Might be worth having a check over for that noise. CV joints, wheel bearing etc.
Yeah I thought it went a bit lower than 10:1, as Ian had been told that the extra ignition advance it would gain would outweigh the drop in C/R. But I dont think it worked out that way.
Hope the Omex didnt give you trouble this time (map changes for raise in C/R)

We went out and did a map for it once it was back together - didn't need to touch the advance map - had to tweak the fuel maps as it had leaned a few places out.
I still suspect i'll go across to my AEM over the winter as the definable knock control on there and return decay etc. is far superior.
I don't know if you can see the AFRs clearly enough in that vid - but as well as it having mega conservative spark it was also richer than normal as the chargecooler seems to struggle to control air temps when under those sort of track conditions.
Could feel a distinct tailing off in the powerband after a few laps as the air was getting hotter and hotter.
Treated the day as a shakedown - found a few problems but i'll get on top of them and give her another shakedown at Donington on 29th December and then hopefully have a 3 month window to sort anything else
