Made some runs with autotap lastnight. Just wondering what you guys think my tune looks like. Outside temp was 48 degrees. I see on instance of KR with like 7.7 deg of knock on the first run. What the hell is that all about? Did not do it any other time that high. Just so you know this is a nelson tune, other mods are in the sig. Oh also their are a total of 3 runs in excel format. Thanks guys!

 

Looks like you need more timing. Going from 10-12 degrees to 15-17 degrees will give you a big gain.

I see some knock though, not sure if it's false. I'd get it widebanded to make sure your Air/Fuel is safe before adding timing.

 

TTT

 

Exactly what I noticed too. More timing Your fueling should get a little bit richer when you add timing too, so you should be good with fuel. Try adding 2 degrees to HOT table. ...no knock? add 2 more
Like Black Blown said, four more degrees in timing will make a Huge difference with your boosted application.

What was ambient temp outside on the runs? just curious

 

11-12 degrees at wot

comparing it to some radix logs I looked at
something dont look right
but what do I know i dont have one

hit up blownchevy flyer or one of these radix/FI guys
Im sure they will help

I would definitely take it to a reputable dyno where theyll take
the time to get it right

hate to see something bad happen that a couple of keystrokes
could have prevented

then again it may be safe
chance I wouldnt take though

 

About 48 degrees

 

I can't look at the logs ... but going from what others have said, you have a LOT more timing to add. You should be able to get close to 20 degrees of timing.

I have the 6.0 heads on mine (lower compression) and run somewhere around 29* at WOT and don't get any knock.

 

The files are zipped. Once unzipped you can view them with excel.

29* is crazy timming that is on what pulley/psi? Sounds like nelson need to "tweak" my tune a little.
