S1's are great!!!

Bold sacastic statement RUN FOR COVER

S1's are great!!!

*cough* road tax *cough*

S1's are great!!!

when did you pass mine at the SIDC day?

Saying you did whilst I was in the pits following some crank, conrod and big-end bearing collapse does not count

[meatball]

Yours has been working this year???????......sorry I retract the above statement! hehehe

[s29ttc]

Mines is all good juts some teething problems. S1 is the real drivers car, S2 just too tame for me

*Ducks for cover *

[Baggy]

He speaks the truth (on this occasion and this occasion only)

I'd take offence.....if it'd been working long enough for you to actually drive it!

We will see on track Mr Meatball Just try keep up

Right I do know I am talking pish but it was worth a laugh

Joking apart it actually hasnt been off the road apart from a couple of days at Ali's, works fine just twice it hasn't started and needed bump started.

[meatball]

I never try to keep up with S1's......I just try to avoid the bits falling off them!
Righto.....enough of me talking p15h......hope thats all your niggles sorted!

[s29ttc]

Ano you moan about all my posts and keep me off my work shhhhhhht!

Thanks mate hopefully that will do the trick tonight soon see

The door thing is a red herring on the S1 . . .

??? Doesnt need to be open or doesnt work with the door open

The door open thing has no relevance to resetting the ECU's learned IACV setting.

You say it needs bump starting to start it, and yet it cranks over healthily.

What year is your car? I'm assuming it's an S1 based on the S1 vs S2 banter. BTW, if you want help on technical please post what car you own (we cannot remember every car everyone owns) and please keep the banter to a minimum, otherwise people who actually know anything about the cars will stop reading ...

Early S1s have a problem where the voltage drop on the +12 wire is so high whilst cranking that the ECU drops out and so won't run the igniton/fuelling. Later S1s have additional power cabling to run the ECU directly from the battery rather than via the +12 lug on the back of the starter. Earlier S1s run the ECU from the lug on the back of the starter and have a lower power starter motor; sometimes people fit the higher power starter motor from later S1s to earlier S1s and that can make this problem worse.

It will be exacerbated by running with corroded battery connections and/or corroded earth straps either/or in the services compartment or the engine bay.

If you have an early S1, you can check this to an extent when the engine is exhibiting these symptoms, get someone to crank it while you measure the voltage at the starter motor and tell us what it is. You need at least 9V IIRC to get the ECU to run properly.

Cheers,

P.S. do you mean bump (as in pushing the car and dropping the clutch) or do you men jump (as in parallel wiring the battery to that of another car with its engine running)? Jump starting in particular would make me think that you have voltage drop problems.

Robin,

Scott's car is a S1 111s with the mis-fire detector kit fitted.

He's cleaned out the IACV with no joy - might get a multimeter on it to see how health the battery is in general and whilst cranking.


Cheers
