the computer winds back the timing and will in effect slow up your engine. not sure the higher octane which is needed to help against this is useful in a NA engine. As stated earlier there are other advantages though less sulphur and pollutants apparently.... Although not sure it can help against all the diesels out there!

I think I've read that if you dislodge a vacuum hose of the bottom of the throttle body you can get odd issues like you are experiencing.

i pay about 100-110 every fill up today was 107 just use 98 youll get there in no time! if i pay less than $95 i consider it amazingly cheap! i havnt been driving long but my first car used to get $65 for 65L and it used to get alot further 650k-700k compared to 480 today from 64L
