Omega Electrical and Audio Help / Re: Hard Disk MP3 Players

« on: 02 December 2006, 15:32:25 »

good point... however the wireless FM transmitters are kak!

Because the rear window acts as the ariel in an Omega, it sounds crap as the signal has to go to the back of the car, i tryed the Gifiin iTrip, it sounded apaulling up front in the car, only got better if i chucked the ipod on the back seat, but it was still sounding crap lot of hissing.

Had a wired FM mod in my old Mondeo, that worked very well. Although the cabin was a lot noiser than the megga, so that prob masked some of the noise

Not as good as wired connection.  However, with the wireless ones, there is a huge variantion in quality...

To repeat, I like my tape adapter.  Hella cheap, and sounds just as good as CD changer on my Bose system.

I just plug my ipod into a tape adapter, works a treat.  Mine's too old to charge by usb, but firewire is 12v so I am thinking of hard wiring a firewire socket in.

I have tried an iTrip in another car and it had to be within 10cm of radio to work.  Very annoying.

Omega Electrical and Audio Help / Re: Xenon headlight problem?

Does yours display the fault 'Headlight Field/Vision' as well?? And if so,what fault did yours come up with??
Or is it that your adjusting motors have given up??

Yes.  The error codes were about the voltages at the motor.  Unclipped the plug and gave it a good clean.  Got different but similar error codes.  The expectation is that the mechanism is stuck.

Mine does the same thing.  TB read the codes twice.  Next step is to take assy out and try to free up motor.  Mine is pointed straight at the ground, so obvious even without codes.

That's pretty cool.  I just use a tape adapter.  Sound is very good, and you can set the bass/treble for the iPod, but it doesn't charge.

Carrying on with the modding theme,
I read earlier about chips etc etc.
Now coming from a GEMS ecu on a scoob, mapped on the road, to take in all the mods on the car,
If you de cat your car, cone filter rather then the airbox, 3.0 cams, 99/100 ron petrol, how does this chip work??

If the chip was made with a standard car in mind, then the parimeters for fuelling, air intake, are upgraded so it plugs onto your ecu board and off you go.........

However if you have de catted your car, 3.0 cams, and like me you have the choice of better fuel 99 tesco/100 shell, then how does this chip read the extra mods.....or doesn't it................or when people mention chip on this forum, is it a chip that can be played with on a rolling road with a mapper?

Sorry for all the questions, but if you don't ask, you'll never find out,

Kevin

Standard ECU's are pretty flexible in terms of mods, but that doesn't mean that they take full advantage.  I have only heard of 'normal' chips for the Omega, which I think require super premium.  They are 'off-the-shelf' install yourself jobbies.  I have not heard of chips for cams, etc.  You may be able to find someone who will custom map your Omega ECU, but rare as hen's teeth.  Not worth it anyway, you can't get very much compared to a turbo engine.

Both the GTI and WRX need to be chipped to really be any fun, exhaust helps too.  Then they are reasonably quick, enough to walk away and leave an Omega.  That said, I know what you mean.  Neither one has much appeal to me even modified.  Certainly not in FL where there are very few roads to enjoy them on.

I would disagree with that, i have had an impreza chasing me he went half a car ahead untill about 100mph
then i pulled away but again mine is a manual.

If it was a WRX, then it wasn't chipped.  Differences are also less apparent above 50-60mph, and I would expect an Omega to hold its own over 100.  I was more talking about back roads, but a chipped WRX or GTI can hold off an Omega light-to-light.  I have had a chipped WRX, and I have driven several chipped GTI 2.0T's and 1.8T's.  Without chips, they aren't fast at all.  The suspension on the 1.8T is useless, even modified.  The 2.0T is a much better car.  On the other hand the 1.8T GTI can be modified to over 400hp at the wheels with stock internals . . .

Both of those cars are for chucking around, which is far from an American driving style.  They handle well but not great for what they are meant to do.

Making manifolds will be twice as expensive, since there are 2.  I haven't seen one in person, but they don't look that bad from the pictures.  They certainly won't be good a bang-for-buck mod.  The cheapest route would be handmade headers, but pretty tight in there.

Centrifugal superchargers are by far the easiest major power boost to an NA motor, other than NO2.  Trust me, you don't want a hand-made installation of a turbo unless you have paid someone a ton of money and/or really know what you're doing.  On the other hand, you are going to need a special ECU chip for the turbo or supercharger, and/or you will need a properly set up additional fuel controller.

A centrifugal supercharger set for 5-7psi, an additional fuel controller setup, some handmade intake plumbing, lots of octane additive, and the philosophy that it is a learning experience (in other words some very expensive stuff will expire with a loud bang!) and you could have a fun project.

I have to agree.
Though the Omega ain't very slow, all things considered.
I must confess I've spent weeks in not months looking for a Turbo for the 3.0l, and Can't find one.  

Though mine has the spare wheel, and boot lining removed, Alloy wing added to the boot
If anyone finds a Turbo mod for the 3.0l I'd be VERY intereasted.
I'm going for handling mods, unless a Turbo, or supercharger mod comes along.

I did have a "brainwave", could one convert a Turbo charger to mechniclly run from the alternator or another ancillary unit?

Cheers.

Matt

Yeah, it's called a supercharger!    Seriously, that's all a centrifugal supercharger is, a turbocharger cold side geared to a belt pulley.  People have messed around with electrical superchargers, as in run form an electric motor instead of a belt.  Don't think they got anywhere interesting.

There's always NO2 . . . .

Allow me to add up to your turbo reliability valid comment a few things for general education. A turbocharger is only prone to failure at high altitudes where the impeller speed exceeds its limitations due to low air density, it is prone to damage when the air filter is not filtering well, and finally if you don't let it cool down after a  long drive, carbon formation can damage the bearings. So if you prevent these things from happening there is no reason why the turbocharger should not outlast the car itself.

Most turbocharger control systems can handle high altitudes.  I have never seen one go due to ingestesting anything on the cold side other than it's own retaining nut.  More of an issue probably with construction equipment.  Baking the oil can damage the bearings with high mileage, not a problem with water cooled turbos until well over 200K and then only if no after-run pump.  Unless you have a ball-bearing turbo, what will kill it quickly is thrashing it when cold.  Otherwise, only high EGT's are deadly, but that is a tuning issue.

One mans meat, another mans Poison.

Cannot help but totally disagree as to which  is the better FAST road car for everyday use.

As Laidback said, the Omega is superb at what it was designed for a lazy, comfortable mile muncher. Fast A to B car on normal roads, NO give me the Saab anyday.

It depends on the driver, what type of car you are comfortable hustling, cornering style, whether you know the roads well, and how much you really push cars.  For instance AWD is rarely the 'fastest' in a pure sense, but it is usually very forgiving and can allow a medium talent driver to do a good turn of speed on unfamiliar roads.  

The Omega can really hustle on the twisties if you give the suspension enough time to take a set and you are smooth.  Me, I'm not comfortable pushing cars that are not a little forgiving on open roads.  You never know what you might come across in the middle of the turn.  Even then I don't push them to where I'm in trouble if I come across a bicyclist or something.  It's just not worth the risk.
