ECMlink knock knock

I'd say that looks good. You'll just want to go back after you do a pull or two and make sure that there are all smooth transitions on the path it takes (Track Datalog).

What do you recommend for spark plug gap on a 16g at 20-22 psi? I want to rule out everything piece by piece.

 

[snowborder714]

I run BR7ES plugs at .028" for that same boost/turbo. Or you could gap them down to .026 or so.

I'm going to try and get another knock sensor tomorrow as well. I'm going to go over all my mounts to see of any of them are loose or making noise, and try to see if anything else is making noise. Going to regap the plugs to .26

New log. Changed the table to 11.2 and still getting the knock. Ordered a new knock sensor today it will be here tomorrow.

Is the knock sensor in the correct location? Mine was up at the top of the block to close to the head at one time and thats the wrong location. I was able to get more aggresive with timing and a/f after correcting it

I think I have it in the top hole, will it really make that much of a difference? And are those holes different on 6 bolts?

 

[red1993gsallmt]

yes it makes a big differance, trust me. Up in that thread you pick up all that valve train noise like I did. Never installed a knock sensor on a 7 bolt so I dont know but check your car, I remember my car use to knock when I free reved it in neutral before I moved it

 

[onefast2gdsm]

i got a 6 bolt. ill try that. thank you!

 

[onefast2gdsm]

Replaced the knock sensor and put it in the right spot. Gonna do some logs on the way home from work. Now my clutch is slipping

Try running non-projecting insulator type spark plugs. Try some BR7ES

This helps a little too but I think it will be fixed after moving it

 

[onefast2gdsm]

Nope still gotnthe knock. Started at 5000 rpm like always, got 2.5 degrees, then 7, then 12.7 all the way to 5100 rpm

 

[red1993gsallmt]

What are you tuning with? Can you send me a log if your using v3?

 

[onefast2gdsm]

Timing was 1 tooth off at crank. Pulls hard now and no knock.

Glad ya found the problem and it wasn't too seriouse for being cam timing related, one tooth can defintely make a difference in performance and is often the last thing people check. Also being that in some cases if you don't know to set the exh. cam ahead and clamp the belt to the sprockets, then rock it back the crank will never line up right. (mine has to be done this way to get everything at true TDC acording to a dial indicator)
