Thanks for looking at the logs.

3rd gear WOT from today: http://bit.ly/TIzXOx

Will a custom tune eliminate these small corrections at low load? Based on your explanation, it seems that small corrections would always take place at low load due to increased timing for efficiency.

Your WOT pull looks good. Thats when it matter most when cylinder pressures are higher. Notice the timing difference as opposed to in the cruise mode when your running more timing? Your fine from all aspects. The car in closed loop while cruising will run more timing, the cylinder pressures are much much lower and it will not damage the engine. Even with a custom tune you would have small corrections at low load. Most tuners will not even touch that table. Don't forget its perceived knock events too. But its normal for the ECU to go back and forth and correct itself in cruise.

Thanks a lot. I'm new to all of this and wanted to make sure all is good with the car. I was planning on going with a stage 1 protune to have a safer tune but based on what you're telling me and these logs, I don't think I need one as I'm happy with the power levels.

Thanks again for looking at the logs.
