kr at wot.need tuning input
kr at wot.need tuning input my car pings at wot. my timing after its warmed up is -24 at wot and my lt are -1.57 at wide open on my perdator... i pulled
2% off the timing but still pings. it also pings at cruz sometimes. i do have the pred tune in there and it has made the car quicker but was hoping on some input here to see where i could fix this..
pe, inj slope ,pull more timing ect. thanks

What mV's are the NBO2s reading (B1S1/B2S1)? What mods do you have done? Did you search in here for "Predator"? There's been several threads recently that address what you should do for fueling. If your fueling is close, then I'd start pulling timing.

Messing with the injector tables is often a sign of sloppy tuning. 
I would also venture to guess that you are running lean. If you have your PE table set to your desired AFR and you are at 24* WOT, it's gotta be lean. At that point, you need to start looking at your higher RPM MAP areas on your VE table. Also, if it's pinging under normal load, at what RPM and MAP? If it's at lower RPM's, you might be getting TPS knock, which is basically not real knock. If it's somewhere in you regular powerband, I'd say you need to totally redo your VE table.

Alot of times they will start to ping down low and pull a few degrees and then start adding it back in. Its this lower part of the table that if you take just a couple degrees out, and keep it from pulling any to begin with, you can usually keep more timing in up top.
the ping at cruz is rare but kr is noticed.ive seen it on monitoring pids while driving.like i said its rare and comes in at lower speeds when the conver locks up and luggin it...im not really concerned about that but the wot ping is always there.

24 degree's is about right for a 2001 stock motor setup. Sounds like the WOT is too lean.Richen it up through PE and see if the KR goes away.
About 90% of the Predator tunes we see are way too lean at WOT which can be fixed in the PE.

im gonna get out and monitor again prolly tommorow. i live in the north east and its nasty up here with ice and snow. havent ben able to go much anywhere in that car if yah know what i meen!!
