Looking for Car Timing Data
 

Specifically wondering about ignition timing. I threw an ignition trouble code that may be related to the knock sensor. I am wonder what type of advance I should expect to see during closed and open loop operation. Marc has programed a chip to account for port work and freer flowing exhaust but I figure if the knock sensor is retarding timing I should be able to see that in my logged data.

Check out the Tuning Presentation Marc made at this year's Gathering. You can find it on his website under Presentations.
