I have read in a few places that a ping reading under 60 is safe.

Is this for basic ping or advance ping or both ???



My basic and advanced read totally different.



Just installed the PFC 3 days ago , but these are the readings I have so far



At idle ---

Basic moves around between 1 and 20

Advanced moves between 0 and 1



During normal driving (no boost , rpm under 4k) ---

Basic will go up to 150

Advanced will only go up to 14





Is this normal ???

Which one needs to be below 60 ???

(I hope not both)

 

your car needs to be tuned bad.......stay off boost!!!!!



umm you want under 35 normally after tuning......

 

ok , but i am below 35 on the Advanced section

and way above 35 on the Basic section

What is the difference between the Basic and Advanced ???

(the datalogit peeps have not given me access to their forums yet)

the way i read it on datalogit forums. its an average. both should be low!



i have a commander also so use what that says...

 

150 is really bad!! what mods you do to your car besides the pfc?

 

K&N , straight through exhaust , wp and alt pulley ,



A/F = 12 at idle , 14 at vacuum , 11 at boost



i will be tuning this weekend and mapping to see which squares are getting the high knock , i was only looking at the max hold before

 

sounds like you have too much too little fuel and too much timing in some places.....also make sure you don't have a boost leak that will cause high knock #'s
