What did you do in the garage yesterday?

[Mr Haribo]

That's interesting on the spring I've often thought about that, shorten it or add more washers and if so how much ?

Peter, that looks fantastic. Lovin those wheels now they are in silver.

Nice , you even fitted stickers .
Are they 17 "?

17 inch all-round and proper stickers from eBay!

Cheers Ian, I'm really pleased with the result.

Probably getting rid of mine , costing me 500 quid a year ti have it on the road and never use it .

Bloke, we all know you probably have that in loose change, or stuffed down back of sofa. What will you do with the cash if you sell it, count it? Put it away, take it out and count it again?

He has twin small children......that's enough to send it down the plughole.....

Following fitting a Impreza rack my steering is now a bit lighter than I'd like so I thought I'd have a go at increasing the castor angle. Its now got a 14mm of spacers in front and 4mm behind. If I've worked it out right it should be around 6degs now. The self centering is much improved but its still too light. Next up is tweaking the pressure relief spring in the pump.

Nice

Am I missing something here,
I'm sure I have something like one 7 mm spacer in front of ball joint and not much space for anything else.
Do you have widened top wihsbones or have reduced ball joint size.

Yeah its a cut and shut job. It ended up a bit wider that I was planning thanks to my hack saw and enthusiastic angle grinder skills.

[SILICONEKID 345HP 12.03]

Is it possible to lower the steering assistance?

Good idea that is

I took a look at my own and based on the ball joint size I'd worked it out

Interesting that you've added castor, hmm so your bringing more of the rear edge of the tyre into play and pushing the centre line further forward of the axis line. Interestinnnng.

I did notice as standard they are not far of vertical already so very little room to play reducing castor, on first viewing now I've looked it does appear that more Castor rather than less is possibly the way to go.

Been suspecting a slight loss of power for a while now but convinced myself it was me getting used to the performance. Just to make sure, I checked all the leads and plugs with my spark tester and no problems.
So left it at that.....

But, after holding off the very first AC Cobra after the Ripon car show 2 weeks ago, I thought I'd have another look. So plugged in my Launch x431 and managed to get some results in the OBD2 program (MBE fitted but I don't have the software).

3 fault codes:

1. PO560 - system voltage
2. PO273 - cylinder 5 injector circuit low
3. PO200 - injector circuit/open

So cleared them then ran the engine for 10 mins to get it up to temp. Then did another check in fault codes and pending fault codes:

1. PO273 - cylinder 5 injector circuit low - permanent
2. PO283 - cylinder 8 injector circuit high - pending

So, all 8 injectors will have to come out. Can't decide whether to refit them after a clean at Injectortune or get a secondhand set of Vectra ones - GM 90501588 - and have them refurbished instead.

Have you checked the plugs on the injectors? Could it be as simple as loose leads? Apologies if you have already mentioned this.

I was hoping that was all it was but unfortunately connectors are good. Power supply checked and earths and all good.

[carsy]

Iain, i`m not sure the Vectra injectors will flow enough for your high hp motor.

Also are you running fully sequential. Just wondering how the ecu can pin point individual cylinders.

[Sardonicus]

See if you can move the fault codes by moving the suspect inj's around on the fuel rail all this OBD stuff is all very good but its how you interpret the info and thats hardly infallible BMW are no exception to this rule Carsy is right regrading the Vectra/1588 inj's too, low voltage maybe a previous low battery condition, the inj fault codes maybe spurious hence whey I mentioned swapping/moving inj's, recent fault codes 1st then start from scratch after moving inj's

Up to what Bhp are Vectra injectors good?

[carsy]

QBee said:

Depends what pressure they are running at. When Jools mapped my 4.3 with the standard 2.5 bar regulator he said there wasnt much left and that was 265bhp.

I ran them on my 300bhp 5 litre with a 3.5 bar regulator and they were fine.

[QBee]

And what bhp are you running Iain? And is it the 3.5 bar regulator Eann normally uses?

Yes Simon, I will be moving them around just to make sure but these are the original Lucas injectors with 54,000 on them now. Yeah, I know about spurious codes ( ) so did do the clear, retest several times during the day.
There is a definite partial miss which I originally thought was HT related but all readings on the spark tester - peak, min/max etc are all good and very similar.
When Dom mapped the car he said the injectors were holding back the power. On his rolling road, 355 at the wheels. He said that was the absolute limit for the Lucas injectors and why the power drops off as it does. I chose not to go further as the drivetrain would need beefing up.
The flow rate for the Vectra ones is just slightly higher from what I can find out and the spray pattern on a more modern pintle type is better than the disc type. Being a cheapskate, was hoping for a simple swap.
