Knock and Link
This is a double post with m.net. Maninlt because the Fm Link seems more popular there as opposed to the eManage here.
Either way - if someone can help it would be really appreciated.
I installed the Link and LC-1 loaded the appropiate turbo defaults and set off to tune. I did some runs and logged them into DLL and found that I was getting what appreared to be Knock at the higher revs.
Basically I had zero knock > 5222rpm, then
small knock readings (upto 13) > 6696rpm, then
increasing to a max of 65 at redline 7200 rpm
There are no obvious spikes - just a steady rise.
My knoch threshold is set at the recommended 35
I noticed that the car was not pulling any ign and could not work out why.
As I understand it the threshold near doubles as it approaches redline as you expect greater engine noise. - as long as I am not getting any spikes or going over the threshold (70 at readline) then i'm in the clear for Knock.
I still have some testing to do to establish the engine noise baseline - but is the above correct in concept?
