I didn't dig through every little thing in your log but the basics look fine, MAF, O2 sensor stuff, the MAP sensor, etc.

Is it okay to drive it home with the knock? Got a two hour ride home that I can baby.

It's not knocking in the latest log, it's just doing REALLY strange stuff with the ignition timing which is making it all herky-jerky.

Look where I hold it at 4-5k rpm. It happened consistently off and on.

yep its knocking see log zoomed in here, iam dropped a bit as well its pulling over 2 degrees arround 4500 rpm

then it looks like maybe some failsafe or something in tune cuts in and drops ignition timing lots

is traction control switched off ??

Yeah a bit of knock there, but it doesn't explain the bizarre spikes of negative ignition timing. I think the knock is a separate issue (still a problem, but I'd fix the other issue first)

yep something going on might be some form of safety cutout in tune based on knock or boost ect or possibly traction stability , hes going to need to talk to the tuner i think

Tuner sent me 4 revisions before we fixed it. When he lets me know what it was I will update. Thanks!!

It was an intermittent wheel speed sensor issue. Causing a fail safe and cutting power. Removed that restriction and we were good to go.

oldgunfan · 03-14-2016, 06:32 PM

Well I have been playing with my MAF scale I think i'm close but around 2500 to 4000 it's going from rich to lean. I'm thinking I need to play with my load limits. I'm using Wayno's load limits. Any ideas?? my pull http://www.datazap.me/u/oldgunfan/ge...ata=1-3-4-9-14
