Re: 1G DSMLink log/tune ... need some advice
It looks like you have it about perfectly on the edge for that boost level. Maybe try pulling out 1 degree from 5000-6000, to see if the knock goes down at all. Around that area is usually where you will be most prone to knock. I usually shoot for low to mid 11 A/Fs on pump gas with DSMs. But some cars need high 10s/low 11s to handle much boost without knocking. You could go for more boost on pump, if you pull the timing back a bunch of degrees and maybe richen the A/F up a tad bit. Be ready for your EGTs to go up a little though, the less timing you run the higher the EGTs. EGTs don't mean you are lean or that you are going to blow up. Is your base timing synced up perfectly with the DSMLink? And does it creep much on the timinglight when you have it locked at 5 degrees and then start slowly reving the car up the RPMs a bit?
