Log Masters! CoBB Help!
I finally got around to installing COBB onto my 135. I'm runnning 93 and the sports map v.401.
I made a couple of logs and i'm seeing a decent amount of timing being pulled. I'm not sure what to do. I figured with 93 gas and sports i'd be on the conservative side. No other mods. The other data pulls I see HEAVY timing changes on cylinder 5 up to about 7 degrees. among 2-3 other cylinders of various amounts. Please take a look and point me in a direction? I'm running mac, so I only have Excel. http://www.datafilehost.com/download-e17aace0.html  Uploaded with ImageShack.us Last edited by Bunyfofu69; 01-26-2013 at 07:37 PM.. |

Posting a link to the actual .csv would be just as, if not more, helpful.

Good news is youre hitting boost targets and afrs looks solid, bad news is youre getting sustained timing corrections across multiple cylinders....try some e85 to smooth out the timing or go to the drive map.

Oh lol. I moved to miami. Haven't updated my location. I did use 2nd tier gas but still 93 on the non aggressive map. Plugs have about 20k. I was just looking up prices to replace.
Could plugs make that much of a difference? With regards to timing? |

Our OEM plugs have knock sensors on the ends of them. If they aren't reading correctly, they can sense false knock. Knock causes timing retard.

OP, you should try running a different brand of gasoline and try grabbing a couple more logs. If you're still getting those corrections with good gasoline in the tank then the plugs would be a good place to start.
