Any advice?

Give Thorney a call -I believe he knows what to do - also Mark on this forum knows I think?

I don't know btw

Nick, I had the same issue on mine. It's a well known CSL thing on the dyno.

However, no-one would tell me how to get round it so I don't know either!!

PS Was it Andy's car?

you need to find a synchronised dyno (front and rear).....your car doesn't rev after 6 because the 4 wheels just don't turn at the same speed and the computer system of the car just prevent revving....i know one of these dyno in..............................france

Yes, thats the one - we had a dyno day on Sunday which was a roaring success, 29 on the rollers and loads more just turning up for the day.
So we need to do another one sometime soon and I want to be prepared. There was a 7series with the same problem as well.

Not always - there is a little CSL trick.. couple of twists of the key and a prod or two on the asc button.. trouble is I have forgotten the sequence!

Hi Nick

Try john Thorney motorsport for a rolling road would be my advice

Not all rolling roads know how to do the M power cars.
