Wierd Log

[I_eat_DSM's]

I'm sorry if this issue has already been worked on but I'm new to the whole logging thing, and I tried to search but I couldn't quite find what I'm loking for.

I have been logging my near stock (intake, exhaust, no fuel mods etc) 14b car, and I have encountered an extremely weird timing issue. When I am WOT, I read no counts of knock, but my maf pegs very ealry at 1603.9 and as soon as it does that my timing dips way down, (1-5*) and then very slowly rises to about 10* throughout the rest of the wot pull. I am not really sure where to start, so any help is appreciated. I have the cas pretty advanced because I cannot get the car to knock, and yes I am sure my knock sensor is grounded correctly. I also get PLENTY of timing advance while cruising, I just have very very WEIRD timing advance during WOT.

Do another log with Timing, Rpm, TPS, Rpm, and knock. Start around 2500 rpms and don't let off until near redline. Where exactly is your base timing? Are you sure you're advancing the timing with the cas? Is you maf sensor hacked? How much boost are you running?

 

[I_eat_DSM's]

I am running about 16 psi, and yeah I'm sure that I am adding and not taking away timing with the CAS, however I'm not rully sure where the timing is at since my crank pulley doesn't have timing markings. My mas is not hacked, and I will post another log tonight and tomorrow I will try to check out my base timing some more. (if i had to hazard a guess I would put my base timing around 10-11*)

-Update: Car is in the F'ing shop because I busted something so I guess it might be a while before I can post a new log...
