Omega General Help / Re: turboing your v6

« on: 24 July 2010, 15:43:49 »

If this is on the Omega would a supercharger not be easier, there is space to squeeze one in - I wouldn't fancy the chances of getting a turbo in against the chassis.

Came to a similar concusion personally, then thought fitting a lower geared dif would be easier cheeper and easier to insure.

Has this helped a lot?  Always thought circa 50 mph in first put a dampner on the 0 to 60 times  Did think about nitrous a while ago, its there when you need/want it but doesn't cost anything if you don't.

Mine just cost me about £300 inc new water pump. Current Vauxhall dealer mechanic did it in my driveway about 15 miles from you. PM me if you want details.

He's charging you too much 

Or your too cheap Pete

Omega General Help / Re: camshaft sensor

« on: 22 July 2010, 21:57:42 »

Camshaft is usually (not always) a hall effect device, three wires as you say, power (usuall 5V), ground and then the output, which as you say is a square wave as seen on the scope.  What scope are you using out of interest?

Just re read your post and if your engine is a x20xev it could be using an ac excited sensor that is pretty unique to that model (thank god).  Try using another channel and connecting to another wire, you should end up with two sinusoidal waveforms slightly out of phase.

Hope that helps

Omega General Help / Re: MV6 Seats

As far as I know MV6 leather rear seats are not heated, all the seats should fit OK but you will lose the electric memory etc etc.  I have the same idea and also have a full MV6 black leather interior (which will be for sale) but can't bring myself to lose the electrics - have decided to fit facelift elite leather (mines a mini facelift) as a compromise.

I have a full MV6 leather interior that will be for sale soon, decided against it as I really like the full electric luxury and don't want to lose it

Omega General Help / Facelift seats in a mini facelift

« on: 12 July 2010, 23:00:17 »

OK I want to fit facelift elite seats to my mini facelift elite, have read that they are not plug and play.  The main problem being the heaters, if they work at all anyway.  Does anyone have a wiring diagram to confirm this?  Any help appreciated.

Omega General Help / Re: code 19 incorrect rpm signal

« on: 14 July 2010, 00:15:58 »

OK so what code would be produced if the phonic wheel that the crank sensor is looking at had a damaged tooth???

Please don't say my advice is wrong.

The fault code is saying incorrect rpm, this could be produced for many reasons if you think about it a little.

Sorry not so good on these forums should be quoting dbug here.

Probably a 31, possibly a 19, dependant when the breakage occured, as the engine wouldn't start even with a good crank sensor.  However suspect that to be a very very obscure fault - normally a 19 refers to failed crank sensor (wiring usually fails not actual sensor) which is a common fault on Omegas due to the close proximity of the sensor wiring to the exhaust.  Rerouting helps it last longer!!

If the phonic wheel that the crank sensor is looking at had a damaged tooth, clearing a 19 code and waiting would not help.  As the engine would not then start, the only code showing would be 31(Engine RPM signal (crankshaft sensor) - No signal)  - normal for an engine not running.  Still think your advice unhelpful - sorry my opinion.

19 fault code is saying  "Incorrect RPM signal (crankshaft sensor)"

Interesting opinion, to be fair I suppose it depends on the intelligence programmed into the engine ECU.  A Renault fitted with an incorrect flywheel (two missing teeth) after a rebuild was happy to idle at 1600 rpm for example.

Anyway enough thread crashing for one evening I think

I'd be guessing a normal CS output would be square wave ish with an elongated space at TDC going off the cutouts on the wheel. So wheel damage would give more long space pulses maybe.
But wouldn't you then get a similar signal with a wire on the sensor intermittently shorting out?

Nearly, you would think it would be square because the teeth are, however the teeth actually produce triangular peaks if that makes sense, correct on the missing tooth producing a gap.  If people are interested I could post an example, if I can remember my password for images  :-/

Due to it being a proximity sensor not a digital on/off?

Yep pretty much - most crank sensor are inductive, generating there own voltage.

I agree Entwood, without the right equipment its the only sensible option and very good advice.

However I don't think resetting the code and checking it reappears is bad advice either.

Enough said I think

I reckon so too Daz, got the head gaskets and manifolds done and all running lovely,  bodykit and LPG swap over still to do - will drop by soon
