Had the Scoob out last night for the first time in nearly 3 weeks

Warmed her up properly as I always do and later when accelerating, the check engine light flashed. I stopped and pulled into a car park and checked my apexi hand commander and I saw a knock reading of 81

Do I have cause to be worried?

 

anyone?

I know its a noob question but am still learning

 

I wouldnt be worried if it was just a one off after being stood for 3 weeks and the drop in temp over the last couple of weeks. If you start seeing knock more and more often oreverytime you have WOT then you can start worrying or contact your mapper.

Thanks for putting my mind at rest Mike

will keep an eye on it

 

If you hit the rev limiter, that could have caused the high reading.

 

I still get phantom knock readings when on cuise, as high as 60 sometimes.

On boost at 1.45bar I get 12-15 normally so I dont think its much to worry about.

On yours at 80, could it be something other than the engine making the noise being picked up by the PFC?.

deffinately didnt hit the limiter mate


S'pose it could be something else, hopefully it was something else LOL
will have to keep an eye on things and if it happens again then investigate

Cheers for all your advice

 

if the car has been stood for a few weeks then the fuel will have degraded n octane rating, this could also be cause for the high reading.
