ECU...jimmy

[Maca]

any ideas why the ecu would keep resetting itself each time the car is restarted?

What do you mean by 'reset'? It normally has a permanent 12v feed and when you take this away it loses any stored adaptive fuelling setting and fault codes. But that isn't really obvious, so unless you're looking for it you might well not spot it. What symptoms are you getting?

Cheers,

the garage boys said a fault code on their trusty faultometer indicated that the ecu was resetting itself...no elaboration...their doesn't seem to be any odd symptoms - seems to start fine and run fine. of course if its been doing it all the time i wouldn't have way of knowing what it should be like...its lumpy below 1700 revs

no, they're not.

idles fine, and revs smoothly upwards but shunts/stutters etc in higher gears as the revs fall - makes cruising at low revs a bitch. anyway...does this have anything to do with the ecu forgeting everything its learnt each time the ignition is switched off?

I dont think you will know if the ecu is forgetting its settings without a code reader. Its code is 02.Did you have a battery change at sometime? Maybe the garage were just telling you there were no codes recorded, apart from 02. I have a code reader if you wish to borrow.

not an uncommon characteristic

[Maca]

any way to smooth it out - obviously its a different animal but other 8s i've had happily cruised at low revs - is it a cam thing or is it linked to the ecu

A visit to Mark Adams is going to be my choice...it seems the ecu mapping needs fine tuning to the engine, some are better than others

[Maca]

pete, i've got mark's number...it's already crossed my mind (a little xmas present for myself)- where abouts in the country does he have his batcave?

Uxbridge and somewhere else further south west I believe.....bit pricey tho which is why I have yet to get around to it

I rang MA a few weeks ago - I admitted I was pretty much 'window shopping' at the time - v nice fellow & had long chat. I think budget for a good few hundread pounds... but... if I'm to keep the Griff for a while longer I'll save the quids & see him. BTW Cheltenham is the other place.

I can't find the details to hand but I had an ECU issue earlier in the year and found a company derby/nottingham way called something like All Car or In Car Electronics who have reconditioned ECU's on the shelf that they hire out or sell sale or return. basically they send you a new ECU, you see if the fault clears, if not send it back and owe £40 for the privilege if it does keep it and owe £150 or so. Bloody good service, if you can't find them from my descrption phone Mike at Motorvation he has their details.
