cobb ap knock retard ?
ok noob here......I just got a cobb ap and fired up stage 2. Well I went into live logging and went into "knock retard" and I'm getting a reading up to 2.4 at low rpms, but I did a few WOT and got one reading up to 1.8 and seeing a few pulls over 1.1......how bad is this and what can I do to fix issue? What else should I be looking for in my cobb ap live data logging?

no wb or atr, I need to get that stuff soon. I thought I could run stage 2 with no big issues. Dang, well what can I do to make knock go away? I got 50/50 mix of 100 octane and 91 and that didn't seem to help much. I guess I'll go back to stage 1

Well if you don't know what your AFRs are I would check Fuel pump relay. Might be going bad. Could be to lean, bad gas, timing all kind of stuff. But I would change your fuel pump relay with headlight think it is and re-log. Find thread on here or look in your manual and see what one is the FP relay.
Also what year?

Sorry...
Formula is
Knock Retard (CA) / .35 = knock count
examples:
.35 = 1 knock count
1.05 = 3 knock count
2.46 = 7 knock count
12.66 = 36 knock count (I sure hope you don't see this one lol)

But if its at same rpm area and starts to knock .35 or whatever there is a problem in that area with timing or whatever. Lets say everytime you do a pull in 3rd or 4th and at 4500rpm you start seeing knock everytime there is a problem. Now if you do 3-4 pulls and 1 pull out of them there is knock at that rpm area your fine.
