Alfa 156 TS Veloce X Reg
------------------------

Anything mechanical to do with cars scare the living daylights out of me and today i've decided i need to get to know my car better . .

So im thinking that to resolve the sluggish'ness when in FIRST gear I am going to reset the ECU.

I've found the instructions on here but I need to disconnect the battery first.

It seems to have 3 leads going into it - 2 into the black box which opens up and the other to the left of the battery.

Do they all need disconnecting ?

Anything i should be aware of when disconnecting these leads ?

Yeah im dumb but id rather do things the right way than bugger the motor up !

Thanks for your help.

Disconnect the NEGATIVE EARTH cable first which should be the one nearest the front of the car with a - sign near battery post. Think it's only one cable. (Hope that doesn't come across as patronising!)

That way if you accidently touch the body work with the spanner you won't do any damage to you, the spanner, the car, the battery or the car electrics. You shouldn't need to disconnect both. I think its a 10mm nut.

Yes, just loosen the nut, you don't need to take it right off the bolt, and lift the connector. If it sticks, suggest you open the clamp apart gently with the end of a flat screwdriver between the end with the bolt.

Clean the battery post and give it a thin coating of vaseline if you have any (and not being gay you probably don't! ) It stops the battery posts getting damp and giving you starting problems. When you put it all back don't over tighten the nut and bolt, but make sure it is secure. A loose terminal will also cause starting problems.

PS Welcome to the forum ... you will be expected to post pictures of your car very soon ....

Well the ECU has been reset and after taking it for a spin (or rather 'A Good Thrashing') i can confirm that it is running very smoothly indeed.

Not sure if its a result of the ECU reset or whether the oil and filter change on Tuesday helped !

Had it up to 105mph on the M25 towards heathrow then decided to slow down before the unmarked copper saw me on the side of the road..

Coming back I slowed right down after seeing a nasty smash between a Van and a Lorry which resulted in the Van driver's head being bandaged over his eyes too. Not good but a reminder that speed can be dangerous.

Im assuming theres a post containing the forum users cars ? Am off to find it and post some piccies.

Cheers

Over and out.
