SD questions really quick With my setup I have a SD tune (i did not do the tune). I am showing a code P0102 for the MAF not getting voltage (no **** its removed). I assume that this is no big deal? I understand that the maf is not needed nor is it there. My question is, is this somethign that is turned off with the tune, or is this just something I deal with.
Also right now I am retarding (false knock I assume) as I hit 3000 RPM's. Cannot shake it. 20* of timing and my A/F is at 12.5. through the whole run. I see no knock or retard during the dyno or hard runs, just every so often I get the codes of P0332 (2 low freq knock) just from regular driving, yet when I look at my dyno it looks like an EKG onc ei hit 3000 RPM's it goes nuts. Any ideas? Anything physical or is it jut the tune? I am running a MP112 blower at 9-11 lbs of boost. The block is a fresh rebuild by a quality guy, everything else is stock. Stock heads, Z06 cam, manifolds, cats you get the idea

The MAF code will always be there. You just disable the MIL from coming on with the code. The fail actually has to be there via either failing the MAF in the Diagnostics or removing it to force SD calculations full time.
