Hello,im new to this forum and was wondering if anyone can help me? ive noticed my knock readings are quite a bit higher than normal.Could the weather have any effect on the readings(very cold -2 at present)on the power fc as im running with the stock base map at the moment.My mods are downpipe,midpipe,cat back,fmic,ind kit, 1-1fp reg and ebs4 boost controller set at 14psi.Also does anyone know what sort of power at the flywheel i should have.Thanks in advance Roy(uk).

what's your peak knock number (WOT at partial throttle)? What about your avg knock number while driving? Has it gone up lately or just since the weather got cold as crap there? Bad tank of gas?

A little more info would help.

Yes! You could be in the danger zone under boost! Temperature correction factors could be way off for -2C. If you want to see if this is the case, up the PIMS for fuel for rpm ranges where you think the knock is high. Go up to 5% increase (change 100 to 105) and drive gently. Be careful. This is prime engine popping ground if you have no idea what your AFR is at.
