I data logged my car today and had 1 count of knock on the first log, and a concerning amount of knock on the second log. Any idea what this could be? Any help is greatly appreciated.

 

A case of beer for anyone that can help

 

For EUR 98 my AFR tuned from 12 at spool to 11.4 at redline.

 

I'm already tuned, I just don't know what kind of mechanical issues could cause this type of behavior.

 

Anybody think this could be a mechanical issue instead of tune related?

 

What fuel are you on?

 

93, this was over the course of two tanks. Logs 3 and 4 were at a different time.

 

Just an update for anyone with similar issues. I replaced the fuel sock, cleaned out the pump housing and started running a tank of injector cleaner which almost solved the issue, I'm still running the cleaner, but take a look for yourselves.

 

Thanks for the update....

I think u have some more power under your Hi Octane Fuel Map if you work on it abit more...

Just a thought.

 

Thanks for pointing that out, I'm working on a few more mods then I'll refine the maps!
