high knock readings
 

driving along the motorway yesterday & after planting my foot to overtake I noticed a 75 reading on my Apexi Power FC.

I've not seen a figure that hight before & the CEL didn't come on which I have seen before it was mapped properly.

Its going to the garage next week, but I'm a bit worried. I did hear a rattle from the exhaust on overrun, so I'm thinking it might be that being picked up?

TIA

Ello matey, what fuel were you using at the time? I have seen those type of readings when I used the Apexi & only used to do it sometimes when I had a lead foot in 5 gear (if I added some millers to the tank it wouldn't happen).

Sainsbo's super unleaded @ 1.3 bar - I'll knock the boost back a bit & see what happens
