I just got a quote on an E92 M3 and I put in all my own details.

Ardennes1944 · 26-10-2012 12:41AM

It won't insure a 40yr old version of me with much ncb on a feckin polo! Last week I was getting quotes of 1150 on a t5 so something is definitely wrong!:pac:

Just worked on my iPad no problem, must be something to do with cookies etc!

Give me a couple of days and I'll have a far better odometer picture than all this rubbish!:D

Spent a week waiting for it to turn 100k, forgot about it for a couple days, and then noticed it as I was about to pull out of the petrol station. Lucky catch!

Pfffffftttttt..... Amateurs!!! :pac::pac::pac:

Parked up in Blanch and noticed this

And dodgy petrol caused that EML to come on

I'm approaching the legendary 123456 on mine, another 70-ish miles to go.

Had I really been prepared I would have reset my trip computer 789miles before that...but no! Ah Im not that obsessed anyway:p

Isn't Portlaoise around 70 odd miles away....? :pac::pac::pac:

Can a Decat affect torque?
The car feels a bit down on torque low down

I found it to be the other way round when I decatted the blue van.... Pug has a decat and no difference low down

I would have thought that a de-cat would give it more power!?

EDIT: DGT beat me to it!

Must be something else then :-(

gollywog - with a decat you are reducing the back-pressure on the turbo so yes, a decat does affect torque low down.

So a de-cat is more for like a sporty sound?

Ya, same as!

Ardennes1944 · 26-10-2012 06:08PM

handed in my car to an auto leccy this morning at half 10 and the job was to be done today no problem. contacted him at half 3, half 5 and again there now and no answer or response? dunno what to do now! need it for work at 6:30 in morning!

On naturally aspirated cars, a decat can increase performance but in a turbo charged car, it reduces torque because the turbo needs the cat there to increase back-pressure.

Ah right, I never knew that.

EDIT: Thanks

I think it's the other way around. On turbos, with a decat the turbo will spool quicker because there's less back pressure, so the exhaust gases flow faster. On N/A cars, the engine tuning is setup for the stock assembly, including stock exhaust back pressure.

I've a feeling what's happening here might be a mix of the two. Until the turbo fully spools the car is essentially a N/A, in which case the ECU is still treating it like there's still a cat, and the back pressure it provides, probably causing a decrease in low-down torque (off boost).

On the other hand, there should be a decreased spool time and maybe some gains higher in the rev band though.

I sit corrected, not too happy about being corrected by diesel boy but shur what can ya do :P

@gollywog: once you get the car remapped it should be fine, as it'll be tuned to the exhaust setup

Grand so. I just noticed it overtaking in the higher gears, seems to pull a little less but as you said it actually seems quicker once in up in the revs

i have to say that when i droped back stock exhaust with cat it became alive again. It pulls stronger over all range of revs.
You just have to map at make it proper if you really want to see some gains and not just losses.
If i will get back in to better financial position ill drop back that exhaust with new intercooler and STI turbo and it will go to maping asap.

77777 on a 7.

challengemaster · 26-10-2012 08:31PM

I'm noticing a theme of other warning lights being on as well

Voodoomelon · 26-10-2012 08:46PM

That was over 2 years ago, ABS wheel sensor.

Pixels fixed too.

dar83 · 26-10-2012 08:47PM

Decat and quicker spool turbo = super fun happy times, along with backfire on gear change.

I've the same fecking warning lights on mine, but as you probably know yourself it could be 1 of many things....

Voodoomelon · 26-10-2012 09:13PM

Yup, pain in the ass. If ever you need diagnostics I have DIS etc.

I may have to take you up on that offer

I'd be seriously pi$$ed if that was my car. All I can say is tell him he won't see you again after his poor service. How easy was it to make a call to you to explain what was or wasn't happening.

CianRyan · 26-10-2012 11:42PM

Almera lads, my airbag light's lashing like mad, anyone know how to sort this?
I'll be NCTing it soon so I'll need to fix it sharpish.
