Having had my maps reset and throttle pots balanced to great effect by Austech, the problem with jerky travel/throttle has come back.

Question is, how easy is it to reset the maps and balanc ethe pots? How can I get the software to do this?

Not that I can help you on this one but I'm sure someone will be along to help out soon.
Question I have is how long ago did you have it set up?
Mine is going in Friday next week for this very works.

Castles.
Three things: -
Exhaust heat shield refixing
Oil pressure switch replacing (oil leak)
Engine full check and set up
Will yours still be there?

Just had mine done, can't remember how much but it was very little (Offord).

I would however like the software so I could do it myself.

Can someone explain to me how these get reset? Cheers.

What I mean is, once you've had them fixed how does that work become undone?

Why though? I've had mine reset before and a week later they needed doing again. I have had the throttle pots replaced too.

This is a common problem for a lot of people, I'm just curious as to how it happens. Is it wires corroding? Or vibrations knocking things out of position?

Dealer told me it was vibrations that messed them up.
A slight tap of the finger on the top of a pot and the setting had changed. Delicate things!!

Sounds like someone could come up for a mod. Something that will nullify the offending vibrations.

Don't use easimap, as the map isn't actually in the right place. Easimap can't see the correct adaptives on the cerb.

You need the dealer diagnostic software. This allows you first to balance the pots between left and right bank and then clear the adaptive values.

Adaptives are predictive map values to allow for the fact that all information the car sends you is old hat at the time you recieve it.

You can use the ECU to decide whether you got it right but not if you'll get it right. Adaptives are the result of this argument and therefore form a better guess for next time.

P.S. I bet there will be someone who can do this for you at your local meet.

How would the normal man in the street get his hands on the dealer diagnostic software?

Someone called me the Cerbera Womble the other day, don't know what they meant but perhaps I need to change my ID?

The throttle pots used on the Cerbs are cheap cr4p, I believe Joospeed has access to better ones, but they tend to die or more likely become 'noisy', hence the mapping is trying to hunt for a correct setting, ergo rough running. They can be set with the aid of the software but you will also need a flow meter (a Weber part from Demon Tweeks) to ensure you balance up the banks correctly. If you are unsure, don't do it, talk to the specialists. If you want to ask about any of this best email me off-line
